Answer:
800
Step-by-step explanation:
160 * 100% / 20% = 800
If 20% of a number is 160 then the original number is 800.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that 20% of number is 160
We need to find the original number.
Let the original number be x
Convert 20% to decimal value by dividing 20 with 100
20/100=0.2
Now multiply 0.2 with x which is equal to 160
0.2x=160
Divide both sides by 0.2
x=800
Hence, If 20% of a number is 160 then the original number is 800.

Answer:
II) 78
Step-by-step explanation:
2x - 6 + 7x + 15 = 90
9x + 9 = 90
9x = 81
x = 9
<ABC:
7x + 15
7(9) + 15
78
Answer and Step-by-step explanation:
To find the measure of angle ABC, we need to find what x is first. We accomplish this by adding together the two angles and setting it equal to 90.
2x - 6 + 7x + 15 = 90
Combine like terms.
9x + 9 = 90
Subtract 9 from both sides.
9x = 81
Divide both sides by 9.
x = 9
We get x to be 9.
Now, we can plug this in for angle ABC.
7(9) + 15
Multiply 7 and 9 together.
63 + 15
Add 63 and 15 together.
78
The measure of ABC is 78.
That means the answer is II) 78.

2. Find the unit rate demonstrated in the graph
below.
A. 9 miles per hour
B. 4.5 miles per hour
C. 3 miles per hour
D. 1.5 miles per hour
The unit rate of demonstrated in the graph will be 4.5 miles per hour. Then the correct option is B.
What is the rate?The rate is the proportion of how much something is to the unit. For instance - Assuming that the speed of the vehicle is 20 km/h it implies the vehicle voyages 20 km in 60 minutes.
The incline is the proportion of rising or falling and running. The contrast between the ordinate is called rise or fall and the distinction between the abscissa is called run.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
From the graph, take two points from the graph which are (0, 0) and (27, 6).
Then the unit rate demonstrated in the graph will be given as,
Rate = (27 - 0) / (6 - 0)
Rate = 27 / 6
Rate = 4.5 miles per hour
The unit rate of demonstrated in the graph will be 4.5 miles per hour. Then the correct option is B.

2(x - 1)(x + 1) = 5x
Answer:
x = sqrt 5x - 2/2
Step-by-step explanation:
2(x-1)(x+1) = 5x
2(x^2 - 1) = 5x
2x^2 - 2 = 5x
2x^2 = 5x - 2
2x = sqrt 5x - 2
x = sqrt 5x - 2/2

Answer:
Average rate of change = 1
Step-by-step explanation:
Average rate of change of a function between x = a and x = b is defined by,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
We have to find the average rate of change of the function in the interval 2 ≤ x ≤ 4
Therefore, average rate of change of the function = [tex]\frac{f(4) - f(2)}{4-2}[/tex]
From the graph attached,
f(4) = 4
f(2) = 2
Average rate of change = [tex]\frac{4-2}{4-2}[/tex]
= 1
Therefore, average rate of change of the function in the given interval is 1.
This trapezoid-based right prism has a volume of 30 cm^3, 6cm ,5 cm, 1 cm what is the area base?

Joe buys 6 adult tickets and 4 child tickets for the movies. Each adult ticket cost $9. Each child ticket cost the same amount. Joe pays with a $100 bill and gets $22 in change. How much does each child ticket cost?
Answer:
Each child ticket cost = $6
Step-by-step explanation:
Joe has = $100
His balance after tickets purchase = $22
Actual amount spent on tickets = $100 - $22 = $78
But,
Each adult ticket cost = $9
Total no of adult = 6
Total amount spent (adults) = $9 x 6 = $54
Balance remaining = $78 - $54 = $24
Amount spent of 4 child tickets = $24
No of children = 4
Therefore,
Amount spent on 1 child (1 ticket),
= $24/4 = $6.
It could be seen that each child ticket cost six dollars.
