Find the geometric mean between 28 and 32. Round to the nearest tenth if necessary.
Answers
Answer: The geometric mean is √24 * 32 = √768 = 16√3.
The geometric mean between 28 and 32 is 28.29 after using the formula of the geometric mean.
What is mean?
It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
Let x be the geometric mean between 28 and 32
The formula for the geometric mean:
x = √(a×b)
x = √(28×32)
x = √800
x = 20√2
x = 28.284
or
x = 28.29
Thus, the geometric mean between 28 and 32 is 28.29 after using the formula of the geometric mean.

Depending on traffic, Danielle’s drive to the park is p minutes from work and 90 minutes from the park to her home. If Danielle’s total commute (c) took two hours today, how long was Danielle’s drive to the park from work? Set up your equation when total commute time (c) depends on the time to drive to the park (p).
Equation: ______________
p=88 minutes
p=70 minutes
p=40 minutes
p=30 minutes
Answers
Answer:
The equation is;
p + 90 = 120 minutes
Danielle’s drive from work to the park took 30 minutes ( p = 30 minutes)
Step-by-step explanation:
Here, we want to write and solve an equation
Here, we want to get the time taken by Daniele from the park to work
From the question, the total commute is two hours
since 1 hour is 60 minutes, it follows that 2 hours is 120 minutes
Now, if we added the time taken to commute both journeys, we have the total as 2 hours
This means;
p + 90 = 120 minutes
p = 120 - 90
p = 30 minutes

You sell small and large candles at a craft fair. Small candles cost $4 each and large candles cost $6 each. You collect $144 after selling a total of 28 candles. How many of each type of candle did you sell? Write a linear system to represent the situation. Be sure to define your variables.
Answers
Answer: Small Candle = 12, Large Candle = 16
Step-by-step explanation:
Equation is this, s+l=28 2nd equation is 4s+6l=144
now you multiply every number in the second equation by -6 since positive 6 is the second equations second constant. Now you got -6s-6l=-168 And 4s+6l=144. The -6l and positive cancel so now you got -6s + 4s = -168+144. Now you got -2s = -24. Divide them both by negative two then you get s = 12. 28 candles total - 12 = 16 so 16 large candles and 12 small. L = large candles, S = small candles.
Answer:
8 small candles
16 large candles
Step-by-step explanation:
1. Approach
Set up a system of equations to solve this problem. Call the number of small candles sold (x), and the number of large candles sold (y). Have one expression model the amount of money earned, the other model the number of candles sold. Then, solve this system of equations using the process of elimination. In the process of elimination, one multiplies one of the equations by a term such that one of the coefficients of a variable in one of the equations is the additive inverse of the corresponding variable in the other equation. This means that when one adds the two equations, one of the variables will eliminate. Then one can solve for the other variable, and finally, substitute the value of the variable that one found back into one of the equations, and solve for the value of the other variable.
2. Set up a system of equations
Use the given information to set up a system of equations to describe the amount earned, and the amount sold
x + y = 28 -> amount sold
4x + 6y = 144 -> amount earned
3. Solve the system
As explained above, the process of elimination is a method of solving a system of equations. In the process of elimination, one multiplies one of the equations by a term such that one of the coefficients of a variable in one of the equations is the additive inverse of the corresponding variable in the other equation. This means that when one adds the two equations, one of the variables will eliminate.
x + y = 28 (*-4)
4x + 6y = 144
-4x - 4y = -112
4x + 6y = 144
___________
2y = 32
/2 /2
y = 16
4. Solve to find out how much of the other candle was sold
Now back solve, substitute the found value into one of the equations, and solve to find the other value
x + y = 28
y = 16
x + 16 = 28
-16 -16
x = 8
