Answer:
b
Step-by-step explanation:
The legs are 5 inches long.
Use the Pythagorean theorem:

The length of the hypotenuse of the triangle is approximately 7 inches long.
Answer: It depends on which variable you're solving for.
Step-by-step explanation:
Solving for b: b=7/8mx + -1/8xy
Solving for m: m=xy+8b
______
7x
Solving for x: x=-8b
___
-7m+y
Solving for y: y=7mx-8b
______
x
Answer:
Step-by-step explanation:
let, the length is z
thus the ratio will be 5z : 4z
perimeter = 2 (a + b)
360 = 2 ( 5z + 4z )
180 = 9z
z = 20 cm
length = 100 cm and width = 80cm
area = length * width
area = 100*80
area = 8000cm²
Answer:
a. True
b. True
c. False
d. False
Step-by-step explanation:
<u>First Table</u>
Length=10 feet, Width=4 feet
Area =10 X 4=40 Square Feet
<u>Second Table</u>
The second table is half as long as the first table.
Length =0.5 X 10 =5 feet
Area=5 X Width= 5w
The area of the second table is one fourth the area of the first table.
Area of Second Table =
X Area of first table
5w=
X 40
5w=10
Width of the Second table, w=2 feet
The following are true.
(a)The width of the second table is 2 feet.
(b) The area of the second table is 10 square feet.
