(1) Find radius r:
The area of the circle is:
A = r²π
A = 49π mi²
49π = r²π
49 = r²
r = √49 = 7 mi
(2) Find the surface area of the sphere.
The surface area of the sphere is:
A = 4πr²
r = 7 mi
A = 4π * 7²
A = 4π * 49
A = 196π mi²

Answer:

Step-by-step explanation:
Hello there!
The first thing we want to do is find the least common denominator which would be 20
so we multiply the denominator and numerator of the fractions on the left side by 4
3x4=12
5x4=20 -12/20x
1x4=4
5x4=20 so now we would have

once again we want to isolate the variable using inverse operations
to get rid of the 4/20 we subtract each side by 4/20

now we have

now we want to get rid of the -12/20
to do so we divide each side by -12/20 (or -.6 as a decimal to make it easier)

REMEMBER flip the equality sign
we're left with

Assume that the number of adult tickets is a and the number of child tickets is c.
We are given that the adult ticket is sold for 20$, the child ticket is sold for 10$ and that the total is $15,000. This means that:
20a + 10c = 15,000 ..........> equation I
We are also given that number of child tickets is 3 times that of adult's. This means that:
c = 3a .........> equation II
Substitute with equation II in equation I to get a as follows:
20a + 10c = 15,000
20a + 10(3a) = 15,000
20a + 30a = 15,000
50a = 15,000
a = 300 tickets
Substitute with the value of a in equation II to get c as follows:
c = 3a
c = 3(300)
c = 900 tickets
Based on the above calculations,
number of child tickets = 900 ticket
number of adult tickets = 300 ticket
Answer:
x = 17
Step-by-step explanation:
-1 is the same as minus-ing it by 1.
10 + x - 1 = 26.
10 + 16 - 1 = 25, so it must not be x = 16.
x = 17. lets try it.
10 + 17 - 1 = 26!!
