Answer: 2.5 ft
Step-by-step explanation:
The volume of a rectangular prism is given by the following formula:
(1)
Where:
is the length of the base
is the width of the base
is the height of the prism
On the other hand, tha area of a rectangle is:
(2)
Then, we can rewrite (1) in terms of (2):
(3)
Now, we know the value of the volume and the area of the base:
Substituting these values in (3):
(4)
Isolating :
This is the height of the truck
Answer:
The population density is 618.93 per square mile.
Step-by-step explanation:
It is given that,
No. of people, N = 70,000
The radius of a city's town hall, r = 6 miles
We need to find the population density. It can be calculated by the formula i.e. number of people divided by area of land such that,
So, the population density is 618.93 per square mile.
Divide 252 by 21.
21 times 12 = 252
12 is 9 units shorter than 21.
so the answer is 12 inches by 21 inches
you work backwards from the area
area = width times length
a = wl
we know w is 9 units shorter than the length
so now we have the equation 252=(l-9) times l
plug in 21 for l and then solve there is your answer.
Answer:
3/1
Step-by-step explanation:
The average rate of change is the distance between y values divided by the distance between x values. We know this as rise/run or slope for linear equations. For non-linear equations, we calculate the average over an interval.
This function has y-values of -1 at x=0 and 5 at x=2.
We add -1+5=6 and divide this by 2-0=2.
6/2=3.
The y-values on average change 3 units for every 1 unit of the x-values.
53 times 70%
53 times 0.7 is 37.1
