The fraction of the original melon that was used to make each fruit cup is 1/5, as there was one piece left after giving each of the four children their share.

Mrs. Sims cut a melon into fifths and gave 1 piece to each of her four children. Therefore, there would be one piece of the melon left after giving each child a piece.

To determine the fraction of the original melon used to make each fruit cup from the leftover piece, we simply need to account for the remaining melon. As there is only one piece left out of the original five pieces, the fraction of the original melon used for each fruit cup is 1/5.

The fraction 27/22, when converted into a decimal and rounded to the nearest tenth, is approximately 1.2.

To convert a fraction to a decimal, divide the numerator by the denominator. In this case, divide 27 by 22.

The question asks to convert the fraction 27/22 into a decimal, rounded to the nearest tenth. First off, we calculate the division of 27 by 22, which gives us approximately 1.227. However, we need to round this figure to the nearest tenth, which results in the value of 1.2. Be sure to understand that when we say 'rounded to the nearest tenth', we refer to the first digit after the decimal point.

The table B represent an inverse variation  

The constant of variation k is 30

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form [tex]y*x=k[/tex] or [tex]y=k/x[/tex]

Verify table A

For x=3, y=8 ----> [tex]k=y*x[/tex] ----> [tex]k=8*3=24[/tex]

For x=4, y=6 ----> [tex]k=y*x[/tex] ----> [tex]k=6*4=24[/tex]

For x=5, y=4.8 ----> [tex]k=y*x[/tex] ----> [tex]k=4.8*5=24[/tex]

For x=5.5, y=4 ----> [tex]k=y*x[/tex] ----> [tex]k=5.5*4=22[/tex]

The values of k are different

therefore

The table A not represent an inverse variation  

Verify table B

For x=0.1, y=300 ----> [tex]k=y*x[/tex] ----> [tex]k=300*0.1=30[/tex]

For x=0.5, y=60 ----> [tex]k=y*x[/tex] ----> [tex]k=60*0.5=30[/tex]

For x=75, y=0.4 ----> [tex]k=y*x[/tex] ----> [tex]k=75*0.4=30[/tex]

For x=100, y=0.3 ----> [tex]k=y*x[/tex] ----> [tex]k=100*0.30=30[/tex]

All the values of k are the same

therefore

The table B represent an inverse variation

The equation [tex]A=5000(1.000958333)^{108}[/tex] will determine how much money Bevo will have in his account after 9 years

Step-by-step explanation:

The formula for compound interest, including principal sum is

[tex]A=P(1+\frac{r}{n})^{nt}[/tex] , where:

Bevo has $5000 to invest. Bank A offers a savings account that has an APR of 1.15% and compounds monthly

We need to find Which equation will determine how much money Bevo will have in his account after 9 years

Because there is no choices we will write the equation

∵ Bevo has $5000 to invest

∴ P = 5000

∵ Bank A offers a savings account that has an APR of 1.15%

   and compounds monthly

∴ r = 1.15% = 1.15 ÷ 100 = 0.0115

∴ n = 12 ⇒ compounds monthly

∵ t = 9

- Substitute all of theses values in the formula below

∵ [tex]A=P(1+\frac{r}{n})^{nt}[/tex]

The simplified expression of 3z + (3/4) - 2z is z + (3/4).

The expression 3z + (3/4) - 2z can be simplified by combining like terms. Like terms have the same variable and exponent. In this case, the like terms are the 3z and the -2z. When you combine them, you get z. So the simplified expression is z + (3/4).

To find the coordinates of point P along the directed line segment AB so that AP to PB is in the ratio 3 to 1, we use the section formula. Substituting the values into the formula, we find that the coordinates of point P are (-1, -2).

To find the coordinates of point P along the directed line segment AB so that AP to PB is in the ratio 3 to 1, we can use the concept of section formula.

The section formula states that if we have two points A(x1, y1) and B(x2, y2), and we want to find a point P along the line segment AB such that AP to PB is in the ratio m to n, then the coordinates of P can be found using the following formulas:

x = (mx2 + nx1) / (m + n)

y = (my2 + ny1) / (m + n)

In this case, A(-4, -8) and B(0, 0).

Let's substitute the values into the formula:

x = (3 * 0 + 1 * -4) / (3 + 1) = -4/4 = -1

y = (3 * 0 + 1 * -8) / (3 + 1) = -8/4 = -2

Therefore, the coordinates of point P are (-1, -2).

Final answer:

To find point P on line segment AB where AP:PB = 3:1, we use section formula to get P's coordinates as (-1,-2). This method applies interpolation of the endpoints' coordinates, A(-4,-8) and B(0,0), by their respective weights in the given ratio.

Explanation:

To find the coordinates of point P on the directed line segment AB such that the ratio of AP to PB is 3 to 1, we can use the section formula which combines the x and y coordinates of A and B weighted by the given ratio, since P divides AB internally in the ratio 3:1.

The coordinates of A are (-4, -8) and the coordinates of B are (0, 0). Using the section formula, we can find the coordinates of P as follows:

Let x and y be the coordinates of P.

The x-coordinate of P is given by ((3 * 0) + (1 * (-4))) / (3 + 1) = -1.

The y-coordinate of P is given by ((3 * 0) + (1 * (-8))) / (3 + 1) = -2.

Therefore, the coordinates of P are (-1, -2).

This process involves interpolation of the given points in the specific ratio to find the required coordinates.

Final answer:

Manny and Jane will take approximately 2.1 hours to complete the job together.

Explanation:

To find out how long it will take Manny and Jane to complete the job together, we need to determine their combined rate of work. Manny can complete the job in 7 hours, so his work rate is 1/7 of the job per hour. Jane can complete the job in 3 hours, so her work rate is 1/3 of the job per hour. To find their combined rate, we add their individual rates: 1/7 + 1/3 = 3/21 + 7/21 = 10/21.

Since their combined work rate is 10/21 of the job per hour, it will take them 21/10 hours to complete the job together. Simplifying this fraction, we get 2.1 hours. Therefore, it will take Manny and Jane approximately 2.1 hours to complete the job together.

Answer:

Step-by-step explanation:

If f(x) = x, then f(x) - 5 = x - 5.

The two functions in slope-intercept form (y = mx+ b) are:

[1] y = x     and     [2] y = x - 5

In equation [1], the slope is 1 and the y-intercept is 0.

In equation [2], the slope is 1 and the y-intercept is -5.

a. The y-intercepts are not the same. 0 ≠ -5

b. The rates of change, or the slopes, are the same, neither are greater than the other. 1 = 1

c. They are parallel lines. Lines are parallel when they have the same slope.        1 = 1.

d. The (-5) indicates that the new function is translated down (-) by 5 units (5) from the parent function f(x) = x.

Step-by-step explanation:

Thirteen more than three times a number can be written as (3x+13).

The difference between -29 and three times the number can be written as (-29-3x).

Then set them equal and solve.

3x+13=(-29)(-3x)

3x=(-42)(-3x)

6x=(-42)

x=-7

The algebraic equation of the statement is 3x + 13 = -29 - 3x and the solution is x = -7.

Given the parameter:

Thirteen more than three times a number is equal to the difference between -29 and three times the number.

Let 'x' represent the unknown number:

Now, let's translate the given sentence into an algebraic equation.

Thirteen more than three times a number ⇒ 3x + 13

equal to the difference between -29 and three times the number ⇒ = -29 - 3x

Now, we combine:

3x + 13 = -29 - 3x

We solve for x:

3x + 3x = -29 - 13

49152

Step-by-step explanation:

To find the 15th term of the geometric sequence 3, -6, 12, ..., we identify the common ratio as -2 and use the formula for the nth term of a geometric sequence. By calculating 3 * (-2)^14, we find that the 15th term is 49152.

To find the 15th term of the geometric sequence 3, -6, 12, ... we first need to determine the common ratio. By dividing the second term by the first term, we find that the common ratio is -2.

Formula for the nth term of a geometric sequence:

an = a1 × r(n-1), where an is the nth term, a1 is the first term, r is the common ratio, and n is the term number.

Finding the 15th term:

Plugging in the values, we get: a15 = 3 × (-2)(15-1) = 3 × (-2)14. Since (-2)14 is positive (because any even power of a negative number is positive), the 15th term will be positive. Calculating the value, a15 = 3 × 16384 = 49152.

Therefore, the 15th term of the geometric sequence is 49152.
