Answer:

623, 529

Step-by-step explanation:

Let's rewrite the problem: 6.8% of what number is 42,400?

Represent the problem as an equation.

0.068 * n = 42,400 (6.8% = 0.068)

0.068/0.068 = 0

42,400/0.068 = 623,529.4117647059

Round this value to the nearest whole number to receive: 623, 529

Answer:

617647

Step-by-step explanation:

6.8% = 42 400

Divide 42 400 by 6.8 to get 1%

1% = 6176.47058823529....

Multiply this by 100 to get 100%

100% = 617647.0588

We can check it by doing 617647.0588 * 6.8% = 42 400

Nearest whole number= 617647

The average rate of change, of the function, between the intervals, x = 2 to x = 6 is: 180.

<h3>What is the Average Rate of Change of a Function?</h3>

Average rate of change = $\frac{f(b) - f(a)}{b - a}$ .

Given the function, $f(x)= 3^x + 25$ ,

The average rate of change using the intervals of, x = 2 to x = 6 would be solved as shown below:

a = 2

b = 6

f(a) = $f(2)= 3^2 + 25$ = 34

f(b) = $f(6)= 3^6 + 25$ = 754

Average rate of change = $\frac{754 - 34}{6 - 2} = \frac{720}{4}$

Average rate of change = 180

Therefore, the average rate of change, of the function, between the intervals, x = 2 to x = 6 is: 180.

15 more than three times a number is equal to 75<br> Also please do a step by step

Vlad [161]

Answer:

Step-by-step explanation:

3n+15=75

three times a number is 3n. +15 is 15 more.

3n+15=75 subtract 15 from both sides to get the 3n alone

3n=60 divide by 3 to get the n by itself

n=20

If two forces of 5 lb. and 8 lb. acting at the same point are equivalent to a single force of 10 lb. Find the angle between the

Alchen [17]

The force of 10 pounds is made up of the horizontal components of the 8 and 5 pound forces

8 cos 30 + 5 cos 52 = 10

so your answer is 30 degrees
