PLEASE HELP
Answers
The best approach to solve this question is to build a table and start entering the given information in it. When the given data has been entered fill the rest on basis of the data you have.
18 students from grade 10 participate in at least one Extracurricular activities. This means the rest students i.e. 22 students from grade 10 do not participate in Extracurricular activities.
32 students from grade 9 participate in at least one Extracurricular activities. This means total students who participate in at least one Extracurricular activities are 18 + 32 = 50 students.
The rest 50 students do not participate in at least one Extracurricular activities. From these 22 are from class 10. So the rest i.e. 28 are from class 9.
Based on this data we can fill the table as shown in image below.

dont sue me if i get something wrong, im human @ other users
Answer:
Emma made a profit of $298.00
Step-by-step explanation:
Emma bought two tires = $35.00 each
Cost of two tires = 35 × 2 = $70.00
She bought three rims = $75.00 each
Cost of three rims = 75 × 3 = $225.00
She bought five headlight covers = $4.00 each
Cost of 5 headlight covers = 5 × 4 = $20.00
Total Cost price of the items = 70 + 225 + 20 = $315.00
She sold both tires = $65.00 each
= 65 × 2 = $130.00
She sold three rims = $136.00 each
= 136.00 × 3 = $408.00
She sold 5 headlight covers = $15.00 each
= 15 × 5 = $75.00
Selling price of all the items = 130 + 408 + 75 = $613.00
Profit = selling price - cost price
P = 613.00 - 315.00 = $298.00
Emma made a profit of $298.00

find the slope pf the line on the grap (-2,2),(4,0) reduce all fractional answers to the lowest term.
1). -3
2 ). -1/3
3). -1
Answers
We're trying to find the slope of the line on the graph (not given, but that's okay). We're given the points (-2, 2) and (4, 0).
Using the slope equation, we simply just have to plug our points in and boom - there's your slope!
Slope equation : m = y₂ - y₁ / x₂ - x₁
Now, using our given points, we can very simply plug everything in! :)
Now, in case you didn't know which number aligns with which variable, I'll go ahead and help you out with this.
x₁ = -2 , x₂ = 4 , y₁ = 2 , y₂ = 0
Now, let's plug and chug!
m = (0 - 2) / (4 - (-2))
Simplify.
m = -2 / 4 + 2
Simplify.
m = -2 / 6
Simplify.
m = -1/3
So, our slope is -1/3.

To find out how many people have not yet decided who they plan to vote for, let's first calculate the total number of people asked.
[tex]Total[/tex] [tex]people[/tex] [tex]asked[/tex] [tex]= 1,500[/tex]
Now, let's find out how many people have already decided:
[tex]For candidate X: 45% of 1,500\\\\= 0.45 * 1,500 = 675 people\\For candidate Y: 38% of 1,500\\= 0.38 * 1,500 = 570 people[/tex]
Now, let's subtract the people who have already decided from the total number of people asked:
[tex]Total people who have not decided = Total people asked - (People for candidate X + People for candidate Y)[/tex]
[tex]= 1,500 - (675 + 570)\\= 1,500 - 1,245\\= 255[/tex]

if Trigg spends 23.50 on gas, what is the total distance the boys could travel
Answers
To determine the total distance Trigg could travel with $23.50, you divide this amount by the cost per gallon of gas and then multiply by the car's MPG. Using an MPG of 27 and a gas price of $2.86 per gallon as example figures, Trigg could travel approximately 221.859 miles.
To calculate the total distance Trigg could travel with $23.50 spent on gas, we need to know the car's fuel efficiency (miles per gallon) and the current gas price per gallon. Since this information isn't provided directly in your question, let's use the example information provided. Assuming a car gets 27 miles per gallon and gas costs $2.86 per gallon, we first calculate how many gallons Trigg can buy with $23.50:
Divide $23.50 by the cost of a gallon of gas ($2.86) to find out how many gallons he can purchase:$23.50 / $2.86 = 8.217 gallons (approximately).Multiply the number of gallons by the fuel efficiency of the car to find out the total distance: 8.217 gallons x 27 miles per gallon = 221.859 miles (approximately).
Therefore, with $23.50 and the given fuel efficiency and gas price, Trigg could travel approximately 221.859 miles.
helen didvided her colored pencils evenly among herself and three freinds. write an expression to represent the number of pencils each person received
Answers
This would then signify that the expression would look like the following:
[tex]\boxed{p\div(4)}[/tex]
We really do not know how many pencils Helen had, so this is why p is in the equation.
The mathematical expression to represent the number of colored pencils each person received is [tex]\frac{P}{4}[/tex], where P represents the total number of pencils.
The question asks us to write an expression to represent the number of colored pencils each person received when Helen divided her pencils evenly among herself and three friends. To do so, we should first denote the total number of colored pencils Helen has as P. Since there are four people in total (Helen and her three friends), we need to divide the total number of pencils by four.
The expression to represent the number of colored pencils each person received is thus [tex]\frac{P}{4}[/tex]. This formula can be used to calculate how many pencils each person would get if you replace P with the actual number of pencils.

Jenny live 6 1/4 miles from school. Raymond lives 5 1/2 miles from school. How much farther from school does Jenny live then Raymond? Write an equation and solve it
Answers
6 1/4 - 5 2/4= 3/4
The answer is 3/4.
To find out how much farther Jenny lives from school than Raymond, we subtract Raymond's distance from Jenny's, converting both to improper fractions to subtract easily, resulting in Jenny living 3/4 of a mile farther than Raymond.
Explanation:The question asks how much farther from school Jenny lives compared to Raymond. Jenny lives 6 1/4 miles from school, and Raymond lives 5 1/2 miles from school. To find out how much farther Jenny lives from the school than Raymond, we can write an equation and solve it.
Let ‘d’ represent the difference in distance between how far Jenny lives from the school and how far Raymond lives from the school. The equation can be written as:
d = 6 1/4 miles - 5 1/2 miles
To solve this, we first convert the mixed numbers to improper fractions. Therefore, 6 1/4 miles becomes 25/4 miles, and 5 1/2 miles becomes 11/2 miles. Our equation now looks like this:
d = 25/4 miles - 11/2 miles
We need a common denominator to subtract these fractions, which is 4 in this case. So we convert 11/2 miles into 22/4 miles. The revised equation is:
d = 25/4 miles - 22/4 miles
When we subtract 22/4 from 25/4, we find d = 3/4 miles. Therefore, Jenny lives 3/4 of a mile farther from school than Raymond.

now, if you notice there, for a cylinder with radius "r" and height "h", that is its volume.
and for a cone that has the same "h" and "r' as the cylinder's, that is its volume, however, notice, the cone's volume is one third of that of the cylinder's.
so if the cylinder has a volume of 24, well, you already know what is the cone's.

During dance practice, Sasha drank 21⁄2 pints of water, and on the way home she drank 1⁄2 cup of water. How much water did she drink in total?
Cups and ounces
Answers
Sasha drank a total of 5.5 cups of water, considering that 1 pint equals 2 cups.
Explanation:The question is asking us to determine the total amount of water Sasha drank in pints and cups. First, it is important to note that 1 pint equals 2 cups. Sasha drank 21⁄2 pints of water during dance practice, which is equivalent to 5 cups of water (2.5 pints * 2). On the way home, she drank an additional 1⁄2 cup of water. Therefore, in total, Sasha drank 5.5 cups of water.

Tom can whitewash a fence at a rate of six square feet per minute. Huck can whitewash a fence at a rate of ten square feet per minute. Tom starts painting her fence, and five minutes later, Huck starts to help Tom. When they finish painting the fence, each person has painted half of the fence. How many square feet is the fence?
Answers
T = Tom = 6 square feet a minute.
The "distances" they have to go are equal since both do the same amount.
R_Tom * time_tom = R_Huck * time huck
6* (t) = 10 * (t - 5)
6t = 10t - 50 Add 50 to both sides
6t + 50 = 10t Subtract 6t from both sides.
50 = 4t Divide by 4
50/4 = t
12.5 = t
This means that tom was working for 12.5 minutes. He does 6 square feet a minute The amount of fence he does is 12.5 * 6 = 75 square feet.
Since Huck does the same amount the total is 75 * 2 = 150 square feet total.
