What is the area of this figure

Answers

Answer 1

Answer:

153.86

Step-by-step explanation:

Divide the diameter by 2 to find the radius

14/2=7

A=3.14([tex]7^{2}[/tex])

A=3.14(49)

A=153.86

Answer 2

Answer:

The answer is 153.86 I believe.

Step-by-step explanation:

The radius is half the diameter, so r = 7. You have to square the 7 which gives you 49. Then multiply the 49 by 3.14 for pi. The answer you get is 153.86

A camera store developed 2100 rolls of film in one month. Customers wanted double prints from 1500 of these rolls. What is the ratio of rolls with double prints to rolls developed?

2:7

2:5

5:7

7:5

Answers

Answer:

the answer is 5:7

Step-by-step explanation:

as a fraction, the ratio looks like this:

1500/2100

where 1500 is the number of rolls with double prints and 2100 is the amount of rolls developed.

if you simplify the fraction, you get 5/7.

5/7 is 5:7 written as a ratio in this problem.

Write the equation of the line that passes through (-3, -20) and (1,4).

Answers

Answer:

y=6x-2

Step-by-step explanation:

The equation of the line is y=mx+b

FINDING SLOPE: To find the slope of a given line use the equation [tex]\frac{y2-y1}{x2-x1}[/tex]

So x1=-3, y1=-20 and x2=1, y2=4

Plug those numbers into the equation: [tex]\frac{4-(-20)}{1-(-3)}[/tex] and we get the slope which is 6.

FINDING Y-INTERCEPT: Then we find the y intercept by plugging in our points (you can choose) I will use (1,4) and solve.

y=6x+b

4=6(1)+b

b=-2

I really need the answer asap please and thanksss

Answers

Answer:

Read left to right

Do parenthesis first

-4 ( 1 + 5) ^2

-4 (6) ^2

Then exponent

6^2 = 6 x 6 = 36

-4 x 36 = -144

Then divide

-144 / 6 = -24

Then the next parenthesis

(42+5) = 47

-24 - 47 = -71

Step-by-step explanation:

Answer = -71
Step: -4(1+5)^2/6 -(42+5)

=-4(6^2)/6 -(42+5)

=( -4) (36)/6 -(42+5)

=-144/6 -(42+5)

= -24-(42+5)

= -24-47

= -71

The sum of the digits of a two-digit number is 8. The difference between the number and the reversed number is 10 more than the reversed number. Find the number.

Answers

Answer:

The number is 62

Step-by-step explanation:

Let the digits of the number be T and U;

A 2 digit number is represented as: 10T + U

So,

[tex]T + U = 8[/tex]

[tex]10T + U - (10U + T) = 10 + 10U + T[/tex]

Required

Find the digit

Make U the subject in the first equation

[tex]U = 8 - T[/tex]

Substitute 8 - T for U in the second

[tex]10T + U - (10U + T) = 10 + 10U + T[/tex]

[tex]10T + 8 - T - (10*(8-T) + T) = 10 + 10(8 - T) + T[/tex]

[tex]10T + 8 - T - (80-10T + T) = 10 + 80 - 10T+ T[/tex]

[tex]10T + 8 - T -80+10T - T = 10 + 80 - 10T+ T[/tex]

Collect Like Terms

[tex]10T + 10T - T- T + 8 -80 = 10 + 80 - 10T+ T[/tex]

[tex]18T -72 = 90 - 9T[/tex]

[tex]9T + 18T = 90 + 72[/tex]

[tex]27T = 162[/tex]

[tex]T = 162/27[/tex]

[tex]T = 6[/tex]

Recall that:

[tex]U = 8 - T[/tex]

[tex]U = 8 - 6[/tex]

[tex]U = 2[/tex]

Hence, the number is 62

A sinking fund is established to discharge a debt of $20,000 in 15 years. If deposits are made at the end of each 6-month period and interest is paid at the rate of 5%, compounded semiannually, what is the amount of each deposit? (Round your answer to the nearest cent.)

Answers

Answer:

the amount of each deposit is $45,555

Step-by-step explanation:

The computation of the each deposit is shown below:

Given that

Future value be $20,000

Time period = 15 × 2 = 30

And, the rate = 5% ÷ 2 = 2.5%

Now the formula is as follows

= (Future value × rate of interest) ÷ (1 + rate of interest)^time period - 1

= ($20,000 × 2.5) ÷ (1 + 0.025)^30 - 1

= $50,000 ÷ 1.0975675791

= $45,555

Hence, the amount of each deposit is $45,555

Rita goes for a bike ride on a trail by her house. After 15 minutes of riding she sees a mile marker. When she reaches the third mile marker, she realizes that she has been biking for 30 minutes. What is the rate at which she is riding?

Answers

Given:

Rita covered 1 mile in 15 minutes.

She covered 3 miles in 30 minutes.

To find:

The rate at which she is riding.

Solution:

Let y be the number of miles covered in x minutes.

Rita covered 1 mile in 15 minutes. So, the point is (15,1).

She covered 3 miles in 30 minutes. So, the point is (30,3).

Slope of the line:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{3-1}{30-15}[/tex]

[tex]m=\dfrac{2}{15}[/tex]

Therefore, she is riding [tex]\dfrac{2}{15}[/tex] miles per minute.
