Answer:
r=2.9 cm
Step-by-step explanation:
Given:
volume=486π cm^3
height=18 cm
volume of a cone=πr^2h
486=π*r^2*18
486=18π*r^2
486/18=πr^2
27/π=r^2
27/3.14=r
8.5987=r^2
[tex]\sqrt{8.5987[/tex] =r
2.9323 =r
2.9=r(after converting to nearest tenth)

A. $439.20
B. $54.90
C. $133.96
D. $91.50
Answers
Answer:
C. $133.96
Step-by-step explanation:
Convert units:
12 · 0.305 = 3.66 m
8 · 0.305 = 2.44 m
Find the area of the room:
3.66 m · 2.44 m = 8.9304 m²
Find the cost:
8.9304 · 15 = 133.96
12ft = 3.66 sq meters
8ft = 2.44 sq meters
3.66 x 2.44 = 8.9304
8.9304 x 15 = 133.956

A small theater sold 36 adult tickets. The ratio of adults to children was 4:3. How
many child tickets were sold?
Answers
Answer:
27
Step-by-step explanation:
if the theater sold 36 adult tickets and the ratio of adult to children was 4:3, we already know that they sold more adult tickets than children tickets. to turn 36 into 4, we divide 36/4 to get 9, 4*9=36 so we have to do this to the 3, 3*9=27. 36:27 is equal to 4:3.

Answer and Step-by-step explanation:
To find the length of z, we need the lengths of the other 2 sides first. Simply take the square root of both areas and that will be your sides.
[tex]\sqrt{13}[/tex] and [tex]\sqrt{29.25}[/tex]
Now find z, the hypotenuse.
[tex](\sqrt{13}) ^2 + (\sqrt{29.25} )^2 =z^2\\\\13 + 29.25 = z^2\\\\42.25 = z^2\\\\\sqrt{42.25} = z\\\\6.5 = z[/tex]

Answer:
[tex]6\frac{1}{2}[/tex]
Step-by-step explanation:
When given the following problem:
[tex]7\frac{1}{7}-\frac{9}{14}[/tex]
Convert the first mixed number to an improper fraction. This can be done by multiplying the "number" part of the mixed number by the denominator of the fraction, the number under the fraction bar. Then add the result to the numerator.
[tex]\frac{50}{7}-\frac{9}{14}[/tex]
To perform this operation, one must ensure that both denominators have the same value. Multiply the numerator and denominator for the first fraction by (2), so that the denominators of both fractions is (14),
[tex]\frac{100}{14}-\frac{9}{14}[/tex]
Perform the operation, subtract one numerator from the other, leave the denominators the same,
[tex]\frac{91}{14}[/tex]
Simplify, divide the numerator by (14) (the denominator), write the whole part as the "number" part of the mixed number. Then write the remainder on top of the fraction bar.
[tex]6\frac{7}{14}[/tex]
Reduce, divide the numerator and denominator by a common fraction,
[tex]6\frac{1}{2}[/tex]
The answer is 6 1/2
