In order to solve this question, we need to set up a proportion. We are trying to solve for a percentage, so the proportion will be 22/28 = x/100, where x is the percentage that 22 is out of 28.
22 / 28 = x / 100
2200 = 28x Cross multiply
x = 78.6% Divide
22 is about 78.6% of 28. Remember that, whenever you need a percentage, just set up a proportion like this one.
Hope this helps!
Answer:
The two numbers are 36 and 9
Step-by-step explanation:
Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48
We know that: n <44, 48
Let's try some values:
45 - 40 = 4
45- 36 = 9
45- 28 = 17
45- 24 = 21
Pattern: The lesser a natural numer's absolute value, the greater [larger number] it produces. (Bold = "larger numbers")
We recognize something: 36 + 9 = 45 and 36 is exactly 4 times greater than 9.
Considering the linear function found in part a, we have that:
b) The slope is of AC.
c) The intercept is of AD + B.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
The equation found in part a is:
A(Cx + D) + B.
Placing it in slope-intercept format, we have that it is given by:
ACx + AD + B.
Hence:
b) The slope is of AC, as it is the part that multiplies x.
c) The intercept is of AD + B, as it is the constant term.
