Because cars use oil and oil is a fossil fuel. And when you drive the engine heats up which make the smoke come out of the exhaust pipe and it gets into the air and pollutes which is dangerous for any creature that flies.
Answer:
Full question is attached.
Tommy's reasoning is wrong because the hypotenuse is not 5 feet.
A skateboard ramp resembles a right angles triangle so its sides resemble that of a right angled triangle.
The height of 3 feet would be the height of the triangle.
The length of 5 feet would be the length of the triangle.
The piece of plywood that would cover the top of the frame would be the hypotenuse.
In using the Pythagoras rule, the c is the hypotenuse but Tommy made the mistake of assuming that the hypotenuse was b which is where the error came from.
Instead of solving for b, they should have been solving for c which is the hypotenuse.
a² + b² = c²
3² + 5² = c²
9 + 25 = c²
c² = 34
c = √34
c = 5.83 feet
They should use a plywood of 5.83 feet not 4 feet.
Answer:
<h2><u>
FALSE</u></h2>
Explanation:
Hurricanes only form in the western hemisphere
Typhoons only form in the eastern hemisphere

Answer:
The most appropriate choice on the set of Brighton Beach Memoirs to indicate that the play takes place in 1937 would be:
a black-and-white photograph of the New York Yankees
Explanation:
To understand this answer we need to evaluate the rest of them. First of all, none of them would be black and white in an era of black and white pictures. Second, the pitcher filled with lemonade would not indicate the time. Third, the wood-burning stove would be from an earlier time and the color television would be from a more recent time, also both would not match their own time. Therefore, the picture is the correct answer.
Since this is a square you can set 3x+20=5x then you can solve for x.
Subtract 3x from both sides:
3x-3x+20=5x-3x
20=2x
Divide both sides by 2
20/2=2x/2
10=x
Hope this helps.
