Converting 200 miles to the amount of carbon dioxide emission that would be 1.884 tons annually. This will be the amount of carbon dioxide given that 200 miles is monthly covered.

Answer:

Carbon dioxide emitted in the atmosphere is 129.6 kg.

Step-by-step explanation:

As we know when we burn 1 gallon of gasoline produces 20 pounds of carbon dioxide.

Since in i gallon a truck covers 14 miles which means in 14 miles a truck produces 20 pounds of carbon dioxide gas.

Now we can calculate the amount of CO2 emitted by a truck in 200 miles.

∵ During 14 miles CO2 emitted = 20 pounds

∴ during 1 mile CO2 emitted will be = 20/14 pounds

∴ While covering 200 miles CO2 emitted = (200×20)/14 = 285.71 pounds of CO2.

Or by converting 281.71 pounds to kg amount of CO2 will be = 129.6 kg

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs ​$77. A season ski pass costs ​$450. The
n200080 [17]

Answer:

5

Step-by-step explanation:

Given:

  • Daily pass = $77
  • Season ski pass = $450
  • Skis = 20

77 + 20 = 97

450 + 20 = 470

Keep multiplying 97 with random numbers until it passes 470.

97 × 4 = 388

97 × 5 = 485

So, the skier will have to pay daily passes 5 times to be more expensive than the season pass.

Hope this helped.

Rectangle KLMN is graphed on the coordinate plane below. On a coordinate plane, rectangle K L M N has points (2, negative 2), (5
gladu [14]

Answer:  The correct option is (A) (2, -2).

Step-by-step explanation:  Given that rectangle with vertices at K, L, M and N is graphed on the coordinate plane as shown in the figure.The figure is rotated 360° counterclockwise using the origin as the center of rotation.

We are to find the location of the image of point K after the rotation.

We know that

a rotation of 360° in counterclockwise direction about the origin map a point to itself. That is, the co-ordinates of the image point will be same as the original one.

From the figure, we see that the co-ordinates of point K are (2, -2).

Therefore, after rotation of 360° counterclockwise using the origin as the center of rotation,

the co-ordinates of the image of point K will also be (2, -2).

Thus, the location of the image of point K is (2, -2).

Option (A) is CORRECT.
