The length of the other leg to the nearest tenth of a foot is 5.7 feet.
What is Pythagorean theorem?
- A theorem in geometry: the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.
- The Pythagoras theorem equation is expressed as,
, where 'c' = hypotenuse of the right triangle and 'a' and 'b' are the other two legs.
We can use the Pythagorean Theorem to find the length of the other leg
"a" and "c" represent the two legs of the triangle and "b" represents the perpendicular.
So,
= 7² - 4²
b = 
⇒ 5.7 feet
Therefore, the length of the other leg to the nearest tenth of a foot is 5.7 feet.

Answer:
The value of 2 in 2000 is 10 times greater than the value of 2 in 200
Step-by-step explanation:
from the value of 2 in 200 to reach 2000, it takes 10 times as much because we're moving only one place (which is the thousand's digit).
Answer:
3cm
Step-by-step explanation:
V = L * W * H
V = 10 * W * 4
10 * 4 = 40
120 / 40 = 3
W = 3
To attempt this algebraic equation we will be multiplying 4 to (3 - x) bracket so as to form the term on L.H.S.
Combining like terms, we get,
1. Substitute y=-x+2 into x-3y=-18:
x-3(-x+2)=-18,
x+3x-6=-18,
x+3x=-18+6,
4x=-12,
x=-3.
Then y=-(-3)+2=3+2=5.
2. The graphs of two equations you can see in attached diagram. Common point (the point of intersection) represents the solution of the system of two equations.
Answer: (-3,5) or x=-3, y=5.
