Answer:
1. -21
2. 0
3.
Step-by-step explanation:
1. 18 =
multiply both sides by the reciprocal of -6/7.
18 =
-21 = h
-------------------
2.
find the LCM of both fractions.
LCM = 8
multiply both fractions by the LCM
-6x = 21x
subtract 21x from both sides
-6x-21x = 21x-21x
-27x = 0
isolate x
-27x/-27 = 0
x = 0
-------------------
3.
multiply both sides by the reciprocal of -1/2.
z =
hope this helps :)
Combine all x first, dont overthink it
1500 divided by 60 (because 60 is 60 minutes in a hour) equals 25
so there is 25 hours in 1,500 minutes
Answer:
V = 286319.465 cm3
Step-by-step explanation:
First, you have to find the radius to be able to find the volume of a sphere.
The equation for the area of a circle is pi r^2 so you have to so some algebra.
5252 = pi r ^2
5252/pi = r^2
1671.76352 = r^2
sqrt(1671.76352) = r
r = 40.8872048
then you do the equation for the volume of a circle which is 4/3 pi r^3
4/3 pi (40.8872048)^3
4/3 pi 68353.7373
4/3 214739.599
286319.465
V = 286319.465 cm3
Answer:
1.2 should be right but no promises
