-3+|n-2|>5
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
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.
A car wheel has a diameter of 20.8 inches.
About how far does the car wheel travel in 1 rotation? 5 rotation? 30 rotations?
Answer:
65.312 inches326.56 inches1959.36 inchesStep-by-step explanation:
Givend = 20.8 inchesTo findTravel in 1, 5, 30 rotationsSolutionCircumference of the wheel is equal to one full rotation
C = πd = 3.14*20.8 = 65.312 inches5C = 5*65.312 = 326.56 inches30C = 30*65.312 = 1959.36 inchesAnswer:
1 rotation: 65.312 inches
5 rotations: 326.56 inches
30 rotations: 1959.36 inches
Circumference = π and diameter
3.14 x 20.8 = 65.312 inches
5C = 5 x 65.312 = 326.56 inches
30C = 30 x 65.312 = 1959.36 inches

Answer:
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.

Round to the nearest tenth, if necessary.
PLS HELP FOR GEOMETRY
9514 1404 393
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

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]
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

Exits along interstate highways were formerly numbered successively from the western or southern edge of a state. However, the department of transportation has recently changed most of them to agree with the numbers on the mile markers along the highway. (a) what level of measurement were data on the consecutive exit numbers? Nominal ratio interval ordinal (b) what level of measurement are data on the milepost numbers? 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.
