Answer:
difference in volume = 26.96h cm³
Step-by-step explanation:
The volume of a prism is the product of the base area and the height. A trapezoid prism has a trapezium as the base shape. Therefore,
volume of a trapezoid prism = area of a trapezium × height
area of the base(trapezoid) = 140 cm²
Volume = 140h
Volume of a cylinder = πr²h
where
r = radius
h = height
volume = πr²h
volume = π × 6² × h
volume = 3.14 × 36 × h
volume = 113.04h
To know how much larger the volume of the prism is than the volume of the cylinder we have to take the difference of the volume.
Recall the height are the same
difference in volume = 140h - 113.04h
difference in volume = 26.96h cm³
Answer:
x = 22
Step-by-step explanation:
rearange the equation to 25-3=x. 25-3 = 22, therefore x = 22
Answer:
8 5/6 -> 8.839 -> 177/20 -> 8.99
Step-by-step explanation:
8 5/6 = 8.333
8.839
177/20 = 8.85
8.99
Answer:
the speed of sound is 12 miles per minute
Step-by-step explanation:
To know the speed we have to divide the distance by the time because the speed of sound is constant and we have to use a formula of uniform rectilinear motion
Uniform rectilinear motion: When an object travels at a constant speed with zero acceleration it is known as uniform rectilinear motion
The distance it gives us is 1 mile and the time it gives us is 1/12 minute
v = speed
v = 1mi / (1/12 m)
v = 12 mi/m
in the result as we can see we have a whole number (12)
the speed of sound is 12 miles per minute
An expression for the difference between the two reaction times would be
√0.18 - √0.08. The result will be positive.
