A summer camp has 720 ft of float line with which to rope off three adjacent rectangular areas of a lake for swimming lessons, one for each of three levels of swimming ability. A beach forms one side of the swimming areas. Suppose that the width of each area is x feet. Answer parts a) through c).
Step-by-step explanation:
Kindly find attached a detailed image to better understand the solution to this problem.
given that the total length of the line is 720ft
and also the line is divided into three sections
This means that the line will also be divided into three parts
720/3= 240feet so that a section will have two sides that are 240ft since the section forms a rectangular shape.
now for the other two sides
the total length of the rope is = one length size of the rectangle+ 4 width size of the rectangle
one width size of the rope is x
then 4 width size is 4x
720=length of rectangle +4x
length of rectangle= 720-4x
area of a rectangle is =length *width
area of rectangle is = (720-4x)*x
Hence the function A= (720-4x)x can be used to solve for the area of the rectangle.

Find cosα given that sinα = 5/13 and α is in quadrant II
Answer:
cos α = - [tex]\frac{12}{13}[/tex]
Step-by-step explanation:
Since α is in second quadrant then cosα < 0
Using the identity
sin²α + cos²α = 1 then
cosα = - [tex]\sqrt{1-sin^2\alpha }[/tex]
= - [tex]\sqrt{1-(\frac{5}{13})^2 }[/tex]
= - [tex]\sqrt{1-\frac{25}{169} }[/tex]
= - [tex]\sqrt{\frac{144}{169} }[/tex]
= - [tex]\frac{12}{13}[/tex]

Which equation represents the graphed function?
A. y = -2x + 3
B. y = 2x + 3
C. y=1/2x+3
D. y=-1/2x+3
Answer:
y= - 2x+3
Step-by-step explanation:
3 is our start possition
the number before the x is the rise over run
so we would "rise" (vertical) 2 but since it has a - it will be going the oppisite direction then our run would be 1 going over horizenly 1 block
A rectangle is 45 cm on one side and 6 cm on another side. What is the perimeter?

Solve for r 5(r-10)=-51
Answer:
r=−1/5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(r−10)=−51
(5)(r)+(5)(−10)=−51(Distribute)
5r+−50=−51
5r−50=−51
Step 2: Add 50 to both sides.
5r−50+50=−51+50
5r=−1Step 3: Divide both sides by 5.
5r/5=−1/5
r=−1/5
Answer:
r = - ¹/₅ or -0.2Step-by-step explanation:
5(r - 10) = -51
5r - 50 = -51
5r = -51 + 50
5r = -1
r = - ¹/₅ or 0.2

Are lines m1 and m2 parallel? Explain Yes, because line m1 has a slope of -\frac{5}{2}− 2 5 and m2 has a slope of -2 No, because lines m1 and m2 have the same slope of -\frac{5}{2}− 2 5 No, because line m1 has a slope of -\frac{5}{2}− 2 5 and m2 has a slope of -2 Yes, because lines m1 and m2 have the same slope of -2 Item at position 2 2
Answer:
Yes, because lines m1 and m2 have the same slope of -2
Step-by-step explanation:
For given two lines L1 and L2 with slope m1 and m2 respectively, the condition for the two lines to be parallel is for the two equations to have the same slope. If m1 = m2, the meaning is that the line L1 and L2 are parallel to each other no matter the equation of the lines in question.
The general equation of a line is y = mx+c where;
m is the slope and c is the intercept.
Even though we are not given the equation of both lines, the base line is that for two lines to be parallel to each other, they must have the same slope.
The correct option is therefore "Yes, because lines m1 and m2 have the same slope of -2"

were 102 students at the dance. How many boys and how many girls were
present at the dance? Define two variables and then set up two equations. Solve
using either substitution or elimination.
Answer:
58 girls
44 boys
Step-by-step explanation:
102 divided by 2= 51 have to divide, 14 divided by 2 = 7
51 - 7= 44
51 + 7= 58
58 + 44= 102
according to my calculations hope i helped ^_^
and also 58 -44= 14 is the difference between them

When the function y=x is changed to y=|x|, how is the graph affected?
A. All points for x 0 are reflected over the line y=x.
B. All points for x 0 are reflected over the line y=x.
D. All points for x > 0 are reflected over the x-axis.
Answer:
First, the function:
y = x
Is:
Positive if x > 0
Negative if x < 0
Now, on another hand, the function y = IxI is:
Positive if x < 0
Positive if x > 0.
Then the only part that changes is the negative side of the domain, and the thing that changes is the sign (the change of sign is equivalent to a reflection over the x-axis or the line y = 0".
Then the correct option is:
"All points for x < 0 are reflected over the x-axis"
I suppose that this is option C, the missing one.
find the value of x
The answer is 40.
I need to show my work
Answer:
(2x+7)° + (5x+4)° + 69° = 360°
=> 2x + 7 + 5x + 4 + 69 = 360
=> 7x + 80 = 360
=> 7x = 360 – 80
=> x = 280/7
=> x = 40
Answer:
x=40
Step-by-step explanation:
(2x+7)*+(5x+4)*+69*=360* (360* because its a circle)
7x+80=360 (combine like terms)
- 80 -80 (minus 80 both sides)
7x=280 (divide 7 both sides)
x=40
