Answer:

About $48.39

Step-by-step explanation:

Sales tax only applies to the bill, not the tip.

Calculate the sales tax:

38.96 × 8%

38.96 × 0.08

3.1168

Round to the nearest cent:

3.12

Add the sales tax to the bill:

38.96 + 3.12

42.08

Calculate the tip based "on the total amount of the bill:"

42.08 × 15%

42.08 × 0.15

6.312

Round to the nearest cent:

6.31

Add the tip to the rest of the bill:

42.08 + 6.31

48.39

Answer:

1230.88

Step-by-step explanation:

The volume of a cylinder is given by

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

V = (3.14) * (7)^2 * 8

V = 3.14 * 49*8

V =1230.88

4x + 3(2x - 4) = x

Step 2: Solve for x

Answer:

x = 1.33

Step-by-step explanation:

4x + 3(2x-4) = x

-4x                 -4x

3(2x-4) = -3x

Distribute 3 to (2x-4)

6x - 12 = -3x

-6x           -6x

-12 = -9x

/-9     /-9

1.33 = x

Answer:

Mean = 78 ;

Standard deviation = 14

Step-by-step explanation:

Given that:

Mean score = 68

Standard deviation = 14

When a constant value is added to the individual value of a dataset, the new mean value will become the sum of the initial mean value and the constant term added to the values.

Constant Added score = 10

The mean of scaled test score will be:

Mean score + constant added score

68 + 10 = 78

The standard deviation remains unchanged ; Hence, standard deviation = 14

Answer:

Amount of interest received by Phoebe = $300

Step-by-step explanation:

Given:

Amount Phoebe invested = $5,800

Amount Phoebe received after one year = $6,100

Find:

Amount of interest received by Phoebe

Computation:

Amount of interest received by Phoebe = Amount Phoebe received after one year - Amount Phoebe invested

Amount of interest received by Phoebe = 6,100 - 5,800

Amount of interest received by Phoebe = $300

Step-by-step explanation:

In order to find the surface area of a 3-dimensional figure, one must find the 2-dimensional area of all of its faces, then add up the values to find the surface area of the entire figure. The given prism is drawn out in the form of a net, thus, it is rather easy to find the area of each face, and add up the area to find the surface area.

The lateral surface area refers to the surface area of a figure, not including the base of the figure. In this case, the base is the largest rectangle: the one with the dimensions of the following length  

[tex](12)*(18)[/tex]

Use the following formulas to find the surface area of each face:

Rectangle: [tex](length)(width)[/tex]

[tex](10)(18)=(180)[/tex]

[tex](10)(18)=(180)[/tex]

Triangle:[tex]\frac{(base)(height)}{2}[/tex]

[tex]\frac{(12)(8)}{2}=48[/tex]

[tex]\frac{(12)(8)}{2}=48[/tex]

Add up all of these values to find the total surface area:

[tex](180)+(180)+(48)+(48)=456[/tex]

Hi,

I cannot see the options but for vertical compression you need to have values of a that are 0<a<1, then the graph will be compressed.

For example, if we have g(x)= 1/2 x^2 will be compressed by factor of 1/2.

Answer:

$8.99

Step-by-step explanation:

1 pound = 16 ounces

y pound = 8 ounces

[tex]\frac{1}{16} :\frac{y}{8}[/tex]

y · 16 = 1 · 8

16y = 8

16y ÷ 16 = 8 ÷ 16

y = 0.5

0.5 pound = 8 ounces

----------------------------------

1 pound = $17.98

0.5 pound = y

[tex]\frac{1}{17.98} :\frac{0.5}{y}[/tex]

y · 1 = 17.98 · 0.5

y = $8.99

Answer:  A) -6x-4 Hope that helps!

Step-by-step explanation:

1. Expand by distributing terms -4(x+2)-2x+4

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

2. Remove parentheses

-4x-8-2x+4

3. Collect like terms

(-4x-2x)+(-8+4) and simplify meaning multiply if you do -4×-2= -6 and if you do -8+4= -4 So, your answer would be -6x-4 never forget the variable that's the letter that I put went the x in it by the way and can you make me Brainliest please thanks and bye!

Answer:

(a.)

=(6x^2-3x)+(8x-4)

=3x(2x-1)+4(2x-1)

=(2x-1)(3x+4)

zeros are x=-4/3, x= 1/2

(b.)

=4(x^2-16)

=4(x+4)(x-4)

zeros are x= -4 and x= 4
