Answer:
8m
Step-by-step explanation:
The area of a square is length*width.
We can square root the area to get the length of each side. Since the shape is a <em>square</em>, the lengths are the same.
=8
One side is <u>8m</u>.
I don’t know what answers you have but I think it’s 23.4
Answer:
36 objects
Step-by-step explanation:
You want the value of x when t=9, so you're solving ...
9 = 0.007x^2 +0.003x
9 = 0.007(x^2 + 3/7x)
From here, we observe that an approximation is probably sufficient.
9/0.007 = x(x +3/7) . . . . . the expression on the right is nearly x^2
x ≈ 3/√.007 ≈ 35.9 ≈ 36
We can check:
.007(36)(36 3/7) = 9.18
.007(35)(35 3/7) = 8.68
To keep the computer busy for 9 seconds, it needs to sort 36 objects.
Answer:
624
Step-by-step explanation:
the area of the triangles:
12*10 = 120
120/2 = 60
since there are 2 triangles of the same dimensions that make up the surface area 60 + 60 = 120
area of the rectangles:
13*14 = 182
since there are 2 rectangles of the same dimensions 182 + 182 = 364
The last rectangular:
10*14 = 140
add all areas:
120 + 364 + 140 = 624
