Hi, What grade is this?
I am currently doing flvs too and could help you out.
Answer:
55%
Step-by-step explanation:
Out of 100 blocks 55 are shaded
so the fraction would be 55/100
55/100 = 55%
Answer:
125πkm
Step-by-step explanation:
The figure shown is a cylinder :
Volume of a cylinder is obtained using tbe relation :
V = πr²h
Where ; r = Radius ; h = height
r = 5km ; height = 5km
Hence,
V = π * 5² * 5
V = 25 * 5 * π
V = 125πkm
Answer:
8 meters
Step-by-step explanation:
Let side of square be "x"
and
Let side of equilateral triangle (triangle with all equal sides) be "y"
we know perimeter is the "sum of all the sides".
Now,
square's side is 10 longer than triangle's side, so we can write:
x = 10 + y
The perimeter of square is x + x + x + x = 4x
The perimeter of equilateral triangle is y + y + y = 3y
Now, perimeter of square is 3 times perimeter of triangle, so we can write:
4x = 3(3y)
4x = 9y
Now we replace this with 1st equation and solve for y:
4x = 9y
4(10 + y) = 9y
40 + 4y = 9y
40 = 5y
y = 40/5 = 8
The length of each side of triangle is 8 meters
