Answer:
Step-by-step explanation:
1. take 10 times a and get 10a and put in the numerator spot of your answer
2. then do 15 times 20 which is 300 so add 300 to 10a in the numerator spot of your answer
3. multiple 20 times 10 which is 200 and make it your denominator of your answer
This method is called the butterfly method
Answer:
There is 48 inches in 4 feet.
Step-by-step explanation:
If there is 12 inches in every foot. That means you have to multiply 12 inches by 4. I hope this helps.
Set this up like a right triangle with the height of the triangle as 30, the angle across from that side, the reference angle, as 55, and the base is your unknown, x. This means that we have the angle, the side across from it, and the side adjacent to it. That sounds like the tangent ratio to me! Tangent of the angle is the side opposite over the side adjacent:
. Solving for x:
. Do that on your calculator in degree mode to get that the distance between the base of the ladder and the wall is 21 feet
To solve this problem you first get the area of the plywood that is 4' by 8'
4 * 8 = 32
Next you get the area of the pieces, which is 1' by 2'
1 * 2 = 2
Next you see how many pieces will go into the whole plywood.
32 / 2 = 16
So she can make 16 signs.
In the real world this would not be possible because you have to take in the fact the saw blade thickness which cuts the wood and takes a little bit of the wood away per cut but for Acadima this will suffice.
If the lines are parallel, they have no solutions because they never touch
