pull like terms from the problem to re-arrange it into a product
Answer:
Step-by-step explanation:
a + c = 92.....c = 92 - a
8a + 5c = 688
8a + 5(92 - a) = 688
8a + 460 - 5a = 688
3a = 688 - 460
3a = 228
a= 228/3
a = 76 <==== adults
a + c = 92
76 + c = 92
c = 92 - 76
c = 16 <=== children
If you have an average of 97.2 on your current exam and you get a 99 on your next exam, your average will increase.
- Mean in mathematics is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the total number of values.
- To find the average, sum all the values in the set. Then divide the total by the number of values.
We have the current examination mean, xold = 97.2
Now, we receive, x = 99 on the next examination, the new mean will be:
xnew = (xold + x)/N
xnew = (97.2+99)/2
xnew = 196.2/2
xnew = 98.1
The new average is 98.1
98.1 > 97.2
So if you score 99 on your next exam, your average will increase.

The volume of air the tent encloses will be 157 cubic meters.
<h3>What is the volume of a cone?</h3>
Let r be the radius of the base circle and h be the height of the cone.
Then the volume of the cone will be
V = 1/3 x πr² x h
The base of a conical tent is 5m in radius and the height is 6m.
Then the volume of air does the tent enclose will be
V = 1/3 x π x 5² x 6
V = 1/3 x 3.14 x 25 x 6
V = 157 cubic meters
More about the volume of the cone link is given below.
