Answer:
3/80
Step-by-step explanation:
If one fifth of apricots are split into 4 parts, each bag has 1/5 * 1/4 of the original apricots
1/5 * 1/4 = 1/20
Luke keeps 3/4 of those so that's
3/4 * 1/20 = 3/80
Answer:
c ≈ 26.4
Step-by-step explanation:
just use the pythagorean theorem
Length=2x
width=x
Perimeter of a rectangle=2(lenght)+2(width)
The first is to find out the measures of this rectangle, that is to say, you have to find the length and width of these rectangle.
We can suggest this equation:
24=2(2x)+2(x)
4x+2x=24
6x=24
x=24/6
x=4
2x=2(4)=8
The lenght will be 8 in, and the length will be 4 in.
The second; you have to calculate the area of this rectangle.
area of a rectangle= lenght x width
area=(8 in)(4 in)=32 in²
answer: the area of Marshall´s rectangular poster would be 32 in²
