Answer:
Total earned= $850
Step-by-step explanation:
Giving the following information:
David makes 17 dollars in an hour and works 25 hours each week Linda makes 25 dollars in an hour and works 17 hours.
<u>To calculate the total earned, we need to use the following formula:</u>
Total earned= 17*25 + 25*17
Total earned= $850
3m² = 3 - 8m
0 = 3m² + 8m - 3
0 = (3m - 1 )(m + 3)
m = -3, 0.33
Answer:
20
Step-by-step explanation:
positive not negative
4x - 3y - 7 = 0
-3y = -4x + 7
y = 4/3x - 7/3....slope here is 4/3
A. a parallel line will have the same slope
y = mx + b
slope(m) = 4/3
(-2,1)...x = -2 and y = 1
sub and find b, the y int
1 = 4/3(-2) + b
1 = -8/3 + b
1 + 8/3 = b
3/3 + 8/3 = b
11/3 = b
so ur parallel line is : y = 4/3x + 11/3
B. A perpendicular line will have a negative reciprocal slope. To get the negative reciprocal of a number, u flip the number and change the sign. So our perpendicular line will need a slope of -3/4
y = mx + b
slope(m) = -3/4
(-2,1)...x = -2 and y = 1
sub and find b, the y int
1 = -3/4(-2) + b
1 = 3/2 + b
1 - 3/2 = b
2/2 - 3/2 = b
-1/2 = b
so ur perpendicular equation is : y = -3/4x - 1/2
Answer:
The volume of right circular cylinder is 1540 cubic inches.
Step-by-step explanation:
Diameter of right circular cylinder is 14 inches
Radius of right circular cylinder is 7 inches
Height of cylinder is 10 inches
The volume of any cylindrical shaped object is given by :
So, the volume of right circular cylinder is 1540 cubic inches.
