I need help on this one question I am stuck on it.

lutik1710 [3]

Given:

8.90ft³ for 30 balloons

Let h be the volume of helium and b be the number of balloons.

Using proportion;

b/h = 30 /8.90

Multiply both-side by h

$\frac{b}{h}\times h=\frac{30}{8.90}\times h$ $b=\frac{30}{8.90}h$

Hence, the answer to blank 1 is the above.

when b=50, substitute for b in the above and solve for the volume (h).

That is;

$50=\frac{30}{8.90}h$

Multiply both-side by 8.90/30

$50\times\frac{8.90}{30}=h$

$14.83=h$

Hence, the answer to blank 2 is 14.83ft³.

A bag contains five red marbles, four blue marbles, and three yellow marbles. You randomly pick a marble. What is the probabilit

Serga [27]

Answer and Step-by-step explanation:

First, find the total amount of marbles.

5 + 4 + 3 = 12

There are 12 marbles in total.

The probability of picking a red or blue marble would be 9 out of 12, since it is asking for either the red marble or the blue marble.

9/12 is the answer. (Simplifies down to 3/4)
