Answer:

$0.45 or 45 cents

Step-by-step explanation:

If i'm not mistaken.

in one pound, there are 16 ounces. Therefor, just divide 7.20 by 16 and you get 0.45. or 45 cents.

Hope this helps, brainliest is appreciated! :)

Answer:

Step-by-step explanation:

The volume of the original cylinder = pi * r^2 * h

Givens

r = 6 in

h = 3 in

pi = 3.14

Solution

V = pi * r^2 * h

V = 3.14 * 6^2* 3

V = 3.14 * 36 * 3

V = 339. 12

Part 2

If you double the height, you will double the volume

V = 3.14 * 36 * 6

V = 678.24

Answer:

A. -6

Step-by-step explanation:

The slope of the line that is perpendicular to the graph y = ⅙x + 8, is a negative reciprocal of the slope of the graph, y = ⅙x + 8.

What this means is that, if you multiply the slope of y = ⅙x + 8, and the slope of the line perpendicular to it, you would have -1. That is [tex] m_1 * m_2 = -1 [/tex].

Where,

[tex] m_1 [/tex] = slope of y = ⅙x + 8.

[tex] m_2 [/tex] = slope of the line perdendicular to y = ⅙x + 8.

The slope of y = ⅙x + 8 is ⅙.

Substitute [tex] m_1 [/tex] = ⅙ into [tex] m_1 * m_2 = -1 [/tex], to find the slope [tex] (m_2) [/tex] of the line that is perpendicular to the graph of y = ⅙x + 8.

[tex] \frac{1}{6} * m_2 = -1 [/tex]

Multiply both sides by 6

[tex] \frac{1}{6} * m_2 * 6 = -1*6 [/tex]

[tex] 1*m_2 = -6 [/tex]

[tex] m_2 = -6 [/tex]

The slope of the line that is perpendicular to the graph of y = ⅙x + 8 is -6.

Answer:

x=5

Step-by-step explanation:

f(x) = -2x and g(x) = 4x - 8, find h(x) = f(x) + g(x).

Replace f(x) and g(x) with their given values:

h(x) = -2x + 4x -8

Combine like terms:

h(x) = 2x -8

Answer:

x^2 -1 - 5(x-1)

Step-by-step explanation:

p(x) = x^2 - 1 and q(x) = 5(x - 1)

p(x) - q(x) = x^2 - 1 - ( 5(x-1))

               Distribute

                = x^2 -1 - 5(x-1)

Considering the perimeter of the rectangular table, it is found that 36 ballons are needed.

The perimeter of a rectangle of length l and width w is given by:

P = 2(l + w).

In this problem, the dimensions of the table are l = 8 ft and w = 4 ft, hence the perimeter is of:

P = 2(l + w) = 2 x 12 = 24 ft.

Ballons will be attached 8 inches = 2/3 feet along the perimeter, hence the number of ballons needed is given by:

On factorization of the equation x² − x − 6 = 0. Then the values of x are −2 and 3.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The equation is given below.

x² − x − 6 = 0

On factorization, we have

 x² − 3x + 2x − 6 = 0

x(x − 3) + 2(x − 3) = 0

       (x − 3)(x + 2) = 0

                         x = −2, 3

The values of x are −2 and 3.

Answer:

f(- 2) = 4

Step-by-step explanation:

substitute x = - 2 into f(x) , then

f(- 2) = - (- 2) + 2 = 2 + 2 = 4

Answer:

Given function:  [tex]f(x)=-x+2[/tex]

To evaluate the function when [tex]x=-2[/tex], substitute the given value for [tex]x[/tex] into the function and solve:

[tex]\implies f(-2)=-(-2)+2[/tex]

[tex]\implies f(-2)=2+2[/tex]

Answer:

p = 6, q = - 1

Step-by-step explanation:

Using the rules of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , [tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]

Given

xy = 32 , tat is

[tex]2^{p}[/tex] × [tex]2^{q}[/tex] = [tex]2^{5}[/tex]

Since the bases on both sides are equal, equate the exponents

p + q = 5 → (1)

Also

2xy² = 32 ( divide both sides by 2 )

xy² = 16 , that is

[tex]2^{p}[/tex] × [tex](2^{q}) ^{2}[/tex] = 16

[tex]2^{p}[/tex] × [tex]2^{2q}[/tex] = [tex]2^{4}[/tex] , then p + 2q = 4 → (2)

Thus

p + q = 5 → (1)

p + 2q = 4 → (2)

Subtract (1) from (2) term by term

q = - 1

Substitute q = - 1 into (1) for corresponding value of p

p - 1 = 5 ( add 1 to both sides )

p = 6

Answer:

(A.) 1/9

Step-by-step explanation:

So there are 9 options to choose from and the question asked about 2 of them.

I took those 2 and multiplied them by 9 which gave me 18.

So I put 2 over 18 which can be simplified by 2.

So my final answer was 1/9.

[tex]2 * 9 = 18\\\\\frac{2}{18} = \frac{1}{9}[/tex]

Answer:

y = 1/4x + 17/4

Step-by-step explanation:

first lets umm find the slope

use points that you can um clearly see ?

(4, 6) and (8, 7)

so use the equation y2 - y1/ x2 - x1

soooo

7 - 6/ 8 - 4

1 / 4

so it looks like:

y = 1/4x + b

so far

now we have to find the y-intercept with a point we did not use yet

but i have a little trouble so ill try my best to estimate a point

(2, 5)

we substitue

5 = 1/4(3) + b

5 = 3/4 + b

b = 5 - 3/4

b = 17/4

i want to check but its hard looking for exact points. i think this is the answer hope this helps!

Answer:

People in the U.S. Will spend 18.2 billion dollars on statins in 2005.

Step-by-step explanation:

Given:

S − 1.9x = 4.9

Where,

S = sales of statin in billions of dollars

x = years after 1998

how much will/did people in the U.S. Spend on statins in the year 2005?

2005 is a year after 1998

Number of years = 2005 - 1998

= 7

x = 7 years

S − 1.9x = 4.9

S - 1.9(7) = 4.9

S - 13.3 = 4.9

Add 13.3 to both sides

S = 4.9 + 13.3

= 18.2

People in the U.S. Will spend 18.2 billion dollars on statins in 2005.

Answer:

[tex]\frac{29,x\leq 250}{29+0.35(x-250)x\geq 250}[/tex]

Step-by-step explanation:

Let x represent the total time spent calling and f(x) represent the charges.

Since Tracy is charged $29 for 250 free minutes, hence:

For x ≤ 250, f(x) = $29

Tracy is charged an extra $0.35 per minute for calls over 250 minutes, hence:

For x ≥ 250, f(x) = 29 + 0.35(x - 250)

Therefore this can be represented by the piecewise function:

f(x)=  [tex]\frac{29,x\leq 250}{29+0.35(x-250)x\geq 250}[/tex]
