= 33.9F is the correct answer
Answer:
1: r = 2.4 cm
2: V = 57.8765 cm^3
Step-by-step explanation:
1:
The volume of a sphere is given by V = (4/3) * pi * (r^3), being 'r' its radius.
So if the volume is 463.01 cm^3, we have that:
463.01 = (4/3) * pi * (r^3)
463.01 * 3 = 4 * 3.14 * r^3
r^3 = 463.01 * 3 / (4 * 3.14) = 110.59156
r = 4.8 cm
2:
The radius of the second sphere is 4.8/2 = 2.4 cm, so its volume is:
V = (4/3) * 3.14 * (2.4^3) = 57.8765 cm^3
Answer:
$31.55
Step-by-step explanation:
She earns $25.75 one week and $37.80 another week that means she earned $25.75 + $37.80 = $63.55 in total
She spent $32 therefore she has $63.55 - $32 = $31.55 left
The answer would be 340 and its correct because I did it!!
Answer:
Step-by-step explanation:
All the angles in a triangle have to add up to 180 degrees.
#17.)
45+50=95
180-95=85
x=85
#18.)
This one is a little different. The furthest two angles are complimentary which means that they add up to 180 degrees (a straight line.) Once you find the missing angle to that one, you can do the same thing as you did in #17.
180-118=62.
25+62=87
180-87=93
x=93
#21.)
For this one a slightly larger equation is needed. Since we don't have a definite number for the bottom left angle, we have to use x+2 as our number. We first have to find the bottom right angle though.
180-108=72
x+x+2+72=180
2x+74=180
2x=106
x=53
