Answer:
Girls = 16
Total students = 40
Step-by-step explanation:
40% of the students are girls, this means 60% of the students are boys.
To find the number of girls, setup a proportion using the percentages and actual number of students in the class. I am going to make the numerator the numbers that go with the girls and the denominator will be the numbers that go with the boys.
Also let's convert the percentages to decimals by moving the decimal two places left.
40% = 0.4 and 60% = 0.6
Now let's find the total number of students by adding the number of girls to the number of boys.
16 + 24 = 40
Answer:
48 ways
Step-by-step explanation:
Let me take a guess
S₁_₁₅ = (1+15)*7 + 8 = 120
There are 48 combinations of distinct digits from 1 to 15 to make 20
120-20=100
So every 20 has a corresponding 100
I wish I got it right, otherwise report it.

Using proportions, it is found that the federal tax rate is of 10%.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The tax rate is the <u>proportion that $17.50 is of $175</u>, hence:
r = 17.50/175 = 0.1 = 10%.
The federal tax rate is of 10%.

The sequences of transformations that could be applied to the parent function will be:
- reflect over the y-axis, vertically stretch by a factor of 3, and then shift down 1 unit
- shift right 1 unit, reflect over the y-axis, and then vertically stretch by a factor of 3.
- reflect over the x-axis, vertically stretch by a factor of 3, and then shift down 1 unit.
<h3>What is transformation?</h3>
A transformation of a function is a function that turns one function or graph into another, usually related function or graph.
In this case, the sequences of transformations could be applied to the parent function f(x) = x to obtain the graph of g.
