all sides of a square are equal and there are 4 sides so divide 20 by 4 and you get 5 ft
5/8 is 0.625 , so that would be the decimal for it
Answer:
The answer would be 80 ° because 5×( 2 + 13 or x +1 ) is 80
Step-by-step explanation:
ABD is 80°
If DEB is 42 °
∠ ABD = 5(2X+1)
∠ DBC = 3X+6
∠ EBC = Y +135/2
∠ ABD and ∠ DBC are linear pairs
∴ ∠ ABD +∠ DBC = 180
∴ 5(2X+1) + 3X+6 =180
solve for x
∴ x = 13
∴∠ ABD = 5(2X+1) = 5(2*13+1) = 135
∠ DBC = 3x+6 = 3*13+6 = 45
∠ ABD and ∠ EBC are vertical angles
∴ ∠ ABD = ∠ EBC = 135
∴ y +135/2 = 135
∴ y = 135/2
Answer:
Mr. Kelner is going to save $60
Step-by-step explanation:
Remark
The easy way to do this is to change 5/8 to a decimal and worr y about changing it back to a fraction if you need to.
15 5/8 = 15.625 The easy way to find 5/8 is to use your calculator. 5 ÷ 8 = on most calculators.
You want 12 of these
1 leg is 15.625 inches long.
12 legs = x
1/12 = 15.625 / x Cross multiply
x = 12 * 15.625
x = 187.5 inches
Just how many feet is that? Divide by 12 to get the number of feet 187.5 / 12 =
15.625 feet.
Usually 2 by 4s are 8 or 12 feet long. For 8 feet you will need 2 of them and for 12 feet unfortunately you will need two as well.
