Answer:
A = 105 cm²
Step-by-step explanation:
The area (A) of the trapezoid is calculated as
A =
[ (b₁ + b₂)h ]
where h is the height and b₁, b₂ the parallel bases
Here h = 5 , b₁ = 24 and b₂ = 18 , then
A =
[ (24 + 18)5 ]
=
(42 × 5)
=
× 210
= 105 cm²
volume for a sphere (ball) is 4/3 x PI x r^3
r = 6.3, r^3 = 6.3^3 = 250.047
volume = 4/3 x 3.14 x 250.047 = 1046.863
rounded to nearest hundredth = 1046.86 cubic inches
Answer:
x=-9,y=-4
Step-by-step explanation:
2x-3y=-6...(1)
-2x-2y=26...(2)
To solve we will have to eliminate one of the given variables, the variable to be eliminated is x
And it can be done by adding up (1) and (2)
It gives
-5y=20
Divide both sides by-5
y=-4
Then substitute the value of y into (1)
2x-3(-4)=-6
2x+12=-6
Substrate 12 from both sides
2x=-18
Divide both sides by 2
x=-9
Therefore x gives -9 and y gives-4
Answer:
0.185185185185185185.........
Step-by-step explanation:
i used a calculator, to the nearst tenth is 0.18 to the nearest 100th is 0.185 also the 185 is repeating so u put a line over the numbers 185
