3. What is the greatest area possible for a rectangle with a perimeter of 28 units?

4. What are the dimensions of the rectangle with the largest area?

5. Explain how you found this on the table.

6. Explain how you found this on the graph

7. What is the maximum area that your dog will have to run around in your fenced yard?

Answer:

y=1/2x-3

Step-by-step explanation:

First, let's put the line into slope intercept form

2y+4x=12

subtract 4x from both sides

2y=-4x+12

divide by 2

y=-2x+6

the slopes of perpendicular lines are negative and reciprocal. If you multiply the slopes of the lines together, the result is -1. Therefore, to find the slope of the perpendicular line, use this formula:

-2m=-1

divide by -2

m=1/2

so the slope of the perpendicular line is 1/2

here is the new line so far:

y=1/2x+b (b is a place holder)

now, since the line passes through the point (8,1), it means that (8,1) is a solution of the line. So we can substitute it into the equation

1=1/2(8)+b

1=4+b

subtract 4 from both sides

-3=b

so the line is y=1/2x-3

Hope this helps!

Step-by-step explanation:

Answer: The answer is 530.66

Step-by-step explanation:

I took the test and 81.64 is wrong, It's 530.66

The area of the road sign in the circular shape of diameter 26 inches is closest to 530.66 in².

The area of the circle is pi times the square of the radius of a given circle.

The area of the circle = [tex]\pi r^2[/tex]

A road sign "No Parking" is given in a circular shape of diameter 26 inches. we need to find the area of the sign.

The diameter of the circle is 26 in so, the radius will be half of the diameter which will be 13 in.

Now, the area of the circle =  [tex]\pi r^2[/tex]

the area of the circle = 3.14 × 13 × 13

                                   =  530.66 in²

Hence, the area of a circle of diameter 26 inches is equal to 530.66 in².

#SPJ3

Answer:

Scalene and acute

Step-by-step explanation:

(I know there isnt any real problem here to solve, but heres a tip on how to solve greatest to least with decimal problems)

1. Just because a number looks big, doesn't mean it is big

Example: 1.00000000000001 < 1.1

just look at the numbers ^ and dont just hastily read it over assuming that 1.1 is smaller because it "has less digits"

2. Negative numbers are... opposite. and they are less than positive numbers

-3.4 > -4.1

Why is this? Well, if you look on a line, with the point 0 in the middle, you can see that -3.4 is not as far away from 0 as -4.1 is. So the idea is to apply opposite logic for negative numbers

I hope these tips helped!! :D

a) A student travelling to school on public transport: 15/52 or 0.231

b) A student walking to school: 16/52 or 0.308

c) A student not cycling to school: 43/52 or 0.827

Step-by-step explanation:

Total people = 52

Travel Method          Frequency

Public Transport           12

Car                                 15

Cycle                               9

Walk                                16

Find the relative frequency of.

The formula used will be: [tex]Relative\:Frequency=\frac{Given\: Frequency}{Size\: of\: sample \:space}[/tex]

a) A student travelling to school on public transport:

Given Frequency: 12

Size of sample space: 52

Apply formula: [tex]Relative\:Frequency=\frac{Given\: Frequency}{Size\: of\: sample \:space}[/tex]

Fraction = 12/52

Decimal = 0.231

b) A student walking to school

Given Frequency: 16

Size of sample space. 52

Apply formula: [tex]Relative\:Frequency=\frac{Given\: Frequency}{Size\: of\: sample \:space}[/tex]

Fraction = 16/52

Decimal = 0.308

c) A student not cycling to school.

We will consider all students except those who cycle.

12+15+16 = 43

Given Frequency: 43

Size of sample space. 52

Apply formula: [tex]Relative\:Frequency=\frac{Given\: Frequency}{Size\: of\: sample \:space}[/tex]

Fraction = 43/52

Decimal = 0.827

Answer:

126

Step-by-step explanation:

Angle SRW is supplementary to (2x + 18)º and (3x)º, that is, they add up to 180º.

Finding angles in function of X:

Since angles (2x + 18)º and (3x)º are opposite by vertex R, they have the same measure. So

[tex]3x = 2x + 18[/tex]

[tex]x = 18[/tex]

So

[tex]3x = 3(18) = 54[/tex]

Angle SRW:

Supplementary with 54. So

54 + SRW = 180

SRW = 180 - 54 = 126

So 126 is the answer.

Answer:

cot 5^/6

Step-by-step explanation:

The equivalent expression for tan(5π/6) will be cot(5π/6) based on the above relationship

The tan of a function is determined from the ratio of sine of the angle to the ratio of cosine of the angle.

tanθ = sinθ/cosθ

This is known as cotangent, which is reciprocal of a tangent.

Cotθ =  1/tanθ = cosθ/sinθ

Thus, the equivalent expression for tan(5π/6) will be cot(5π/6) based on the above relationship

Step-by-step explanation:

Answer:

84 yd2

Step-by-step explanation:

Answer:

x + 3y – 2z = 8

-x – 2y + z = 12

2x – 7y + z =7

this answer is fake

Step-by-step explanation:

x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1

Answer:

AB equals 25

Step-by-step explanation:

1( you take ED and the 5 and say of 5.

2( then you count all the letters that stand for numbers and count them.

3) after you count them how many ever there are then you take that number which was 5 too.

4(after you find that number which is number 5 you multipliy 5 and 5.

5(after you multipliy then you should get 25 because 5x5 is 25.
