Answer:
k = -3.5
Step-by-step explanation:
6k ÷ 7 = -3
Multiply 7 to both sides
6k = -21
Divide both sides by 6
6k/6 = -21/6
k = -3.5
To check if the answer is correct or not, you can always plug in -3.5 for k in the equation.
6(-3.5) ÷ 7 = -3
-21 ÷ 7 = -3
-3 = -3
-3 equals -3 so it is correct that k = -3.5
The perimeter of a triangle is 60 cm and its sides are in the ratio 3 : 4 : 5. The length of the sides of the triangle are _________
a,10cm, 20cm, 30cm
b,15 cm, 20 cm, 25 cm
c,20 cm, 20 cm, 20 cm
d,15 cm, 35cm, 10cm
Answer:
Hey buddy, here is your answer. Hope it helps u.
Step-by-step explanation:
Let the unknown number be x
Perimeter of triangle= a+b+c
60=3x+4x+5x
60=12x
x= 60/12
X=5 cm
So the first side=3*x
=3*5=15
Second side=4*5=20
Third side=5*5=25
Answer is b
By-Kelyn
[tex] \LARGE{ \underline{ \tt{Required \: answer:}}}[/tex]
Let the sides be 3x, 4x and 5x. Then,
➝ 3x + 4x + 5x = 60 cm
It is because the total sum of the sides i.e. perimeter of the triangle is 60 cm.
➝ 12x = 60 cm
➝ x = 60 cm / 12
➝ x = 5 cm
Hence,
The required length of the sides:
3x = 15 cm4x = 20 cm5x = 25 cmAnd we are done! :D

How would you solve this?
Answer:
3n-6>5
3n>5+6
3n>11
n>11/3
n>3.6
Answer:
n < 1/3
Step-by-step explanation:
-3(n-2) > 5
-3n + 6 > 5
-3n > 5 - 6
-3n > -1
n > -1/-3 (flip the sign of the inequality because you divided by a negative number)
Hence, n < 1/3 OR n < 0.333

Answer:
[tex]n=\frac{386x-75}{5}[/tex]
Step-by-step explanation:
Add like terms
[tex]-35x+3\cdot \frac{3}{5}x-22\cdot \:2x-15=n[/tex]
Add 15 on both sides
[tex]-35x+\frac{9}{5}x-44x-15+15=n+15[/tex]
Simplify
[tex]-35x+\frac{9}{5}x-44x=n+15[/tex]
Multiply sides by 5
[tex]-35x\cdot \:5+\frac{9}{5}x\cdot \:5-44x\cdot \:5=n\cdot \:5+15\cdot \:5[/tex]
Simplify
[tex]-386x=5n+75[/tex]
Divide both sides
[tex]\frac{-386x}{-386}=\frac{5n}{-386}+\frac{75}{-386}[/tex]
You will get
[tex]x=-\frac{5n+75}{386}[/tex]
Then you will solve for n using x
Multiply both sides by 386
[tex]\frac{386\left(5n+75\right)}{386}=386x[/tex]
Simplify
[tex]5n+75=386x[/tex]
Subtraction
[tex]5n+75-75=386x-75[/tex]
Simplify
[tex]5n=386x-75[/tex]
Divide by 5 to get n
[tex]\frac{5n}{5}=\frac{386x}{5}-\frac{75}{5}[/tex]
[tex]n=\frac{386x-75}{5}[/tex]

A city’s population is currently 150,00. If the population doubles every 30 years, what will the population be 60 years from now?
Answer:
60000
Step-by-step explanation:
AFTR 30 YEARS =15000*2=30000
AFTR 60 YEARS=30000*2=60000
First of all, the population is 15,000 NOT 150,00. Do you know why?
After 30 years, 15,000 doubles to become 30,000.
60,000 is twice 30,000.
So, after another 30 years, 30,000 people increases to 60,000.

carol gets paid $10 per hour to work as a lifeguard. This weekend, she worked both saturday and sunday. She made a total of $80. Carol worked for 5 hours on Saturday. For how many hours did she work on Sunday?
Answer:
Carol worked for 3 hours on Sunday
Step-by-step explanation:
If she gets $10 an hour, then she worked 8 hours total.
80 divided by 10.
If carol worked 5 hours on sunday, she worked 3 hours on saturday
8-5 = 3
The addition is one of the four fundamental mathematical operations. The number of hours that Carol works on Sunday is 3 hours.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
Given that Carol gets paid $10 per hour to work as a lifeguard. Also, she made a total of $80. Therefore, the number of hours for which Carol worked is,
Number of hours = $80 / $10 per hour = 8 hours
As it is known that Carol worked 5 hours on Saturday, therefore, the number of hours she worked on Sunday is,
Total number of hours = Number of hours on Saturday + Number of hours on Sunday
8 hours = 5 hours + Number of hours on Sunday
Number of hours on Sunday = 8 hours - 5 hours
Number of hours on Sunday = 3 hours

PLS HELP FOR GEOMETRY

Answer:
22.8
Step-by-step explanation:
The circumcenter is equidistant from all the vertices of the triangle: PV = RV. There are enough dimensions given to let us find RV from the Pythagorean theorem.
RV² = RS² +SV²
RV² = 11² +20² = 521
RV = PV = √521 ≈ 22.8

B. [tex]\frac{\sqrt{3}}{11}, \frac{\pi}{24}, \frac{3}{25}, \frac{9}{100}[/tex]
Step-by-step explanation:
The question is not properly presented. See attachment for proper presentation of question
From the attachment, we have that:
[tex]W = \frac{3}{25}[/tex]
[tex]X = \frac{\sqrt{3}}{11}[/tex]
[tex]Y = \frac{9}{100}[/tex]
[tex]Z = \frac{\pi}{24}[/tex]
Required
Order from greatest to least
First, we need to simplify each of the given expression (in decimals)
[tex]W = \frac{3}{25}[/tex]
[tex]W = 0.12[/tex]
[tex]X = \frac{\sqrt{3}}{11}[/tex]
Take square root of 3
[tex]X = \frac{1.73205080757}{11}[/tex]
[tex]X = 0.15745916432[/tex]
[tex]X = 0.16[/tex] --- approximated
[tex]Y = \frac{9}{100}[/tex]
[tex]Y = 0.09[/tex]
[tex]Z = \frac{\pi}{24}[/tex]
Take π as 3.14
[tex]Z = \frac{3.14}{24}[/tex]
[tex]Z = 0.13083333333[/tex]
[tex]Z = 0.13[/tex] --- approximated
List out the results, we have:
[tex]W = 0.12[/tex] [tex]X = 0.16[/tex] [tex]Y = 0.09[/tex] [tex]Z = 0.13[/tex]
Order from greatest to least, we have:
[tex]X = 0.16[/tex] [tex]Z = 0.13[/tex] [tex]W = 0.12[/tex] [tex]Y = 0.09[/tex]
Hence, the order of arrangement is:
[tex]X = \frac{\sqrt{3}}{11}[/tex] [tex]Z = \frac{\pi}{24}[/tex] [tex]W = \frac{3}{25}[/tex] [tex]Y = \frac{9}{100}[/tex]
i.e.

Nominal ordinal ratio interval (c) the newer system provided information on the distance between exits.
a. True
b. False
Answer:
Following are the answer to this question:
In question, a) ordinal.
In question, b) ratio .
In question, c) true.
Step-by-step explanation:
For its "ordained" existence, regular data is used to conduct surveys and questionnaires. To identify respondents into different categories, a quantitative methodology is employed to sufficient excess.
Its ratio data is defined as a statistical method with the same features as continuous variables, that recognize the proportion of each data to an absolute null as its source. In many other words, the meaning of the line graph may not be positive.
Its newest program gives the gap between exits data.
