Step-by-step explanation:
9/10
=0.9
90%
=90/100
=0.9
Hence, 9/10 = 90 %

Answer:
12,200 ft²
Step-by-step explanation:
The area of the lawn = the area of the trapezium - the area of the square
Note that area of a trapezium is h*(a+b)*(1/2), where h is the perpendicular height, and a and b are the top and bottom.
Note that the area of a square is l*w, where l is length and w is width.
Therefore, the area of the lawn = [h*(a+b)*(1/2)] + [l*w]
= [80*(100+140)*(1/2)]+[50*52]
= 9600+2600
=12200
90-42=58
58/90 = 0.644444444.......
So the percent ROUNDED is 64 1/4%
Answer:
B. 7√10.
Step-by-step explanation:
√40 = √4√10 = 2√10
√90 = √9√10 = 3√10
So √40 + 2√10 + √90
= 2√10 + 2√10 + 3√10
= 7 √10.
