Answer:

5/2, or 2.5 miles

Step-by-step explanation:

Monday - 3/4 mile

Wednesday - 1/2 mile

Thursday - 2/3 mile

Saturday - 7/12 mile

Take the common denominator and add (in this case it will be 12)

9/12 + 6/12 + 8/12 + 7/12 = 30/12 = 5/2

Gio walked 2.5 miles

Answer:

She walked 2 7/12 miles.

Step-by-step explanation:

To start, we have to make sure we can add each fraction. One multiple they all have in common is 12. So we will change the denominator to 12. Remember, what you do to one side you have to do to the other!
To turn 3/4 into a 12, multiply by 3. 3x3 is 9 and 4x3 is 12 so 9/12.
To turn 1/2 into a 12, multiply by 6. 1x6 is 6 and 2x6 is 12 so 6/12.
To turn 2/3 into a 12, multiply by 4. 2x4 is 8 and 3x4 is 12 so 8/12.
And 7/12 is already in 12ths.

From there, we have to add the numerators.
9 + 6 + 8 + 7 = 31.
Now we have 31/12. We have to simplify this into a mixed number.
31 goes into 12 two times.
So we have 2 and 7/12 miles.

a rhombus with a base of 18 centimeters and a height of 15 centimeters

What is the area of the rhombus?

66 cm2
132 cm2
135 cm2
270 cm2

Answers

Answer:

270 cm²

Step-by-step explanation:

The area of a rhombus can be calculated using the formula Area = base * height. In this case, the base is 18 centimeters and the height is 15 centimeters. So the area of the rhombus is:

Area = 18 * 15

So, Area = 270 cm².

The area of the rhombus is 270 cm².

The area of the rhombus given is; 279 cm².

What is the area of the rhombus?

The area of a rhombus can be calculated using the formula;

Area = base * height.

Given that the base is 18 centimeters and the height is 15 centimeters. So the area of the rhombus is:

Area = 18 x 15

So, Area = 270 cm².

Therefore, area of the rhombus is 270 cm².

In a class in a middle school, there were 80 students. 30 percent were girls. How many of the class were boys. Awnser in percents.

Answers

Answer:

In a class of 80 students 30 are girls.

To Find:

The percentage of girls in the class is?

Solution:

The given problem can be solved using the concepts of percentages.

1. The total number of students in the class is 80, 30 are girls of the 80 members.

2. Percentage is given by the formula,

=> Percentage = (Favorable numbers x 100)/Total numbers,

3. Using the formula mentioned above the percentage can be calculated,

=> Percentage of girls = (30x100)/80,

=> (30x100)/80,

=> (3x100)/8,

=> (3x25)/2,

=> 75/2 = 37.5%.

Step-by-step explanation:

Answer:

70%

Step-by-step explanation:

If 30% of the class were girls, then 70% of the class must be boys (since 30% + 70% = 100%).

To find out how many students this represents, we can use the following formula.

70/100 * 80 = 56

So there were 56 boys in the class.

To express this as a percentage, we can calculate what percentage of the class the boys represent.

56/80 * 100 = 70%

Therefore, 70% of the class were boys.

A local jewelry store sells class rings, which it purchases for $60 each. The store engraves a name and date on the ring and sells it using a markup rate of 340%.

What is the markup rate in decimal form?

The markup rate is the constant of proportionality in the equation y=kx
. Write an equation that can be used to find the markup on the cost x
of a ring.

Use the equation to find the markup amount by substituting the cost of a ring for x

.What is the retail price of a ring?

During graduation week, the store is going to reduce the price to $184.80.

Calculate what percent the sale price is of the retail price.

Think of the retail price of the ring as 100%. How does the sale price compare to the retail price? What does this tell you about the markdown rate?

What is an equation in the form y=kx
that relates the sale price to the retail price x
?

Answers

The markup rate in decimal form is 3.40 (340% is equivalent to multiplying by 3.40).

The equation that can be used to find the markup on the cost x of a ring is: Markup = 3.40x.

If the store purchases the rings for $60 each, the markup amount would be:

Markup = 3.40 x $60 = $204

The retail price of a ring would be the cost plus the markup amount:

Retail price = Cost + Markup = $60 + $204 = $264

During graduation week, the store is reducing the price to $184.80. To find what percent the sale price is of the retail price:

Sale price percentage = (Sale price / Retail price) x 100%
Sale price percentage = ($184.80 / $264) x 100% = 70%

The sale price is 70% of the retail price. This means that the markdown rate is 30%.

An equation in the form y=kx that relates the sale price to the retail price x is:

Sale price = k x Retail price

To find k, we can use the information given in the problem that the sale price is 70% of the retail price:

0.70 Retail price = k x Retail price

Simplifying this equation, we get:

k = 0.70

Therefore, the equation in the form y=kx that relates the sale price to the retail price x is:

Sale price = 0.70 x Retail price

A restaurant uses c cups of flour for baking rolls and 12 cups of flour for baking pies each day. Use the Distributive Property to write an expression for how much flour the restaurant uses in seven days.

Answers

Answer:

7c + 84

Step-by-step explanation:

To find how much flour the restaurant uses in seven days, we need to multiply the amount of flour used per day by 7. We can use the distributive property to simplify this expression by factoring out the common factor of "c + 12":

Flour used in 7 days = 7(c + 12)

Expanding the expression, we get:

Flour used in 7 days = 7c + 7(12)

Simplifying, we get:

Flour used in 7 days = 7c + 84

Therefore, the expression for how much flour the restaurant uses in seven days is 7c + 84.

Solution

X=30
Other guy didn’t explain so here it is

The two angles are equal as they are vertically opposite. So, we will show that algebraically as
5x-30 = 4x

Now we solve the equation.

Subtract 4x from both sides to get 5x-30-4x=0

Now add 30 to both sides to get 5x-4x=30

Now do 5x-4x=x
X=30

We have more than 34 megacities now (cities with a population over 10 million people) and may see 41 megacities by 2030. There are environmental and social advantages to concentrating development, and these include access to services, health care, and education. It is easier to develop infrastructure in a more compact geographic area; infrastructure includes distribution of utilities (water, electricity, wastewater) and transportation (road network and mass transit). However, there are many problems associated with urbanization, such as increased water and air pollution, increased impervious surfaces, and higher incidence of disease. So the challenge presented to urban developers is how to build these urbanized areas to enhance the advantages and to minimize environmental and social problems.Refer to Smart Growth and New Urbanism websites to describe some of the strategies urban geographers employ to develop cities that either improve or do not substantially harm the environment, and enhance the social aspects of the city (increasing the sense of community and equity). Cities policies can also address climate issues by reducing carbon emissions to the atmosphere.For this discussion, please address the following prompts:Describe at least four (4) strategies that address these issues above, and provide an example for at least one of these strategies.Many cities are currently implementing sustainable policies.
