Mathematics

Nimfa-mama [501]3 years ago

Remember you can do anything to an equation as long as you do it to both sides
a=age

500 reduced by 2 times a is equal to 388

500-2a=388
minus 500 both sides
-2a=-112
divide both sides by -2
a=56

you are 56

Ella takes 1 3/5 hours to complete a painting. Holly takes 3/4 of the time that Ella takes. How long will Holly take to complete
Misha Larkins [42]
1. you have to figure out what 3/4 of Ella's time is.
1 \frac{3}{5}  =  \frac{8}{5}
(You find that out by multiplying 5x1. Then add 3.)
2. Convert the fractions into decimals. (This will help make it easier when dividing.)
\frac{8}{5}  = 8 \div 5 = 1.6
\frac{3}{4}  = 3 \div 4 = .75
3. Next you are going to divide 1.6 by .75
1.6 \div .75 = 2.13
4. Now multiple 2.13 by 5.
2.13 \times 5 = 10.65

Change 225° to radian measure in terms of pi​
a_sh-v [17]

Answer:

\frac{5\pi }{4}

Step-by-step explanation:

To convert from degree to radian measure

radian measure = degree measure × \frac{\pi }{180}

Hence

radian measure = 225 × \frac{\pi }{180} = \frac{225\pi }{180} = \frac{5\pi }{4}
