Stefan sells Jin a bicycle for $138 and a helmet for $18. The total cost for Jin is 130% of what
lys-0071 [83]

Answer:

1. $109.20 2. $46.80

Step-by-step explanation:

Doing the math, we find that 30% of 156 (138+18) is 46.80, which answers the second part of this problem. Plugging this value into the first part of the equation gives us what Stefan originally paid.

Good luck! Hope this helps!

A round balloon has a diameter of 7 inches
gizmo_the_mogwai [7]

Answer:

The right answer is approximately 210.031 cubic inches. (Answer: E)

Step-by-step explanation:

First, we need to convert the diameter (D), in inches, of the round balloon to an entirely decimal mode:

D = 7\,in + \frac{3}{8}\,in

D = \frac{56 + 3}{8}\,in

D = \frac{59}{8}\,in

D \approx 7.375\,in

The volume of the balloon is modelled after the volume function of a sphere (V), in cubic inches:

V = \frac{\pi}{6}\cdot D^{3} (1)

If we know that D \approx 7.375\,in, then the volume of the round balloon is:

V = \frac{\pi}{6}\cdot D^{3}

V = \frac{\pi}{6} \cdot (7.375\,in)^{3}

V \approx 210.031\,in^{3}

Hence, the right answer is approximately 210.031 cubic inches.
