The function w(x) = 60x represents the number of words w(x) you can type in x minutes, how many words can you type in 9 minutes
Answer:540 words
Step-by-step explanation:
Given : The function [tex]w(x) = 60x[/tex] represents the number of words w(x) you can type in x minutes.
Then to find the number of words typed in 9 minutes , we need to pit x= 9 in the function .
The number of words can be typed in 9 minutes : [tex]w(9) = 60(9)=540[/tex]
Hence, we can type 540 words in 9 minutes .
deshawn deposited $6500 into a bank account that earned 11.5percent simple interest each year . he earned $4485 in interest befour closing the account. if no money was deposited into or withdrawn from the account, for how many years was the money in the account round the answer to the nearest whole year
The money was in the account for 6 years.
Explanation:To find the number of years the money was in the account, we can use the formula for simple interest: I = P * r * t, where I is the interest earned, P is the principal (initial amount), r is the interest rate, and t is the time in years. We are given that Deshawn earned $4485 in interest and the interest rate is 11.5%. Let's plug in these values and solve for t:
4485 = 6500 * 0.115 * t
Simplifying the equation gives us:
t = 4485 / (6500 * 0.115) ≈ 6.1337
Rounding to the nearest whole year, we can conclude that the money was in the account for 6 years.

a manager purchased a total of 21 coffee mugs and key chains. each coffee mug cost $8.50, and each key chain cost $2.75 . if manager spent total of $132.50, how many coffee mugs did the manager purchase
The manager purchased 13 coffee mugs.
Explanation:To find the number of coffee mugs purchased, we can set up a system of equations. Let's say the number of coffee mugs is represented by x and the number of key chains is represented by y. We have two pieces of information:
1. The total number of items purchased is 21: x + y = 21
2. The total cost of the purchase is $132.50: 8.50x + 2.75y = 132.50
Now we can solve this system of equations to find the value of x, which represents the number of coffee mugs:
Multiplying the first equation by 8.50, we get: 8.50x + 8.50y = 178.50
Subtracting the second equation from this new equation, we get: 8.50x + 8.50y - 8.50x - 2.75y = 178.50 - 132.50
Simplifying, we have: 5.75y = 46
Dividing both sides of the equation by 5.75, we find: y = 8
Substituting this value into the first equation, we can solve for x: x + 8 = 21
x = 13
Therefore, the manager purchased 13 coffee mugs.
A 20,000 gallon swimming pool contains 5000 gallons of water when a hose is placed into the pool and begins adding water at a rate of 1250 gallons per hour. Use the Segment tool to plot a graph representing the volume of water in the pool over time from when the hose is placed into the pool until it is full.
20000-5000=15000
15000/1250=12
it will take 12 hours
Solution: The figure 1 shows the graph of the volume of water in the pool over the time from when the hose is placed into the pool until it is full.
Explanation:
It is given that the capacity of the pool is 20,000 gallon and initial water in the pool is 5000 gallons. The remaining capacity of the pool is 15,000 gallons.
The water in the pool increased at the rate of 1250 gallons per hour.
[tex]\frac{15000}{1250}=12[/tex]
So tank will be full after 12 hours.
The initial water in the pool is 5000 gallons and water in the pool increased at the rate of 1250 gallons per hour. So, the volume of water in the pool is described by the equation [tex]V=5000+1250t[/tex].
First we find the value of volume function in different value of t, then plot these points in a coordinate plane and join them with a straight line.
Hence, the coordinate table and graph of the volume function is given below.

Marc is running 5 kilometers at track practice. He decides to break the run into 3 equal lengths. How long will each length be?
Each length of the track practice will be 1.67 kilometers.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Marc is running 5 kilometers at track practice.
And, He decide to break the run into 3 equal lengths.
Now,
Since, Marc is running 5 kilometers at track practice.
And, He decide to break the run into 3 equal lengths
So, The length of each track practice = 5 / 3
= 1.67 kilometer
Thus, Each length of the track practice will be 1.67 kilometers.

The ordered pairs (1, 16), (2, 25), (3, 36), (4, 49), and (5, 64) represent a function. What is a rule that represents this function?
Also, how do I know how to find the rules of functions?
Answer:
The rule representing the function is [tex]f(x)=(x+3)^2[/tex].
Step-by-step explanation:
We are given,
The ordered pairs for the function are (1, 16), (2, 25), (3, 36), (4, 49), and (5, 64).
It is required to find the rule representing the function.
Now, we see that,
[tex]16=(1+3)^2[/tex]
[tex]25=(2+3)^2[/tex]
[tex]36=(3+3)^2[/tex]
[tex]49=(4+3)^2[/tex]
[tex]64=(5+3)^2[/tex]
From the pattern,we get the function is [tex]f(x)=(x+3)^2[/tex].
Hence, the rule representing the function is [tex]f(x)=(x+3)^2[/tex].

How many students play an instrument? 93 students 130 students 217 students 290 studentsAt Southside Middle School, 30% of the students play an instrument. There are 310 students. How many students play an instrument?
Answer:
93 students
Step-by-step explanation:
We need to calculate the 30% of 310 students.
We can calculate with a direct rule of 3. If the 100% is 310 students, how many students are the 30%?
[tex]100 -\!\!\!-\!\!\!- \text{310 students}\\ 30 -\!\!\!-\!\!\!- \text{x students}[/tex]
We use the formula of the direct rule of 3:
[tex]x = \frac {30 * 310}{100} \\ \\ x = \frac {9,300}{100}\\[/tex]
x = 93
