Explanation:
12 = 3*4
15 = 3*5
The GCF of 12 and 15 is 3
LCM of x and y = (x*y)/(GCF of x and y)
LCM of 12 and 15 = (12*15)/(GCF of 12 and 15)
LCM of 12 and 15 = (12*15)/(3)
LCM of 12 and 15 = 60
-------------------
We can confirm this by listing out the multiples of each
multiples of 12 are: 12, 24, 36, 48, 60, 72, ...
multiples of 15 are: 15, 30, 45, 60, 75, ...
-------------------
Since the LCM is 60, this means their schedules line up every 60 minutes, aka 1 hour.
If they arrive together at 9 AM, then their next arrival time together is 10 AM which is the final answer.
Mason is going to an amusement park. The prize of the admission into the park is $30, and once he is inside the park, he will have to pay $2 for every ride he rides on. How much money would mason have to pay in total if he goes on 9 rides? How much would he have to pay if he goes on r rides
Answer: $48 for 9 rides
$(30+2r) for r rides
Step-by-step explanation:
r=rides. t=total money spent
t=30+2r
t=30+2(9)
t=30+18
t=$48 for 9 rides
t=$(30+2r) for r rides
Mason has to pay $48 as total if he goes on 9 rides and he would have to pay a total of $30 + $2r if goes on r rides.
If Mason goes on 9 rides, we can calculate his total cost using the given information.
Admission cost: $30
Cost per ride: $2
Number of rides: 9
Total cost = Admission cost + (Number of rides × Cost per ride)
Total cost = $30 + (9 × $2)
Total cost = $30 + $18
Total cost = $48
Now, let's calculate how much he would have to pay if he goes on "r" rides.
Total cost = Admission cost + (Number of rides × Cost per ride)
Total cost = $30 + (r × $2)
Total cost = $30 + $2r
So, if Mason goes on 9 rides, he would have to pay a total of $48 and if Mason goes on "r" rides, he would have to pay a total of $30 + $2r.

What is the value of x in the equation 1/5x - 2/3y = 30, when y = 15?

8
80
200
Answer:
x = 200
Step-by-step explanation:
substitute y = 15 into the equation
[tex]\frac{1}{5}[/tex] x - ([tex]\frac{2}{3}[/tex] × 15) = 30
[tex]\frac{1}{5}[/tex] x - (2 × 5) = 30
[tex]\frac{1}{5}[/tex] x - 10 = 30 ( add 10 to both sides )
[tex]\frac{1}{5}[/tex] x = 40 ( multiply both sides by 5 to clear the fraction )
x = 5 × 40 = 200

researchers are concerned that the weight of the average american school child is increasing implying, among other things, that children's clothing should be manufactured and marketed in larger sizes. if x is the weight of school children sampled in a nationwide study without rounding, what is x an example of?
X in an example of stochastic variable.
What is meant by stochastic variables?
Typically, a random (or stochastic) variable is defined as a variable that can assume more than one value due to chance.
The correct answers are: (a) stochastic variable: By stochastic variable we mean a variable (here X: the weight of students) whose values are subject to variation due to chance.
Here since X is the weight of the children sampled, hence X will vary along with change in the sampling units which gets selected by chance.
Hence X for a sample A and X value for a different sample B will be different. So the values of X vary due to chance ( chance takes part in the selecton of the sample). So X is a stochastic variable.

Renting from Company B will be cheaper if Samir drives the truck 100 miles. Then the correct option is D.
What is a linear equation?
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Let y be the total amount and x be the number of miles.
Samir can rent a moving truck from Company A for $35 plus $0.50 per mile. Then the equation will be
y = 0.5x + 35 ....1
Company B for $25 plus $0.70 per mile. then the equation will be
y = 0.7x + 25 ....2
For the same rent, the number of miles will be
0.7x + 25 = 0.5x + 35
0.2x = 10

a company's charge for electricity is ¢6.434 per kilowatt-hour. in addition, each monthly bill contains a customer charge of $7.81. if last year's bills ranged from a low of $51.74 to a high of $192.28, over what range did usage vary (in kilowatt-hours)? course hero
The range in which the usage vary is from 682.77 kilowatt-hours to 2867.11 kilowatt-hours.
Given the charge of electricity charge is 6.434 cents per kilowatt-hour.
Fixed customer charge = $7.81
Bill range = $51.74 to $192.28
Since every value is in $ , we will first convert cents to dollar
per kilowatt-hour charge will be $6.434/100 ( as $1 = 100 cents )
per kilowatt-hour charge = $ 0.06434 …(1)
Lets us first find the lower range of usage
Last year's lowest bill was $51.74 (including the customer charge)
So last year lowest bill = $51.74-$7.81 = $43.93 …(2)
We know that (per KWh charge)x(no. of KWh used)=Total bill. …(3)
Substituting the values from (1) & (2) we get
(0.06434)x(no. of KWh used)=$43.93
no. of KWh used=[tex]\frac{43.93}{0.06434} = 682.77 KWh[/tex]
Similarly we will solve for maximum KWh used
Lets us find the maximum range of usage
Last year's highest bill was $192.28 (including the customer charge)
So last year highest bill = $192.28-$7.81 = $184.47 …(4)
Substituting the value of (1) & (4) in (3) we get
(0.06434)x(no. of KWh used)=$184.47
no. of KWh used=[tex]\frac{184.47}{0.06434} =2867.11 KWh[/tex]
Therefore , the The range in which the usage vary is from 682.77 kilowatt-hours to 2867.11 kilowatt-hours.

Root 40 to the nearest 10
Root 40 to the nearest 10 is 6.3
The root of a number in math is a number that when multiplied by itself produces the original number. For example, the square root of 49 is 7 because 7×7=49.
Rounding off to the nearest 10 means that we wish to round off the last two digits of a number, that is up to the tens place of a number.
We have been given that 40 is the number whose root we have to round off so here are step-by-step instructions for how to get the square root of 40 to the nearest tenth:
Step 1: Calculate. We calculate the square root of 40 to be: √40 = 6.32455532033676.
Step 2: Reduce. 6.32.
Step 3: Round. Round 6.32 so you only have one digit after the decimal point to get the answer: 6.3.
So therefore the nearest 10 of root 40 is 6.3
