15. A restaurant has one type of milk that has 2% fat and another that has 7% fat. how many quarts of each type does the restaur

krek1111 [17]

<span>B. 16 quarts of the 2% milk and 24 quarts of the 7% milk First, let's create an equation to solve. x = quarts of 2% milk (40-x) = quarts of 7% milk So we have the equation x*2 + (40-x)*7 = 40*5 Now to solve for x x*2 + (40-x)*7 = 40*5 x*2 + 7*40 - 7*x = 40*5 x*2 - 7*x = 40*5 - 7*40 -5*x = - 2*40 x = 2*8 x = 16 So we need 16 quarts of 2% milk and 40-16 = 24 quarts of 7%, which matches option "B".</span>

Write an equation that expresses the following relationship. p varies directly with d and inversely with the square root of u In

NARA [144]

<span>The equation given as p varies directly with d and inversely with the square root of u is written as:
</span>
p = k1d
k1 is the proportionality constant.
and p = k2 $\frac{1}{ \sqrt{u} }$
here k2 is the proportionality constant.

Thus,
combining both equations we get, p = C $\frac{d}{ \sqrt{u} }$
where K = K1*K2, K is the proportionality constant.
