Answer:
3940.5 cm^3 to the nearest tenth.
Step-by-step explanation:
The radius = 1/2 * diameter = 9.8 cm
Volume V = 4/3 *3.14 * 9.8^3
= 3940.457.
Answer:
-8 or -1
Step-by-step explanation:
x*2+9x+8=0
(x+8)(x+1)=0
x+8=0 or x+1=0
x= -8 or x= -1
5(x + 10) + x
First, expand. / Your problem should look like: 5x + 50 + x
Second, gather like terms. / Your problem should look like: (5x + x) + 50
Third, simplify. / Your problem should look like: 6x + 50
Answer: 6x + 50 (C)
Answer:
123
Step-by-step explanation:
Answer:

Step-by-step explanation:
An irrational number can't be written as a simple fraction or ratio.
Therefore, the expressions 8/5,
, and
are rational.
Why?
This is because 8/5 = 1.6,
= 2, and
= 8. Since all of the expressions can be simplified to set numbers (that can then be converted to fractions or ratios) the answer is
.
