An SUV costs $27,070 and costs an average of $0.18 per mile to maintain. A hybrid model of the SUV costs $32,880 and costs an average of $0.13 per mile to maintain. After how many miles will the cost of the gas-only SUV exceed the cost of hybrid?

Answers

Answer:

116,200 km

Step-by-step explanation:

Here we have 2 cars, each one with it's corresponding costs. Let's write each cost as functions. The SUV costs $27,070 plus $0.018 per mile. Let x be the miles and SUV (x) the SUV's cost:

SUV(x)=27070+0.18x

We can do the same for the hybrid with a cost function H(x):

H(x)=32880+0.13x

We now need the cost of the SUV to be greater than the hybrid. This is SUV (x)> H(x):

27070+0.18x > 32880+0.13x

Let's subtract 27070 in each side:

0.18 x > 32880 - 27070 + 0.13x

Now let's subtract 0.13x in both sides:

0.05x > 5810

Divide both by 0.05:

x > 5810/0.05

x > 116,200

So, after 116,200km the SUV will turn to be more expensive.

Because the middle point is in the center of the square, the triangle containing angle 2 is isosceles and right (since two sides are equal to half the square's side length), so angle 2 measures (180-90)/2=45 degrees.

remember the pythagorean theorem?
this is like that
the distance is the hypotnuse

D=\sqrt{(x2-x1)^(2)+(y2-y1)^(2)}

D=\sqrt{(8-(-3))^(2)+(-7-4)^(2)}
D=\sqrt{(11)^(2)+(-11)^(2)}
D=√(169+169)

The train at the amusement park is a scale model of a full-size train. A measure of 0.15 meter on the train at the amusement park represents 1 meter on the full-size train. The train at the amusment park is 21 meters long. What is the length of the full-size train in meters

Answers

Answer:

The length of the full-size train is 140 meters.

Step-by-step explanation:

To determine the length of the full-size train, we will use the given relationship between the train at the amusement park and the full-size train.

From the question,

0.15 meter on the train at the amusement park represents 1 meter on the full-size train,

Let the length of the full-size train be x

Now,

If 0.15 meter on the train at the amusement park represents 1 meter on the full-size train

Then, 21 meters on the train at the amusement park will represent x meters on the full-size train

0.15 × x = 21 × 1

0.15x = 21

x = 21/0.15

x = 140 meters

Hence, the length of the full-size train is 140 meters.

Answer:

140m

Step-by-step explanation:

0.15 × x = 21 × 1

0.15x = 21

x = 21/0.15

x = 140 meters
