Does anyone know the answer???

Hello!

Just to make this simpler, let's convert the fractions to decimals.

-3.5-(-12.25)

-- means add, so we will switch it to that.

-3.5+12.25

Now we add.

-3.5+12.25=8.75

.75 is 3.4.

Therefore, our answer is D) 8 3/4.

I hope this helps!

What is the average acceleration of a southbound train that slows down from 15 m/s to 8.6 m/s in 1.2 s?

horrorfan [7]

Answer:

The average acceleration of train is $5.34\ m/s^2$

Step-by-step explanation:

We have,

A train that slows down from 15 m/s to 8.6 m/s in 1.2 s. It means that 15 m/s is its initial velocity and 8.6 m/s is its final velocity.

It is required to find the average acceleration of the train.

$a=\dfrac{v-u}{t}\\\\a=\dfrac{(8.6-15)\ m/s}{1.2\ s}\\\\a=-5.34\ m/s^2$

The average acceleration of train is $5.34\ m/s^2$ . Negative signs shows that the train is decelerating.

Round 89,891 to the nearest ten-thousands place.

frez [133]

The ten thousands digit is the 8 to the left edge.

You need to increase this digit because the thousands digit is greater than zero.

The answer is 90,000.
