Step-by-step explanation:

Factor the numerator and denominators and cancel the common factors.

Answer:

y=5/4x+8 Answer Choice D).

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(18-13)/(8-4)

m=5/4

y-y1=m(x-x1)

y-13=5/4(x-4)

y-13=5/4x-20/4

y-13=5/4x-5

y=5/4x-5+13

y=5/4x+8

Answer:

The statue is 22ft tall.

Step-by-step explanation:

Here we will have two similar triangle rectangles.

One is made between the girl's feet, the mirror, and the girl's eyes.

So in this case the catheti are:

the distance between the girl and the mirror (3 m) and the height of the girl (5.5 ft)

The other triangle rectangle has the vertices:

The mirror, the base of the statue, and the top of the statue.

Such that the catheti of this triangle are the distance between the base of the statue and the mirror (12m) and the height of the statue (we want to know this, let's call this X for the moment).

Because the triangles are similar, this means that there is a proportionality constant between each correspondent side, let's call this k.

Then the distance between the girl and the mirror must be k times the distance between the base of the statue and the mirror:

3m = k*12m

And the height of the girl must be k times the height of the statue.

5.5ft = k*X

You can see that we have different units, this does not matter because k is a dimensionless constant.

With the first equation we can find the value of k

3m = k*12m

3m/12m = k

(3/12) = 1/4 = k

Now we can replace this in the other equation to get:

5.5ft = (1/4)*X

Solving this for X we get:

(5.5ft)*4 = X

22ft = X

The height of the statue is 22ft.

Step-by-step explanation:

Using the trigonometric identity

2sinxcosy = sin(x + y) + sin(x - y) , then

with x = 70 and y = 20

2sin70cos20

= sin(70 + 20) + sin(70 - 20)

= sin90 + sin50

= right side , thus proven

Answer:

V = 768in³

LA = 608in²

SA = 692in²

Step-by-step explanation:

Volume:

7 x 12 ÷ 2 = 42

42 x 19 = 768

LA:

11 x 19 = 209

9 x 19 = 171

19 x 12 = 228

209 + 171 + 228 = 608

SA:

12 x 7 = 84

84 + 608 = 692

hope this is right:)

Answer:

~27.764982043070833894247682407876

Step-by-step explanation:

First, we can add 8+5.5+8 because of the two sides which are 8 and one that is 5.5. That is 21.5.

Then, we must find the diagonal edge. To do that, we can use the pythagorean theorem. It makes a triangle, so given that a^2+b^2=c^c, we can say that 3^2+5.5^2=c^c. Using a calculator, we can find the square root of 39.25, then add it to 21.5.

Answer:

Median is used to describe the center of the data of heights of 50 basketball players.

Step-by-step explanation:

The median divides the data into two equal parts.

It can be used to describe the center of the data.

The mean gives the average where most data lies.

The advantages of median are

1)it is located even when the values are not capable of quantitative measurements.

2) It is not affected by extreme values > It can be computed even when a frequency distribution  involves open end classes like those of income and prices.

3) In a highly skewed distribution median is appropriate average to use.

The disadvantages of the mean are

1) it is greatly affected by extreme values.

2) It sometimes gives fallacious conclusions.

3) In a highly skewed distribution mean is  not an appropriate average to use.

4) It cannot be computed even when a frequency distribution  involves open end classes like those of income and prices.

Answer:

4²+b² = 5²

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem to find the length of the missing side.

The Pythagorean theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse.  Algebraically, this is represented as

a²+b² = c²

We have the measure of one leg, 4 in.  We also have the measure of the hypotenuse, 5 in.  This gives us

4²+b² = 5²

Answer:300

Step-by-step explanation:

Answer:

17.5m

Step-by-step explanation:

We solve using the formula

Height /Shadow

Height of flag staff = 7m

Shadow of flag staff = 8.2 m

Height of the building = x

Shadow of the building = 20.5

= 7/8.2 = x/20.5

Cross Multiply

8.2x = 7 × 20.5

x = 7 × 20.5/8.2

x = 143.5 / 8.2

x = 17.5m

The height of the building is 17.5 m

Step-by-step explanation:

Ok lets find 20% of 35 first.

20% of 35 is just 2 lots of 10%

10% of 35 is 3.5 if we move over the decimal

2 lots of 3.5 is 7

add the tip on

35 + 7 = 42

42 / 2 = 21

They each get $21

good luck mate!

Step-by-step explanation:

Answer:

30.25 seconds

Step-by-step explanation:

If you want to find the time at which the wrench hits the ground, you must recognize that the height of the wrench is 0 feet. If h represents the height, then 0 can be plugged in for h. The equation is now 0=16x+484. You then must subtract 484 from both sides, giving you -484=16x. You then divide both sides by 16 to give you x by itself. -484/16=-30.25. Because this is dealing with time and negative time does not exist, the negative sign on the 30.25 can be neglected.
