Answer

d=25+15x I think

Step-by-step explanation:

first box on the left

r=4

d=8

circumference= 2π*4= 8π

area = π*4*4= 16π

Second box on the left

d=6

r= 3

circumference= 2π*3= 6π

area =π*3*3= 9π

third box on the left

A=36π

A=36πarea= π*r*r

A=36πarea= π*r*rr= 6

A=36πarea= π*r*rr= 6d=12

A=36πarea= π*r*rr= 6d=12circumference= 2π*6= 12 π

the last box

C=18π

C=18πC= 2π*r

C=18πC= 2π*rr= 9

C=18πC= 2π*rr= 9d=18

C=18πC= 2π*rr= 9d=18area= π*9*9= 81π

Answer:

714 is the total number that is sold, if there is 64 more tickets sold for students then adults, then do 714 divided by 2 and add 32 to get the number for students, and for adults do 714 divided by 2 and subtract by 32. so, like this 714/2+32=389 tickets for students and 714/2-32=325 for adults. Hope this helps

Answer:

The adult tickets total were 293

Step-by-step explanation:

714 divided by 2 ( because there is only 2 types of tickets )  and 714 divided by 2 equals 357 ad because the student tickets sold better 357 minus 64 = 293 and you prove that by multyplying 357 x 2 = 714

your welcome :)

Answer:

x=9

Step-by-step explanation:

2(x-1)=3x-11

distribute the 2

subtract 2x from both sides and get -2=x-11

add 11 to both sides and get x=9

Answer:

time left for question C = 12 1/2

Step-by-step explanation:

Total time required for the three quiz= 30 minutes

 time spent on question A= 10 9/10 minutes

Time spent on question b= 6 3/5 minutes

Time spent on Question c= Total time required for the three quiz -( time spent on question A+Time spent on question b)

30 - ( 10 9/10 + 6 3/5)

30 -16   (9+ 6/10)

30- 16 15/10( 15/10 = 1   5/10)

30 - 16  + 1 5/10

30 - 17 5/10

From 30, we remove 1 whole number to subtract the fraction from the other number so we have

29 - 17 ( 1 -5/10)

=12 5/10 = 12 1/2

Answer:

The value of C is 3

Step-by-step explanation:

all of the angles of a triangle add up to 180°. first you would add 92 and 46 and get 138. You then subtract 180 and 138 and get 42. then you divide 42 by 14 and get 3. then substitute 3 back into the equation and you get 180.

Answer: 24 goals

Step-by-step explanation:

Melissa makes 2 goals out of every 12 shots on goal.

This means that the amount of shots needed to score a goal for her is:

= Number of shots / Number of goals

= 12 / 2

= 6 shots

She scores a goal every 6 shots.

If she makes 144 shots therefore, she will score:

= Number of shots / Number of shots needed per goal

= 144 / 6

= 24 goals

Answer:

Total revenue = $13,250

Amount given for charity = $7,950

Step-by-step explanation:

Children = $10

Adults = $25

Total people = 800

ratio of adults to children was 7:9.

Total ratio = 7 + 9 = 16

Adults = 7/16 × 800

= 0.4375 × 800

= 350

Adults = 350

Children = 9/16 × 800

= 0.5625 × 800

= 450

Children = 450

Total revenue = ($10 × 450) + ($25 × 350)

= $4,500 + $8,750

= $13,250

Total revenue = $13,250

60% of the tickets cost was given to charity.

Amount given for charity = 69% of $13,250

= 0.60 × $13,250

= $7,950

Amount given for charity = $7,950

Answer:

C

Step-by-step explanation:

Mitochondria is the powerhouse of a cell

This is just the same as asking you what number when subtracted by 20.5 will give you an answer of 8. The answer would obviously be 8+20.5=28.5 so w=28.5.

We can also do it in a more algebraic way. By adding 20.5 to both side of the equation which won't change the value.

w-20.5+20.5=8+20.5

w=28.5

Answer:

6.28 + 24 + 3 + 2 = 35.28 sq. units

Step-by-step explanation:

The screenshot is how I split it. (A semicircle with a radius of 2, a trapezoid (base a: 5, base b: 7, height 4), and two triangles (b1: 3, h1: 2; b2: 4, h2: 1)

To find the area of a semicircle, use the formula πr²/2. I'll use 3.14 for pi.

3.14(2²)/2

Square 2 to get 4.

3.14(4)/2

Multiply 3.14 by 4 to get 12.56.

12.56/2

Divide 12.56 by 2 to get 6.28

The semicircle is 6.28 units².

To find the area of a trapezoid, use the formula (a+b)h/2.

(5 + 7) * 4/2

Add 5 and 7 to get 12.

(12 * 4)/2

Multiply 12 by 4 to get 48.

48/2

Divide 48 by 2 to get 24.

The trapezoid is 24 units².

For the triangles, simply use this: bh/2

3 * 2 / 2

The 2's cancel out, so you're simply left with the first triangle being 3 units².

4 * 1 / 2

This really just becomes 4/2 as 4 * 1 is just 4.

4/2

Divide 4 by 2 to get 2.

The second triangle is 2 units².

Now that we know the areas of the four figures, add them together.

6.28 + 24 + 3 + 2

6.28 + 27 + 2

6.28 + 29

The area of the figure is 35.28 units².

Answer:

19.9

Step-by-step explanation:

we can write the following equation

18000(1.02)^n

where n is the number of years

so we have

26700=18000(1.02)^n

solve for n

1.483=1.02^n

use logs to solve for n

n=19.9
