carpenter has a board that is 8 feet long. e cuts off two pieces. One piece is 32 feet ug and the other is 2 feet long. How ch of the board is left?
Answer:
2 1/6 feet
Step-by-step explanation:
A carpenter has a board that is 8 feet long. He cuts off two pieces. One piece is 3 1/2 feet long and the other is 2 1/3 feet long. How much of the board is left?
Total length of the board = 8 feet
Piece A = 3 1/2 feet
Piece B = 2 1/3 feet
Piece A + piece B
= 3 1/2 feet + 2 1/3 feet
= 7/2 + 7/3
= (21+14) / 6
= 35/6
= 5 5/6 feet
Length of the board remaining = Total length of the board - length of the two pieces
= 8 feet - 35/6 feet
= (48-35) / 6
= 13/6 feet
= 2 1/6 feet
Length of the board remaining = 2 1/6 feet

In ΔPQR, the measure of ∠R=90°, the measure of ∠P=26°, and PQ = 8.5 feet. Find the length of QR to the nearest tenth of a foot.
Answer:
3.7feet
Step-by-step explanations
Using the sin rule
A/sin a = B/sin b
Let A = PQ = 8.5feet
B = QR = x feet
a = R = 90°
b = P = 26°
Substitute the values into the Sin rule
8.5/sin90 = x/sin26
8.5×sin 26 = x × sin 90
8.5×0.4383 = x× 1
3.7255 = x
Hence the length of QR to the nearest tenth 3.7feet

The difference between the tallest and shortest player is 15 inches.
The difference between the tallest and shortest player is 15 inches.
More than half of the players are 79 inches or taller.
The correct option is (C) and (E).
What is graph plotting?A plot is a graphical technique for representing a data set, usually as a graph showing the relationship between two or more variables.
As we see the plot.
The tallest =84 inch and the shortest =69 inch
So, The difference between the tallest and shortest player is 15 inches.
7 players are in range of 68- 78
8 players are in range of 79-84
Thus, More than half of the players are 79 inches or taller.
