Answer: -20
Step-by-step explanation: Using the same expression except positive numbers, 4 x 5 = 20.
In this case, we can use this equation to find the product for the expression
4 x -5.
If 4 x 5 = 20, then 4 times -5 will also equal 20. However, since there is a negative factor in this expression, our answer will be negative causing our answer to be <u>-20.</u>
Answer:
The height of the water is
Step-by-step explanation:
step 1
Find the volume of the tank
The volume of the inverted right circular cone is equal to
we have
substitute
step 2
Find the 25% of the tank’s capacity
step 3
Find the height, of the water in the tank
Let
h ----> the height of the water
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional
substitute
where
r is the radius of the smaller cone of the figure
h is the height of the smaller cone of the figure
R is the radius of the circular base of tank
H is the height of the tank
we have
-----> volume of the smaller cone
substitute
Simplify
Answer: -5x+6
Step-by-step explanation:
Find slope through slope formula (y₂-y₁)/(x₂-x₁)
- By doing this you find that the slope is -5
Then the y-intercept is found through the intersection of the y-axis.
