Answer:

x=6

Step-by-step explanation:

we know that the area you are trying to solve for has to be equal to 90 degrees. so you would add the two equations together 5x and (x+54).

STEP ONE

combine like terms and get 6x+54=90

STEP TWO

move get 6x to the right hand side and change the sign, 6x=90-54

STEP THREE

subtract the numbers, 6x=36

STEP FOUR

divide both sides of the equation by 6, x=6

What is the 23rd term in the arithmetic sequence 11,14,17,20?
nikdorinn [45]
To find the next term in an arithmetic sequence, your best bet would be to use the formula N(x)= N(1) + (x-1)*d, where x stands for the term you want to find, N(1) stands for the first number in the sequence, and d stands for the common difference between the numbers.

First, lets see what we can plug in. We know the first term in the sequence (N(1)) is 11, we know that we want to find the 23rd number in the sequence (x), and by subtracting the 2nd term by the 1st term (14-11), the common difference (d) is 3. When we plug that all into our equation, it should end up looking something like this: N(23)= 11 + (23-1)*3.

Next, we can break down the equation to solve it step by step using PEMDAS. Parenthesis go first, so N(23)= 11 + (23-1)*3 becomes N(23)= 11 + (22)*3. We don't have any exponents, so we can skip the E. Next, we do multiplication and division from left to right, so N(23)= 11 + (22)*3 becomes N(23)= 11 + 66. Finally, we do addition and subtraction from left to right, getting us from N(23)= 11 + 66 to N(23)= 77, which means that the 23rd number in the sequence is 77!

Find the EXACT circumference if the area is 196π square feet. Unit of measurement is feet or ft
Elena-2011 [213]

Answer:

87.9645943005 feet

Step-by-step explanation:

The formula for the area of a circle is pi x radius to the power of 2. What number to the power of 2 is 196? 14.

So, the radius is 14.

The formula for the circumference of a circle is pi x diameter. If the radius is 14, the diameter is 28.

28 x pi = 87.9645943005

A certain animated movie earned $1.1*10^9 in revenues at the box office. The movie lasts 9.1*10^1 minutes. How much revenue was
Vadim26 [7]

Answer:

$12,087,912.1

Step-by-step explanation:

1.1*10^9  is in scientific notation, to get this into normal number, we take the decimal point and move it "9" times to the right [whatever power of 10 we have, we move to right (if positive).] Then we fillup the rest with zeros.

So we have:

1.1*10^9=1,100,000,000

This is the revenue.

We do similar process for time:

9.1*10^1=91

This is the time , in minutes.

We want revenue PER minute, that means we divide the total revenue by total time, that would be:

\frac{1,100,000,000}{91}=12,087,912.1

The revenue earned per minute is  $12,087,912.1
