Answer:

ex.: 71 (see explanation)

Step-by-step explanation:

The answers on this could vary. An acute angle is an angle less than 90 degrees. However, you also have to remember that a triangle adds up to 180 degrees, so the angle cannot be so small that the third angle would be over 90. For my answer, I subtracted 38 from 180 (the whole triangle) and then divided by 2.

I hope this helps.

For each problem, explain or show your reasoning, a. 160 is what percentage of 40? b. 40 is 160% of what number? c. What number

Answer:

A. 160 Out of 40 is 400%./// B. The answer is 25/// C. The answer is 3905%

Step-by-step explanation:

( A ) One step solution:

You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.

So, 160 is 40% of = 160 X 100 = 400

( B ) The same thing as A but the numbers are switched

One step solution:

You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.

So, 40 is 160% of = 40 × 100 = 25

160

( C ) Working out a percentage increase or decrease between two numbers is pretty simple. The resulting number (the second input) is 1602 and what we need to do first is subtract the old number, 40, from it:

1602 - 40 = 1562

Once we've done that we need to divide the result, 1562, by the original number, 40. We do this because we need to compare the difference between the new number and the original:

1562 = 39.05

We now have our answer in decimal format. How do we get this into percentage format? Multiply 39.05 by 100?

39.05 x 100 = 3905%

I know the answer is right but it said it’s wrong. Can I get a second answer to make sure? Thank you so much!

Answer:

70.3 ft

Step-by-step explanation:

The ratio of the adjacent side (33 or KM) to the hypotenuse (X or KL) is the cosine of the angle:

cos(62°) = 33/KL

Multiplying by KL/cos(62°) gives ...

KL = 33/cos(62°) ≈ 33/0.4694 ≈ 70.292 ≈ 70.3

The length of KL is about 70.3 feet.

Given that (12,3) is on the graph of f(x), find the corresponding point for the function 8f(x)

Paha777 [63]

When the function is multiplied by a number, in this case f(x) is being multiplied by 8, the outcome of the function is multiplied by 8. So, if you were to still input 12 as x, you would get an output that is 8 times the original. 3 • 8 = 24. The new point would be (12, 24).
