A 100-foot ramp is tilted at a 45° angle. How high is the top of the ramp from the ground?
BabaBlast [244]
Setting up a right triangle, the 100 would be the hypotenuse, the 45 would be the angle of elevation, and you're looking for the opposite side.
Sin 45 = x/100
100sin45 = x
100 * ✓(2)/2 = x
50 ✓2 =x
x = 50✓2 ft

If a square has an area of 196 square feet. what is the perimeter of the sandbox?
IRINA_888 [86]
The area of a rectangular shape is found my multiplying the base x height. Since squares have the same measure all the way around the base must be equal to height so b x h for a square is equal to (b x b)=b^2 or (h x h)^2 they are the same to using b for base we have b^2=196 so sqrt(196) = each side is 14sqft. To find the perimeter we just add all the sides to get (14+14+14+14) or (14*4)= 56sqft.

Elise says, "If you subtract 14 from my number and multiply the difference by - 3, the result is - 63."
Ksivusya [100]
Answer:
35

Explanation:
Let x be equal to Elise’s number.
We can set up our equation like this:

(x-14)(-3)=-63
Expand the parentheses
-3x+42=-63
Subtract both sides by 42
-3x+42-42=-63-42
-3x=-105
Divide both sides by -3
-3x/-3=-105/-3
x=35

I hope this helps!
