You must convert the percentage to decimal notation and then multiply it by 72.
As the name implies, percentage is a something per one-hundred; so to convert any percentage to decimal notation we divide by one-hundred:
So the 310% of 72 is:
Answer: a
Step-by-step explanation: edge 2020
Answer:
D
Step-by-step explanation:
5 (x + 6) = 45
Multiply 5 by what's in parenthesis.
5 times x = 5x ** use the + sign ** 5 times 6 = 30
5x + 30 = 45
Answer:
The profit margin for the concert sponsorship is 31.3725 %
Step-by-step explanation:
An arena receives for 1 event = $1700
An arena receives for 12 events =
An arena receives for 12 events = 20400
The costs for this sponsorship total $14,000
Profit = 20400-14000
Profit =6400
Profit margin =
Profit margin =
Hence the profit margin for the concert sponsorship is 31.3725 %
Answer:
48 ft
Step-by-step explanation:
Here, we want to find the length of the wire
from the diagram, we can identify two similar triangles
The smaller one and a bigger one
Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal
We can start by getting the height of the tower
we have this as:
8/11 = 28/x
8 * x = 28 * 11
8x = 308
x = 308/8
x = 38.5 ft
So as we can see, the wire represents the hypotenuse of the larger triangle that measures 28 ft base and 38.5 ft height
So we can use the Pythagoras’ theorem to get the hypotenuse
Let us call this g
mathematically according to the theorem, the square of the hypotenuse equals the sum of the squares of the two other sides
thus, we have it that;
g^2 = 38.5^2 + 28^2
g^2 = 2,266.25
g = √2,266.25
g = 47.61 which is approximately 48 ft
