30 minutes is 1/2 an hour so 16 x 2 = 32 the phone charges at 32% per hour.
1. Multiply the number of hours by the rate and add the original 10% to that for total charge:
Y = 0.32h + 0.10
2. The phone charges at 16% every thirty minutes which is a half hour so you double the rate it charges to get the rate per hour. The phone charges at 32% per hour that it is charging.
It’s the same thing as 5+5+5+5+5+5+5=35
Alright, so you know that the formula for the area of a triangle is a=bh/2
First start out by identifying your base and height.
Base is the side that the shape is "standing on", in this case, that would be 9cm.
Now, the height is the measurement that is perpendicular (90 degrees to the base), which in this case is 12 cm.
Now, plug these values into your formula
(12)(9) /2 = 54 cm squared! hope this helps :)
Answer:
el 50% de 100 es 50 y se calcula multilicando el numero por el porcentaje osea 100×50 y luego se divide el resultado por 100
