You can multiply each fraction on both top and bottom so that they have 24 as the denominator. The equation becomes
![\frac{20}{24} m- \frac{10}{24} = \frac{21}{24} m+ \frac{16}{24}](https://tex.z-dn.net/?f=%20%5Cfrac%7B20%7D%7B24%7D%20m-%20%5Cfrac%7B10%7D%7B24%7D%20%3D%20%5Cfrac%7B21%7D%7B24%7D%20m%2B%20%5Cfrac%7B16%7D%7B24%7D%20)
subtract 16/24 to both sides and you get
![\frac{20}{24} m- \frac{26}{24} = \frac{21}{24} m](https://tex.z-dn.net/?f=%20%5Cfrac%7B20%7D%7B24%7D%20m-%20%5Cfrac%7B26%7D%7B24%7D%20%3D%20%5Cfrac%7B21%7D%7B24%7D%20m%20)
now subtract 20/24 from both sides and
![\frac{-26}{24} = \frac{21}{24} m](https://tex.z-dn.net/?f=%20%5Cfrac%7B-26%7D%7B24%7D%20%3D%20%5Cfrac%7B21%7D%7B24%7D%20m)
<u />
multiply 24 on both sides
-26=21m
and divide by 21 on both sides
m=-26/21 or -1.24
Answer:
14 mi
Step-by-step explanation:
V = 718.38 mi³, r = 7 mi, find h
Use V = πr²h/3
718.38 = 3.14 * 7² * h/3
718.38 = 51.287 h
h = 718.38/51.287 = 14 mi
Answer:
1250
Step-by-step explanation:
?/5000 = 25/100 5,000x25= 125,000 divided by 100= 1250.00= 1250
The approximate distance that Sabrina traveled in one revolution of the Ferris Wheel is A).45,972.74ft
Answer:
27mi
Step-by-step explanation:
Since the sailing course is equilateral in shape, then all their sides are equal.
Get one of the sides using Pythagoras theorem as shown;
Let one of the side be x
Two base will be x/2
According to the theorem;
x² = 9² +(x/2)²
x² = 81 + x²/4
x²-x²/4 = 81
3x²/4 = 81
3x² = 324
x² = 324/4
x² = 81
x = 9
Perimeter of the triangle = 3x
Perimeter of the triangle = 3(9)
Perimeter of the triangle = 27mi
