Lemon quah ha 2 part of concentrate to 5 part of water, if you put 90ml of concentrate in a gla, how much water hould be added?
Based on the 2:5 quantity of concentrate and water, the amount of water required for 90 mililitres will be 225 mililitres of water.
Firstly we will be creating the ratio for the mentioned information. It will be as follows-
Amount of concentrate/Amount of water
The proportion will be -
2/5 = 90/Concentration of water
Concentration of water = 90×5/2
Now perform multiplication in numerator on Right Hand Side of the equation
Concentration of water = 450/2
Then work out the division on Right Hand Side of the equation
Concentration of water = 225 mililitres
Thus, the required amount of water is 225 mililitres.

A right cylinder has a radius of 12 units and a height of 15 units. What is the total surface area, in units squared?
Answer:
2034.72 units²
Step-by-step explanation:
Formula for surface area of a cylinder is:
2πrh + 2πr²
The radius is 12 and the height is 15, so we plug it in:
2π(12·15) + 2π(12)²
2π(12·15) + 2π(12)²=2034.72.
Brady tosses a coin three times. Each toss could be heads or tails. Which
outcome would be included in the compound event "at least two tails"?
The outcome for the event "at least two tails" is HTT. Option B
A sample space is a set of potential results from a random experiment. The letter "S" is used to denote the sample space. Events are the subset of possible experiment results. Depending on the experiment, a sample area could contain a variety of results. Discrete or finite sample spaces are those that have a finite number of outcomes.
HHH → All heads
HHT → Two heads + one tail
HTH → Two heads + one tail
HTT → Two tails + one head
THH → One tail + two heads
THT → Two tails + one head
TTH → Two tails + one head
TTT → All tails
Therefore, At least two tails means → Sample space outcome with two tails Or all tails
Therefore, from the given options HTT is having two tails. Option B is the correct option.

Cameron's scout leader organized a contest to see who could build the strongest boat out of aluminum foil. After building their boats, the scouts measured how many pennies the boats could support before sinking. This box plot shows the results.
Answer:
1/4
Step-by-step explanation:
In a box plot, each whisker represents
1
4

1

of the boats could support 12 or more pennies.
The pennies can be added to the boat before it sinks is 10.
What is volume?Volume is a degree of occupied three-dimensional area. its miles are regularly quantified numerically with the use of SI-derived devices or with the aid of various imperial devices. The definition of the period is interrelated with the extent.
here, we have,
Density is the substance's mass according to a unit of volume. The image most customarily used for density is ρ, even though the Latin letter D also can be used. Mathematically, density is described as mass divided with the aid of the extent
Mass of aluminum boat = 16.5 gram
Volume = 425 cm³
Density = mass/ volume
= 16.5/425
= 0.039 gcm⁻³
The density of water and boat must be equal or more in order of sinks.
The density of water = 1 gcm⁻³
1 gcm⁻³ = mass × 0.039
mass = 1/ 0.039
mass = 25.64 g
A total of 25.64 grams of mass can be added.
mass of each penny = 2.5 g
Therefore the total number of pennies that can be added is = 25.64 /2.5
= 10.256
Taking the whole number = 10 pennies can be added o the boat before it sinks

What are the potential solutions of In(x^2-25)=0?
Answer:
[tex] x =\pm \sqrt{26}[/tex]
Step-by-step explanation:
Given :-
ln ( x² - 25 ) = 0And we need to find the potential solutions of it. The given equation is the logarithm of x² - 25 to the base e . e is Euler's Number here. So it can be written as ,
Equation :-
[tex]\implies log_e {(x^2-25)}= 0 [/tex]
In general :-
If we have a logarithmic equation as ,[tex]\implies log_a b = c [/tex]
Then this can be written as ,
[tex]\implies a^c = b [/tex]
In a similar way we can write the given equation as ,
[tex]\implies e^0 = x^2 - 25 [/tex]
Now also we know that [tex]a^0 = 1[/tex] Therefore , the equation becomes ,[tex]\implies 1 = x^2 - 25 \\\\\implies x^2 = 25 + 1 \\\\\implies x^2 = 26 \\\\\implies x =\sqrt{26} \\\\\implies x = \pm \sqrt{ 26}[/tex]
Hence the Solution of the given equation is ±√26.

Answer:
H) {8, 9, 10, 11, 12}
Step-by-step explanation:
The domain of a problem is the set of all possible values that can be the input of a given function. In this case, the problem asks for the number of volleyball players are on a team. Since one cannot have a fraction of a person, then the domain must be a set of whole numbers. Moreover, the problem gives one the information that there has to be at least (8) players, and no more than (12). Thus, the only option that satisfies all of these requirements is option (H). Therefore the correction option is the following,
H) {8, 9, 10, 11, 12}
The missing base of 81= ^2
Answer:
the correct answer is 9²
Answer:
9
Step-by-step explanation:
It is stating that 81 is equal to x², in which the variable x stands for a number.
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x, by rooting both sides:
√x² = √81
x = √81 = √(9 * 9) = 9
9 is your missing base.

A grocery store has increased its prices over time. The price per pound of apples in 2016 was $0.45. Today, the price per pound of apples is $0.85.
What is the equation of the line that would represent the price increase per pound of apples over time?
Answer:
C = 0.06x + 0.45
Step-by-step explanation:
Today is 2023
So, from 2016 to 2023, it has been 7 years.
0.85 - 0.45 = $0.40
So, $0.40 is the increase in 7 years
0.40 / 7 = $0.06
So, $0.06 is the change per year
Let C represent the total cost and x represent the number of years and we have
C= 0.06x + 0.45

Find the equation of the circle whose center and radius are given.
center ( -2, -5), radius = 1
Answer:
(x + 2)^2 + (y + 5)^2 = 1
Step-by-step explanation:
Since this circle is centered at (-2, -5), we have to add values within the squares. The standard form of a circle equation is:
(x - h)^2 + (y - k)^2 = r^2
So -2 is h and -5 is k. Substituting that in we get:
(x + 2)^2 + (y + 5)^2 = r^2
We are given the radius is 1, and one squared is one, so the final equation is:
(x + 2)^2 + (y + 5)^2 = 1

Which of the following are the factors of the equation x 2 3x − 4 0?
(A) (x+4)(x-1)=0 is the proper factors form of the given equation x²+3x-4=0.
What are the factors?A factor is a number that completely divides another number.
To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product because the product is divisible by them.
So, we have the equation:
x²+ 3x - 4 = 0
By dividing the center term, this quadratic equation can be reduced to its simplest form.
The result of dividing the middle word is:
x² + 4x - x - 4 = 0
One way to spell it is as:
x (x + 4) - 1 (x + 4) = 0
Now, we obtain:
(x + 4) (x - 1) = 0
Therefore, (A) (x+4)(x-1)=0 is the proper factors form of the given equation x²+3x-4=0.

A circle is the set of all points that are the same distance from one given point. Find an example that contradicts this definition. How would you change the definition to make it more accurate?
An example that contradicts this definition would be an ellipse that set all points such that the sum of the distances between the point and two other fixed points (called foci) is constant.
What is the equation of a circle?The equation of a circle with center (h,k) and radius r is :
r² = (x−h)² + (y−k)²
A circle is defined as the set of all points that are the same distance from one given point, called the center of the circle. An example that contradicts this definition would be an ellipse, which is defined as the set of all points such that the sum of the distances between the point and two other fixed points (called foci) is constant.
An ellipse is not a circle since all points of an ellipse are not equidistant to the center point
To make the definition more accurate, it could be modified to say "A circle is defined as the set of all points that are a fixed distance from one given point, called the center of the circle." or "A circle is defined as the set of all points such that the distance between the point and the center is constant"
