The scatter plot shows the amount of sunlight some tomato plants received and the amount of each plant grew

Studentka2010 [4]

Answer:

Option D

Step-by-step explanation:

The complete question is attached herewith.

Also the options for the same are as follows -

What is the meaning of the slope of the trend line shown on the scatterplot?

A A plant grows about 3 inches for every 2 hours of sunlight it receives.

B A plant grows about 2 inches for every 3 hours of sunlight it receives.

C A plant grows about 3 inches for every 1 hour of sunlight it receives.

D A plant grows about 1 inch for every 3 hours of sunlight it receives.

Solution

If we look at the graph, we can see that in 6 hours the tomato plant grew by 2 inches.

At the X axis, when x = 6 hours, the y co-ordinate at X = 6 hours is 2 inches.

Hence, It can be interpreted that 1 inch of the tomato plant grows in 3 hours.

Hence, option D is correct

If a car has traveled 171 miles in 3 hours at a steady pace, how far has it traveled each hour?

san4es73 [151]

Answer:

B: 57 mph=57 mph

Step-by-step explanation:

A steady pace means constant speed that it does not change over a period of time and direction of motion. A simple formula, for this case (constant speed)

$v= \frac{x - xo}{t -to}$

where x is distance and t time. The subtract is final value minus initial value

We have the distance and time, then

$v= \frac{171 miles}{3 hours} = 57 mph$

Two angles are supplementary. The measure of one angle is 4 times the measure of the other angle. What is the measure of the sma

Alexus [3.1K]

ANSWER

The smaller angle is

$y = 36 \degree$

.EXPLANATION

Let the angles be
$x \: and \: \: y$

where y is the smaller angle.
Since they are supplementary, they will add up to 180°.

This implies that,

$x + y = 180 \degree...(1)$

If one angle is 4 times the other, we can then write the following equation,

$x = 4y...(2)$

We put equation (2) into equation (1) to get,

$4y + y = 180 \degree$

$5y = 180 \degree$

We divide through by 5 to obtain,

$y = 36 \degree$

This implies that,

$x = 4(36)$

$x = 144 \degree$
