Answer:
1/45 = 0.02
4/35 =0.1 142857
Step-by-step explanation:
A² + b² = c²
8² + x² = 16²
x² = 16² - 8²
x² = 192
x =√192
x =8√3
12 inches equals (or :1) foot; the ratio of inches to feet is 12 inches to one foot 24 inches; the ratio of feet to inches is 2:24. 6 feet equals 2 yards; the ratio of feet to yards is 6:3. 1 yard equals 3 feet; the ratio of yards to feet is 1:3

Answer:
The dimension of the rectangular closet before construction = (x + 5) ft by (x + 4) ft
Step-by-step explanation:
The homeowner has a rectangular closet and the area of the closet is (x² + 9x + 20) ft². The area of a rectangle is the length multiplied by the width. The length is given as (x + 5) ft. After construction the area change to (x² + 14x + 48) ft². The length became (x + 6) ft.
The dimensions before construction can be calculated as follows:
Mathematically,
area of rectangle = Length × width
area = (x² + 9x + 20) ft².
Length = (x + 5) ft
Width = unknown
area = LW
(x² + 9x + 20) = (x + 5) W
W = (x² + 9x + 20) / x + 5
W = (x + 4) ft
The dimension of the rectangular closet before construction = (x + 5) ft by (x + 4) ft
Answer:
x =0 , y=7
Step-by-step explanation:
12x + 3(-4x+7) = 21
12x - 12x + 21 = 21
21 = 21
0=21-21
0=0
therefore x = 0
12(0)+3y =21
3y =21
3y/3=21/3
y=7
