When Ms. Morgan went hiking with Fuego, she saw a total of 25 tress. 6 of the trees were Elm trees. What percentage of trees were Elm trees that Ms. Morgan saw? And did she climb the trees? (remember, set up your problem like a ratio, reduce, then solve
Answer:
24%
She didn't climb any trees.
Step-by-step explanation:
There are a total of 25 trees
6 were Elm Trees
The fraction of trees that were Elm trees are 6 / 25
Converting this fraction to percentage = 6 / 25 x 100 = 24%
The question doesn't provide any information on if she climbed any trees

Answer: what is the question?
Step-by-step explanation:
The sum of three consecutive odd numbers is -27. What is the largest of the three numbers
An odd number can be written as [tex]2n+1[/tex] where n is an integer.
If [tex]2n+1[/tex] is our first odd number, the next consecutive odd number will be 2 more than that. The third one will be 4 more.
If we only add 1, we'd get an even number, so we need to add 2.
2. What are the expressions for our numbers?First number:
[tex]2n+1[/tex]
Second number (2 more than the first number):
[tex]2n+1+2=2n+3[/tex]
Third number (4 more than the first number):
[tex]2n+1+4 = 2n+5[/tex]
3. Adding our numbers togetherThe sum is these 3 numbers added together. Let's do that now:
[tex](2n+1) + (2n+3) + (2n+5)[/tex]
[tex]2n + 2n + 2n + 1 + 3 + 5\\6n + 9[/tex]
4. Solving the equationThe sum is, thus, [tex]6n+9[/tex]. We know this sum is equal to -27:
[tex]6n+9 = -27[/tex]
Subtract 9 from both sides:
[tex]6n = -36[/tex]
Divide both sides by 6:
[tex]n = -6[/tex]
5. Finding our numbersNow that we know n, we can find our 3 numbers.
For the first number, we can use its expression in section 2.
[tex]2n +1 = 2*(-6)+1 = -12+1 = -11[/tex]
For the second number, we can just use the fact that it's 2 more than our first number, -11. If you're wondering why this is, review section 1.
[tex]-11 + 2 = -9[/tex]
Same for our third number, it's 4 more than our first number or 2 more than our 2nd number:
[tex]-11 + 4 = -7\\or\\-9 + 2 = -7[/tex]
6. So the largest one is...?Our three consecutive numbers are -11, -9, and -7. As we can see, the largest of these three is -7.

Andrea is saving money for a car. She makes an hour shampooing dogs at the local groomer. After is subtracted from her paycheck she puts of her remaining check in her savings account. Let represent the number of hours Andrea works each week. Write an expression in simplest form that represents the amount of money Andrea saves each week.
Complete question :
Andrea is saving money for a car. She makes $13 an hour shampooing dogs at the local groomer. After 18% is subtracted from her paycheck she puts 50% of her remaining check in her savings account. Let x represent the number of hours Andrea works. Write an expression in simplest form that represents the amount of money Andrea saves each paycheck.
Answer:
$5.33x
Step-by-step explanation:
Given the following :
Amount earned as a local groomer = $13
Number of hours worked = x
Hence, total amount earned per paycheck = (13 * x) = 13x
Amount saved = 50% of (100% - 18%) of amount earned
= 50% of 82% of 13x
82% of 13x = (0.82 * $13x) = $10.66x
Amount saved = 50% of $10.66x
= 0.5 * $10.66x
= $5.33x
22. Linda is a salesperson for Spooner's Cleaning Service, which cleans office buildings. She
receives a 14% commission for every office that signs a contract for the cleaning service. Last week
she received $1,233.60 in commissions. What was the total value of the cleaning contracts she sold,
rounded to the nearest dollar?
Answer:
The total value of the cleaning contracts sold is $8,811
Step-by-step explanation:
Here, we are interested in calculating the value of the cleaning contracts sold.
Let the total value of the cleaning contracts sold be $x
Mathematically;
14% of x = 1233.60
14/100 * x = 1233.60
14x = 100 * 1233.60
x = 123360/14
x = 8,811.43
Which is $8,811 to the nearest dollars
Write the equation for the graph below.
HELP PLEASE
Answer:
y= 4x+1
Step-by-step explanation:
y = mx + b
The b is the y-intercept, so to find it you just need to find where the line is on the y-axis when x is zero
The slope is just rise over run (y2-y1/x2-x1), so the graph in the picture shows us that the line goes up 4 to go over 1. Therefore the slope is 4/1 which is equal to 4.
Jasper is 43 years old and his daughter Freya is 7. In n-years Jasper will be four times as old as Freya is at that point. Set up and solve an equation for n. Then state both Jasper and Freya’s ages after n-years.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Jasper's age = 43 years
Freya's age = 7
In n years, jasper will be 4 times as old as Freya
Let jasper = j
Freya = f
After n years :
j + n = 4 * f
J + n = 4 ( f + n)
43 + n = 4(4 + n)
43 + n = 16 + 4n
43 - 16 = 4n - n
27 = 3n
n = 27/3
n = 9
Jasper's age after n years :
43 + 9 = 52
Freya's age after n years :
4 + 9 = 13
5x : 9 = 8:3
Calculate the value of x.

Answer:
PQ = 14 MQ = 7 PM = 7
Step-by-step explanation:
PQ= PM + MQ = PMQ
If M is the MIDpoint it dissects PQ in half so that means PM = MQ
PQ= 5x-3+11-2x
PQ = 3x + 8
5x - 3 = 11 -2x
+2x +2x
7x - 3 = 11
+3 +3
7x = 14
7x / 7 = 14/7
x = 2
Plug in 2 for X
PQ = 3x + 8 = 3 x 2 +8 = 6 + 8 = 14
PM = 5x -3 + 5 x 2 - 3 = 10 - 3 = 7
MQ = 11 - 2x = 11 - 2 x 2 = 11 - 4 = 7

the correct measure of center is the mean.
Step-by-step explanation:
The mean of this data set is 15.44
The median is 12
The mode is 12
The A. mean measure of center is the most appropriate for this data set.
What are mean, median, and mode?The three main methods for identifying the average value of a set of integers are mean, median, and mode.
Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.
The middle value in a list that is arranged from smallest to greatest is called the median.
The value that appears the most frequently on the list is the mode.
The measure of the center is the mean value of a data set.
The mean of the data set is (20 + 6 + 42 + 13 + 15 + 10 + 9 + 12 + 12)/9.
= (139/9).
= 15.44.

Select all the angles of rotation that produce symmetry for this flower.
Answer:
Angles of rotation that produce symmetry are the angles that we can rotate the image, and the end result will be the starting image. (the angles are always measured from the x-axis)
Here we can clearly see that in each quadrant we have a petal of the flower.
Then the angles that change one quadrant into other quadrant will produce symmetry.
Those angles are:
90°, 180°, 270°, 360°, etc.
We can define the set of those angles as:
A {n*90° I n ∈ Z}

The evaluation of the expression "eleven more than a number squared, decreased by six" when t = 5 will be 30.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that the expression is, eleven more than a number squared, decreased by six;
We have to evaluate the expression when t = 5.
We have to apply the arithmetic operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷. We'll apply division by Splitting into equal halves or groups.
Suppose the variable is t,
=11 + t² - 6
If t =5
Substitute the value of t as 5 in order to evaluate the expression as,
=11 + t² - 6
=11+5²-6
=11+25-6
=30
Thus, the evaluation of the expression "eleven more than a number squared, decreased by six" when t = 5 will be 30.
