Clare paid 50% more for her notebook than Priya paid for hers. Priya paid x for her notebook and Clare paid y dollars for hers. Select an equation that represents the relationship between y and x.

Answers

Y = x - 50 percent !

The equation y = 1.5x represents the relationship between y and x.

What is an equation?

When two mathematical expressions are equivalent to one another in a system of variables, the system is called an equation.

Given that,

Amount paid by Priya for her notebook = x,

Amount paid by Clare for her notebook = y.

Since, Clare paid 50% more for her notebook than Priya.

The equation for the relationship between y and x can be written as,

y = 1.5 x

The required equation is y = 1.5x.

Matilda has been studying exponential functions in her algebra class and has started to notice a pattern.

For some exponential functions, when she plugs in larger and larger numbers, she gets larger and larger numbers. For others, she gets smaller and smaller numbers. And for some, plugging in larger and larger numbers actually gets her closer and closer to one number.

Which of the following exponential functions get closer and closer to one value as you plug-in larger and larger values for x?

A truck can be rented from Company A for ​$90 a day plus ​$0.30 per mile. Company B charges ​$40 a day plus ​$0.40 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
At _____ nothing ​miles, the rental costs are the same from either company.

Answers

Answer

The answer is 500 miles

Step-by-step explanation:

So, 500 x 0.40 is equal to $200. And if we add the $40 a day fee it's now $240.

And the other company charges $0.30 a mile. So that equation is:

500 x 0.30 = $150 plus the $90 fee is $240.

The reason B is the right answer is because 3/4 of a quarter is 75 and if you change 0.75 into a fraction (75/100) and divide by 25 you have 3/4. So therefore the answer is 5 3/4km

Write an equation to represent the sum modeled in the following number line.

Answers

Answer:

-6/4

Step-by-step explanation:

The diagram shows the layout of the township playground. The playground committee is ordering rubber mulch to cover the playground surface.

A playground is made up of a rectangle and a triangle. The rectangle has a base of 40 feet and height of 25 feet. The triangle has a base of 22 feet and height of 20 feet.

One ton of mulch will cover 122 square feet at the needed depth. How many tons of mulch should the committee order?

The area of the rectangular section is
ft2.
The area of the triangular section is
ft2.
The total area of the playground is
ft2.
The committee should order
tons of mulch.

Answers

Step-by-step explanation:

Okay, so to figure out the area of a rectangle, the equation is base times height.

40*25=1000

So the area of the rectangle is 1000 square feet.

The formula for the area of a triangle is base times height divided by 2.

22*20=440

440/2=220

So the area of the triangle is 220 square feet.

Therefore, combining this, the total area of the playground is 1,220 square feet.

Since one ton of mulch covers 122 square feet, divide the total area of the playground by the amount 1 ton covers.

1220/122=10

You would need 10 tons of mulch to cover the playground.

a)The area of the rectangular section is 1000 ft2.

b)The area of the triangular section is 220 ft2.

c)The total area of the playground is 1220 ft2

d)The committee should order 10 tons of mulch.

What are the areas of a rectangle and a triangle?

The area of a rectangle is the product of length and breadth while the area of a triangle is the half of the product of the base and the height.

The area of the rectangular part = 40*25 =1000 square feet

The area of the triangular part = 0.5*22*20 =220 square feet

Total area to cover =1000+220 =1220 square feet

Given that 1 ton of mulch will cover 122 square feet

Or, 122 square feet area will be covered by= 1 ton of mulch

So, 1 square feet area will be covered by= (1/122) ton of mulch

So, 1220 square feet area will be covered by=(1/122)*1220 =10 tons of mulch.

Thus, a)The area of the rectangular section is 1000 ft2.

b)The area of the triangular section is 220 ft2.

c)The total area of the playground is 1220 ft2

d)The committee should order 10 tons of mulch.
