I would say the correct answer is D.

It corresponds with the statement made in the question, saying that 95%(the majority) of customers who rated the store as having high quality service returned.

Well to find the slope you go y1-y2/x1-x2
In this case you have 9/-17 now the y intercept is when x is 0 what is why which is 4

Your answer is y=-9/17x+4

The perpendicular bisectors of sides AC and BC of △ABC intersect side AB

tiny-mole [99]

The measure of ∠ACB will be 110°

Explanation

According to the diagram below, $DE$ and $DF$ are the perpendicular bisectors of $AC$ and $BC$ respectively and they intersect side $AB$ at points $P$ and $Q$ respectively.

So, $AE=CE$ and $CF= BF$

Now, according to the $SAS$ postulate, ΔAPE and ΔCPE are congruent each other. Also, ΔCFQ and ΔBFQ are congruent to each other.

That means, ∠PCE = ∠PAE and ∠FCQ = ∠FBQ

As ∠CPQ = 78° , so ∠PCE + ∠PAE = 78° or, ∠PCE = $\frac{78}{2}= 39$ ° and as ∠CQP = 62° , so ∠FCQ + ∠FBQ = 62° or, ∠FCQ = $\frac{62}{2}=31$ °

Now, in triangle CPQ, ∠PCQ = 180°-(78° + 62°) = 180° - 140° = 40°

Thus, ∠ACB = ∠PCE + ∠PCQ + ∠FCQ = 39° + 40° + 31° = 110°

Carrie borrowed $800 dollars from her aunt at 8% interest per year. If she paid her a total of $448 in simple interest, how many

Jet001 [13]

Answer:

13 years

Step-by-step explanation:

First we will have to see how much she owns her aunt:

800-448= 362

8% of 348 = 27.84

362 ÷ 27.84 = 13 years

I might be wrong but hopefully this helps :)

Answer:

$(\pi 4^2 (9))-(\pi 2^2 (9))$

and

$339.292 cm^3$

Step-by-step explanation:

This question is simple once you break it down.

Let's concentrate on the outer cylinder.

First, find the volume of the outer cylinder.

The volume of a cylinder is expressed as: $V = \pi r^2 h$

Gathering information from the diagram..

d = 8 cm

h = 9 cm

You can get the radius from the diameter by just dividing the diameter by 2.

$r = \frac{8}{2}=4$

r = 4

Plug everything into the volume equation.

$V = \pi 4^2 (9)$

Don't solve just yet!

Now, find the volume of the inner cylinder.

Do the exact same thing as you did for the outer cylinder.

d = 4 cm

h = 9 cm

$r = \frac{4}{2}=2$

r = 2

Plug everything into the volume equation..

$V = \pi 2^2 (9)$

The question asks for an expression to represent the volume of the large cylinder after the cylindrical hole is removed. This means you need to subtract the volume of the cylindrical hole from the volume for the large cylinder.

Again, the volume for the large cylinder is $V = \pi 4^2 (9)$ and the volume for the cylindrical hole is $V = \pi 2^2 (9)$

This means..

$(\pi 4^2 (9))-(\pi 2^2 (9))$

That is your answer to the first part of the question.

For the second part, just solve.

$(\pi 4^2 (9))-(\pi 2^2 (9))$

$(\pi*16*9)-(\pi*4*9)$
