robbie had 5.00 to spend on lunch.He bought a hamburger for 1.26 potato chips for 65 cents and 2 drinks for 85 cents each how much money did he get back

Answer:

Step-by-step explanation:

The president, vice-president, secretary and treasurer are four different positions that need to be filled by ten individuals.

Therefore, the number of ways to elect the president is 10. After electing the president, the number of candidates available for the vice-president position reduces to 9. Similarly, after electing the president and the vice-president, the number of candidates available for the secretary position reduces to 8. Finally, after electing the president, vice-president, and secretary, the number of candidates available for the treasurer position reduces to 7.

Using the multiplication principle of counting, we can find the total number of possible combinations for all four positions by multiplying the number of candidates for each position:

Total number of ways to elect all four positions = (number of candidates for president) x (number of candidates for vice-president) x (number of candidates for secretary) x (number of candidates for treasurer)

= 10 x 9 x 8 x 7

= 5,040

Therefore, there are 5,040 different ways that Sea Esta can elect a president, vice-president, secretary, and treasurer from its board of directors.

So the three integers are 4, 6, and 8 such that 6 times the first integer is 10 more than the sum of the second and the third integers.

An integer is a whole number that does not have any fractional or decimal parts. Integers include positive numbers (1, 2, 3, etc.), negative numbers (-1, -2, -3, etc.), and zero (0).

Here,

Let's call the first even integer x. Since the three integers are consecutive even integers, the second and third integers are x + 2 and x + 4, respectively.

From the problem statement, we know that:

6x = (x + 2) + (x + 4) + 10

Simplifying the right side of the equation:

6x = 2x + 16

Subtracting 2x from both sides:

4x = 16

Dividing both sides by 4:

x = 4

The entire number of kilometres driven by Roland's family can be determined by using the phrase [tex]=\frac{69}{10}[/tex]

To determine the total number of kilometres driven by Roland's family, the distance from their home to the gas station and the distance from the gas station to the shop must be added.

There are [tex]4\times \frac{6}{10}[/tex] kilometres between their home and the gas station, which can also be stated incorrectly as follows:

[tex]4\times \frac{6}{10}=\frac{(4\times 10+6)}{10} \\\\=\frac{46}{10}[/tex]

The formula for expressing the distance between the gas stop and the store is 2 30/100 kilometers, which can be written as follows:

[tex]2\times\frac{30}{100} =\frac{(2\times100+30)}{100} \\\\=\frac{230}{100}[/tex]

To calculate the overall distance traveled, we add the two distances:

[tex]\frac{46}{10} +\frac{230}{100}[/tex]

To combine these fractions, we need to find a common denominator. Only one unique digit, 100, can be used to divide both 10 and 100. In light

of this, we can rewrite the equation as follows using 100 as the common denominator:

[tex](\frac{46}{10} )\times (\frac{10}{10} )+(\frac{230}{100} )\times (\frac{1}{1} )[/tex]

That amounts to:

[tex]\frac{46}{100} +\frac{230}{100} =\frac{690}{100}[/tex]

[tex]\frac{690}{100} =\frac{(69/10)}{(100/10)} \\\\=\frac{69}{10}[/tex]

Consequently, the phrase that follows may be used to determine the overall number of kilometres driven by Roland's family:

Answer:

Rusty Raspberry's total earnings last year would be the sum of his earnings from playing baseball and his earnings from book royalties.

Earnings from playing baseball = $1,715,000

To calculate earnings from book royalties, we need to find out how much Rusty received in royalties for the 300,000 copies sold.

Royalties per book = 10% of $24 = $2.40

Total royalties for 300,000 books = $2.40 x 300,000 = $720,000

Therefore, Rusty Raspberry's earnings from book royalties last year = $720,000

Total earnings = Earnings from playing baseball + Earnings from book royalties

= $1,715,000 + $720,000

= $2,435,000

Therefore, Rusty Raspberry's total salary last year from the book and his baseball career was $2,435,000.

Each interior angles of the rectangle QUAD is equal to 90°, and the angles ∠2 and ∠5 are complementary, so the value of x = 4.

The angles ∠2 and ∠5 form one of the interior angles of a rectangle, hence they are complementary as they add up to 90°.

we shall solve for x as follows:

x + 30 + 2x - 48 = 90

3x + 78 = 90

3x = 90 - 78 {subtract 78 from both sides}

3x = 12

x = 12/3 {divide through by 3}

Answer:$59.66

Step-by-step explanation:

Answer:

Step-by-step explanation:

A = P(1 + r/n)^(n*t)

where:

A = the future value of the investment

P = the principal amount (the initial investment)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years the money is invested

In this case, we have:

P = $6,000.00

r = 4% = 0.04

n = 4 (compounded quarterly)

t = 7 years

So the formula becomes:

A = $6,000.00(1 + 0.04/4)^(4*7)

A = $6,000.00(1 + 0.01)^28

A = $6,000.00(1.01)^28

A = $8,199.11 (rounded to the nearest cent)

Therefore, you will have $8,199.11 in the account in 7 years.

Step-by-step explanation:

Eva is not correct. There is only one possible triangle that can be formed with the given information. This is because in a triangle, the length of any side must be less than the sum of the lengths of the other two sides.

Using the Law of Cosines, we can find the length of the unknown side, c:

c^2 = a^2 + b^2 - 2ab cos(ZA)

c^2 = 54^2 + 59^2 - 2(54)(59) cos(130°)

c ≈ 31.28

Since h < a < b, we know that h < 54 < 59. Therefore, the length of side c must be between 5 and 113 (59 - 54 and 59 + 54). Since c = 31.28 is between 5 and 113, it satisfies the triangle inequality and a triangle can be formed.

To find the measures of the other angles, we can use the Law of Sines:

sin(A)/a = sin(ZA)/c

sin(A) = (a/c)sin(ZA)

sin(A) = (54/31.28)sin(130°)

sin(A) ≈ 0.879

A ≈ 62.6°

Similarly,

sin(B)/b = sin(ZA)/c

sin(B) = (b/c)sin(ZA)

sin(B) = (59/31.28)sin(130°)

sin(B) ≈ 0.841

B ≈ 56.2°

Therefore, the measures of the three angles are approximately 62.6°, 56.2°, and 61.2°, and there is only one possible triangle that can be formed with these side lengths and angle measures.

A circle is a geometric shape in a two-dimensional plane, consisting of all the points that are at a fixed distance, called the radius, from a given point, called the center. The distance around the circle is called the circumference. The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle, and π (pi) is a mathematical constant approximately equal to 3.14159. The formula for the area of a circle is A = πr^2, where r is the radius of the circle. Circles have many real-world applications, such as in the design of wheels, gears, and other rotating objects. They are also important in mathematics and science, as they provide a simple and elegant way to study and understand the properties of curves and curved surfaces.

We can approach this problem by considering a vertical slice of the solid taken perpendicular to the y-axis. This slice will be an equilateral triangle with a side length that depends on the y-coordinate.

At y = 0, the circle x² + y² = 16 intersects the x-axis at x = ±4. This means that the equilateral triangle at y = 0 has side length 2√3 times the distance from the origin to the x-axis, which is 4√3. Therefore, the area of this triangle is:

A(0) = (√3/4) (4√3)² = 12√3

At a general y-coordinate y > 0, the equilateral triangle will have side length equal to the distance between the points where the circle intersects the line y = k, where k is the y-coordinate. This distance can be found using the Pythagorean theorem:

d = √(16 - k²) - √k² = √(16 - 2k²)

The area of the equilateral triangle at y is then:

A(y) = (√3/4) d² = (√3/4) (16 - 2k²)

To find the volume of the solid, we can integrate the cross-sectional areas with respect to y from 0 to 4, using the formula for the area of an equilateral triangle:

V = ∫(0 to 4) A(y) dy = ∫(0 to 4) (√3/4) (16 - 2k²) dy

= (√3/4) (16y - (2/3) y³)|0 to 4

= (√3/4) [(64 - (2/3)(64)) - (0 - 0)]

Answer:

Step-by-step explanation:

To find the utility-maximizing bundle of goods, we need to solve for the values of x and y that maximize U while still satisfying the budget constraint. The budget constraint can be written as:

2x + 4y = 24

or

x + 2y = 12

We can use the method of Lagrange multipliers to solve for the utility-maximizing values of x and y subject to this constraint. The Lagrangian function is:

L = 3x^(2/3)y^(-1/3) + λ(x + 2y - 12)

Taking partial derivatives with respect to x, y, and λ, we get:

dL/dx = 2x^(-1/3)y^(-1/3) + λ = 0

dL/dy = -x^(2/3)y^(-4/3) + 2λ = 0

dL/dλ = x + 2y - 12 = 0

Solving these equations simultaneously, we get:

x = 6

y = 3

So the utility-maximizing bundle is 6 units of x and 3 units of y.

To see if the individual is better off with the government intervention, we can plot the budget line and the indifference curve for the utility-maximizing bundle with and without the limit on x.

Without the limit, the budget line is the same as before (x + 2y = 12), and the indifference curve for the utility-maximizing bundle passes through the point (6, 3) on the graph.

With the limit, the budget line becomes x = 4, since the individual is prohibited from purchasing more than 4 units of x. The corresponding budget line has a slope of -1/2 and intercepts the y-axis at 6.

If we draw the indifference curve for the utility-maximizing bundle of (4,4), which lies on the budget line, we can see that the individual is not better off with the government intervention. This is because the slope of the budget line under the intervention is steeper, so the individual would have to give up more y than x to afford the same amount of utility. Thus, the individual would have to move to a lower indifference curve with lower utility.

Therefore, the individual is not better off with the government intervention.

The zeros of the function H(x) = (3x - 4)(x + 2)^2(x - 5) are (4/3, 0), (-2, 0), and (5, 0).

To find the zeros of the function H(x), we need to find the values of x that make the function equal to zero.

H(x) = (3x - 4)(x + 2)^2(x - 5)

Setting H(x) equal to zero, we have:

(3x - 4)(x + 2)^2(x - 5) = 0

Using the zero product property, we can see that H(x) will be equal to zero when any of the factors are equal to zero.

So, the zeros of the function H(x) are:

3x - 4 = 0, which gives x = 4/3

x + 2 = 0, which gives x = -2

x - 5 = 0, which gives x = 5

Therefore, the zeros of the function H(x) are (4/3, 0), (-2, 0), and (5, 0).

Step-by-step explanation:

To find the number of miles at which the cost to rent either car would be the same, we can set the two cost equations equal to each other and solve for m:

0.60m + 10 = 0.40m + 22

0.20m = 12

m = 60

So, the number of miles at which the cost to rent either car would be the same is 60 miles.

To find the cost at this mileage, we can plug m = 60 into either of the cost equations:

For the compact car:

C = 0.60(60) + 10 = 46

For the midsized car:

C = 0.40(60) + 22 = 46

So, at 60 miles, the cost to rent either car would be $46.

The value of x in the triangle is 16.

Inputting the values provided yields:

8/x = 12/24

When the right-hand side of the equation is simplified, we obtain:

12/24 = 1/2

Adding this value to the proportion results in:

8/x = 1/2

If we cross-multiply, we obtain:

2*8 = x

The left side of the equation can be simplified to: 16 = x.

The remainders of the polynomial divison are 18, -9, 10 and 0 and the factor are (x + 2)(3x² + 2x - 1) and (x - 2)(x² - 2x - 15)

The remainder theorem states that

Given the polynomial f(x) divided by x - a, the remainder is b if

f(a) = b

So, we have

Polynomial (10)

(x² + 9) ÷ (x - 3)

Remainder = 3² + 9

Remainder = 18

This means that

x - 3 is not a factor of (x² + 9)

Polynomial (11)

(x³ - 4x + 6) ÷ (x + 3)

Remainder = (-3)³ - 4(-3) + 6

Remainder = -9

This means that

x + 3 is not a factor of (x³ - 4x + 6)

Polynomial (12)

(x⁴ + 4x³ + 16x - 35) ÷ (x + 5)

Remainder = (-5)⁴ + 4(-5)³ + 16(-5) - 35

Remainder = 10

This means that

x + 5 is not a factor of x⁴ + 4x³ + 16x - 35

Polynomial (13)

(2x³ - 10x² - 71x - 9) ÷ (x - 9)

Remainder = 2(9)³ - 10(9)² - 71(9) - 9

Remainder = 0

This means that

x - 9 is a factor of 2x³ - 10x² - 71x - 9

Multiply -2 by 3 to get -6, and write it below the next coefficient and repeat the process

-2 |   3    8   3  -2

    |____-6_-4_2____

       3     2 -1     0

So, the factor is (x + 2)(3x² + 2x - 1)

Polynomial (15)

Using a synthetic method of quotient, we have the following set up

2 |   1    -4   -11  + 30

   |__________

Multiply 2 by 1 to get 3, and write it below the next coefficient and repeat the process

2 |   1    -4   -11  + 30

   |____2__-4_-30__

       1    -2    -15   0

So, the factor is (x - 2)(x² - 2x - 15)
