Step-by-step explanation:
let the unknown be x
length = x
width = 3.6 cm
Perimeter = 2 lengths + 2 widths
48 cm = x + x + 3.6 + 3.6
48 cm = 2x + 7.2
40.8 = 2x
20.4 cm = x
if you wanna check,
perimeter = 20.4 + 20.4 + 3.6 + 3.6
48 cm = 48
Using the relationship between the dimension of a rectangle and its perimeter, given its perimeter and width, the length is: 20.4 cm.
Recall:
Perimeter of a rectangle (P) = 2(L + W) (relationship between the width, length and perimeter)
Given:
Width (W) = 3.6 cmPerimeter (P) = 48 cmLength (L) = ?Using the relationship between the dimension of a rectangle and its perimeter, the following equation would be derived:
48 = 2(L + 3.6)
Solve for the value of L48 = 2L + 7.2
Subtract 7.2 from each side48 - 7.2 = 2L
40.8 = 2L
Divide both sides by 220.4 = L
L = 20.4 cm
Therefore, using the relationship between the dimension of a rectangle and its perimeter, given its perimeter and width, the length is: 20.4 cm.

Inspectors for a hospital chain with multiple locations randomly select some of their locations for a cleanliness check of their operating rooms. The inspectors check every operating room in the hospitals that were chosen. What sampling method was used?
Answer:
Cluster Random Sample
Step-by-step explanation:
The operating rooms were divided into (hospital locations) and inspectors sampled every operating room from some of the groups.
Sampling method is the method where the subset of an overall population is selected.
The sampling method used was cluster sampling
From the question, we understand that:
The inspectors select some locationsThen all selected locations was checkedThe above illustrates cluster sampling.
This is so because, cluster sampling involves breaking down a population into smaller size.
In this case, the smaller size are the locations that were selected.

When 5 and 6 are multiplied by the same factor, how do the ratios compare to the ratio 5:6?
The ratios are equivalent to 5:6.
The ratios are equivalent to 6:5.
The ratios are greater than 5:6, as the factors become greater.
The ratios are greater than 6:5, as the factors become greater.
Answer:
Aren't they equivalent to 5:6?
Step-by-step explanation:
Your situation models to 5x:6x, and no matter what you put as x, it will amount to the ratio of 5:6. It's basically a big fraction, with 5/6 as the simplfication.
Answer:
Step-by-step explanation:
The easiest way to start this is just to multiply the 5 and the 6 by the same thing and see what happens.
Randomly, I will choose 7 because I think today is the 7th.
5*7
====
6*7
35
===
42
I know this is going to seem ridiculous but I'm not going to divide 35/42 by 7.
35 divide by 7 = 5
42 divide by 7 = 6
Just what you started with.
Now a little less obvious, suppose we multiply top and bottom of the ratio by a. a can be anything like (say) the 5th root of 3233
5* a
====
6 * a
Divide the top and bottom by a.
5a divided by a = 5

6a divided by a = 6

Welcome to the other MHN solving classes.
Let's see what to do ......
_________________________________
Step (1)
EC bisects BED ;
Thus : BEC = CED
_________________________________
Step (2)
Question told us that CED = 4 x + 1
Thus : BEC = CED = 4 x + 1
_________________________________
Step (3)
AD is a straight line which means its angle size is equal to 180° degrees.
So :
AEB + BEC + CED = 180
( 11x - 12 ) + ( 4x + 1 ) + ( 4x + 1 ) = 180
11x + 4x + 4x - 12 + 1 + 1 = 180
19x - 10 = 180
Plus sides 10
19x - 10 + 10 = 180 + 10
19x = 190
Divided sides by 19
[tex] \frac{19}{19}x = \frac{190}{19} \\ [/tex]
[tex]x = 10[/tex]
So : x = 10°
_________________________________
Step (4)
AEB = 11x - 12
AEB = 11(10) - 12
AEB = 110 - 12
AEB = 98°
******************************************************
BEC = CED = 4x + 1
BEC = CED = 4(10) + 1
BEC = CED = 41°

Step (5)
AEC = AEB + BEC
AEC = 98° + 41°
AEC = 139°

reduce [tex]\frac{54}{81}[/tex]
Answer:
[tex]\text{The reduced fraction is } \frac{2}{3}[/tex]
Step-by-step explanation:
Fraction Reduction
To reduce a fraction, we try to divide both the numerator and denominator by the very same number until no more numbers can be found.
The fraction to reduce is:
[tex]\displaystyle \frac{54}{81}[/tex]
Since the denominator is odd, we cannot divide by 2, but we can divide by 3:
[tex]\displaystyle \frac{54}{81}=\frac{18}{27}[/tex]
We divide by 3 again:
[tex]\displaystyle \frac{18}{27}=\frac{6}{9}[/tex]
We divide by 3 one last time:
[tex]\displaystyle \frac{6}{9}=\frac{2}{3}[/tex]
[tex]\text{The reduced fraction is } \frac{2}{3}[/tex]
Elise says, "If you subtract 13 from my number and multiply the difference by -6, the result is -60 ." What is 's number?
please help will give brainiest!
Answer:
n = 23
Step-by-step explanation:
n - 13 x -6 = -60
distribute:
(n x -6) - (13 x -6) = -60
-6n - (-78) = -60
two negatives in front of a number makes it a positive number
so rewrite -6n + 78 = -60
-6n = -60 - 78
-6n = -138
n = [tex]\frac{-138}{-6}[/tex]

At the beginning of the business day, a bank's vault held $575,900. By the end of the day, $(3.5 103) had been added to the vault. How much money did the banks vault hold at the end of the business day write ur answer in standard form
3.5*10^3=3,500
3,500+ 575,900=579,400
The bank vault will hold $575,900 + $3.5 x 10^3 = $579,400 at the end of the business day.
What are integers?An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero.
Now it is given that,
Money in the bank vault at the beginning of the day = $575,900
Money added in the vault at the end of the day = $3.5 x 10^3 = $3,500
Since money is added in the vault thus it is gain.
So, Money added in the vault at the end of the day = + $3,500
Thus, Money at the end of the business day = $575,900 + $3,500 = $579,400
Thus, the bank vault will hold $575,900 + $3.5 x 10^3 = $579,400 at the end of the business day.

In an electrical circuit, the current is related to the power and resistance according to the rule I=pR−−√, where I represents the current (measured in amps), P represents power (measured in watts), and R represents resistance (measured in ohms). What is the electrical power drawn by a device that has a resistance of 15 ohms with a current of 4 amps?
Answer:
[tex]P=0.27\,\,watts[/tex]
Step-by-step explanation:
Consider the formula: [tex]I=PR[/tex]
Here, [tex]I[/tex] represents the current (measured in amps), P represents power (measured in watts), and R represents resistance (measured in ohms).
Resistance = 15 ohms
Current = 4 amps
To find electrical power drawn by a device, put [tex]R=15\,,\,I=4[/tex]
So,
[tex]4=15P\\P=\frac{4}{15}=0.27\,\,watts[/tex]
