A store has 7 red shirts, 15 black shirts, 13 white shirts, and 5 green shirts. Select the
portion of the shirts that are black
1. Make a fraction for what you are looking for (Black
shirts/total)
2 Simplify

First you have to add all of the shirts together, which gives you: 40

Since 15 of those are black, then you need to put those 15 over the total number of 40, making it 15/40.

Then you must simplify by the highest number that will go into both, and since that number is 5, it will then go into 15 three times and it will go into 40 eight times.

That leaves you with the answer of: 3/8

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

current in the circuit at time t is /, then the power delivered to the resistor is
