You have to do the reverse operation to 57 so you have to do 57÷3 which is 19

What percent of 72 is 48 with step by step process
Sedaia [141]

Answer:

67%

Step-by-step explanation:

There are a few methods to finding the percent of a number.  You can use proportions:

\frac{percent}{100}=\frac{48}{72}

The 'percent' is the percent of the fraction that you are looking for, or 48/72.

Cross-multiply:  72x = (48)(100) or 72x = 4800

Divide both sides by 72:  72x/72 = 4800/72

Solve for 'x':  x = 66.6666...

Round 66.666.... to the nearest percent: 67%

I NEED HELP!!! ASAP!!!!
Daniel [21]

I hope this helps you

at the 30-60-90 triangle has rules

30=>k

60=>k(square root of) 3

90=>2k

so in this triangle 60=> see 9

k(square root of) 3=9

k=9/(square root of) 3

2k=18/(square root of) 3

at the 45-45-90 triangle rules are

45=>2k

45=>2k

90=>[2k/(square root of 3)] (square root of) 2

x=[18/(square root of 3)].(square root of 2)

x=18(square root of 2)/square root of 3
