At Southside Middle School, 30% of the students play an instrument. There are 310 students. 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

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].

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.

which is a solution of the inequality y < x - 8
A solution to the inequality 'y < x - 8' is any point where the y-value is less than the x-value minus 8. An example solution is the point (10, 1). To find all solutions, one would graph the boundary line y = x - 8 and shade the region below it, without including the line itself.
Explanation:The question 'which is a solution of the inequality y < x - 8' falls within the subject of Mathematics, specifically under the topic of inequalities in algebra. A solution to this inequality is any ordered pair (x, y) where the y-value is less than the x-value minus 8. For example, if x is 10, then y must be less than 2 to satisfy the inequality, such as the point (10, 1).
To visualize this, you would graph the line y = x - 8 and then shade the region below this line on a coordinate plane. The shaded region represents all the points where the y-coordinate is less than the x-coordinate minus 8, thus showing all the potential solutions to the inequality. Points on the boundary line are not included since the inequality is strictly less than, not less than or equal to.
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.
