Each line represents a technician. So if you want to know at what time the charges are equal, you need to see where the lines intersect. In this case, its 2.5 hours.

Wittaler [7]

Answer:

New price of the stock = $42

Step-by-step explanation:

Given

Price of stock at the start of the day = $35

Increased by 20% by the end of the day.

To find the new price of the stock which is the price of the stock at the end of the day.

Solution:

Price at start =$35

Increase Percent at the end = 20%

Amount of increase in price = Increase\ percent \times start\ price = 20\% \times 35 =0.2\times 35=\$7.0

∴ New price at the end of the day = Start\ price + increase\ in\ price= \$35+\$7=\$42

An airplane flies 810 km in 1.5 hours. How far will the plane fly into. Two hours if it maintains the same airspeed
nadezda [96]

It would help to first find the unit rate. We know that the plane flies 810 km per 1.5 hours. Divide by 1.5 on both sides:

810/1.5 = 540 km/hour

Then, multiply both the hour and the distance by 2:

540 * 2 = 1080 km/2 hours.

I JUST NEED 2. ANSWERED! THIS IS DUE! Solve for x
8_murik_8 [283]

Answer:

x=24

Step-by-step explanation:

Since line A and B are parallel, 3x+7 is equivalent to Angle 6 as they are corresponding angles.

We also know that 4x+5+Angle 6 = 180 as they are a linear pair. We can use substitution and substitute 3x+7 for Angle 6...

4x+5+3x+7=180

7x+12=180

7x=168

x=24

Find the midpoint of the line segment that has endpoints at (10,8) (-3,-10)
dem82 [27]

Hey there! :)

Answer:

(3.5, -1).

Step-by-step explanation:

Use the midpoint formula to solve this problem:

(x_m, y_m) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

Plug in the coordinates given:

(\frac{10-3}{2}, \frac{8-10}{2})

Simplify:

(\frac{7}{2}, \frac{-2}{2})

Therefore, the coordinates of the mid-point are:

(3.5, -1).
