Answer:
10 m
Step-by-step explanation:
Area of a square
[tex]A=s^2[/tex]
where s is the side length.
If the area of the floor is 6 m²:
[tex]\begin{aligned}A&=s^2\\\implies 6&=s^2\\\sqrt{6}&=\sqrt{s^2}\\s&=\sqrt{6}\end{aligned}[/tex]
Therefore, the side length of the square is √6 m.
Perimeter of a square
[tex]P=4s[/tex]
where s is the side length.
Substitute the found value for s into the formula to find the perimeter:
[tex]\begin{aligned}P&=4s\\\implies P&=4 \cdot \sqrt{6}\\P&=4 \sqrt{6}\\P&=9.79795897...\\ P&=10 \sf \;m\;(nearest\:integer)\end{aligned}[/tex]
Therefore, the perimeter is 10 m to the nearest integer.

Nakeisha needs to order some new supplies for the restaurant where she works. The restaurant needs at least 566 forks. There are currently 188 forks. If each set on sale contains 8 forks, which inequality can be used to determine xx, the minimum number of sets of forks Nakeisha should buy?
The inequality that can be used to determine the minimum number of set of forks Nakeisha should buy is xx ≥ (566 - 188) / 8.
What is the minimum set of forks she should buy?The first step is to determine the appropriate inequality signs that can be used.
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
The inequality sign that would be used is ≥.
The form of the inequality is: xx ≥ (least number of forks needed - forks they current have) / number of forks in one set

Answer:

Step-by-step explanation:
Which of the following equations describes the line shown below? Check allthat apply.(-5,6)(-1,-1)
Options E and F are the correct options
Here, we need to get the equation of the line that passes through the two points given
Mathematically, the equation of a line can be generally expressed as ;
y = mx + c
where m is the slope of the line and c is the y-intercept of the lien ( where it crosses the y-axis)
To get the slope m , we are goint to use the formula below;
[tex]\begin{gathered} m=\frac{y_2-y_1}{x_{2\text{ - }}x_1} \\ \\ x_{1\text{ }}=-5,x_2=-1,y_1\text{ = }6,y_2\text{ = -1} \end{gathered}[/tex]Substituting these values into the slope equation , we have
m = (-1-(6))/(-1-(-5)) = -7/4
The equation is now in the form;
y = -7x/4 + c
what is left is to get the y-intercept
We can get the value of the y-intercept by substituting for x and y using any of the points
Let us use the second point
Here, x = -1 and y = -1
Thus;
-1 = -7(-1)/4 + c
-1 = 7/4 + c
c = -1-7/4 = -11/4
So the complete equation of the line is;
y = -7x/4 - 11/4
To properly answer the questions, we need the forms in the options that looks like or can be manipulated arithmetically to look like what we have as our answer
We proceed with each of the options one after the other to see if they can be written in the form of our answer
Option A
y - 5 = -7/4 ( x + 6)
Opening the bracket and evaluating;
y - 5 = -7x/4 - 42/4
y = -7x/4 -42/4 + 5
y = -7x/4 -22/4
we can see this is not a correct option
Option B
y - 6 = -4/7 (x + 5)
Multiply through by 7
7y - 42 = -4x - 20
7y = -4x - 20 + 42
7y = -4x + 22
divide through by 7
y = -4x/7 + 22/7
We can see this is incorrect also
Option C
y - 1 = -4/7(x-1)
Multiply through by 7
7y - 7 = -4x + 4
7y = -4x + 4 + 7
7y = -4x + 11
divide through by 7
y = -4x/7 + 11/7
This is incorrect too
Option D
y + 1 = -4/7 ( x + 1)
Multiply through by 7
7y + 7 = -4x - 4
7y = -4x -4 -7
7y = -4x - 11
y = -4x/7 - 11/7
This is incorrect also
Option E
y - 6 = -7/4 (x + 5)
Multiply through by 4
4y - 24 = -7x - 35
4y = -7x - 35 + 24
4y = -7x -11
y = -7x/4 - 11/4
This is a correct option
Option F
y + 1 = -7/4 ( x + 1)
Multiply through by 4
4y + 4 = -7x - 7
4y = -7x - 7-4
4y = -7x - 11
y = -7x/4 - 11/4
This is a correct option too

HELP PLEASE AND THANK YOUMelinda and Paul ran in a marathon. this this graph shows the relationship between the distance and the time they each run. Melinda ran a constant speed of 5 mph. Paul ran at a ____ constant speed than Melinda. an equation that could represent the relationship between Paul's distance and his time is y = _____x, where x is the time in hours and y is the distance in miles Paul ran.THE ANSWER CHOICES ARE 1) FASTER OR SLOWER 2) 1 , 3 , 5 , 7 to complete the sentence !
When a line is steeper than other one it means it has a greater slope. In this case the slope represents the speed of Melinda and Paul. As shown in the picture, the line that represents Paul's movement has a greater slope than the one that represents Melinda's, it means Paul ran at a faster constant speed than Melinda.
If Melinda ran at a constant velocity of 5mph and Paul ran faster than her, an equation that could represent the relationship between Paul's distance an his time has to have a greater slope than 5, which is 7.

find 5 consecutive odd integers who's sum is -45(solve algebraically)
let the consecutive odd integers be
x, x+ 1, x+ 2, x + 3, x + 4
Average = sum / total number
Average = -45
Total number = 5
-45 = x + x + 1 + x + 2 + x + 3 + x + 4 / 5
Introduce cross multiplication
-45 x 5 = x + x + 1 + x + 2 + x + 3 + x + 4
-225 = x + x + x + x + x + 1 + 3 + 4 + 5
-225 = 5x + 16
Suppose that Kevin's checking account shows a balance of $910.25 at the beginning of the month. During this month, he makes deposits of $175.35, $472.25, $235.40, and $450.15, and he writes checks for $307.50, $289.25, $150.30, and $327.00. Find the end-of-the-month balance in his account.
Answer:
The answer is $1,169.35
Step-by-step explanation:
Deposits is when you put money into your account, so, you'll add what he deposits. which will be $2,242.4, Next when he writes a check it means he took money out of his account so you'll subtract. You'll add up the amount of checks he wrote and subtract your answer with the deposits so, $2,243.4, - $1,074.05 = 1,169.35 and thats how you get your answer.
what is the displacement of a hiker who first walks 1.5 km north, then walked back 0.45 km south, then walks 3.2km north?
Answer:
5.0 km.
Step-by-step explanation:
Answer: 4.25 Km
Step-by-step explanation:
First you're going to consider the first number given as the main one to start with. (1.5 km)
The question told you that the hiker first went north so you can consider north positive, then he walked back south 0.45 km.
So far your calculation should be 1.5 - 0.45 = 1.05
Then the hiker walks again north with a distance of 3.2 km
so now add that to your value (1.05) as 1.5 and 3.2 are going to the same direction and 0.45 is only opposing them
Final calculation: 1.05 + 3.2 = 4.25 (1.5 - 0.45 + 3.2)
Another way of explaination if you didn't get this one:
The two values 1.5 and 3.2 are mentioned to be in the same direction (north), while 0.45 is mentioned to be opposing them going south, so you can either consider it as
(+)1.5 + 3.2 - 0.45 (But this one would make more sense)
Or
- 1.5 - 3.2 + 0.45
Hope you understood and good luck with your studies :D
I was explained this by another tutor but it didn't make too much sense

Now,
For finding the value of the slope, choose two-point from the given table
So,
Suppose the two points are:
[tex](1,\text{ 5) and (}3,\text{ 3)}[/tex]Now,

a = 27°b = 55°c = 55°How to find angles in a parallelogram?A parallelogram is a quadrilateral with opposite sides equal to each other and opposite side parallel to each other.
The diagonal of a parallelogram bisect each other.
Therefore, the angles a, b and c in the parallelogram can be found as follows:
180 - 118 - 35 = a (sum of angles in a triangle)
180 - 153 = a
a = 27 degrees.
Therefore, let's find angle b.
62 + 63 + b = 180 (sum of angles in a triangle)
