Stevie is moving up to the attic and wants to paint a wall white. The wall is a triangle with a base of 20 feet and a height of 21 feet. What is the area of the wall?
Answer:
Step-by-step explanation:
Remark
Use the formula for the Area of a Triangle to find the number of square feet the paint will have to cover.
Formula
Area = 1/2 base * height
Givens
b = 20 feet
h = 21 feet
Solution
Area = 1/2 * 20 * 21
Area = 1/2 * 420
Area = 210 square feet
Which ordered pair is a solution of y = x – 4?
(–3, 7)
(3, –7)
(3, 7)
(–3, –7)
i did this too and i think it was (-3, 7)
Step-by-step explanation:
For each ordered pair, solve the percent problems to find the coordinates. (x is 110% of 10 y% of 50 is 3.5).
Step-by-step explanation:
The value of x and y based on the percentages that are given will be 11 and 7.
How to calculate the percentage
Since x is 110% of 10. This will be;
= 110% × 10
x = 11
Since y% of 50 is 3.5. This will be:
y% × 50 = 3.5
y% = 3.5/50
0.01y = 3.5/50
y = 7
Therefore, it can be seen that value of x and y based on the percentages that are given will be 11 and 7.

The populations of two cities after t years can be modeled by -150t+50,000 and 50t+75,000 . What is the difference in the populations of the cities when t=4 ?
Answer:
The difference in the populations of the cities when t=4 is 25,800.
Step-by-step explanation:
Given equations each of the city:
-150t+50,000
and
50t+75,000
To find the difference between the population when t=4, we first have to solve both equation when t=4.
For both equations, substitute 4 into t:
-150(4) + 50,000 = 49,400
50(4) + 75,000 = 75,200
Now subtract 49,400 from 75,200 and you get 25,800.
The difference in the populations of the cities when t=4 is 25,800.

(-3, -4)
(-4, -5)
(-3, 4)
Please, I need this NOWWWWW
Answer:
focus only on parallel lines which are A and B
angle 5 = angle 6
angle 4 = angle (4x+5)
angle 1 equals angle 3
angle 2 equals angle (3x+7)
notice pattern
look in your notes to see what these angles are called
see pattern?
another pattern......
on same side of parallel lines,
the angles equal same
so angle 3 = angle 6= angle (3x+7)
equals angle (4x+5)
and on left side of parrallel line with intersection ;line,... same concept all same
so if 4x +5 equals 3x+7...... what would be the next step?
stop and think... .... you can solve with those two equations
look above at statement with equals.... what math symbol do you replace with equals? use algebra to solve

15 is 20% of what number?
A.3
B.12
C.30
D.75
Answer:
D.75 is the answer
Step-by-step explanation:
We already have our first value 15 and the second value 20. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
STEP 115 = 20% × Y
STEP 215 =
20
100
× Y
Multiplying both sides by 100 and dividing both sides of the equation by 20 we will arrive at:
STEP 3Y = 15 ×
100
20
STEP 4Y = 15 × 100 ÷ 20
STEP 5Y = 75
Finally, we have found the value of Y which is 75 and that is our answer.
You can easily calculate 15 is 20 percent of what number by using any regular calculator, simply enter 15 × 100 ÷ 20 and you will get your answer which is 75
Answer:
75
Step-by-step explanation:
15 is 20% of What Number?
15 is 20% of What Number? - 15 is 20% of 75. 100% of 75 is 75, therefore 20 percent of 75 equals 15. To learn how to solve 15 is 20 percent of what number, see the step by step instructions below.
15 is 20 Percent of What Number?
75
Formula = Number x 100
Percent = 15 x 100
20 = 75
Following shows the steps on how to derive this formula and find out 20% of what number is 15.
Step 1: If 20% of a number is 15, then what is 100% of that number? Setup the equation.
15
20% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
20Y = 15 x 100
20Y = 1500
Y = 1500
100 = 75
