A driveway is 90 feet long, 15 feet wide, and 4 feet deep. How many cubic feet of concrete will be required to fill the driveway?Group of answer choices

546 ft

2555 ft

5,400 ft

540 ft

Answers

Answer 1
Answer: To find the volume of the driveway, we need to multiply its length, width, and depth.

The length of the driveway is 90 feet, the width is 15 feet, and the depth is 4 feet.

Volume = length x width x depth

Volume = 90 ft x 15 ft x 4 ft

Volume = 5400 cubic feet

Therefore, 5400 cubic feet of concrete will be required to fill the driveway.

Hence, the correct answer is 5400 ft³.

Given g ( x ) = 3 x − 4 g(x)=3x−4, solve for x x when g ( x ) = 5 g(x)=5.

Answers

Answer:

g(5) = -19

Step-by-step explanation:

Substitute 5 for x in the equation

Plug in 5 for the x's and get g(x)=-3(5)-4 and then -15-4 which is -19 so g(x)=-19

In the question "Marta’s mother shared a funny video of their cat on the Internet. The total number of people who had viewed the video over the first 30 days could be modeled using the function f(x) = 33(1.3)x where x is the number of days the video has been online. About how many people had viewed the video once it had been online for 20 days?" The correct answer is 6271 because given the function f(x) = 33(1.3)^x where x is the number of days the video has been online. For x = 20 days: f(20) = 33(1.3)^20 = 33(190.0496377) = 6,271

By evaluating the exponential equation we will see that the correct option is 6,271.

How many people viewed the video after 20 days?

We know that the number of people that view the video is given by:

f(x) = 33*(1.3)^x

Where x is the number of days.

Then, we just need to evaluate the function in x = 20, we will get:

f(20) = 33*(1.3)^(20) = 6,271

So we conclude that after 20 days, 6,271 people saw the video.
