Use a^2 + b^2 = c^2
Then find the volume.
Step One
a^2 + b^2 = c^2
c = 10
b = 6
Find a
a^2 + b^2 = c^2
a^2 + 6^2 = 10^2
a^2 + 36 = 100
a^2 = 100 - 36
a^2 = 64
a = sqrt(64)
a = 8
Step Two
Find the volume
a = 8
b = 6
h = 12
V = 1/2 * a * b * h
V = 1/2 * 8 * 6 * 12
V = 288 m^3 <<<<<<< answer

Answer:
Step-by-step explanation:
We have been given that there are 170 deer on a reservation. The deer population is increasing at a rate of 30% per year.
We can see that deer population is increasing exponentially as each next year the population will be 30% more than last year.
Since we know that an exponential growth function is in form: , where a= initial value, r=growth rate in decimal form.
It is given that a=170 and r=30%.
Let us convert our given growth rate in decimal form.
Upon substituting our given values in exponential function form we will get,
Therefore, the function will give the deer population P(t) on the reservation t years from now.
Answer:
The number of letters in the one street be 220 .
Step-by-step explanation:
As given
A postman has to deliver 450 letters .
The number of letters delivered in one street is twice the number delivered in other .
Let us assume that the number of letters delivered in second street be x.
Let us assume that the number of letters delivered in first street = 2x
As given
If he is left with 120 letters .
Thus
The number of letter delivered in one and other street = 450 - 120
= 330
Than the equation becomes
x + 2x = 330
3x = 330
x = 110
The number of letters in the one street = 2 × 110
= 220
Therefore the number of letters delivered in first street be 220.
