Answer:
540cm^3
Step-by-step explanation:
4*3*5*9=12*5*9=60*9=540
Answer:
D
Step-by-step explanation:
128pi in^3
because:
Volume = Area of the base * height
Volume= pi*r^2*height
= pi4^2 * 8
= 128pi
Answer:
the height the ladder can reach up the building to save the cat = 13.9feet
Question:
The question didn't state the height of the building. If the ladder was initially 12feet and then it was extended to another length to reach the top of the roof, we need the height of the building to enable us calculate how high the ladder can reach up the building the save the cat.
Let's consider the following question:
A cat gets stuck on the roof. If the ladder is 12 feet long and must be placed 7 feet away from the building. How high can the ladder reach up the building to save the cat if the height of the building is 12feet.
Step-by-step explanation:
The distance between the foot of the ladder to foot of the building = 7feet
adjacent = 7feet
The height of the building = 12feet
Opposite = 12feet
The length of the ladder is unknown
To find how high can the ladder reach up the building to save the cat, we would apply Pythagoras theorem
Using Pythagoras theorem
Hypotenuse ² = opposite ² + adjacent²
Hypotenuse ² = 12² + 7²
Hypotenuse ² = 144 + 49
Hypotenuse ² = 193
Hypotenuse = √193
Hypotenuse = 13.9feet
The height of the ladder to reach up the building to save the cat = 13.9feet
Answer:
Step-by-step explanation:
the average rate of change is the same as
the slope of a line m = (y2-y1)/(x2-x1)
to find if is positive of negative look at the line between the years given (for example between 1930 and 1940)
if from left to right the line goes downward the rate of change is negative
if from left to right the line goes upward the rate of change is positive
