Answer:

$\frac{3375}{512}$ or ≈6.59

Step-by-step explanation:

We can first begin by simplifying each of the numbers with exponents. Recall that in a fraction exponent, the numerator is the power, while the denominator is the root.

Take $25\frac{3}{2}$ for example. The '2' in the fraction means we must take the square of 25. √25 = 5.

The '3' in the fraction means we take the power, which means we must cube '5'.

5³ = 125. Therefore, $25\frac{3}{2}$ = 125. Use this process for the other numbers:

$25^{\frac{3}{2} } = 125\\243^{\frac{3}{5} } = 27\\16^{\frac{5}{4} } = 32\\ 8^{\frac{4}{3} } = 16$

The new fraction would look like:

$\frac{125 * 27}{32 * 16}$

Which simplifies to:

$\frac{3375}{512}$ or ≈6.59

Write the expression for when you translate the graph of y = |3x|− 5 one unit to the right.

DedPeter [7]

Answer:

$y=|3x-3|-5$

Step-by-step explanation:

Notice that we are requested to perform a horizontal shift of on unit to the right. Recall that a horizontal shift of one unit to the right involves the operation of subtracting from the variable "x" one unit.

Therefore, this implies the following mathematical transformation to the variable "x":

$y=|3(x-1)|-5\\y=|3x-3|-5$

where we simply completed distributive property to get rid of the parenthesis inside the absolute value.

In your quilt shop,you make and sell quilts. You like to have a total of 26 yards of royal blue fabric in stock at the beginning

Vera_Pavlovna [14]

Answer:

7 pieces

Step-by-step explanation:

Stock that must be available at the beginning of each month = 26 yards

Since,

1 yard = 36 inches

26 yards = 26 x 36 = 936 inches

This means 936 inches of fabric must be available at beginning of each month.

Current Inventory:

4 pieces that are each 22 1/2 (or 22.5) inches long. So total length of these fabrics = 4 x 22.5 = 90 inches

3 pieces that each 33 inches long. So total length of these fabrics = 3 x 33 = 99 inches

Therefore, the total length of current inventory = 90 + 99 = 189 inches.

Length of fabric needed more:

Length of fabric that must be bought more = 936 - 189 = 747 inches

It is given that the fabric must be bought in pieces are the 3 yards long. 3 yards is equal to 108 inches.

So, I have to buy pieces that are each 108 inches long and I need to complete 747 inches in total.

Therefore, the number of pieces that I need to buy = $\frac{747}{108}=6.9$

Since, the pieces cannot be bought in fraction, I need to buy 7 complete pieces to replenish my stock.
