This is I suppose basic addition. Addition is a mathematical process of combining or joining something to something else. The word "total" indicates that the addition will be used. If the doctor ran for 55 hours and the mom for 52 hours, by using the addition it will be:
55
+ 52
______
107 hours in total.
107 hours converted in days will be 4 days and 4 hours. SInce 1 day contains 24 hours you now divide 107 hours by 24 hours to get its equivalent to days.
For this case we have by definition, that the volume of a cone is given by:

Where:
A: It is the cone radius
h: It's the height
They tell us that the diameter is 21 m, then the radius is half the diameter, that is: 10.5m. The height is 4m. Substituting the data:
.
Finally, the volume of the cube is
ANswer:
Option B
If 1295 × p = 714, then you can rearrange the equation to find the percentage.
You have to get p on its own, so you divide 1295 on both sides of the '='.
1295 × p = 714
p = 714 ÷ 1295
p = <span>0.55135135135...
p </span>× 100 = actual percentage
actual percentage = 55.14%
When written as the quotient of two integers,
0.69696969 = <em>69,696,969 / 100,000,000 .</em>
<u>If</u> you had said that the ' 69 ' keeps repeating forever and never ends,
then that decimal would represent the fraction
23 / 33 .
Tan 60 in radical for is square root of 3
