Find the area of trapezoid.

1/2(6+10)(3) = 24

Now multiply 24 by $4 to find the total cost.

24 * 4 = 96

So the total cost is $96

Hope this helps :)

Translate into an algebraic expression and simplify if possible. I have a total of 10 gigabytes of data on my computer, xgigabyt
pogonyaev

Answer:

(20-3x)/2 GB

Explanation:

Total amount of data on my computer = 10GB

Total amount of data occupied by movies = x GB

If pictures take up half the amount of space that movies do, then;

Total amount of data occupied by pictures = 1/2 of space occupied by movies = 1/2 x

If the remaining are music, the amount of space occupied by music will be expressed as shown;

Total space -(space occupied by movies + space occupied by pictures)

= 10 - (x+1/2 x)

Total amount of data occupied by music = 10 - (x+1/2 x) GB

On simplification;

= 10 - (x+1/2 x)

= 10-{(2x+x)/2}

= 10 - {3x/2}

= (20-3x)/2 GB

Hence, amount of gigabytes of music stored on my computer is expressed as (20-3x)/2 GB.

The volume of a cylindrical container
Ray Of Light [21]

Answer:

A. \frac{3}{4}\textrm{ gal}

Step-by-step explanation:

Given:

Volume of the cylindrical container before dilation, V_{i}=1\textrm{ gal}

Scale factor of the dilation, SF=\frac{3}{4}

Therefore, the volume of the dilated cylinder is given as:

V_{f}=SF\times V_{i}

Plug in 1 gal for V_{i} and \frac{3}{4} for SF. Solve for V_{f}. This gives,

V_{f}=\frac{3}{4}\times 1\\V_{f}=\frac{3}{4}\textrm{ gal}

Therefore, the volume of the dilated cylinder is \frac{3}{4} gallons.

Jimmy cell phone plan has been a base charge of $50 per month with an additional charge of 65 cents per app downloaded. Lisa cel
Soloha48 [4]

Answer:

20

Step-by-step explanation:

We write what we know.

Jimmy

$50/mo   app 65¢ or .65

Lisa

$55/mo   app 40¢ or .40

a = number of apps

The difference will come from the number of apps, a.

We need them to equal each other so let's write an equation.

$50 + .65a = $55 + .40a

We need to solve for a.

$50 + .65a = $55 + .40a     subtract $50 for each side.

$50 - $50 + .65a = $55 - $50 + .40a

.65a = $55 - $50 + .40a

.65a = $5 + .40a     subtract .40a from each side

.65a - .40a = $5 + .40a - .40a

.65a - .40a = $5

.25a = $5   Divide each side by .25

.25a/.25 = $5/.25

a = $5/.25

a = 20

So Jimmy and Lisa need to download 20 apps for their bill to be the same.

Help find y .. slope is m=-5/8
goblinko [34]

y = 8

using the ' gradient formula' m = (y₂ - y₁)/(x₂ - x₁)

with (x₁, y₁) = (3, 3), (x₂, y₂) = (- 5, y) and m = - \frac{5}{8}

(y - 3)/( - 5 - 3) = - \frac{5}{8}

(y - 3)/(-8) = - \frac{5}{8}

multiply both sides by - 8 to eliminate fractions

y - 3 = 5

add 3 to both sides

y = 5 + 3 =8
