13 because 13*4=52. So 13 is the only one that goes into each one.

a 12-ft ladder leans against a building so that the angle between the ground and the ladder is 74°. how high does the ladder rea

WINSTONCH [101]

Answer:

12 feet

Step-by-step explanation:

Sometimes, a simple drawing is a great way to start! In the attached drawing, the red line represents the ladder, the brown represents the ground, and the black represents the building!

We want to find the side of the triangle from where the ladder meets the building to where the building meets the ground. This can be found using trigonometric identities, namely sine:

$sin\theta=\frac{opposite}{hypotenuse}$

Plug in known values:

$sin(74^o)=\frac{x}{12}$

Rearrange to isolate the variable:

$x=12sin(74^o)$

Simplify!

$x=11.535140... ft$

Round to the nearest foot:

$x=12ft$

If 12% = 1000, what is the remaining 88% worth?

MrRissso [65]

Note: I am not 100% sure that this is the correct way to solve this problem. It is just my best attempt to help.

Keep in mind that every percentage can be made into a decimal. 12% = 0.12 because 12% is also 12/100 as a fraction.

Since a percentage is the original number multiplied by the percent, you can solve this problem by dividing the number given by the percent. Be sure to turn the percent into a decimal to make it easier. Your work should look like this:

12% = 0.12

1,000 / 0.12 = 8,333.33

That is the first step. How you have to finish the problem and find what 88% is. To do this, you can simply multiply 88%, or 0.88, times the answer you get in the first part. Your work should look like this:

88% = 0.88
0.88 * 8,333.33 = 7,333.33

Now to check your work, you can add 7,333.33 and 1,000 to see if it equal the total of 8,333.33

7,333.33 + 1,000 = 8,333.3

Since it is equal, this is your answer.

What is the strongest classification of the figure formed by the following points?

tatiyna

Answer:

A. Parallelogram

Step-by-step explanation:

The given points are;

(-10, -4), (-7, -8), (-5, -4), (-2, -8)

Let 'A' represent the point (-10, -4), let 'B' represent the point (-7, -8), let 'C' represent the point (-5, -4), and let 'D' represent the point (-2, -8), we have;

The (horizontal) distance between points A and C = -5 - (-10) = 5

The (horizontal) distance between points B and D = -2 - (-7) = 5

Therefore;

The length of $\overline {AC}$ = The length of $\overline {BD}$
