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.

3/4 is equal to .75 in decimal form.
5.75 = 5 & 3/4 in decimal form
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
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?

True or false: There is a constant amount of carbon on Earth. Carbon cannot be made or destroyed. It can only move between different carbon reservoirs.
Answers
answer:
true Because Earth is a closed system, the amount of carbon on the planet never changes. However, the amount of carbon in a specific reservoir can change over time as carbon moves from one reservoir to another. For example, some carbon in the atmosphere might be captured by plants to make food during photosynthesis

the population of center city is modeled by exponential function f, where x is the number of years after the year of 2015. the graph of f is shown on the grid. which inequality best represents the range of f in this situation?
Answers
Answer:
the Answer is B) y >= to 250,000
The requried inequality that represents the range of the function shown is f(x) ≥ 250,000.
What is the range?The range is a key concept in the study of sets and it defines as the set of values that come out to an outcome for a certain mathematical operation.
Here,
As mentioned in the question, the population of the central city is modeled by exponential function f, where x is the number of years after the year of 2015.
As the graph starts from 0 (as the year 2015) and goes to an unknown end implying over the x-axis which is its domain. Corresponding to this, the range starts from 250000 on the y-axis and goes to infinity.
Thus, the requried inequality that represents the range of the function shown is f(x) ≥ 250,000.

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.
What do all these numbers have in common ?
