Answer: 3.9ft²
Step-by-step explanation:
Find the area of the rectangle first:
= Length * Width
= 2 * 1.5
= 3 ft²
Find the area of the semi-circle by finding the area of a circle and dividing it by 2:
= πr²
= 3.14 * 1.5/2 * 1.5/2
= 1.76625ft²
Divide by 2:
= 1.76625/ 2
= 0.88 ft²
Add the area of the rectangle to the semi-circle:
= 3 + 0.88
= 3.9ft²
Answer:
2x+2y=310
x-y=55
multiply seond equation by 2 and adding to first equation
2x-2y=110
add
2x-2y=110
2x+2y=310 +
4x+0y=420
4x=420
divide 4
x=105
sub
x-y=55
105-y=55
minuse 105
-y=-50
mult -1
y=50
the numbers are 105 and 50
Answer:
A.
Step-by-step explanation:
Not reasonable, Why did you put that as your answer?
The whole numbers add up to more then 4 cups.
I think its the first option maybe im not sure
There are 6 things
1 2 3 4 5 6
There are 3 at a time
So 6!(things) / (6-3)! (things-how many at a time)
6!/(6-3)! Or 6!/3!
! Means multiply all below that number so
6×5×4×3×2×1/ 3×2×1
30×4×3×2×1/3×2×1
You can simplify 3×2×1 since they are both on top and bottom they cancel out
30×4= 120
