Answer:

The acceleration of the train is 0.5m/s²

Step-by-step explanation:

Given

Velocity of the train = 10m/s

Time taken = 20 s

Required

Find the acceleration of the train.

The Acceleration if an object is the rate of change of the velocity of the object over time.

In other words, acceleration is calculated by dividing velocity by time.

Mathematically,

Acceleration = velocity ÷ Time

By substituting 10m/s for velocity and 20s for time, we have

Acceleration = 10m/s ÷ 20s

Acceleration = 10/20 m/s²

Acceleration = ½m/s²

Acceleration = 0.5m/s²

Hence, the acceleration of the train is 0.5m/s²

A coordinate plane with the x-axis labeled Blueberries (in pints) and the y-axis labeled Cost (in dollars) shows a line going through (0, 0) and (5, 17).

<h3>What is directly proportional?</h3>

It is defined as the relationship between two quantities as one quantity increases the other quantity also increases and vice versa.

It is given that there is a proportional relationship between cost and pints of blueberries as,

Blueberries (in pints)          2      5

Cost (in dollars)                6.80   17

17/6.80 = 5/2

As we draw the graph and analyze each option one by one we get the graph shown by the statement C following the given proportional relationship.

Thus, a coordinate plane with the x-axis labeled Blueberries (in pints) and the y-axis labeled Cost (in dollars) shows a line going through (0, 0) and (5, 17).

What is the volume of a block of ice measuring 3 meters long, 1.5 meters wide, and 2 meters high? A. 900 cu. m B. 12 cu. m C. 9
lutik1710 [3]
To find volume of a rectangular prism, you simply need to multiply length times width times height. We know from the text that our block of ice is 3 meters long, 1.5 meters wide, and 2 meters high. So all we need to do is multiply:

3 * 1.5 = 4.5

4.5 * 2 = 9

The block of ice has a volume of 9 cubic meters.
Choice C is your correct answer.
Hope that helped! =)
