ASKING FOR A LONG TIME PLS HELP GONNA MAKE BRAINLIEST all i know is 20 2/3 is not right. TYSM

area of a circle = [tex]\pi r^{2}[/tex]

circumference =[tex]2\pi r[/tex]

Okay so the center of the circle is the same for both of the circles lets take that value as m so the radius of the inner circle is 54 - m

we have the circumference of the inner circle which is 270.04 we can find the value of m using that

[tex]270.04=2\pi (54-m)\\270.04= 339.2-6.28m \\6.28m = 339.2-270.04\\m= 11.02[/tex]

the radius of the inner circle is therefore 42.98

and the full circle has a radius off 65.02

area of shaded region = area of full circle - area of inner circle

area of shaded region = [tex]\pi (65.02)^{2} - \pi (42.98)^{2}[/tex]

area of shaded region = [tex]13281.39 - 5803.4[/tex]

area of shaded region = 7478 rounded off to the nearest whole number

Answer:

zero ...I know you just sharing the points.

Answer:

[tex]n=4[/tex]

Step-by-step explanation:

Expand  −2(1−7n):    −2+14n

5n+34=−2+14n

Subtract 34 from both sides

5n+34−34=−2+14n−34

Simplify

5n=14n−36

Subtract 14n from both sides

5n−14n=14n−36−14n

Simplify

−9n=−36

Divide both sides by −9

−9n

−9 =

−36

−9

Simplify

hi

4 entries are  24   so one  entry is  24/4 = 6  

so 7 friends pay  6*7 = 42

5x+7y=25

5x-2y=-65

subtract both of the equations

5x-5x=0

7y--2y= 7y+2y=9y

25--65=25+65=90

0+9y=90

9y=90

divide both sides by 9 to get y by itself

9y/9=90/9

cross out 9 and 9 which becomes 1*1*y=y

90/9=10

y=10

find x by using the substitution method

5x+7y=25

5x+7(10)=25

5x+70=25

move +70 to the other side

sign changes from +70 to -70

5x+70-70=25-70

5x=-45

divide both sides by 5 to get x by itself

5x/5=-45/5

cross out 5 and 5 then becomes 1*1*x=x

-45/5=-9

x=-9

answer:

(-9,10)

Answer:

shading three boxes

Step-by-step explanation:

It is given that :

The body weight of an average adult = 60%

We have to show this by shading the square boxes shown.

There are 5 square boxes in total which makes up 100%.

So divide 100 by 5, we can 20% for each box.

So, 20% + 20% + 20%  will give us 60%

Therefore, shading three boxes will give us 60% which is the water percent in an average adult's body weight.

This is represented by the figure below.

Step-by-step explanation:

4x - 5y = -20

-5y = -4x -20

y = 4/5x + 4

Answer:

x = -5  y = -5

Step-by-step explanation:

–x + 4y = -15

     - 4y  -4y

-1(-x = -4y - 15)

x = 4y + 15

Substitute x = 4y + 15 into 3x + 5y = -40

3(4y + 15) = -40

17y + 45 = -40

      - 45   -45

17y = -85

/ 17    /17

y= -5

Substitute y = - 5 into x = 4y + 15:

x = 4(-5) + 15

x = -20 + 15

x = -5

Answer:

Part I

(-5,-5)

Part II

(3.75, 312.50)

Step-by-step explanation:

Part I

(1) 3x + 5y = -40

(2) -x + 4y = -15

solve for x in (2)

x = 15 + 4y

substitute into (1)

3(15+4y) + 5y = -40

45 +12y + 5y = -40

45 +17y = -40

17y = -85

y = -5

substitute y = -5 into (1)

3x + 5(-5) = -40

3x -25 = -40

3x = -15

x = -5

so  (-5, -5)

Part II

Studio A  

C = 125 + 50t

Studio B

C = 200 + 30t

125 + 50t = 200 + 30t

20t = 75

t = 3.75

Answer:

2 1/6 feet

Step-by-step explanation:

A carpenter has a board that is 8 feet long. He cuts off two pieces. One piece is 3 1/2 feet long and the other is 2 1/3 feet long. How much of the board is left?

Total length of the board = 8 feet

Piece A = 3 1/2 feet

Piece B = 2 1/3 feet

Piece A + piece B

= 3 1/2 feet + 2 1/3 feet

= 7/2 + 7/3

= (21+14) / 6

= 35/6

= 5 5/6 feet

Length of the board remaining = Total length of the board - length of the two pieces

= 8 feet - 35/6 feet

= (48-35) / 6

= 13/6 feet

= 2 1/6 feet

Length of the board remaining = 2 1/6 feet

Answer:

a = 5120

b = 1.25

Step-by-step explanation:

Let the exponential function representing the given table is,

f(x) = [tex]a(b)^x[/tex]

Here, f(x) = Number of views

x = Number of weeks

We choose two points from the given table and satisfy the equation of the function.

Let the points are (0, 5120) and (1, 6400)

For a point (0, 5120),

f(0) = a(b)⁰ = 5120

a = 5120

Now for the second point (1, 6400),

6400 = 5120(b)¹

b = [tex]\frac{6400}{5120}[/tex]

b = 1.25

Therefore, a = 5120 and b = 1.25 are the values.

Answer:

f(x)=8(0.5)^x

Answer: 5%

Step-by-step explanation:

Since Ryan's take-home pay is $2,500 each month and the amount for gas is $125.

The percentage that Ryan uses on gas from his take-home pay will be:

= Amount used on gas / Take home pay × 100

= 125/2500 × 100

= 1/20 × 100

= 5%

He used 5% on gas.

Answer:

The miles per day are: 3 1/12.

Step-by-step explanation:

With  the information provided, in order to find the miles per day you have to divide the number of miles he walked by 3 that is the number of days:

9 1/4÷3

In order to solve this, first you have to convert the mixed number to an improper fraction by multiplying the denominator for the whole number, add the numerator and this would be divided by the denominator:

(4*9)+1/4

36+1/4

37/4

Now, you divide this by 3:

37/4÷3

37/(4*3)

37/12

You can conver this fraction into a mixed number by dividing 37 by 12. 12 goes into 37 three times which would be the whole number. Then, three times 12 is 36 and the remainder is 1. So, 1 would be the numerator and the denominator stays th same which is 12. The mixed number is: 3 1/12.

According to this, the answer is that the miles per day are: 3 1/12.

Answer: 550

Explanation:

Well first, you need to solve 40 percent of 900 (which is 360) then subtract it from the main amount (900)

So 900-360

Answer:

360

Step-by-step explanation:

So we have 40% and 900 people. Before we ask ourselves what is 40 percent of 900, lets ask ourselves what is 10 percent. So 10 percent of 900 would be 90 because you have to move the decimal point 1 unit to the left.        

Now, 40 percent is 4 times the value of 10 percent so 40 percent of 900 has to be 360, because 90 times 4 is 360.

And you can check it by multiplying 900 x .40 which would be 360

Hope this helped, good luck :)

Answer: 280 children

Explanation: Each grade has 70 kids. You have 4 total grades (3rd, 4th, 5th, and 6th grade). You have to add the number of kids you have in every grade. In this case, 70 children in 3rd grade, 70 children in 4th grade, 70 children in 5th grade, and 70 children in 6th grade. The problem would look like this:

70 + 70 + 70 + 70

Then your answer is 280 when you add them all together!

Answer:

45.5

Step-by-step explanation:

First you would find 1/3 third of 10.50 and it is 3.5, you would then do 10.50 x 4 since it said 10.50 per half a yard, so you would do times 4 and you would get 42, you would then add 42 + 3.5 which equals 45.5.

I would appreciate brainliest, have an amazing day

Answer:

A

Step-by-step explanation:

We can solve this problem by eliminating wrong answers

It can be b because there is no 3

It can be c because the equation would be 4+3

And it can be d because the equation would be 3x+4

so it must be a

Answer:

option A is correct

as additional page costs is not fixed so there will be any value of x with multiply by 4

and the fixed remain only one time so it remains fixed and 3 is also fixed.
