A sprinkler can water between 1 and 130 square yards of a lawn. The length L in inches of rotating pipe needed to water A square yards is given by the function L=119.75 square root of A. How much area can be watered if the length of the pipe is 600, 900, or 1,000 inches long?
Answer:
[tex]25.1\ \text{inches}^2[/tex]
[tex]56.5\ \text{inches}^2[/tex]
[tex]69.7\ \text{inches}^2[/tex]
Step-by-step explanation:
The length of the pipe is given by the function
[tex]L=119.75\sqrt{A}[/tex]
where A is the area
[tex]A=(\dfrac{L}{119.75})^2[/tex]
For [tex]L=600\ \text{in}[/tex]
[tex]A=(\dfrac{600}{119.75})^2\\\Rightarrow A=25.1\ \text{inches}^2[/tex]
Area watered when L = 600 inches is [tex]25.1\ \text{inches}^2[/tex]
For [tex]L=900\ \text{in}[/tex]
[tex]A=(\dfrac{900}{119.75})^2\\\Rightarrow A=56.5\ \text{inches}^2[/tex]
Area watered when L = 900 inches is [tex]56.5\ \text{inches}^2[/tex]
For [tex]L=1000\ \text{in}[/tex]
[tex]A=(\dfrac{1000}{119.75})^2\\\Rightarrow A=69.7\ \text{inches}^2[/tex]
Area watered when L = 1000 inches is [tex]69.7\ \text{inches}^2[/tex]

Step-by-step explanation:
(-2c + 5) – (6.3c + 20) -
I need the difference
Answer:
-2cd-16-6.3c
Step-by-step explanation:
1) Remove Parentheses -2cd+5-6.3c-20-1
2) Collect like terms -2cd+ (5-20-1)-6.3c
simplify and that would give you -2cd-16-6.3c hope that helps
The difference of (-2c + 5) – (6.3c + 20) is -8.3c -15 .
What is subtraction?Mathematical operation is subtraction. It is employed to eliminate terms or expression's objects.
The given expression is (-2c + 5) – (6.3c + 20).
(-2c + 5) – (6.3c + 20)
= -2c-6.3c +5 - 20
= -8.3c -15
Therefore, the subtraction of (-2c + 5) and (6.3c + 20) is -8.3c -15.

factorise 3abc+6a²b pleaze with step too
Answer:
3ab(c+2a)
Step-by-step explanation:
Given data
3abc+6a²b
we can see that 3, a, and b are common between the two terms
so let us factor them out
3ab(c+2a)
Hence the factored form is
3ab(c+2a)
Can someone help me with these definitions?
Answer:
Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000. So 4000 can be written as 4 × 10³. This idea can be used to write even larger numbers down easily in standard form. Small numbers can also be written in standard form.
Factored form, the product of a constant and two linear terms: or. The parameters and are the roots of the function (the x-intercepts of the graph ). Converting a quadratic function to factored form is called factoring.
The y -intercept of a graph is the point where the graph crosses the y -axis. (Because a function must pass the vertical line test , a function can have at most one y -intercept . ) The y -intercept is often referred to with just the y -value.
The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis. and vertex is
In geometry, a vertex (in plural form: vertices or vertexes), often denoted by letters such as, is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices.

The distance Jane jogs in 20 minutes is 8 miles. At this rate, how many miles will he run in 60 minutes?
Answer: the answer is 24 miles
Step-by-step explanation:
Answer:
24 miles
Step-by-step explanation:
the ratio is 20:8
If we wanna find the ratio for 60 mins, you have to multiply both sides by three.
Then, we get 20/8 = 60/24
So, Jane jogged 24 miles in sixty minutes

the equations x + 4 = y and 2x + 2 = y form a system that has ...?
A. one solution
B. no solution
C. an infinite number if solutions
Answer:
A. One solution
Step-by-step explanation:
We are given a system of equations and are asked to find whether it has a certain solution.
y = x + 4
2x + 2 = y
Since both equations end with y, we can substitute them from back to back.
x + 4 = 2x + 2
Subtract 2 from both sides :
x + 2 = 2x
Subtract x from both sides :
x = 2
Solve for y now that you have x by subtituting x with the value.
(2) + 4 = y
2(2) + 2 = y
6 = y
6 = y
Therefore this means that the system of equations is one solution because it intersects at one point (2, 6).

Answer:
A
Step-by-step explanation:
in a right triangle, the longest side (across from the right angle) is the hypotenuse (denoted as 'c')
the legs are denoted as 'a' and 'b'
the Pythagorean Theorem allows you to find the missing side using this formula:
a² + b² = c²

What is the center of the circle for this equation:
x² + (y - 9)² = 25
Answer:x=√−y2+18y−56 or x=−√−y2+18y−56
Step-by-step explanation:
x2+(y−9)2=25
Step 1: Add -y^2 to both sides.
x2+y2−18y+81+−y2=25+−y2
x2−18y+81=−y2+25
Step 2: Add 18y to both sides.
x2−18y+81+18y=−y2+25+18y
x2+81=−y2+18y+25
Step 3: Add -81 to both sides.
x2+81+−81=−y2+18y+25+−81
x2=−y2+18y−56
Step 4: Take square root.
x=√−y2+18y−56 or x=−√−y2+18y−56
Answer:
x=√−y2+18y−56 or x=−√−y2+18y−56

Divide 2m in the ratio 9-1
Answer:
Step-by-step explanation:
First, add up the two numbers in the ratio to get 8. Next divide the total amount by 8, i.e. divide £40 by 8 to get £5. £5 is the amount of each 'unit' in the ratio.
To calculate the ratio of an amount we divide the amount by the total number of parts in the ratio and then multiply this answer by the original ratio. We want to work out $20 shared in the ratio of 1:3.
