What is the formula for area of a circle?


A = pi x D


A = pi x r2

A = 2pi x r


A = pi x D2

Answer:

4 < x < 12

Step-by-step explanation:

8 - 4 = 4

8 + 4 = 12

So the side has to be greater than 4, but less than 12. Hope this helps!

Answer:

Amount with Salma = $ 23

The amount with Chris =  $69

Amount with Jim =  $ 32

Step-by-step explanation:

Let the amount with Salma = $ x

The amount with Chris = 3*x = 3x

Amount with Jim = x + 9

Total in their wallets = $124

x + 3x + x +9 = 124                 {combine like terms}

5x+ 9 = 124           {Subtract 9 from both sides}

5x  = 124 - 9

5x = 115   {Divide both sides by 5}

x = 115/5

x = 23

Amount with Salma = $ 23

The amount with Chris = 3*23 = $69

Amount with Jim = 23 + 9 = $ 32

Answer: Jim has $32 Chris has $69 and salma has $23

Step-by-step explanation: 124-9=115 115/5 =23 and that’s how you get salma‘s. then 23x3= 69 that’s Chri’s then 23+9 =32 that’s Jim’s

Answer:

She sold 39 tall candies and 52 short candies

Step-by-step explanation:

x is all the tall candies

y is all the short candies

x+y=91

8x+5y=572

Use the method of Substitution to find out both x and y.

x=91-y

8(91-y)+5y=572

728-8y+5y=572

728-3y=572

3y=156

y=52

x+52=91

x=39

Answer: f(x)=3x^2-17x+10 (in other words the bottom one)

Step-by-step explanation:

Answer:

  last option is correct

f(x)=3x^2−17x+10

Step-by-step explanation:

3x^2−17x+10=0

using the Quadratic Formula where

a = 3, b = -17, and c = 10

x=−b±√b2−4a/2a

x=−(−17)±√(−17)2−4(3)(10)/2(3)

x=17±√289−120/6

x=17±√169/6

x=(17±13)/6

x=30/6    ,   x=4/6

x=5  ,  x=2/3

I think the question 26 on the first page is C sorry if I'm wrong

Step-by-step explanation:

Answer:

26 is c, 20 is b, 30 is c

Step-by-step explanation:

26:

The relationship between 2,560 and 256 is that 2,560 is 10 times 256, and the only options that include "10 x" is b and c and b has (2+5+6) which doesn't equal 256, whereas c does.

20:

The bottom layer is 15 blocks, so then add the two more on top of the bottom layer and it's 17, so b.

30:

The width of the prism is 2, the length is 8, and the height is 4, so 2x8x4 is 64. They want a prism that's 1/4 the volume, so 64/4 is 16. (You could also just take 4 out of the 2x9x4 equation and get 2x8 which is 16).

Answer:

$16.74

Step-by-step explanation:

First of all, 15% of $18 is $2.7. $18 - $2.7 = $15.3. Then, 8% of $18 is $1.44. So, $15.30 + $1.44= $16.74, supposing that the sales tax was of the original price, and not of the 15% off price.

Answer:

1. y = 40x

2. y = 90x

Step-by-step explanation:

In the graph, for every one unit to the right, the graph increases by forty (up forty, over one). Since x is the unknown number of months, and it’s $40/month, y = 40x. After they raise the prices, it is $90 every month, so now it’s y = 90x. Hope this helps!

Answer:

1) y = 40x

2) y = 45x

x = months

Step-by-step explanation:

1) 40/1 = 40

2) 90/2 = 45

Answer:

The median of the data for Farm Y is greater than the median of the data for Farm X.

Step-by-step explanation:

The median is the middle of the box plot. Median is the middle. If you have to find it on a box plot, look at the box and find the line directly in the middle/the only line IN the box. If it's a list of numbers, you have to put them in order first. Then, find the center number, if it is even, you add the two numbers and divide by two.

Range is when you subtract the largest number by the smallest number.

Third quartile is 75% of the box plot. If you look at the box plot, third quartile is the line that makes up the right side of the box.

First quartile is 25% of the diagram. The first quartile is the left line that makes up the box.

Mode is the number that appears the most often.

Mean is when you add all the numbers together. Then, divide the sum by how many numbers you added.

Answer:

1. 45 minutes a day cycling

2.$1.55 on each cup of coffee a day

Step-by-step explanation:

1. You would figure up how much he jogs per week by multiplying 15 times 5 which would be 75 minutes and then from there you would subtract 75 from 300 and get 225 and divide 225 and 5 and end up with 45

2. You would multiply $.75 by 4 to figure up how much he spends on donuts which is $3 and then subtract  15.40 from 3 and get 12.40 and divide 12.40 by 8 since he goes twice a day and end up with 1.55
