Answer:
Step-by-step explanation:
Well first we need to add the tip in order to find the total amount of cash needed to be paid.
0.3696 x 20 = 7.392
So lets just say $7.39
Add that to the sub total which is 36.96
36.96 + 7.39 = $44.35
Now, in order to figure out how much each friend should pay, we divide the total by 4.
44.35/4 = 11.0875
So lets just say $11.09
So each friend should pay about $11.09
Answer:
14.8 units³
Step-by-step explanation:
The volume of a "pointed" solid, such as a cone or pyramid, is one-third the product of its base area and height:
V = (1/3)Bh
Filling in the given numbers and doing the arithmetic, we find the volume to be ...
V = (1/3)(7.4 units²)(6 units) = 14.8 units³
The volume of the pyramid is 14.8 cubic units.
Answer:
The correct answer is:
(a) Mean = 170,

Always use PEMDAS as order of operations:
parentheses before exponents before multiplication before division before addition before subtraction = P.E.M.D.A.S.
Since we have only addition, subtraction, multiplication, and division, we need to do:
M>D>A>S
5 + 5 - 2 * 7 / 8 + 98 - 64
5 + 5 + [-2 * 7] / 8 + 98 - 64. first
5 + 5 + [-14 / 8] + 98 - 64. second
(10) + [-1.75 + 98] - 64. third
[10 + 96.25] - 64. fourth
106.25 - 64. last
42.25
