9. As part of a class project, Areeb collected $126 in donations for a local
hospice. That amount was 7% of the total amount collected by the class.
How much money did the class collect in all?
Answer:
So you're given that 7% is $126, and you have to find 100%. In order to do this you could set up proportions.
1) 126/7=x/100
Next you can cross multiply and you'll get:
2) 12600=7x
Now divide each side by 7
3)12600/7=7x/7
And simplify
4)1800=x
Solution: $1800

In a survey on favorite parts of college, students were asked to choose their favorite professor (from a list of four popular professors), favorite meal in the dining hall (from a list of five popular meals), and favorite weekend activity (from a list of six popular activities). Calculate the number of different ways the survey can be filled out if students select one from each category.
Answer:
The survey can be filled out in 120 different ways.
Step-by-step explanation:
The possible options are:
One professor from a set of four.
One meal from a set of five.
One weekend activity from a set of six.
Calculate the number of different ways the survey can be filled out if students select one from each category.
The multiplication of the number of possible outcomes for each trial. So
4*5*6 = 20*6 = 120
The survey can be filled out in 120 different ways.
Express the ratio below in its simplest form.
2.5: 3.5
Answer:
Ratio = 5:7
Step-by-step explanation:
2.5 :3.5
To simplify a ratio, we must find a common factor that easily divides them.
Both of them have a common factor of 0.5, so we divide each of them by 5
2.5/0.5 = 5
3.5/0.5 = 7
So, the final ratio we end up with is equal to 5:7.

How many hours will it take to hike 15 miles
Answer:
1 hour and 15 minutes.
Step-by-step explanation:
Average Hiking Speed is generally between 1 MPH to 3 MPH depending on how much hill (vertical gain) is involved, amoung other factors. Based on the plan you entered above TrailsNH estimates your average hiking speed to be closer to 1.5 MPH, or 3h 23m of moving time for a 5 mile hike up 2000 vertical feet of elevation gain. Compare that with Naismith's Rule which says your average hiking moving time is around 2h 36m.
I calculate Your Estimated Hiking Time by taking Naismith's Rule and applying an adjustment to match your plan. The adjustment (currently calculated as +30%) uses a sliding scale to add or subtract the effort involved. Your plan is currently set as: pace = Normal, treadway = Rough, and pack weight = Regular.
Naismith's Rule estimates hiking time on reasonably easy ground based on 19½ minutes for every mile, plus 30 minutes for every 1,000 feet of ascent. For example: A 2 mile hike over a 500 foot hill, Naismith's Rule estimates will take 52 minutes. That is a pace of 26 minutes per mile, or an Average Hiking Speed of 2.3 miles per hour.
Book Time estimates hiking time in the mountains based on 30 minutes for every mile, plus 30 minutes for every 1,000 feet of ascent. This is the estimate commonly used in guide books. For example: A 2 mile hike over a 500 foot hill, Book Time estimates will take 1 hour and 15 minutes. That is a pace of 37 minutes per mile, or an Average Hiking Speed of 1.6 miles per hour.

In triangle LMN, m∠L = (4c + 53)°. If the exterior angle to ∠L measures 87°, determine the value of c.
c = 87
c = 8.5
c = 35
c = 10
Therefore , the solution of the given problem of trigonometry comes out to be c =6.
Explain trigonometry.Trigonometry is a discipline of mathematics that examines relationships between triangles' angles and sides. Trigonometry is used frequently in geometry because every straight-sided form may be broken down into a group of triangles. Trigonometry and other areas of mathematics, particularly calculus, real or complex, infinite series, logarithms, and infinite series, have a staggering amount of interrelationships.
Here,
Given :
In triangle LMN,
m∠L = (4c + 53)°.
∠L = 87°
To find the value of c:
87° = (4c + 53)°
=> 4c = 87-53
=> 4c = 24
=> c =6
Therefore , the solution of the given problem of trigonometry comes out to be c =6.

How did the United States' entry into World War I change the culture and
international political policies of the country?
The United States' entry into World War I led to a rise in nationalism and patriotism, as well as a shift towards a more interventionist foreign policy. This had a lasting impact on the culture and international political policies of the country.
Explanation:The United States' entry into World War I marked a significant shift in the culture of the country. Prior to the war, the United States had maintained a policy of isolationism, with a focus on avoiding involvement in foreign conflicts. However, the country's entry into the war marked a shift towards a more interventionist foreign policy, as the United States began to take a more active role in international affairs.

An advertising company is designing a new logo that consists of a shaded triangle inside a parallelogram. What is the area, in square units, of parallelogram ABCD? Enter your answer in the box.
In the new logo, what fraction of the parallelogram is shaded.
a. The area of the parallelogram ABCD in this problem is given as follows: 24 units squared.
b. The fraction of the area of the parallelogram that is shaded is given as follows: 1/4. (option C).
How to obtain the area of a parallelogram?The area of a parallelogram is given by the multiplication of the length of the base by the height, as follows:
Area = base x height.
The base and the height for this problem are obtained counting the number of dots, hence:
Base: 4 units.Height: 6 units.Hence the area is given as follows:
Area = 4 x 6
Area = 24 units squared.
The shaded region is composed by a triangle with base 4 and height 3, hence:
Area shaded = 0.5 x 4 x 3 = 6 units squared.
(formula for the area of the triangle).
Meaning that the fraction is given as follows:
6/24 = 1/4.

Write three to five sentences explaining which levels of production provide Alonzo’s Cycling with the maximum profit
The data provided in the table implies that Alonzo's Cycling should produce five or six bikes if it wants to maximize its profits.
What is profit maximization?Profit maximization is a process that businesses go through to make sure the best levels of output and prices are realized in order to maximize their returns. The company modifies important variables like sale price, production costs, and output levels in order to achieve its profit objectives.
This is because the sixth bike is the point at which the marginal revenue matches the marginal cost. The company will make $90 in profit with the sale of its fifth or sixth bike each day. After that, the profit begins to fall with each sale.

The price of an item has risen to $387 today. Yesterday it was $180. Find the percentage increase
Answer:
115%
Step-by-step explanation:
Given that,
The initial price of an item = $180
The final price of an item = $387
We need to find the percentage increase. It can be calculated as follows :
[tex]\%=\dfrac{\text{Change in price}}{\text{initial price}}\times 100[/tex]
Put all the values,
[tex]\%=\dfrac{387-180}{180}\times 100\\\\=115\%[/tex]
So, the required percentage increase is 115%.
A bike shop purchased 12 mountain bikes wholesale for $ 189 . They want to make a 25 % on each bike. What is the sale price of the mountain bike after markup?
The cost of the Bike wholesale after the markup is $236.25
How to determine the cost after the markupFrom the question, we have the following parameters that can be used in our computation:
Bike wholesale = $189
Markup = 25%
The cost of the bike wholesale after the markup is then calculated as
Cost = Bike wholesale * (1 + markup)
Substitute the known values in the above equation, so, we have the following representation
Cost = 189 * (1 + 25%)
Evaluate the products
Cost = 236.25
Hence, the cost is $236.25
