Answer:
A
Step-by-step explanation:
The formula that relates current, power and resistance is

Where
I is the current (in amperes)
P is the power (in watts)
R is the resistance (in ohms)
We know P = 500 and R = 25, we plug them into the formula and solve for I:

Correct answer is 4.47 Amperes, or choice A.
Answer:
it would be a fraction of a sec
Step-by-step explanation:
see if you just simply took out a calculator you would see its not possible unless you knew what the balloon is descending at during the fraction of the seconds
Answer:
The distance between the parallel sides is 20cm.
Step-by-step explanation:
Area of a trapezoid:

where a and b are the 2 bases, and h is the height. The value we're trying to find here is the height.
3 of the 4 variables in this equation are already given:
A = 800
a = 48
b = 32
Just plug those in and solve for h:

9 is the answer
