Answer: 81

Step-by-step explanation: Divide the number of blue marbles by the number in the ratio of the number of blue marbles. 99/11=9. Then multiply that by 9 to get the number of red marbles. 9*9=81.

What is the solution to the equation 32x − 1 = 243? Question 18 options: A) x = 2 B) x = 3 C) x = 4 D) x = −2
Mama L [17]

Answer:

x = 4

Step-by-step explanation:

To solve this equation, first you want to write the whole thing out.

32x - 1 = 243

Next you want to get the variable by itself, so you are going to use inverse operations. in the equation, it is 32x - 1, so you are going to add one to both sides, getting you this:

32x = 244

Now for the final step you are going to get x alone, so you are going to use inverse operations once more and divide 32 on both sides getting you your answer.

x = 4

Now if you want to check your work simply plug in x, and if it is equal, you got the correct answer!

I hope this helped and good luck with your math!

I'm really sorry if I'm wrong though, even though I already finished this unit a while ago I struggled on this one even though it is so easy compared to the equations I have now.

Using the volume of the spherical balloon, it is found that it will take 24 hours for the balloon to become completely empty.

<h3>What is the volume of a sphere?</h3>

The volume of a sphere of radius r is given by:

V = \frac{4\pi r^3}{3}

Aspherical balloon has a radius of 6 feet, hence the volume is:

V = \frac{4\pi 6^3}{3} = 905

It has already lost 20% of it's air, and air is leaking out of the balloon at a rate of 30 cubic feet per minute, hence the volume after t minutes is given by:

V(t) = 0.8(905) - 30t

V(t) = 724 - 30t

It will be completely empty when:

V(t) = 0

724 - 30t = 0

30t = 724

t = \frac{724}{30}

t = 24.1

Rounding, it will take 24 hours for the balloon to become completely empty.
