The no of colas that have sold 36 cans.
the translation of the question is :
A merchant obtains €70.50 by selling 57 cans of lemon, 48 of orange and the rest glue. If he sells each can for €0.50, how many colas have you sold?
Total selling price is €70.50
the price of each can is €0.50
So,
the number of cans which is sold is
n = €70.50/€0.50
n = 141 cans
again
the total number of cans = no of lemon + no of orange + no of glue
141 = 57 + 48 + m
m = 36
So the colas have sold 36 cans

The measure of diagonal DB in the given square is 5√2.
What is triangle?A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry. A triangle is defined by its three sides and the three angles formed by those sides. The sum of the three angles in a triangle is always 180 degrees. Triangles can be classified based on the length of their sides and the size of their angles.
Using Pythagoras theorem of right triangle
DB² = DC² + BC²
Here given that
DC = BC
Then
DB² = DC² + DC²
DB² = 5² + 5²
DB² = 25 + 25
DB² = 50

What is the lowest possible value of the house?
A house with value at 210000 correct to 2 significant figures. The lowest possible value of the house is equals to the £205000.
The second significant figure of a number is the digit after the first significant figure. This is true even in case of the digit is zero. We have a house is valued at £210000 correct to 2 significant figures. So, it is bounded question. Since, two significant figures is correct then there is error in 10000 range in £210000. The rounded up value is £2.10 × 10⁵. Steps to determine these bounds
Let assumes that a certain number x must be rounded by a number y. Divide y by 2, i.e. y/2.Upper bound is addition of specific number and y/2, i.e. upper bound = x + y/2.To calculate the lowest value subtract y/2 from the given number, i.e. lower limit = x - y/2.here x = £210000, y = 10000
Since 2 significant digits are correct,
is about 10,000 of £210,000. The lowest possible number rounded to 2 significant digits in the £210,000 range is £205,000, because anything below that looks like £204....that doesn't round up to £21. Hence required value is £205000.

An angle measurement, m∠BOC = 60° degrees where O is the center of the corcle.
What is an angle?
Since the ΔABC has three similar sides, we know that it is an equilateral triangle, meaning that all three angles are equal and each angle measures 60°.
Since A, B, and C are points on a circle with O as the center, we know that each of the distances OA, OB, and OC is equal to the radius of the circle.
Let's call this radius r.
Since ΔABC is equilateral, we know that each side has length r. We can also draw radii from the center O to points A, B, and C to form three congruent triangles AOB, BOC, and COA, each with two sides of length r and one angle of 60°.
Since the sum of the angles in a triangle is 180° degrees, each of the other two angles in each of these congruent triangles must measure 60° as well.
Thus, we see that ∠BOC is one of the angles in the isosceles ΔBOC, which has two angles of 60° and a third angle x, which we want to find.
We can use the fact that the sum of the angles in a triangle is 180° to find x:
x + 60 + 60 = 180
Simplifying, we get:
x = 60
Therefore, angle BOC measures 60°

A group of marine biologists tags 45 great white sharks off the coast of Mexico to study migratory patterns. All of the tag numbers are unique. Weeks later, the marine biologists travel to Hawaii. While there, they randomly capture and release 20 great white sharks per day, for three consecutive days. On the first day, 3 of the sharks have the original tags. On the second day, 2 of the sharks have the original tags. On the third day, 4 of the sharks have the original tags. Based on the data, what is the estimated population of great white sharks that have migrated from Mexico to Hawaii?
Therefore, the estimated population of great white sharks that have migrated from Mexico to Hawaii is 2,500.
What is Shark Population Estimation?Shark population estimation is the process of determining the size and trends of shark populations in a given area. It involves collecting and analyzing data on shark abundance, distribution, behavior, and other factors to understand their population dynamics.
There are different methods used to estimate shark populations, including mark-recapture studies, aerial surveys, acoustic tracking, and genetic analysis. These methods allow researchers to estimate the number of sharks in a given area, monitor changes in their population over time, and identify potential threats to their survival.
To estimate the population of great white sharks that have migrated from Mexico to Hawaii, we can use the capture-recapture method, also known as the Lincoln-Petersen index.

Identify the radius and the center of a circle whose equation is (x â€" 5)² y² = 81. the radius of the circle is units. the center of the circle is at ( , ).
The radius of the circle is 9 units. The center of the circle is at (5, 0).
The given equation is (x – 5)²y² = 81.
To identify the radius and center of this circle, we can rewrite the equation in standard form.
First, let's divide both sides by 81 to get (x – 5)²y²/81 = 1.
Next, we can take the square root of both sides to eliminate the squared terms.
This gives us the equation (x – 5)/9 · y/3 = 1.
The standard form of a circle is (x – h)² + (y – k)² = r², where (h, k) is the center of the circle and r is the radius.
Comparing this form to our equation, we can see that (x – 5)/9 and y/3 correspond to (x – h) and (y – k), respectively.
Therefore, we can solve for h and k by setting (x – 5)/9 = 0 and y/3 = 0, respectively.
This gives us h = 5 and k = 0, so the center of the circle is (5, 0). Finally, we can solve for the radius r by noting that the
distance from the center (5, 0) to the edge of the circle is 3 units in the x-direction and 9 units in the y-direction.
Therefore, the radius of the circle is 9 units, and we can express our final answer as:
The radius of the circle is 9 units. The center of the circle is at (5, 0).

Alexander owes \$3,200$3,200 on his credit card. The bank charges an annual interest rate of 16. 8%, compounded monthly. If Alexander wants to pay off his credit card using equal monthly payments over the next 8 months, what would the monthly payment be, to the nearest dollar?
Alexander would need to make monthly payments of $430 for the next 8 months to pay off his credit card debt.
To calculate the monthly payment that Alexander needs to make, we can use the formula for the present value of an annuity, which is:
[tex]PMT=PV*(r*(1+r)^n)/(1+r)^n-1)[/tex]
Where:
PMT = Monthly payment
PV = Present value of the debt
r = Monthly interest rate
n = Total number of payments
First, we need to calculate the monthly interest rate. The annual interest rate is 16.8%, which means the monthly interest rate is 16.8%/12 = 1.4%.
Next, we can calculate the total number of payments that Alexander needs to make over 8 months.
n = 8
Now, we can plug in the values:
[tex]PMT = 3200*\frac {(0.014*(1+0.014)^8)}{((1+0.014)^8-1)}[/tex]
This works out to approximately $430 per month (rounded to the nearest dollar).
Therefore, Alexander would need to make monthly payments of $430 for the next 8 months to pay off his credit card debt.

Joe has $2500 in a savings account that earns 9% interest per year. How much amount in dollars will he have in 3 years?
To calculate the amount of money Joe will have in 3 years, we can use the formula:
A = P(1 + r/n)^(nt)
where:
A = the amount of money Joe will have in 3 years
P = the principal amount = $2500
r = the annual interest rate = 9% = 0.09 (expressed as a decimal)
n = the number of times the interest is compounded per year (assuming annual compounding, n = 1)
t = the number of years = 3
Plugging in these values, we get:
A = $2500(1 + 0.09/1)^(1*3)
= $2500(1.09)^3
= $2500(1.29503)
= $3237.58 (rounded to two decimal places)
Therefore, Joe will have $3237.58 in 3 years.

Degrees of freedom = (5-1) * (4-1) = 12
Step 5: Determine the p-value:
The p-value is determined by looking up the chi-square value and the degrees of freedom in the chi-square table.
The p-value is the probability of obtaining a result as extreme as or more extreme than the calculated value if the null hypothesis is true.
We will use a 5% level of significance.
Since the calculated value is 15.16, and the degrees of freedom are 12, the p-value is less than 0.05.
As a result, we must reject the null hypothesis.

According to the Fundamental Theorem of Algebra, how many zeros does the function f(x) = 5x^6+2x^3−4x + 1
There are____________ Zeros.
Step-by-step explanation:
According to the Fundamental Theorem of Algebra, a polynomial of degree n has exactly n complex zeros (counting multiplicities).
The degree of the polynomial f(x) = 5x^6+2x^3−4x + 1 is 6, which means that it is a sixth-degree polynomial. Therefore, it has exactly 6 complex zeros (counting multiplicities).
Note that the zeros may be real or complex, and they may not all be distinct. To find the exact number of zeros and their values, we would need to use additional methods such as factoring, the rational zeros theorem, or numerical methods.
Answer:
The Fundamental Theorem of Algebra states that every non-constant polynomial function has at least one complex root. In the case of the polynomial function f(x) = 5x^6+2x^3−4x + 1, it is a sixth-degree polynomial function, which means it has at most six complex roots. However, the Fundamental Theorem of Algebra does not tell us the exact number of roots, nor does it tell us whether the roots are real or complex.
To determine the number of real roots of the function f(x), we can use the Intermediate Value Theorem or graph the function to find the number of times it crosses the x-axis. However, determining the number of complex roots requires more advanced techniques, such as the use of the Fundamental Theorem of Algebra in combination with the Factor Theorem, Rational Root Theorem, or other methods.
Therefore, based on the Fundamental Theorem of Algebra alone, we can say that the function f(x) = 5x^6+2x^3−4x + 1 has at least one complex root, but we cannot determine the exact number or nature of the roots without additional analysis.

The measures of angles in a rhombus are m∠2=130, m∠3=50 and m∠4=50.
What is angle measure?Angle measure is a term used in geometry to describe the size of an angle. It is usually expressed in degrees, which is a unit of measurement for angles. A degree is defined as 1/360th of a complete revolution around a circle.
According to question:In the rhombus, m∠1 =130
In a rhombus, opposite angles are congruent.
The angle opposite to angle 1 is angle 2.
so m∠1 =m∠2
m∠2= 130 degrees
Other pair of opposite angles are also congruent.
so m∠3=m ∠4
We know that the sum of 4 angles = 360

The probability that more than 7 of the 15 patients have hyperextending joints is 0.015, or about 1.5%.
What is probability?
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.
This is a binomial distribution problem, where we have n = 15 trials and the probability of success (a patient having hyperextending joints) is p = 0.2.
A. To find the probability that exactly 5 of the 15 patients have hyperextending joints, we can use the formula for the binomial probability mass function:
P(X = 5) = (15 choose 5) * 0.2^5 * 0.8^10
where (15 choose 5) is the number of ways to choose 5 patients out of 15. Using a calculator, we get:
P(X = 5) = 0.188
So the probability that exactly 5 of the 15 patients have hyperextending joints is 0.188, or about 18.8%.
B. To find the probability that no more than 7 of the 15 patients have hyperextending joints, we need to add up the probabilities of having 0, 1, 2, ..., 7 patients with hyperextending joints. We can use the cumulative distribution function (CDF) of the binomial distribution:
P(X ≤ 7) = Σ(P(X = k)) for k = 0 to 7
Again, using a calculator, we get:
P(X ≤ 7) = 0.985
So the probability that no more than 7 of the 15 patients have hyperextending joints is 0.985, or about 98.5%.
C. To find the probability that more than 7 of the 15 patients have hyperextending joints, we can use the complement rule:
P(X > 7) = 1 - P(X ≤ 7)
We already know from part (B) that P(X ≤ 7) = 0.985, so:
P(X > 7) = 1 - 0.985 = 0.015
Therefore, the probability that more than 7 of the 15 patients have hyperextending joints is 0.015, or about 1.5%.

How do you find the Surface area of a rectangular prism make it simple and correct answer gets brainliest
The rectangular prism's length, width, and height can also be labelled, and the surface area (SA) can be calculated using the formula:
SA = 2lw+2lh+2hw.
Explain about the rectangular prism?A face is just a flat surface in the geometric sense, and edges are formed where surfaces meet. Pyramids and prisms are both examples of polyhedra. A pyramid, however, is not a prism.
A polyhedron having two identical and parallel faces is referred to as a prism.A rectangular prism is one of the more typical shapes for prisms. One definition of a rectangular prism is a prism with rectangle-shaped bases. An other faces also were rectangles because the bases are rectangles.Method to find surface area:
A three-dimensional shape's surface area is the total area on its surface. Add these areas of each of the six rectangular sides of a cuboid to determine its surface area.Thus, the rectangular prism's length, width, and height can also be labelled, and the surface area (SA) can be calculated using the formula:
SA = 2lw+2lh+2hw.

Write a polynomial function in standard form with zero's -5,-4,and 3
The equation of the polynomial function in standard form is P(x) = x³ + 6x² - 7x - 60
Calculating the polynomial function in standard formGiven that we have the following
zeros = -5,-4,and 3
The polynomial function in standard form is calculated as
P(x) = (x - zeros)
So, we have
P(x) = (x + 5)(x + 4)(x - 3)
Opening the brackets, we have the following equation
P(x) = x³ + 6x² - 7x - 60
Hence, the polynomial is P(x) = x³ + 6x² - 7x - 60

Answer:
a) v.h=v*cos(63)=7.26 m/s
b) v.v=v*sin(63)=14.26 m/s
c) t=v.v/g=14.26/9.8=1.46 s since time the body takes to go upward is defined by the acceleration due to gravity and the vertical component of the speed
d) h=1/2*gt^2=7.15 m
e) T=2t=2.92 s
f) R=v.h*t=7.26*1.46=10.6 m since horizontal displacement is defined by the horizontal component of the speed only.
