A student was marked tardy five different times in a 40 day period. What percent of the time was the student tardy?
Answer:
12.5%
Step-by-step explanation:
5/40 = .125
.125×100 = 12.5%
The percentage is the indicating hundredth. The percentage of times the students marked will be 12.5%.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
A student was marked tardy five different times in a 40-day period.
Percentage of 5 among 40 →
(5/40) x 100 = 12.5%

Find f(g(x)) and g(f(x)).
Given: f(x)= 3x – 1; g(x) = 7x + 6
Answer:
When f(x)= 3x – 1 and g(x) = 7x + 6,
f(g(x)) = 21x + 17
and
g(f(x)) = 21x - 1
Step-by-step explanation:
Given:
f(x) = 3x - 1
g(x) = 7x + 6
To find f(g(x)), substitute the value of g(x) into f(x).
f(g(x)) = f(7x + 6)
Substitute variable.
f(7x + 6) = 3(7x + 6) - 1
Distribute the 3 inside the parenthesis.
f(7x + 6) = 21x + 18 - 1
Subtract 1 from 18.
f(7x + 6) = 21x + 17
Therefore, f(g(x)) is 21x + 17.
To find g(f(x)), substitute the value of f(x) into g(x).
g(f(x)) = g(3x - 1)
Substitute variable.
g(3x - 1) = 7(3x - 1) + 6
Distribute the 7 inside the parenthesis.
g(3x - 1) = 21x - 7 + 6
Add 6 to -7.
g(3x - 1) = 21x - 1
Therefore, g(f(x)) is 21x - 1.

A local bicycle shop makes $75 on each
Model A bike and $90 on each Model B bike.
The overhead costs for making the bikes are
$1,350. Write an inequality to show how
many of each bike model must be sold so the
company avoids losing money.
The inequality that show how many of each bike model must be sold so the
company avoids losing money is 75x + 90y ≥ $1350
Let x represent the number of model A bikes produced and y represent the number of model B bikes produced.
Since A local bicycle shop makes $75 on each Model A bike and $90 on each Model B bike, hence:
Revenue = 75x + 90y
The overhead cost is $1350, hence to make profit:
Revenue ≥ cost
75x + 90y ≥ $1350
The inequality that show how many of each bike model must be sold so the
company avoids losing money is 75x + 90y ≥ $1350

the measure of an angle is nineteen times the measure of its complementary angle. what is the measure of each angle?
Step-by-step explanation:
officially, complementary angles complete each other to a total sum of 90 degrees.
supplementary angles complete each other to a total sum of 180 degrees.
angle 1 = 19× angle 2
90 = angle 1 + angle 2 = 19×angle 2 + angle 2 = 20×angle 2
angle 2 = 90/20 = 9/2 = 4.5 degrees.
angle 1 = 19×4.5 = 85.5 degrees.
and so, it seems to me, your teachers made a severe definition mistake and aimed for 180 degrees instead of the correct 90 degrees.
in that case, everything doubles.
angle 2 = 9 degrees
angle 1 = 171 degrees
If measure of an angle is 19-times measure of its complementary-angle, then measure of one angle is 85.5° and other is 4.5°.
Let us denote the measure of the angle as = "x" degrees.
The complementary angle is the angle that, when added to the given angle, forms a 90-degree angle.
The complementary-angle to "x" degrees is = (90 - x) degrees,
We know that the measure of the angle is nineteen times the measure of its complementary angle, we can write the equation as :
x = 19(90 - x),
x = 1710 - 19x,
20x = 1710,
x = 1710/20,
x = 85.5,
Therefore, the measure of the angle is 85.5 degrees. The measure of its complementary angle is 90 - 85.5 = 4.5 degrees.

the rectangle with a side of length 12cm has a diagonal of 15cm. what is the perimeter of the rectangle?
Answer: 42 cm
Step-by-step explanation:
First since the second side length is unknow we need to find it.
We will use the Pythagorean theorem which is [tex]a^{2} + b^{2} = c^{2}[/tex]
Since we will be solving for b we will rearrange the equation to be
[tex]b^{2} = a^{2} - c^{2}[/tex]
now to slove input the data we know
[tex]b^{2}[/tex] = 144 - 225
[tex]b^{2}[/tex] = 81
[tex]\sqrt{b^{2} } = \sqrt{81}[/tex]
[tex]b[/tex] = 9
