Answer:
Step-by-step explanation:
Angle 1 = 8x + 45
Angle 2 = x
x + 8x + 45 = 180
combine like terms
9x + 45 = 180
subtract 45 from both sides
9x = 135
divide both sides by 9 to isolate x
x = 15
Angle 1 = 8(15) + 45 = 165 degrees
Angle 2 = 15 degrees
Step 
we know that
The density's formula is equal to
The volume of a cone is equal to
where
r is the radius of the base of the cone
h is the height of the cone
in this problem
substitute the values in the formula above
Step 
Find the density
we have
substitute in the formula
therefore
<u>the answer is</u>
the density is 
Answer:
Raven should buy the boots at LaceUp since total cost is lower ($77.54)
Step-by-step explanation:
price of the boots at Shoe Town:
[$85.95 x (1 - 15%)] x (1 + 7.16%) = $73.06 x 1.0716 = $78.29
price of the boots at LaceUp:
{[$85.95 x (1 - 10%)] - $5} x (1 + 7.16%) = ($77.36 - $5) x 1.0716 = $72.36 x 1.0716 = $77.54
price of the boots at Run, Don't Walk (online store):
$71.99 + $6.50 = $78.49
Are you supposed to estimate or get an exact answer? If you're estimating you can see if the number is close to any perfect squares. In this case 63 is very close to 64, and 48 is very close to 49. The answers can then be estimated to be approximately 8 and 7, respectively.
