When Marla rounded 19.95 to the nearest tenth she found the number change to 20 is this correct. Explain

1 answer:

Yes, because a number that is 5 or higher, rounds up. so the five would make the 9 round up, which would make the 19 go to a 20

A subway train is traveling at a rate of 22.4 m/s. Brakes are applied and it slows down at a constant rate of 3.5 m/s2 until it

WARRIOR [948]

You use the equation Final Velocity²= (Initial Velocity)² 2(Acceleration)(Distance). You plug in what you have 0²=22.4² X 2(-3.5)(D) and solve for D which is 71.68m or about 72m.

What is the area of d=8 and r=4

Alex

So, for the semi circle, we need to find the area of a circle then divide it by 2.

pi times r squared

$\pi 16$ is the area of a circle with the radius of 4

(I'm going to use 3.14 as pi)

So 3.14 times 16 is 50.24

Divide that by 2 and we get 25.12

For the rectangle at the bottom. We know that the radius is four, so we can cut off 4ft from the height, leaving us with 8.

8 times 8 is 64.

To find the area of the whole figure, we add 64 and 25.12 together, getting 89.12

So the area is 89.12 feet squared.

Any questions?
