when the first decimal number is 4 or below, then you leave the whole number as it is, and get rid of the decimals.
PRQ and QRS should add to PRS
(3x-8)+(2x+6)=98
5x-2=98
5x=100
x=20
Plug 20 into both expressions:
3(20)-8
60-8
52 degrees= PRQ. <===========
2(20)+6
40+6
46 degrees= QRS. <==========
When you divide powers, you subtract them.
12-3=9
B. 5^9 is the answer.
I hope this helps!

Answer:
4.5 hours
Step-by-step explanation:
t=d/r
315/70=4.5
Answer:
Okay well first we right down what we already know:
- volume of 2,355 cubic inches
- the height is 10 inches
Now we write down the equation for the volume of a cone:
V = πr²
lets plug in what we know into the equation
2,355 = πr²
now we simplify to solve for r
2,355 / 10/3 = 706.5 = πr²
706.5/π = r²= 224.89
now since its r² we take the square root of 224.89
r = 15 inches
for diameter we multiply 15 by 2
diameter = 30 inches
