Answer:

A) on edge2020

Step-by-step explanation:

The greatest amount of time when they worked together is 2.4 hours.

Algebra is the part of mathematics that helps represent problems or situations in the form of mathematical expressions.

Given:

Randy at most 4 hours to clean the offices.

Trey at most 6 hours to clean the offices.

If they work together, they will clean

1/4 + 1/6 = 5/12 of the offices.

Let x be the greatest amount of time it would take them to clean the offices together.

Thus,

5*x/12=1

5x=12

x= 12/5

x= 2.4 hours.

Answer: Slope = -7/5

=========================================================

Explanation:

Pick any two rows you want. I'll select the first two rows.

Each row represents an (x,y) point

The first row means (-8,55) is one point and the second row means (2,41) is another point.

Use these two points in the slope formula to get

m = (y2 - y1)/(x2 - x1)

m = (41-55)/(2- (-8) )

m = (41-55)/(2 + 8)

m = -14/10

m = -7/5 is the slope

The negative slope means the line goes downhill as you move from left to right.

Specifically, every time it drops 7 units the line moves over to the right 5 units.

slope = rise/run = -7/5

rise = -7, negative rise means we go down 7 spaces

run = 5 means we move to the right 5 spaces

Absolute value is the distance on a number line. In other words, a number with absolute value will always be positive.

Answer:

Absolute value means to remove any negative sign in front of a number, and to think of all numbers as positive or zero.

Step-by-step explanation:

Given data : 68 , 69 , 71 , 71 , 71 , 73 , 74 , 75 , 75 , 78

N ( total number of observation ) = 10

Finding the position of median

[tex] \boxed{ \sf{median = { (\frac{n + 1}{2} )}^{th \: item} }}[/tex]

[tex] \dashrightarrow{ \sf{median = { (\frac{10 + 1}{2} )}^{th \: item}}} [/tex]

[tex] \dashrightarrow{ \sf{median = {( \frac{11}{2}) }^{th \: item}} }[/tex]

[tex] \dashrightarrow{ \sf{ median = {5.5}^{th \: item}}} [/tex]

[tex] \sf{ {5.5}^{th} }[/tex] item is the average of 5 th and 6 th items.

Answer:

(x - 8)(x + 4)

Step-by-step explanation:

We need to find something that multiplies to 32 and adds up to 4.

The 2 special numbers would be -8 and 4.

-8(4) = -32

-8 + 4 = -4

We then simply write out the factored form:

(x - 8)(x + 4)

Answer:  (x+4)(x-8)    

Step-by-step explanation:

x^2 - 4x -32         Find two numbers that their product is -32 and their sum is -4. The numbers -8  and 4 will work out because -8 times 4 is -32 and -8 plus 4 is -4.

Now rewrite the whole polynomial as

x^2 +4x -8x -32     Now group them  

(x^2 +4x)  (-8x -32)    Now factor each side

x(x +4)   -8(x +4)         factor out x+4

(x+4)(x-8)  

Answer:

37/6

Step-by-step explanation:

The improper fraction is 37/6.

What is improper fraction?

An improper fraction is defined as a fraction whose numerator is greater than the denominator. Suppose, x/y is an improper fraction, such that x > y. It is therefore, the improper fraction is always greater than one.

Fractions have two parts, numerator and denominator. If  ⅓ is a fraction, then 1 is the numerator, and 3 is the denominator. An improper fraction has a numerator greater than the denominator. For example, 3/2 is an improper fraction.

Given fraction is [tex]6\frac{1}{6}[/tex]

firstly we will multiply 6 by 6 and then we will add 1

(36+1)/6

= 37/6

Which is improper fraction.

Answer:

The answer is B. 0

Step-by-step explanation:

If the problem is d + (-d), then the answer is 0. Suppose that d = 7. Then it would be 7 + (-7), which is 0. You can't get any other number from that equation unless you do d + d or d - d.

Answer:

69

Step-by-step explanation:

Perimeter = sum of all sides of a regular polygon = the number of sides*length of a side

Length of a side of the given regular hexagon = 3x + 5

Perimeter of hexagon = 6(3x + 5) = 6(3x) + 6(5) = 18x + 30

Length of a side of the given regular pentagon = 4x - 1

Perimeter of pentagon = 5(4x - 1) = 5(4x) - 5(1) = 20x - 5

Since we are told that the perimeter of the regular hexagon is the same as that of the regular pentagon, therefore:

18x + 30 = 20x - 5

Solve for x.

Subtract 20x from both sides

18x + 30 - 20x = 20x - 5 - 20x

-2x + 30 = -5

Subtract 30 from both sides

-2x+ 30 - 30 = -5 - 30

-2x = -35

Divide both sides by -2

x = -35/-2

x = 17.5

Length of a side of pentagon = 4x - 1

Plug in the value of x

4(17.5) - 1 = 70 - 1 = 69

length of a side of the pentagon = 69

x=203/18

Step-by-step explanation:

convert the decimal into a fraction

203/50/x = 9/50 / 1/2

simply the complex fraction:

203/50x = 9/25

cross multiply

450x = 5075

divide both sides by 450:

x= 203/18

Answer:

X=11.2778

Step-by-step explanation:

4.06/X=0.18/0.5

cross multiply

0.18×X=4.06×0.5

0.18X=2.03

divide both sides by 0.18

0.18X/0.18=2.03/0.18

it becomes

X=2.03/0.18

X is therefore 11.2778
