Answer: 42
Step-by-step explanation:
Answer:
A class of 60 children
3/10 were absent
So we’re trying to find how many pupils are here (kids).
So lets use percentage.
Percentage means out of a hundred so 3/10 is 30/100.
Multiply 10 on each numerator/denominator and you’ll get 30/100.
Now 30/100 is 30 percent.
We are to find 30 percent of 60.
18 pupils are absent.
We’re trying to find who’s here so
60 - 18 = 42
42 pupils are present

if RST is an equilateral triangle, find x and the measure of each side.
S 12x - 22 R 10x - 6 T 7x + 18
O X=8
O X=6
O X=4
O X=2
Answer:
x = 8
Step-by-step explanation:
In equilateral, the length of the sides are equal.
12x - 22 = 10x - 6
Add 22 to both the sides
12x = 10x - 6 + 22
12x = 10x + 16
Subtract '10x' from both sides,
12x -10x = 16
2x = 16
Divide both sides by 2
x = 16/2
x = 8
Which of the following functions has an initial value of 0 and a rate of change of 3?
The following function has an initial value of 0 and a rate of change of 3 will be y = 3x and it is shown in option (D) hence option (D) will be the correct answer.
How to graph a function?Drawing the graph of the appropriate function is the process of graphing a function.
Graphing simple functions like linear, quadratic, etc. is fairly easy, complex functions like rational, exponential, etc. require some skill and comprehension of certain mathematical thinking.
In other words graph of a function is a grammatical representation in the coordinate geometry.
Given that the function has a rate of change as 3
We know the rate of change is nothing but derivative so
dy\dx = 3
dy = 3dx
by integration
y = 3x + c now given that the initial value is zero so by putting x and y as 0.
c = 0
So the function is y = 3x so it is That the option (D) has the same behavior.

What is X? its just lines,
Answer:
x= 8
Step-by-step explanation:
Angles ∠LPJ and ∠MPK are equal to each other
So ∠LPJ = [tex](3x+12)[/tex]
We can add angles ∠LPJ and angle ∠JPQ for a total of 90 degrees
Now with the below equation set up, you can solve for X.

As Program Director of a Radio Station, you receive a report from an independent service that shows that out of 100 songs played, the same song was played 7 times. Using the Empirical Approach, calculate the probability that song will be played next.
Using an Empirical approach and the probability concept, it is found that there is a 7% probability that song will be played next.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes. Using an Empirical approach, these number of outcomes are taken from previous trials.
In this problem, considering the previous 100 songs, the same song was played 7 times, hence:
p = 7/100 = 0.07.

Answer:
-1 2/3 - (-1/3) = -4/3
Step-by-step explanation:
the first thing to note is that when you subtract a negative it is essentially adding
so your question is essential asking
write a statement involving one negative number or fraction added to another number or fraction
but you must write it like this
a - (-b) = -4/3
-5/3 - (-1/3) is essentially just -5/3 + 1/3
you can also write -5/3 as -1 2/3
this gives you -4/3

Peter is the owner of a hotel. He has found that when he charges the nightly cost of $139, the average occupancy is 275. In addition, Peter has found that with every $10 increase in the average nightly cost, the hotel occupancy decreases by an average of 22.
Which of the following functions describes the hotel's profit in terms of x, the number of $10 increases over $139?
Answer:
Without price increase, Cost/night = $119
Average occupancy = 372 The revenue will be 119*372 = $44,268
For every $15 price increase, the occupancy decreases by 25. Therefore with x price increases, The revenue will be $(119 + 15x)*(372 25x)
Cost/night = $119 + 15x Occupancy = 372 - 25x
Answer:
The nightly cost with x $15 price increases is $119 + 15x.

here a subtraction problem that has been solved incorrectly for 44-16=28 choose the addition sentence that check this subtraction problem the choices are 28+16=32 28+44=72 28+16=44 which one is correct
Answer:
Answer:
28+16=44
Step-by-step explanation:
point of correction it has been solved correctly
when subtracting 44 - 16 it gives you 28
=> 44 - 16
=> 28
SO IN ORDER TO CHECK IF THE PROBLEM WAS SOLVE CORRECTLY
you will minus 28 from one of the numbers before the equal sign
the correct option is 28 + 16 equals to 44
=> 28+16=44
An instructor wants to create a test that has true-false questions, multiple-choice questions,
and essay questions. He wants the test to have 35 questions, with twice as many multiple-choice
questions as essay questions and with twice as many true-false questions as multiple-choice
questions.
(i). Write a system of equations to represent this problem.
(ii). Hence or otherwise, determine how many of each type of question should the
instructor put on the test?
Let x = multiple choice, y = true/false, z = essay
(i)
where: x + y + z = 35
We need to solve for y first, in order to know how many essay questions there are, since that is our base.
y + 2y + 4y = 35
(ii)
Now to solve:
y + 2y + 4y = 35
7y = 35
[tex]\frac{7y}{y} = \frac{35}{7}[/tex]
y = 5
Therefore, there are 5 essay questions, 10 multiple choice questions, and 20 true/false questions.
10 + 5 + 20 = 35
The equation of the system will be x + y + z = 35 and the number of each type of question should the instructor put on the test will be 5.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
An instructor wants to create a test that has true-false questions, multiple-choice questions, and essay questions.
Let x be the number of essay questions.
Let y be the number of multiple-choice questions.
Let z be the number of true-false questions.
He wants the test to have 35 questions, with twice as many multiple-choice questions as essay questions and with twice as many true-false questions as multiple-choice questions.
x = 2y
z = 4y
1. Then the equation of the system will be
x + y + z = 35
Then we have
2. Then the number of each type of question should the instructor put on the test will be
y + 2y + 4y = 35
y = 5
