Answer: 150 ounces of sugar

Step-by-step explanation:

75 divided by 45 is 1.7 ounces, that means one cupcake has approximately 1.7 ounces in it. So 255 divided by 1.7 gives us 150 ounces.

Solution:

Ounces of Sugar used by Amanda to make 75 cupcakes = 45 Ounces

As, number of ounces of sugar is in Direct variation with number of cupcakes.

The meaning of direct variation is , the ratio of two variables in each case is same.

Here , Ratio of ounces of sugar, to number of cupcakes in each case will be same.

Let number of ounces of sugar which will be used to make 255 cupcakes be x ounces.

$\frac{45}{75}=\frac{x}{255}\\\\ \frac{3}{5}=\frac{x}{255}\\\\ x=\frac{255 \times 3}{5}\\\\ x=\frac{765}{5}\\\\ x=153$

So, Number of ounces of sugar which will be used to make 255 cupcakes = 153 ounces.

Rectangle area w algebra step by step explanation please :)

Natalija [7]

We know that the area is 20.

Since 20 is a small number: lets list out possible combinations of lengths and widths.

1 * 20

2 * 10

4 * 5

L = 7 + 3w

lets see which on makes sense.

L = 7 + 3w

20 = w7 + 3w^2

3w^2 + 7w -20 = 0

(3w - 10)(w - 2)

w can equal 10/3 or 2.

So the dimensions: are Width = 2 Length = 10

Helga [31]

Answer:

The equation representing the value of n is, $n=\frac{S}{180^{\text{o}}}+2$ .

Step-by-step explanation:

The formula to compute the sum of the degrees, S, of the interior angles of a polygon is:

$S=(n-2)\times 180^{\text{o}}$

Compute the equation of n as follows:

$S=(n-2)\times 180^{\text{o}}$

$\frac{S}{180^{\text{o}}}=(n-2)$

$n=\frac{S}{180^{\text{o}}}+2$

Thus, the equation representing the value of n is, $n=\frac{S}{180^{\text{o}}}+2$ .
