Note that  the scale factor of B to A  is  (4 / 8)  =  1/2

So....the volume of B  =

Volume of A  *  (scale factor)^3  =

2720  *  (1/2)^3  =

2. A student usually saves $20 per month. He would like to reach a goal of saving $350 in 12 months. The student writes the equa
Zigmanuir [339]

Answer:

x = 9.17 (nearest hundredth)

The variable x is the amount the student needs to save each month in addition to his usual saved amount of $20.

Step-by-step explanation:

350 = 12(x + 20)

Multiply out brackets:  350 = 12x + 240

Subtract 240 from both sides:  110 = 12x

Divide both sides by 12:  9 1/6 = x

x = 9.17 (nearest hundredth)

The variable x is the amount the student needs to save each month in addition to his usual saved amount of $20.

Find two positive numbers whose product is 25 and whose sum is a minimum. (if both values are the same number, enter it into bot
pshichka [43]
Let xy = 25, x and y > 0.

y = \frac{25}{x}
\text{Denote S as: } x + y
S(x) = x + \frac{25}{x}

\text{Minimum: }S'(x) = 0, S''(x) > 0
S'(x) = 1 - \frac{25}{x^{2}}
1 - \frac{25}{x^{2}} = 0
x^{2} = 25
x = 5 (x > 0)

S''(x) = \frac{50}{x^{3}} > 0, (x > 0)

Thus, at x = 5, there lies a minimum summation, and this forms a square with side length of 5.
