Answer:

\boxed{ \bold{ \huge{  \boxed{ \sf{1190 \: dollars}}}}}

Step-by-step explanation:

Cost of 4 TVs = $ 680

<u>Finding</u><u> </u><u>the</u><u> </u><u>cost</u><u> </u><u>of</u><u> </u><u>1</u><u> </u><u>TV</u>

\sf{ \frac{680}{4} } = 170 \: dollars

<u>Finding</u><u> </u><u>the </u><u>cost</u><u> </u><u>of</u><u> </u><u>7</u><u> </u><u>TVs</u>

Since, the cost of 7 TVs is more than that of 1 TV. So, the cost of 1 TV is multiplied by 7

\sf{i.e \: 170 \times 7 = 1190 \: dollars}

Hope I helped!

Best regards! :D

Answer:

We find cost per one from all cost per number of sales = 680/4 = $170 per one.

Then we calculate 7 TVs cost by cost per one × number of sales = 170×7 = $1190

The lateral area of a cylinder is 325 pi inch^2. The radius is 13 in. Find the surface area and volume. Please show all work!!!
USPshnik [31]
Answer:

Surface area =  663π in².
Volume = (676/3)π in² ≈ 225.33 π in²

Explanation:


1) We know the radius and the lateral area.

2) With the radius you can find the areas of the top and the bottom.

For that, you use the formula: 

area of the top = area of the bottom = π r² 


∴ π (13 in)² = 169π in² (each)


3) Then, the surface area is the sum of the lateral area and the two bases (top and bottom)

surface area = lateral area + bottom area + top area = 325π in² + 2×169π in² = 663π in².

3) You  can also find the height of the cylinder.

Use the formula: lateral area = 2π r h


∴ h = lateral area / [2 π r]

⇒ h = 325 π / [ 2π (13) ] = 12.5 in


4) With  the height you can find the volume.

Use the formula: V = (4/3) π r³ 

∴ V = (4/3) π (13 in)³ = (676/3)π in² ≈ 225.33 π in²

Suppose a + b = 0.
Digiron [165]
I'm pretty sure that it's b. That's assuming that you find the negative of b^2 and not the square of negative b.

A student draws a triangle with a perimeter of 36cm. The student says the longest length is 18cm. How do you know the student is
Crazy boy [7]

The length of the first two sides of a triangle must be greater than the length of the last side.  If the longest length were 18, the first two sides would be too short.  36-18=18, 18 is equal not greater than 18 which means the sum of the first two sides are too short.
