The arc length of a sector created by a 90° angle is 25 cm. What is the circumference of the entire circle? Express
the answer in terms of Pi

Answers

Answer 1

Answer:

We know length of one quarter of a circle = 2πr/4 = πr/2

So here we can make the equation for to find thr value of radius r

length of one quarter given = 25 cm

so πr/2 = 25 cm

=> πr = 50 cm

=> r = 50/π cm

So the entire circumference of circle =

2πr

= 2 π 50/π cm

= 100π/π cm (ans)

Here we dont substitute the value of π due to represent the answer in terms of pi.

Hope it helps you

Answer:

She should add 10x to both sides

Step-by-step explanation:

Answer:

Step-by-step explanation:

x² - 10x - 2 = 0   {Add 2 to both sides}

            +2 = +2

x² - 10x     = 2

Now to find what to add both sides, divide the co-efficient of x by 2

10/2 = 5

Add 5² to both sides

x² - 10x + 25 = 5²

(x - 5)² = 5²

Take square root both sides,

x - 5 = ± 5

x- 5 = 5   ;   x - 5 = -5

  x = 5+5 ;      x = -5 + 5

  x = 10    ;      x = 0

The lowest point in a business cycle, which follows a period of economic
decline, is called a(n)
A. trough
B. contraction
C. peak
D. expansion

Answers

Your answer is b hope this helps

The lowest point in a business cycle, which follows a period of economic

decline, is called a trough. Therefore, option A is the correct answer.

What is a period of economic decline?

A prolonged period of weak or negative real GDP (output) growth that is accompanied by a noticeably higher unemployment rate is known as a recession. During a recession, a lot of other economic activity indices are similarly weak.

Trough: This refers to the stage of the business cycle when economic activity is at its lowest point.

Expansion: It denotes the period following a dip when overall demand rises. It leads to a rise in output and a decrease in unemployment.

In the business cycle, expansions and contractions alternate (also called recessions).

Recessions frequently begin at the business cycle's high, when an expansion comes to an end, and finish at its trough, when the following expansion starts.

Therefore, option A is the correct answer.

x = 5 [tex]\frac{2}{5}[/tex]

Step-by-step explanation:

Hi there!

So, to answer this problem, I'll use the reverse method.

31 - 4 = 27,

So how many times, can 5 go into 27?

The closest factor of 5 to 27 is 25.

5 can go in to 27,  5 times.

Continuing on, there is a 2 left over, so the answer to your question is

x = 5 [tex]\frac{2}{5}[/tex]

5 · 5 [tex]\frac{2}{5}[/tex] - 4 = 31

A cylindrical fuel storage tank has a diameter of 19 feet. Determine the capacity of the tank, if its height is 34 feet. (use = 3.14)​

Answers

Answer:

The tank capacity is 9,635.09 square feet.

Step-by-step explanation:

Given that a cylindrical fuel storage tank has a diameter of 19 feet and a height of 34 feet, the following calculation must be performed to determine the capacity of the tank, knowing that the volume of a cylinder arises from the following formula = π x r² xh:

Radius = 1/2 diameter

3.14 x (19/2) ² x 34 = X

3.14 x 9.5² x 34 = X

3.14 x 90.25 x 34 = X

3.14 x 3,068.5 = X

9,635.09 = X

Therefore, the tank capacity is 9,635.09 square feet.

A TV has a listed price of $671.98 before tax. If the sales tax rate is 7.5%, find the total cost of the TV with sales tax included.
Round your answer to the nearest cent, as necessary.

Answers

Answer:

The price of the TV with the sales tax included is $ 722.38.

Step-by-step explanation:

Given that a TV has a listed price of $ 671.98 before tax, and the sales tax rate is 7.5%, to find the total cost of the TV with sales tax included the following calculation must be performed:

671.98 + (671.98 x 0.075) = X

671.98 + 50.3985 = X

722.3785 = X

Therefore, the price of the TV with the sales tax included is $ 722.38.

x = 19

Step-by-step explanation:

The 5x + 30 should also = 125, since they both have the same angle.

So you can make this equation:

125 = 5x + 30

125 - 30 = 5x

95/5 = x

x = 19

Step-by-step explanation:

125°=5x+30°

125-30= 95

95÷5=19

so x = 19
