At the after school Hawk Club meeting, there were four drinks you could choose from: orange soda, Coke, Dr. Pepper, and water. There were three snacks you could choose from: peanuts, fruit, and cookies. Each student may have only one drink and one snack.
Use the counting principle to find the number of choices available
Answer: 12 possible choices
Step-by-step explanation: there are 4 drink options, and 3 snack options so using the counting principle we would do 4 x 3 to get 12. You could also check individually since it is not a big number by doing: 1 choice with coke and peanuts, another with coke and fruit, etc.

Which points are separated by a distance of 6 units? O A. (3, 2) (3,9) O B. (1,5) (1,3) O C. (2,7) (2, 1) O D. (4,1) (4,6)
Explanation:
The x coordinates are the same, so we subtract the y coordinates
7-1 = 6
This shows the points have a distance of 6 units. You can plot the two points and count the numbers of spaces between them to confirm this.

Answer:
25 mini loaves
Step-by-step explanation:
Using the first set you can divide and tell that 1 cup of flour is equal to 2.5 mini loaves, applying that to the other set you can inquire that it's true. So therefore what you need to do is multiply 2.5 times the amount of flour you are using.
10 cups = 25 mini loaves
X/5 + 3 = 2 pls help
Answer:
x=-5
Step-by-step explanation:
Group all constants on the right side of the equation
Subtract 3 from both sides:
x/5+3-3=2-3
Simplify the arithmetic:
x/5=2-3
Simplify the arithmetic:
x/5=-1
Isolate the x
Multiply to both sides by 5:
x/5 ·5= -1 · 5
Group like terms:
1/5 · 5x = -1 · 5
Simplify the fraction:
x = -1 · 5
Simplify the arithmetic:
x = -5

30 exceeds three times a number by 89 what is the number
Answer:
19.66
Step-by-step explanation:
Let x represent our unknown number
Okay so it's basically saying that 30 is greater than 3x by 89
We would represent that mathematically by:
30 - 89 = 3x
So then we just solve this like we usually would
30 - 89 = -59
-59 [tex]\div[/tex] 3 = 19.666. . .

For each year , the population of a forest of trees is represented by A(t)=115(1.025)t .In a neighboring forest, the population of the same type of tree is represented by the function B(t)=82(1.029)t .
Assuming the population growth models continue to represent the growth of the forests, which forest will have a greater number of trees after 100 years? By how many?
Answer: Forest B has 71 more trees than forest A after 100 years.
Step-by-step explanation:
I'm assuming that both functions should read as follows: (the time, t, is shown as a power, instead as a multiplication).
A(t)=115(1.025)^t
B(t)=82(1.029)^t
Although A starts out with more trees (115), B is growing at 2.9% per year [1.029], versus 2.5% [1.025]for A.
A(100)=115(1.025)^(100)
A(100) = 1359
B(100) = 82(1.029)^(100)
B(100) = 1430
Forest B has 71 more trees than forest A after 100 years.
A particular bank offer 6% interest per year compound monthly Timothy wishes to deposit $1000 write a forumla for the Amount A Timothy after n months
A formula that could be used to find the future value of Timothy's account after n months is: [tex]A = 1005^{\frac{144}{n} }[/tex]
Given the following data:
Interest rate = 6%Principal = $1000Number of times compounded = 12Time = n months to years = [tex]\frac{12}{n} \;years[/tex]To write a formula for the Amount A Timothy has after n months:
Mathematically, compound interest is given by the formula:

Where;
A is the future value.P is the principal or starting amount.r is annual interest rate.n is the number of times the interest is compounded in a year.t is the number of years for the compound interest.Substituting the given parameters into the formula, we have:
[tex]A = 1000(1 + \frac{0.06}{12} )^{12\times \frac{12}{n} }\\\\A = 1000(1 + 0.005 )^{\frac{144}{n} }\\\\A = 1000(1.005 )^{\frac{144}{n} }\\\\A = 1005^{\frac{144}{n} }[/tex]

Pregnancy can be a factor in changing body composition for women between the ages of 20 and 40, with an estimated 40 percent of women gaining excessive weight.
Body composition is affected by all the changes a body undergoes. Some may result in positive, while other in negative as side effects.
For a women between age group 20 to 40 face weight gaining problem. Generally this is becuse mostly women are pregnant during this age group and due to the biological changes occured during pregnancy may result in weight gain as a side effect to most of them.

Write an equation in Ax+By=C form for this line.
9514 1404 393
Answer:
5x -2y = 30
Step-by-step explanation:
The slope of the line ...
Ax +By = C
is -A/B. This means we can use A=5 and B=-2 in the equation we're looking for. The value of C will be one that makes the equation true at the given point.
5x -2y = 5(4) -2(-5)
5x -2y = 30
x -10 -3 4 11
y 1 6 30 120
Is the relationship linear, exponential, or neither?
Answer: Option C, neither.
Step-by-step explanation:
Here we have the table:
x: -10 -3 4 11
y: 1 6 30 120
This means that if our function is f(x), then:
f(-10) = 1
f(-3) = 6
f(4) = 30
f(11) = 120
We want to know if this represents a linear equation or an exponential equation or neither.
First, let's try with a linear equation.
We know that a linear equation can be written as:
f(x) = a*x + b
Then let's input the known values and let's see if this equation works.
We can use two of the known points to get:
f(-10) = 1 = a*-10 + b
f(4) = 30 = a*4 + b
With these equations, we can find the value of a and b, once we find these values, we can see if the equation also works for the other two points.
1 = a*-10 + b
30 = a*4 + b
First, we need to isolate one of the variables in one of the equations.
I will isolate b in the first one:
b = 1 + a*10
Now we can replace this in the other one to get:
30 = a*4 + 1 + a*10
30 = 1 + a*14
30 - 1 = a*14
29 = a*14
29/14 = a = 2.07
and using the equation b = 1 + a*10 we can find the value of b:
b = 1 + 2.07*10 = 1 + 20.7 = 21.7
Then the equation we get is:
f(x) = 2.07*x + 21.7
Now we need to see if this works for the other two points:
for x = -3, we need to get: f(-3) = 6
f(-3) = 2.07*-3 + 21.7 = 15.49
We did not get the value we expected, then we already know that the relationship is not linear.
Now let's see if the relationship can be exponential.
An exponential function is written as:
f(x) = A*(r)^x
Let's do the same as above, let's use two of the known points to find the values of A and r
f(-3) = 6 = A*(r)^(-3)
f(4) = 30 = A*(r)^4
Now we have the system of equations:
30 = A*(r)^4
6 = A*(r)^(-3)
If we take the quotient of these two equations, we get:
(30/6) = (A*(r)^4)/( A*(r)^(-3))
5 = (r^4)*r^3 = r^(4 + 3) = r^7
(5)^(1/7) = r = 1.258
And the value of A is given by:
30 = A*(1.258)^4
30/( (1.258)^4 ) = 11.98
Then the exponential equation is something like:
f(x) = 11.98*(1.258)^x
Now let's see if this equation also works for the other two points:
for x = -10, we should get f(-10) = 1
Let's see that:
f(-10) = 11.98*(1.258)^(-10) = 1.2
And for x = 11 we should get f(11) = 120
f(11) = 11.98*(1.258)^(11) = 149.6
So we get values closer to the ones we should get, but not the exact ones, so this is not an exponential relation.
Then the correct option is C, neither.
