Answer:

D

Step-by-step explanation:

Because 150 times 4 = 600.

It’s D


EXPLAIN:
Graph D starts at Zero and shows that after a min it is at about 150. ( which is what you want) also if you add 150 then you go over one min.
So 150•4= 600 which is seen on the graph.

Where as
A is wrong because it takes 8 min to reach 150
B is wrong because it starts at 50 and it takes 6 min to fuel an additional 150
C is wrong because it takes 4 to add an addition 150.

What is the slope of a line perpendicular to the line whose equation is 2x+8y -64 Fully reduce your answer.
Lelechka [254]

Answer: I am pretty sure it is y=-1/4x-8. Hope this helps!

Step-by-step explanation:subtract the 2x from both sides which gives you 8y=-2x-64. Then you want to divide both sides by 8 to get y=-1/4x-8

if Amanda hikes at an average speed of 2.72 miles per hour, how long will it take her to hike 6.8 miles
kompoz [17]
Speed times time=distance
distance=6.8
speed=2.72
time=?

2.72 times ?=6.8
divide both sides by 2.72
?=2.5

answer si 2.5 hours

The ratio of the lengths of corresponding parts in two similar solids is 5:1,
vlabodo [156]
The ratio of the surface areas of two similar solids can be computed by squaring the given ratio of the corresponding sides. For this given,
                                r = (5:1)^1
                               r = 25:1

Thus, the ratio of the surface areas of the similar solids is 25:1.

Lionel computed the average rate of change in the depth of a pool over a two-week interval to be zero. Which statement must be t
gayaneshka [121]

Answer:The pool must have been the same depth at the start of the interval as it was at the end of the interval.

Step-by-step explanation:

The average rate of change is calculated as:

[final value - initial value] / time interval.

Then, the average rate of change does not take into account intermediates values, and you cannot draw any conclusion about such intermediate values.

In the given case you have:

average rate of change in depth = [final depth - initial depth] / 2 weeks.

0 = [final depth - initial depth] / 2 weeks.

⇒ 0 = final depth - initial depth

⇒ final depth = initial depth.

That is why the conclusion is the second statement of the answer choices: the pool must have been the same depth at the start of the interval as it was at the end of the interval.

In between the pool might have been deeper, more shallow, empty or change in any form, since the average rate of change does not tell the full history but only the net change.

In a right triangle ΔABC, the length of leg AC = 5 ft and the hypotenuse AB = 13 ft. Find: Chapter Reference b The length of the
Butoxors [25]

Answer:

The length of the angle bisector of angle ∠A is 6.01.

Step-by-step explanation:

It is given that length of leg AC = 5 ft and the hypotenuse AB = 13 ft.

Using pythagoras theorem

(AB)^2=(BC)^2+(AC)^2

(13)^2=(BC)^2+(5)^2

169=(BC)^2+25

BC=12

\sin A=\frac{\text{perpendicular}}{\text{hypotenuse}}

\sin A=\frac{BC}{AB}

A=\sin ^{-1}\frac{12}{13}

A=67.38

Bisector divides the angle in two equal parts, therefore,

A'=\frac{67.38}{2} =33.69

In triangle ACD.

\cos A'=\frac{\text{Base}}{\text{Hypotenuse}}

\cos A'=\frac{AC}{AD}

\cos (33.69^{\circ})=\frac{5}{AD}

0.832=\frac{5}{AD}

AD=\frac{5}{0.832} =6.009\approx 6.01

Therefore the length of the angle bisector of angle ∠A is 6.01.
