Answer:
B
Step-by-step explanation:
f(x) = 4x - 7
What does f(x) mean? It means that whatever variable you have on the left which is (x), the same variable must be on the right.
So f(2) means that whatever variable is on the right, it must be replaced with 2 on the right. So .....
f(2) = 4(2) - 7
f(2) = 8 - 7
f(2) = 1
The area of the pond is
Area = l * w
Area = 50 * 50
Area = 2500 square meters.
Then there is a sidewalk with 5 meters wide around the pond.
So the new dimension is
60 * 60
Area = 60 * 60
Area = 3600
Then at 45 m^2 = $74
= 3600 / 45 * 74
= $5,920
So the total cost of tile is $5,920.
Answer:
The measure of smaller angle = 45°
Step-by-step explanation:
Finding the unknown angle
Ratio of the supplementary angles = 3 :1
The angles are 3x , x
Supplementary angles add up to 180°
3x + x = 180
4x = 180
x = 180 ÷ 4
x = 45°
3x = 3*45 = 135°
One adult ticket costs 43 dollars what I did was 104.50 - 18.50 and divided that answer by 2.
He will receive $13.70.
You would have to multiply 2.25 by 2.80 to get 6.30, which is the total cost due. Subtract 6.30 from 20 to get your answer, 13.70, or the change Mr. Stein will receive.
