Answer:
Area = 40 m^2
Step-by-step explanation:
The formula for any triangles is A = h x b / 2
In this problem, h = 8 m and b = 10 m
So area = 8 x 10 / 2 m^2 = 40 m^2

Step-by-step explanation:
Use the table to write a linear function that relates y to x.
Answers
Answer:
y=(3/2)x+5
Step-by-step explanation:
Sketch it out real quick on a piece of paper.
As you can tell from the table, for every 3 units along the x axis, 2 units upwards are taken along the y axis.
This makes the slope of the equation (3/2)x or (1 1/2)x
The y-intercept is at y=5 because (on the table), when x=0, y=5.
This makes the equation in point-slope form y=(3/2)x+5

A choir teacher is dividing 12 sopranos and 9 altos into singing groups. He wants each group to have the same combination of sopranos and altos, with no singers left over. What is the greatest number of groups he can make?
Answers
Answer:
3 groups
Step-by-step explanation:
Sopranos = 12
Altos = 9
Find the highest common factor of 12 and 9
12 = 1, 2, 3, 4, 6, 12
9 = 1, 3, 9
The highest common factor of 12 and 9 is 3
Therefore, the choir teacher can only have 3 groups
12 sopranos / 3 groups
= 4 sopranos per group
9 Altos / 3 groups
= 3 altos per group
Each of the 3 groups Will have 4 sopranos and 3 altos each

The quotient of the given fraction value.
Solution:
We have,

It can be written as:
[tex]\dfrac{7^{-1}}{7^{-2}}=7^{-1-(-2)}[/tex] [tex]\left[\because \dfrac{a^m}{a^n}=a^{m-n}\right][/tex]

Last week, Ann bought 9 books and 5 movies for a total of $124.
Today, Ann bought 4 books and 21 movies for a total of $318.
Assuming neither item has changed in price, what is the cost of a book in dollars?
Answers
Answer:
$6
Step-by-step explanation:
Set up a system of equations where b is the cost of a book and m is the cost of a movie:
9b + 5m = 124
4b + 21m = 318
Solve by elimination by multiplying the top equation by -21 and the bottom equation by 5:
-189b - 105m = -2604
20b + 105m = 1590
Add the equations together, then solve for b:
-169b = -1014
b = 6
So, the cost of a book is $6

9. The population of a certain animal species increases at a rate of 6.5% per year. There are currently
counted 120 of the animals in the habitat you are studying
Which function will model the expected change in the animal population from this point forward?
Answers
Answer:
FV= PV*(1 + g)^n
Step-by-step explanation:
Giving the following information:
Present Value (PV)= 120
Growth rate (g)= 6.5% per year
To calculate the future value of the population in any given year "n", we need to use the following formula:
FV= PV*(1 + g)^n
For example, in 10 years:
FV= 120*(1.065^10)
FV= 225

Answers
Answer:
A = 1739.4 cubic feet
Step-by-step explanation:
B = area of base (πr²)
h = height
A = Bh/3
A = [(18.7÷2)²π × 19] / 3
A = (9.35²π×19) / 3
A = 1739.4
