Select the correct answer. The formula for the voltage, V, of an electrical current is V=√pr, where P is the power measured in watts and R is the resistance measured in ohms.

A toy train with a resistance of 10 ohms is powered by four 1.5-volt batteries. What is the power of the toy train?
( ALL I KNOW IS THAT ITS NOT B )
A.
16.7 watts
B.
0.60 watts
C.
0.225 watts
D.
3.6 watts

D

Step-by-step explanation:

Given

V = ← substitute V = 4 × 1.5 = 6 and r = 10

6 = ( square both sides )

6² = 10p

36 = 10p ( divide both sides by 10 )

3.6 = p

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
