The number line shows the change in temperature from 7:00 a.M. To 1:00 p.M. Which expression shows how to find the difference be
xz_007 [3.2K]

Answer:

B

Step-by-step explanation:

The options in the question and the number line are shown in the image attached.

From the options, it is clear that the difference between the temperatures at 7:00 a.M. and 1:00 p.M is;

Temperature at 7:00 a.M - Temperature at 1:00 p.M

We can see from the number line that the temperature at 7:00 a.M = -4

Temperature at 1:00 p.M = 16

difference between the two temperatures = ∣(-4) - 16∣ = 20

<span>(A) Find the approximate length of the plank. Round to the nearest tenth of a foot.
Given that the distance of the ground is 3ft.
In order to get the length of the plank,
we can use the this one.

cos 49 = ground / plank
cos 49 = 3 / plank
plank = cos 49 / 3
plank = 0.10 ft

</span><span>(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.
</span><span>
The remaining angle is equal to
angle = 180 - (90+49)
angle = 41

Finding the height.
tan 41 = height / ground
tan 41 = height / 3
height = tan 41 / 3
height = 0.05 ft.

(A) 0.10 feet
(B) 0.05 feet</span>
