Find the slope for the two lines and state that they are equal (condition for parallel lines)
Slope of line AB
[y2 - y1] / [x2 - x1]
Slope of line CD
[y4 - y3] / [x4 - x3]
Condition
[y2 - y1] / [x2 - x1] = [y4 - y3] / [x4 - x3]
Step-by-step explanation:
part A
all listed features (A - F) are correct and to be selected.
part B
the average rate of change is
(f(x2) - f(x1)) / (x2 - x1)
so,
(f(0) - f(-2)) / (0 - -2) = (2 - 0) / (0 + 2) = 2/2 = 1
FInd the circumference of the tire:
C = 2 x PI x r
C = 2 x 3.14 x 14
C = 87.92 inches.
For every revolution of the tire it travels 87.92 inches.
In one minutes the car travels 87.92 x 120 = 10,550.4 inches.
In 5 minutes the car travels 10550.4 x 5 = 52,752 inches.
52,752 / 12 = 4,396 feet
1 mile = 5280 feet
4396 / 5280 = 0.833 miles
I calculated 3 different measurements. Use the one needed.
Answer: 50
Step-by-step explanation:
7/10 can of cola= 1 glass.
35 cans of Sola= y
7/10 equals 0.7 as decimal
0.7 = 1
35 = y
Cross multiply
0.7y = 35
Divide both side by 0.7
y = 35/0.7
= 50
50 glasses will be filled
Part A) $520
Part B) 13.33% - Divide 520 by 39
Part C) $20.80 Divide 520 by 100, then multiply by 4
