AB = √(8^2 + 6^2)
AB = √100
AB = 10
AC = √(8^2 + 15^2)
AC = √289
AC = 17
BC = 9
P= AB + AC + BC
P = 10 + 17 + 9
P = 36 units
34)
Area of ABC = 1/2 x 8 x 9
A = 36 square units
Answer:
12 cm
Step-by-step explanation:
x/36=5/15
x=36/3
x=12 cm
{2×[20×5]+68} could be your answer because 20×5 is 100 and 2×100 is 200. 200+68 is 268
This uses the concept of proportions.
.002 converted to a fraction is 2/1000, or 1/500.
We set up the proportion like so:
10/100 = .002/x
Solve for x.
Cross-multiply.
10 * x = .002 * 100
10 * x = .2
x = .2 / 10
x = .02
The answer is .02
