Answer:

x = 90

Step-by-step explanation:

∠1 = ∠4 ( corresponding angles are congruent ), thus

3x - 160 = x + 20 ( subtract x from both sides )

2x - 160 = 20 ( add 160 to both sides )

2x = 180 ( divide both sides by 2 )

x = 90

Answer:

x = 90.

Step-by-step explanation:

< 1 and < 4 are corresponding angles and are congruent if line  a is parallel to line b. So:

3x - 160 = x + 20

2x = 180

x = 90.

8.) Out of 600 employees, only 270 are happy with their pay. What percent is this? (Please show your work.) *
Gnom [1K]

For this case we can raise a rule of three:

600 employees -------------> 100%

270 employees -------------> x

Where the variable "x" represents the percentage of employees who are satisfied with their salary. So, we have:

x = \frac {270 * 100} {600}\\x = 45

Thus, 45% of employees are satisfied with their salary.

Answer:

45%

lianna [129]

Answer:

D. 108 liters

Step-by-step explanation:

Given that the leak is ;

5 drops = 5 minutes

?= 4 weeks

Find number of hours in 4 weeks

1 week=7days

4 weeks=?--------------cross multiply

4×7=28 days

1 day=24 hours

28 days=?--------------cross multiply

28×24=672 hours

Hour= 60 minutes

672 hours=?

672×60=40320 minutes

Finding the leakage in 4 weeks

80 drops= 5 minutes

?=40320 minutes------------cross multiplication

(40320×80)÷5 =645120 drops

Finding the liters of water wasted in 4 weeks

60 drops of water= 10 milliliters

645120 drops of water=?-------------cross multiply

(645120×10)÷60 =107520 milliliters

But you know

1 milliliter=0.001 liters

107520 milliliters=?-----------cross multiply

107520×0.001

=107.52 liters

=108 liters

Please help i need to get this done asap !
xz_007 [3.2K]

Answer:

Step-by-step explanation:

Equation of line k is   y = (-4/7)x + 1

point (-5,-10); m = -4/7

Line L is perpendicular to k so the perpendicular slope will be 7/4

Equation of line L is  (y - y1) = m(x-x1)

y+10 = (7/4) (x +5)

4y + 40 = 7x + 35

4y = 7x - 5

y = (7/4)x - (5/4)
