In a package of 40 skittles, 35% were red. How many were not red?
My teacher said she got 26 but I'm puzzled and don't know how to get that.
First you would take 35% of 40:
.35 * 40 = 14
That's how many skittles ARE RED. Now, subtract 14 from 40:
40 - 14 = 26
Hope this helps!

A dog walker charges a flat rate of $6 per walk plus an hourly rate of $30. How much does the dog walker charge for a 45 minute walk? Write an equation in function notation for the situation and then use it to solve the problem. Determine if the given statement is true or flase.
The dependent variable is the number of hours true or false
The function for the walker fee is f(h)= 30h+6 true or false
The dog walker charges $22.5 for a 45min walk true or flase
Step 1
Find the equation in function notation
Let
h-------> the number of hours
y-------> the function for the walker fee in dollars
we know that
the hourly rate is [tex]30\frac{\$}{hour}[/tex]
[tex]y=6+30h[/tex]
in this linear equation
the independent variable is the variable h
the dependent variable is the variable y
Convert to function notation
Let
[tex]f(h)=y[/tex]
[tex]f(h)=6+30h[/tex]
Step 2
Find how much does the dog walker charge for a 45 minute walk
Convert the time in hours
[tex]1\ hour=60\ minutes[/tex]
[tex]45\ minutes=45/60=0.75\ hours[/tex]
substitute in the equation
For [tex]h=0.75\ hours[/tex]
[tex]f(0.75)=6+30*(0.75)=\$28.5[/tex]
therefore
the answer is
the dog walker charge for a 45 minute walk [tex]\$28.5[/tex]
Statements
Step 3
The dependent variable is the number of hours true or false
The statement is false,
because the independent variable is the number of hours and the dependent variable is the walker fee in dollars
Step 4
The function for the walker fee is f(h)= 30h+6 true or false
The statement is True --------> see the Step 1
Step 5
The dog walker charges $22.5 for a 45 min walk true or false
The statement is False
Because the dog walker charges for a 45 minute walk [tex]\$28.5[/tex]
The dependent variable is indeed the number of hours. The proper function for the walker's fee is f(h)= 6+30h. When using the function to calculate a 45-minute walk, we find the cost to be $28.5, not $22.5.
Explanation:
The subject of this question is Mathematical analysis, more specifically, function notation and applied arithmetic. Here, the dependent variable is indeed the number of hours, it is true. We can express the cost of dog walking as a function of the time in hours. We denote the function with 'f' and the hours with 'h'. The flat rate plus the hourly rate can be express as f(h) = 6 + 30h. So the function given f(h)= 30h+6 is true.
To find a 45-minute walk cost, we need to express 45 minutes in hours, because our function is defined in terms of hours. 45 minutes is 0.75 of an hour. Substituting h = 0.75 into the function, we get f(0.75) = 6 + 30* 0.75 = 6 + 22.5 = 28.5, not $22.5. So, the statement 'The dog walker charges $22.5 for a 45min walk' is false.

to manage a rental property a property manager charges $59 per month plus 8%of rent
A property manager charges = $59.
Rent is = 8% of rent.
Let us assume rent is = $ r per month.
Therefore, 8% of r would be 0.08 r.
Now, the total monthly fees charged by the property manager = Fix charge + 8% of rent.
Let us take total montly charge by T.
Therefore, we can setup an equation:
T = 59 + 0.08r.
Therefore, T = 59 + 0.08r is the equation to represent the total monthly fees charged by the property manager.
The total monthly fees formula is F = 59 + 0.08R. If Jack pays $165 per month, the rent is $1,325. With a rent increase to $1,495, the fees increase by $13.60 per month.
a) Equation for Total Monthly Fees
The total monthly fees charged by the property manager can be represented by the equation:
F = 59 + 0.08R
where F is the total monthly fee and R is the monthly rent.
b) Calculating Monthly Rent
If Jack pays the property manager $165 each month, we can set up the equation from part (a) and solve for R:
165 = 59 + 0.08R
First, subtract 59 from both sides:
106 = 0.08R
Next, divide by 0.08
R = 1325
Therefore, the monthly rent on Jack's property is $1,325.
c) Increased Fee with Higher Rent
If Jack raises the rent to $1,495, we need to find the new monthly fee and calculate the increase:
Total fee at $1,495 rent:
F = 59 + 0.08 × 1495
F = 59 + 119.6
F = 178.6
Previously, Jack was paying $165, so the increase in fee is:
178.6 - 165 = 13.6
Jack will pay $13.60 more each month to the property manager.
Complete Question:- To manage a rental property, a property manager charges $59 per month plus 8% of the rent.
a) write an equation to represent the total monthly fees charged by the property manager.
b) if jack pays the property manager $165 each month, what is the monthly rent on his property?
c) if jack raises the rent on the house to $1,495, how much more will he pay the property manager each month?

Mark studied a group of 30 whales. If each whale weighed approximately 3.8 * 10^5 pounds, find the total weight of all 30 whales. Express your answer in scientific notation.
Answer: The total weight is [tex](1.14)(10^{7})[/tex] pounds.
Step-by-step explanation:
1. To solve this problem you need to multiply the number of whales by the weight. Based on the given information, the weight of each whale is approximately [tex](3.8)(10^{5})[/tex] pounds, therefore:
[tex](30)[(3.8)(10^{5})]=11,400,000[/tex] pounds.
3. To express the result in scientific notation, you must move the decimal point to the right until you have a non-zero number on the left of the decimal point. Then, it is:
[tex](1.14)(10^{7})[/tex]
Answer: The group weights 1.14x10^7 pounds
Step-by-step explanation:
The group has 30 whales.
Each whale weights 3.8x10^5 pounds, then, 30 whales weight 30 times that amount:
Total weight = (30)*(3.8x10^5)
Remember that for the scientific notation we want only one digit before the decimal point.
Here, i will use that 30 = 3x10^1
(3x10^1)*(3.8x10^5) pounds = (3*3.8)x10^(5 + 1) pounds
(11.4)x10^6 pounds
and 11.4 = 1.14x10^1
(11.4)x10^6 pounds = 1.14x10^(1 + 6) pounds = 1.14x10^7 pounds
the average of m, n, and -1 is 0. What is the value of m+n?
Final answer:
Given that the average of m, n, and -1 is 0, the sum of m+n is calculated to be 1.
Explanation:
The question asks for the sum m+n given that the average of m, n, and -1 is 0. To find the sum, we can set up an equation using the definition of the average:
(m + n + (-1)) / 3 = 0
Solving this equation, we get:
m + n - 1 = 0
And once we add 1 to both sides:
m + n = 1
Therefore, the value of m+n is 1.

The mean of a set of six numbers is 4.5. If the mean of two of the numbers is 5.5, find the mean of the remaining four numbers
The mean of the remaining four numbers is 4.
To find the mean of the remaining four numbers, we need to first find the sum of all six numbers.
The mean of six numbers is given as 4.5. So, the sum of all six numbers is [tex]\(4.5 \times 6 = 27\)[/tex].
Now, we know that the mean of two of the numbers is 5.5. So, the sum of these two numbers is [tex]\(5.5 \times 2 = 11\)[/tex].
To find the sum of the remaining four numbers, we subtract the sum of the two numbers with a mean of 5.5 from the sum of all six numbers:
27 - 11 = 16
Now, since the mean is the sum of all numbers divided by the count of numbers, the mean of the remaining four numbers is [tex]\( \frac{16}{4} = 4 \)[/tex].
Therefore, the mean of the remaining four numbers is 4.

7. Loan amount = $12000
Monthly payment = $380
Duration of the repayment = 3 years = 3(12) = 36 months.
Total amount Jason repaid = 36 × 380 = 13680
Interest on loan amount = amount repaid - loan amount
= 13680 - 12000
= 1680
Hence, total amount Jason paid in interest on loan = $1680 and the correct option is (D).
8. Loan amount = $35000
Monthly payment = $315
Duration of the repayment = 10 years = 10(12) = 120 months.
Total amount Gerald repaid = 120 × 315 = 37800
Interest on loan amount = amount repaid - loan amount
= 37800 - 35000
= 2800
Hence, total amount Gerald paid in interest on loan = $2800 and the correct option is (B).

Given: △ABC, m∠A=60° m∠C=45°, AB=8 Find: Perimeter of △ABC, Area of △ABC
To find the perimeter of the triangle, add the lengths of all three sides. Use the Law of Sines to calculate the lengths of the other two sides. To find the area, use the formula: Area = (1/2) * AB * AC * sin(C)
Explanation:To find the perimeter of the triangle ABC, we need to add the lengths of all three sides. Given that AB = 8, we can calculate the length of the other two sides using the Law of Sines. Since m∠A = 60° and m∠C = 45°, we have:
AC/sin(60°) = AB/sin(m∠C)
AC/sin(60°) = 8/sin(45°)
Solving for AC, we find that AC is approximately 9.66. Similarly, we can find BC using:
BC/sin(∠C) = AB/sin(∠A)
BC/sin(45°) = 8/sin(60°)
Solving for BC, we find that BC is approximately 8.62. Therefore, the perimeter of triangle ABC is:
8 + 9.66 + 8.62 = 26.28
To find the area of the triangle, we can use the formula:
Area = (1/2) * AB * AC * sin(∠C)
Area = (1/2) * 8 * 9.66 * sin(45°)
Calculating this, we find that the area of triangle ABC is approximately 30.36 square units.
