If d=3 what is the answer? 7b to the power of three +10

Sati [7]

Answer:

199 if it's 7b^3 + 10

9271 if it's (7b)^3 + 10

Step-by-step explanation:

You just substitute the 3 in for d. If your expression was 7b^3 + 10, then only b is being raised to 3.

So 3^3 is 27, 27*7 is 189, 189+10 is 199.

If the expression was (7b)^3 + 10, then first you multiply 7 and 3 to get 21. Then you raise 21 to the power of 3, which is 9261. Then you add 10, which is 9271.

A muffin recipe, which yields 12 muffins, calls for 2/4 cup of milk for every 1 3/4 cups of flour. The same recipe calls for 1/4

mezya [45]

Answer:

b) 4 3/8

Step-by-step explanation:

we know that

12 muffins calls for 1 3/4 cups of flour

using proportion

Find out how much flour will be needed in the mix for a bath of 30 muffins

$\frac{12}{1\frac{3}{4}}=\frac{30}{x}\\\\x=30(1\frac{3}{4})/12$

Convert mixed number to an improper fraction

$1\frac{3}{4}=1+\frac{3}{4}=\frac{7}{4}$

substitute

$x=30(\frac{7}{4})/12\\\\x=\frac{210}{48}\ cups\ of\ flour$

convert to mixed number

$\frac{210}{48}=\frac{192}{48}+\frac{18}{48}=4\frac{3}{8}\ cups\ of\ flour$
