Answer:
1. 8.3%
Step-by-step explanation:
Relative error = absolute error/expected measurement
The expected measurement is given as 6 ft.
Now, the absolute error is usually equal to half of a unit of the measure.
This means the absolute error in this case is ½ × 1 = 0.5 ft
Thus, the exact measurement will be;
6 ± 0.5
Thus;
Relative error = 0.5/6
Relative error = 0.083
Expressing it in percentage gives 8.3%
Minus 4x from both sides
x+3=0
minus 3 from both sides
x=-3
Not 100% sure its been a while. but ill try to explain.
so for the box on the top the sides are 10 and 8. the squares area is 80.
or the triangles, the height is 3 inches and base is 8 inches. so 8x3 is 24. but for triangles you divide by two. so it would be 12 for one triangle resulting in 24 for both of them.
now lets combine the bottom two boxes. each side is 10 because 10 on one side and 5+5 is 10. so 10x10=100.
if we take all the values and add them up well get 204.(80+24+100=204.
have a good day
4(2 + 3) - [7 - [4 - (8 + 5)]]
First, do the parentheses:
4(5) - [7 - [4 - 12]]
Then complete the rest from the inside out:
20 - [7 - (-8)]
20 - 15 = 5
I thinks its y=8

Not 100% for sure
