Question
The two legs of a right triangle are 6 feet and 8 feet long. What is the perimeter of the triangle?
Answer:
<h2>
24 feet</h2>
Step-by-step explanation:
pythagoras theorem
find ipotenuse
√(6²+8²) =
√(36 + 64) =
√100 =
10
find the perimeter (ab + bc + ac)
6 + 8 + 10 = 24 feet
If y varies inversely with x, then we know that:
y = k/x
We are given x and y, so plug in the numbers and solve for k.
1.5 = k/6.4
k = 1.5*6.4
k = 9.6
Answer:
63
Step-by-step explanation:
2 ways: 18/2 = 9 9 times 7 is 63
18 times 3 =54 plus 9 (because 18/2 is 9) is 63
