Answer:the width is 5 1/4 ft
Step-by-step explanation:
Step 1
The area of a rectangle is given as Length x width
Therefore the area of the rectangular board = Length x width
The length of the first board =6ft
The length of the second board =5 1/2 ft (5.5ft) with both having a total area of 60 3/8 (60.375ft²). To find the width of the boards since both have equal width, we use the equation
Length x width of board A + Length x width of board B= area of board A and Board B
6w + 5.5w =60.375
Step 2---- Solving the equation
6w + 5.5w =60.375
11.5w = 60.375
w = 60.375/11.5
w= 5.25
Therefore the width of the two boards are 5.25 ft / 5 and 1/4 ft each
Answer:
Speed before applying brakes = 64.8
Step-by-step explanation:
The formula is given as:
Where
s is speed of car, and
d is length of skid marks
It is given that d = 175 ft, so we substitute and find the speed of the car before the brakes were applied.
Rounding to nearest tenth, that is 64.8
8x=20
x=2.5
To check
8(2.5)=20
