A+0=0+a=0 is true except for all teal numbers except 0 true or false

jolli1 [7]

Try it with some random number, like a=3.

Is "3+0 = 0+3 = 0" true? No.

If you were doing multiplication, then it would be true, but not with addition.

One side of trapezoid is 10 inches. The side parrellel to this is twice as long as this side. The height is half as long as the

madam [21]

The first side is 10 inches
the side parallel to this is (10×2)= 20 inches
Height is half the length=1/2×20=10 inches
The area of trapezium is given by:
Area=1/2×h×(a+b)
where a and b are the sides, h is the height. Thus the area will be:
Area=1/2×10×(20+10)
=1/2×10×30
=150 sq. inches

Solve for y x+2y=6. what's the answer

Luda [366]

Solve for y

x+2y=6

Add (-x) to both sides:

x + 2y + (-x) = 6 + (-x)

Simplify:

2y = 6 - x

Divide both sides by 2

2y/2 = (6-x) / 2

2y/2 = 6/2 - x/2

y = 3 - x/2

Rounded to the nearest hundred cubic meters, what is the total capacity (cone and cylinder) of the storage container?

hichkok12 [17]

The picture in the attached figure

we know that
the total capacity of the storage container=volume of a cone+volume of cylinder

step 1
find the volume of a cone
volume of a cone=(1/3)*pi*r²*h
r=6 m
h=8 m
so
volume=(1/3)*pi*6²*8-----> 301.44 m³

step 2
find the volume of the cylinder
volume of a cylinder=pi*r²*h
r=6 m
h=10 m
s6
volume=pi*6²*10----> 1130.40 m³

total volume=301.44+1130.4-----> 1431.84 m³-------> 1400 m³

the answer is
1400 m³
