Answer:
It will take 58 seconds
Step-by-step explanation:
If you have 1 kg of water in the jar, half of it will be 0.5 kg.
To vaporize half of the water (0.500 kg) the energy supply needed is

If the stove is supplying 20 kJ/s, the time its needed is

It will last at least 58 seconds to vaporize half of the water.
Based on the lengths, the cheerleaders' banner is scaled down by a factor of 4.
So, 44 ÷ 4 = 11.
For the perimeter, 156 ÷ 4 is 39.
For the area, you have to do A=bh
(Area = base × height)
The base (length) is 11 inches, multiply that by two to get 22 inches which is the amount for both lengths. If the total perimeter is 39, you have to subtract 22 from that to get the remaining inches which is 17.
17÷2= 8.5 inches. The height is 8.5.
Now you can plug them in
A=bh
A=(11)(8.5)
A=93.5 in^2
The final answer is:
Area = 93.5 in^2
Length = 11 in
Perimeter = 39 in
I hope that helps!
answer:
47
Step-by-step explanation:
258.5/5.5=47
I think there was 17 boys at the beginning of the concert. But i don't know how to put it in terms of P
Given:
Line A: 2x + 2y = 8
Line B: x + y = 4
x = 4 - y
2(4-y) + 2y = 8
8 - 2y + 2y = 0
0 = -8
y = 4 - x
2x + 2(4-x) = 8
2x + 8 - 2x = 8
0 = 0
There is no solution.
