Answer:

The correct answer is

Step-by-step explanation:

Snow cone holders are sold in sleeves of 50.

The cones have a slant height (l) of 5 inches and a radius (r) of 3 inches.

Surface area of each cone holder = π × r × l = π × 15 = 15π square inches.

Surface area of all 50 cones in the sleeve = 15π × 50 = 750π = 2357.143 square inches.

Thus 2357.143 square inches pf paper would be necessary for each sleeve each having 50 cone holders.

Would you please help me solve for x it should be a degrees but I’m not sure what it is
Leno4ka [110]

Answer:

x=15º

Step-by-step explanation:

A triangle's angles add up to 180º.

∠A=30º

∠C=180º-45º

∠B=xº

To find ∠B we have to first find ∠C.

Since ∠C does not have an angle, knowing that a straight line is 180º we can subtract it from 45º to find ∠C.

180-45=135

∠C=135º

Now add ∠A and ∠C.

30+135=165

Subtract the sum from 180º

180-165=x

x=15º

Hope this helps :)

A heat pump cycle whose coefficient of performance is 2.5 delivers energy by heat transfer to a dwelling at a rate of 20 kW.
jasenka [17]

Answer:

Net power = 20kW

B.) $128

Step-by-step explanation:

Given that :

Coefficient of performance = 2.5

Rate = 20kW

The net power required to operate the heat pump :

Energy delivery rate / Coefficient of performance

= 20kW / 2.5

= 8kW

B.) Given that electricity cost equals $0.08 per kW

If pump operates for 200 hours

Total energy used in kWhr :

8kW * 200= 1600kW

Cost per kW = $0.08

1600 * 0.08 = $128
