Answer:

Therefore, the slope of the red line must be -7

Step-by-step explanation:

If the two lines are said to be perpendicular each other, then the multiplicative of their slope is -1.

Let "m1" be the slope a line and "m2" be the slope of the perpendicular line.

So, m1*m2 = -1

Here, let's take "m1" be the slope of the green line and "m2" be the slope of the red line.

They said to be perpendicular to each other.

So, m1*m2 = -1

Given: m1 = 1/7

NOw plug in m1 = 1/7 in the above statement, we get

1/7 *m2 = -1

Let's find the value of m2, multiply both sides by the reciprocal of 1/7

The reciprocal of 1/7 is 7.

7*1/7*m2 = -1*7

7/7.m2 = -7

m2 = -7

Therefore, the slope of the red line must be -7

Answer:

The charges will be the same after 4 hours.

Step-by-step explanation:

Total Amount = y

Number of hours = x for x > 2

Garage A: y = $7.00 + (x - 2)*3

Garage B: y = 3.25*x

Part 3: What is the cost to be equal?

3.25x = 7 + 3(x - 2) Remove the brackets

3.25x = 7 + 3x - 6 Collect terms on the right

3.25x = 3x + 1 Subtract 3x from both sides.

3.25x - 3x = 3x - 3x + 1 Combine

0.25x = 1 Divide by 0.25

0.25 x/0.25 = 1 / 0.25

x = 4 hours.

One astronomical unit is about 93,000,000 miles. At 20,000 miles per hour how many astronomical units can Orion travel? ( Orion

uranmaximum [27]

Answer:

$2.15\times 10^{-4}\ AU$

Step-by-step explanation:

Given that:-

The speed of the orion= 20,000 miles per hour

Time = 1 hour ( From source )

Thus,

Distance = Speed * Time = 20,000*1 miles = 20,000 miles

Thus, in 1 hour, the orion can travel 20,000 miles

Also,

93,000,000 miles = 1 astronomical unit

1 mile = 1/93,000,000 astronomical unit

20,000 miles = (1/93,000,000)*20,000 astronomical unit

<u>The orion can travel $2.15\times 10^{-4}$ AU in one hour.</u>
