Answer:
523.59 or 523.60
Step-by-step explanation:
Volume for a sphere: 4/3πr^3 (4÷3x π x r ^ 3)
(r is radius, V is volume)
V= 4/3 x π x r^3
The diameter is 10, so the radius is 5...
V= 4/3 x π x 5^3
V= 4/3 x π x 125
CALCULATER: 4 ÷ 3 x π x 125
Answer 523.59 (523.60 rounded)
Answer:
3
Step-by-step explanation:
to evaluate substitute x = 4 into the rational expression, that is
= 
= 3
Answer:
1. You can tell because every y value divided by its corresponding 3 value is 1/3, except 0 because 0 divided by 0 is 0.
2. Samuel is incorrect because when his sister's age is divided by his age, it differs every year.
(Example: 5/10 ≠ 10/15)
Answer:
Step-by-step explanation:
Angle EFB = 180 - 147 = 33 (Angles on a straight line add up to 180 degrees)
Angle FEB = 180 - 4x (Angles on a straight line add up to 180 degrees)
Since the angles in a triangle add up to 180 degrees ,
Remove brackets:
Add/Subtract:
Subtract 213 from both sides:
Divide both sides by -3:
Answer:
The next term is 54.
Step-by-step explanation:
Look carefully, and you will find that each number increases by 7.
12 + 7 = 19.
19 + 7 = 26.
26 + 7 = 33...
...and so on.
Therefore, the next term is 54 since 47 + 7 = 54.
Hope this helped!
