Deanna borrowed $650 at 8% 0 simple interest. How much - 52 interest did she pay for 1 year?

Answers

Answer:

i = ($650)(0.08)(1) = $52

HOW DO YOU FIND RADIUS

Answers

Answer:

you can divide the diameter by 2 or divide the circumference by 2pi

Step-by-step explanation:

If the circumference of a circle is given:

Let the radius be r.Say, that the circumference is given as C.By using the formula,[tex]2\pi \: r = C \\ = > r = \frac{C}{2\pi} [/tex]So, to find radius of a circle when circumference is given, we have to divide the circumference with 2π. Then, we will get the radius of the circle.Note : You have to consider π as 22/7 or 3.14. Or the value will be given in the question.

If the diameter of a circle is given:

Let the radius be r.Let the diameter be D.By using the formula,2r = D[tex] = > r = \frac{D}{2} [/tex]Hence, if the diameter of a circle is given, we have to just divide the diameter with 2. Then we will get the radius of the circle.

Hope you could get an idea from here.

Do the values in the table represent a proportional relationship?

x 1 2 3 4
y 2.5 5 7.5 10

Select from the drop-down menu to correctly complete the statement.
All of the y-values a constant multiple of the corresponding x-values, so the relationship

Answers

Answer:

yes every values are increasing constantly by 2.5

Answer:

Step-by-step explanation:

Note that for each unit increase in x, y increases by 2.5. The constant of proportionality is therefore 2.5:

y = 2.5x

All of the y-values are a constant multiple of the corresponding x-values, so the relationship is a proportional one.

Answer:

avn= -8 + (n-1)(-7)

Step-by-step explanation:

arithmetic sequence formula= avn= av1 + (n-1)d

av1= first number in the sequence

d= common difference

n= the number of the term to find

The common difference is -7 so d=-7 and you plug it into the equation. The first number in the sequence is -8 so av1.

There is no specific n to find so it remains n.

I hope this helps! Let me know if this helps.

How many 1/8 tps can go into 1/8 cup?

Answers

Answer:

6 tps

Step-by-step explanation:

3 tsp = 1 tablespoons

16 table spoons = 1 cup

therefore 48 teaspoons = 1 cup

therefore 1/8th cup =6 teaspoons

Answer:

(1/8) cup = 6 U. S. teaspoons

Step-by-step explanation:

Do a quick Internet search. Type '1 cup = teaspoons" into the address line as tho' you were doing a search. Result: 1 cup = 48 U. S. teaspoons.

We want to know the teaspoon equivalent of 1/8 cup. To get this, multiply both sides of the above equation by 1/8:

(1/8) cup = (1/8)(48 U. S. teaspoons), or (1/8) cup = 6 U. S. teaspoons.

The tall gray buildings that make up the landscape of urban environments are becoming greener. They aren't getting a fresh coat of paint. Instead, their roofs are being covered in grass and small shrubbery. Many rooftops are beginning to look like nature parks. This change isn't just for fun. It is an attempt to add plants that can clean city air, absorb waste water, and generally add beauty to the city environment.Green roofs started in Europe and are now gaining a strong foothold in the United States. They are a way to add a little nature to the city environment. People plant vegetable gardens, flowers, and decorative grasses on their rooftops. One green roof in New York City is built on top of a processing and distribution facility. It is the largest green roof in the country. It has survived snow and rain, given employees a beautiful place for a lunch break, and helped clean the city air.It is more expensive to build a green roof than it is to lay asphalt or shingles. The basic green roof requires a frame and a waterproof membrane. It also requires gravel for drainage. Special material needs to be laid to retain moisture. Of course, soil for planting and a barrier that prevents roots from penetrating the building are also necessary materials for a green roof. Despite the extra cost, the trend is growing.The city of Chicago now has more green roofs than any other U.S. city. There are 7 million square feet of green roofs planted across the city. Toronto, Canada, is the first city in the western hemisphere to mandate green roofs on all new tall buildings. Green roofs are beneficial to the environment and the cities that build them. A recent study in Toronto suggested that if 75 percent of the flat roofs were greened, the city could save $37 million a year on storm water management and energy bills. If this is true, we may begin to see more and more green added to cities around the world.Why does the author include the point that there are 7 million square feet of green roofs planted across the city of Chicago?A. To paint a picture of what the green roofs in Chicago look like.B. To exaggerate how many green roofs there are in the city.C. To show that Chicago has not accepted the green roof trend.D. To prove that Chicago has the most green roofs in the United States. square pyramid has _______ spaces Question locate in image show working one kilogram of cheese costs 9.48chris buys 650 g of this cheese work out how much chris pays Two handymen can do a home repair in 2 hours if they work together.
