When using an equivalent fraction to find a percent why do you write 100 as the denominator?
Answers
We do so beacuse it is easy to convert a fraction to a percent when the denominator is 100.
What is equivalent fraction?Equivalent fractions are the fractions that have different numerators and denominators but are equal to the same value.
What is denominator?Denominator is the part of a fraction that is below the line and that functions as the divisor of the numerator.
What is percentage?A percentage or percent is a fraction that always has the denominator as 100.
When using an equivalent fraction to find a percent we write 100 as denominator.
If a fraction does not have a denominator of 100, you can convert it to an equivalent fraction with a denominator of 100, and then write the equivalent fraction as a percent.
We do so because it is easy to convert a fraction to a percent when the denominator is 100.

In ΔOPQ, o = 9.2 cm, p = 2.4 cm and ∠Q=37°. Find the length of q, to the nearest 10th of a centimeter.
Answers
The length of q, to the nearest 10th of a centimeter is 7.6 cm.
Given in question,
In ΔOPQ,
o = 9.2 cm
p = 2.4 cm
∠Q = 37°
Cosine formula ⇒ cos θ = [tex]\frac{o^{2}+p^{2}-q^{2} }{2op}[/tex]
Putting the values in equation,
cos 37 = [tex]\frac{(9.2)^{2}+(2.4)^{2}-q^{2} }{2*9.2*2.4}[/tex]
0.799 = [tex]\frac{84.64 + 5.76-q^{2} }{44.16}[/tex]

By using the concept of compound interest, rate of interest is 3.1 %
What is compound interest?
If the interest on a certain principal at a certain rate over a certain time increase exponentially rather than linearly, the interest earned is called Compound interest.
If the principal is P, rate is r and time is t, then amount is

Given parameters
• Light intensity = 569 lumens
,• Distance = 9
According to the question, Light intensity (I) is proportional to the inverse square of the distance.
This can be expressed mathematically as
Let the intensity of light be represented as I
Let the distance be represented as d

The next thing is to substitute the parameters into the above formula

Given f(x)=3x^3 - 4x^2 + 2x - 1 and g(x) = x - 4, state the quotient and remainder of f(x)/g(x), in the form q(x) + r(x)/g(x)
Answers
Dividing f(x) = 3x³ - 4x² + 2x - 1 by g(x) = x - 4 will yield a quotient of q(x) = 3x² - 8x + 34 and a remainder of 135, that is (3x² - 8x + 34) + 135/(x - 4).
Calculating for the quotient and remainderApplying the long division method will require us to; divide, multiply, subtract, bring down the next number and repeat the process to end at zero or arrive at a remainder.
We shall divide the dividend f(x) = 3x³ - 4x² + 2x - 1 by the divisor g(x) = x - 4 as follows;
3x³ divided by x equals 3x²
x - 4 multiplied by 3x² equals 3x³ - 12x²
subtract 3x³ - 12x² from 3x³ - 4x² + 2x - 1 will result to 8x² + 2x - 1.
8x² divided by x equals 8x
x - 4 multiplied by 8x² equals 8x² - 32x
subtract 8x² - 32x from 8x² + 2x - 1 will result to 34x - 1.
34x divided by x equals 34
x - 4 multiplied by 34 equals 34x - 136
subtract 34x - 136 from 34x - 1. will result to a remainder of 135.
Therefore by the long division method, f(x) = 3x³ - 4x² + 2x - 1 divided by g(x) = x - 4 gives a quotient q(x) = 3x² - 8x + 34 with a remainder of 135.
