We want to do a change of units of a rate, from words per minute to words per hour.
We will find that the answer is 22,200 words per hour.
The rate that we need to modify is:
370 words/minute
So the time is in the denominator.
Also, remember that:
1 hour = 60 minutes.
Then:
1 minute = (1/60) hours.
Using the above relation, we can replace the "minute" in the denominator by (1/60) hours, so we get:
370 words/minute = 370 words/((1/60) hours.) = 60*370 words/hour
22,200 words/hour.
Then the rate is 22,200 words per hour.

Step-by-step explanation:
A town has accumulated 4 inches of snow and the snow depth is increasing by 3 inches every hour . a nearby town has accumulated 1 inch and the depth is increasing by 5 inches every hour. how many hours will the snowfall of the towns be equal if the snow continues at the given rates?
answer as an equation and solve, please help!!
The equation which represents the given situation as described about snow depths in the task content is; 4 + 3x = 1 + 5x and the solution is; x = 1 and a half hours.
At what time will the snow fall of the towns in discuss have the same snow depth according to the given rates?It follows from the task content that the time at which the snowfall in the towns in discuss will be equal be determined.
According to.the word phrases given;
A town has accumulated 4 inches of snow and the snow depth is increasing by 3 inches every hour. Hence, we have;
4 + 3x.
Also, a nearby town has accumulated 1 inch and the depth is increasing by 5 inches every hour. Hence ,we have;
1 + 5x
Consequently, when the snowfalls are equal, we have;
4 + 3x = 1 + 5x
3 = 2x
x = 3/2.
x = 1 and a half hours.
Ultimately, the equation which represents the given situation as described about snow depths in the task content is; 4 + 3x = 1 + 5x and the solution is; x = 1 and a half hours.

The inequality -15<-6 is given. Perform the given operation, then write a true
inequality to match the result.
Multiply both sides of the inequality by
-1/2
The result of the operation is 30 > 3 and the result is true
How to perform the operation on the inequality expression?The inequality expression is given as:
-15 < -6
The operation on the inequality expression is given as:
Multiply both sides of the inequality by -1/2
So, we start by multiplying both sides of the above inequality by -1/2
This is represented as
-15 * -1/2 < -6 * -1/2
Evaluate the products
So, we have
30 > 3
The above inequality is true because 30 is greater than 3
Hence, the result of the operation is 30 > 3 and the result is true

The total number of tickets bought is 6 and the number of coach tickets bought is 4 while the number of first class tickets bought is 2
How to solve algebra word problems?We are told that a total of 6 people took the trip. If x is the coach tickets and y is the first class tickets and she bought tickets for 6 of them, then we can say that;
x + y = 6 ------(1)
Now, coach tickets cost $270 and first class tickets costs $1250. She used her total budget for airfare for the trip, which was $3580. Thus;
270x + 1250y = 3580 ----(2)
Solving both equations simultaneously gives;

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.

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.

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
