Answer 1
y=-3x+7

Because
y=mx+b

m= slope (3/-1 which simplifies to -3)
x
b= y-intercept (y-intercept is where the line hits the y axis, which that line hits the line at the y intercept of 7

so when u put it into an equation, you have your answer of:
y=-3x+7

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.

The value of the expression at y = 2.5 is 6.25.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

y²

Substitute y = 2.5

= y²

= 2.5²

= 2.5 x 2.5

= 6.25

Thus,

The value is 6.25.

B.

3/4 is equal to .75 in decimal form.
5.75 = 5 & 3/4 in decimal form
B is the correct answer

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
