Answer:

x=25

Step-by-step explanation:

because of vertical angles theorem you set them equal to each other

4x+50=150

subtract 50 from both sides

4x=100

devide by 4 on both sides

x=25

Answer:

x=25

Step-by-step explanation:

180 degrees is half a circle so you subtract 180 from 150 to get 30, that's for both the missing angles. Then you subtract 180 from 30 to get 150 and set 4x+50=150 then solve.

4x+50=150

4x=100

x=25

I beleive 144=2 is the answer.

If you have to divide that to get 1 number it would be 72.

Suppose that profit for a particular product is calculated using the linear equation: Profit = 20S + 3D. Which of the following

uranmaximum [27]

Answer:

b. S = 405, D = 0

Step-by-step explanation:

We have been given that profit for a particular product is calculated using the linear equation: $\text{Profit}=20S+3D$ . We are asked to choose the combinations of S and D that would yield a maximum profit.

To solve our given problem, we will substitute given values of S and D in the profit function one by one.

a. S = 0, D = 0

$\text{Profit}=20S+3D$

$\text{Profit}=20(0)+3(0)$

$\text{Profit}=0$

b. S = 405, D = 0

$\text{Profit}=20S+3D$

$\text{Profit}=20(405)+3(0)$

$\text{Profit}=8100+0$

$\text{Profit}=8100$

c. S = 0, D = 299

$\text{Profit}=20S+3D$

$\text{Profit}=20(0)+3(299)$

$\text{Profit}=0+897$

$\text{Profit}=897$

d. S = 182, D = 145

$\text{Profit}=20S+3D$

$\text{Profit}=20(182)+3(145)$

$\text{Profit}=3640+435$

$\text{Profit}=4075$

Since the combination S = 405, D = 0 gives the maximum profit ($8100), therefore, option 'b' is the correct choice.

Two planes start from los angeles international airport and fly in opposite directions. the second plane starts 1/2 hour after t

mixer [17]

Let x = first plane's speed.
We have the equation:
2 hours * x km/h + 1.5 hours * (x+60) km/h = 3135 km.
3.5 hours*x km/h + 90 km = 3135km
3.5hours*x km/h = 3045km
x = 870 km/h.
The first plane is traveling at 870 km/h, therefore since it is 60 km/h faster, the second plane is traveling at 930 km/h.

PLEASE HELP!! ASAP!!

mr Goodwill [35]

Answer:

D and E

Step-by-step explanation:

A vertical asymptote in this case would mean that the denominator is equal to zero, which is undefined. You can factor the denominator to get you the fraction:

x+2 / (x+6)(x-4) = 0

Then you know that to equal zero, x would have to equal either -6 or 4, which is E and D.
