Answer:
Find the volume of the sphere.
Either enter an exact answer in terms of π or use 3.14 for π and round your final answer to the nearest hundredth.
The radius is 1
Volume = 
or 4.19
Step-by-step explanation:
Given
Radius, r = 1
Required
Find the volume of sphere
Volume of a sphere is calculated using the following formula
Where V = Volume and r = radius
By Substitution,
Solving further to get the numerical value of volume;
We have to substitute 3.14 for π
V = 4.19 to the nearest hundredth
Answer:
See explanation
Step-by-step explanation:
Jimmy is incorrect.
Using long division, you can find that the real answer.
First, subtract 
from the original expression, leaving you with 
.
Next, subtract 
from the expression, leaving you with 
. Finally, subtract 
from the expression, leaving you with a remainder of 0. This means that the real quotient is 
. Hope this helps!
For this case we must simplify the following expression:
We must add similar terms taking into account that:
- Equal signs are added and the same sign is placed.
- Different signs are subtracted and the major sign is placed.
Thus, the simplified expression is:
Answer:
Answer: She has 76 dimes and 78 quarters.
Step-by-step explanation:
Given data:
Total = $27.20
Solution:
Q = d + 2
Each quarter is 25 cents, or 0.25 of a dollar = 0.25q
Each dime is 10 cents = 0.10d
0.25q+0.10d = $27.20
Where q = d-2
Substitute in this equation:
0.25(d+2)+0.10d = 27.20
0.25d + 0.5 + 0.10d = 27.20
0.35d = 26.7
Divide both sides by 0.35
d = 76
She has 76 dimes and 76 + 2 = 78 quarters.
Solution:
we are given that
A student has some $1 and $5 bills in his wallet.
Let there x $1 bills and y number of $5 bills.
He has a total of 14 bills that are worth $34.
So we can write
Now solve these two equations together using substitution as follows
Hence there are 9 $1 bills and 5 bills are of $5.
