# H=10 cm r= 7cm calculate the volume of the cylinder ​

V = 1538.6 cm^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2h  where r is the radius and h is the height

V = pi (7)^2 10

V = 3.14 (49)10

V = 1538.6 cm^3

≈ 1539.3804

Step-by-step explanation:

V= πr²h =π*7²*10

Ashley, Milan, and Carlos sent a total of 131 text messages over their cell phones during the weekend. Carlos sent 7 times as many messages as Ashley. Ashley sent 4 more messages than Milan. How many messages did they each send?

Ashley= 15

Milan= 11

Carlos= 105

Step-by-step explanation:

Let, A, M and C denotes Ashley, Milan and Carlos respectively.

A+M+C= 131 (according to the question)

Here,

C= 7A

A= M+ 4

So, M= A - 4

Now,

A+M+C = 131

or, A+ A-4+ 7A = 131 (putting the values)

or, 9A - 4 = 131 (adding like terms i.e. A + A + 7A)

or, 9A = 131 + 4

or, 9A = 135

or, A = 135 / 9

So, A = 15

C= 7A = 7×15= 105

M= A-4 = 15 - 4 = 11

Use the data set to create a quadratic function if it applies. Use the model to predict the value of x when y = -4. (-3, 10), (0, 4), (3, -1), (6, -5), (9, -8)

Question 3 options:

A)

29.32 and 3.97

B)

32.27 and 4.57

C)

No Solution

The closest choice is ...

C)  27.48 and 5.20

### Step-by-step explanation:

Using the equation ...

y = ax² + bx + c

You can substitute the first three points to get linear equations in a, b, and c.

10 = a(-3)² +b(-3) +c = 9a -3b +c

4 = a(0)² + b(0) +c = c

-1 = a(3)² + b(3) +c = 9a +3b +c

The second equation tells us c=4. Subtracting the first equation from the last, we get ...

(9a +3b +c) -(9a -3b +c) = (-1) -(10)

6b = -11

b = -11/6

Then we can find "a" from the first equation:

10 = 9a -3(-11/6) +4

1/2 = 9a . . . . subtract 19/2

1/18 = a . . . . . divide by 9

The model is ...

y = (1/18)x² -(11/6)x +4 . . . . . . . . [call this "model A"]

y = (x² -33x +72)/18

Solving this for y = -4, we have ...

-4 = (x² -33x +72)/18

x² -33x +144 = 0 . . . . . . multiply by 18, add 72

(x -16.5)² -128.25 = 0 . . . . put in vertex form

x = 16.5 ±√128.25 ≈ {5.17525, 27.8248}

___

The closest values to these among the choices offered are those of choice C. It appears that the coefficients of model A were rounded to 3 decimal places (or so) before the predicted x-values were computed.

Jane Hilman went to her bank. She had a balance of \$1,009.88 in her savings account. She withdrew \$130.00 and the teller credited her account with \$6.19. What is her new balance?

Step-by-step explanation:

I chose the first one. To compare the two products and find the better buy, let's find the cost of 1 ounce of cereal in each box. The unit rate for the left box will be \$2.15 / 14 = \$0.15 per ounce. The unit rate for the right box will be \$3.40 / 20 = \$0.17 per ounce. Because 0.15 < 0.17, the box on the left is the better buy. Hope this helps!

2.15/14=0.153

3.4/20=0.17

Option A. is better because the price is smaller

4.50/3=1.5

5.96/4=1.49

option b is better

2.41/4=0.6025

1.8/2=0.9

option b is better
