Lexus skateboards from his house to school 4 miles away. It takes him 20 minutes.
Assume that Lexus skateboards at a constant rate.
Part A
Write an equation to represent the number of miles, m, that Lexus can skateboard in t minutes.
Answer:
[tex]\displaystyle m = \frac{1}{5}\cdot t[/tex]
Step-by-step explanation:
Proportional Model
The number of miles m that Lexus can skateboard in t minutes can be modeled by:
m = kt
It's given that Lexus skateboard from his house to school for a distance of m=4 miles in t=20 minutes.
Substituting:
4 = k.20
Dividing by 20
[tex]k=\frac{4}{20}[/tex]
Simplifying:
[tex]k=\frac{1}{5}[/tex]
This produces the model
[tex]\displaystyle m = \frac{1}{5}\cdot t[/tex]
I used the equation y=4x+20.

A The table shows a proportional relationship.
B. When x is 20, y is 2.55
C. All the ratios y/x for related pairs of x and y are equivalent to 8.
D. The unit rate of y/x for related pairs of x and y is 1/8

How to apply composition between functions
The composition of two functions consists in replacing the variable of the former function ([tex]b(x)[/tex]) by the latter function ([tex]a(x)[/tex]). If we know that [tex]b(x) = \sqrt{x-4}[/tex] and [tex]a(x) = 3\cdot x +1[/tex], then the composite function:
[tex]b\,\circ\,a \,(x) = \sqrt{(3\cdot x+1)-4}[/tex]
[tex]b\,\circ\,a\,(x) = \sqrt{3\cdot x-3}[/tex] (1)
Since the composite function is a square root function, then the domain fulfill the following inequation:
[tex]3\cdot x -3 \ge 0[/tex]
[tex]x \ge 1[/tex]
Hence, the domain of [tex]b\,\circ \,a\,(x)[/tex] is [tex][1, +\infty)[/tex]. [tex]\blacksquare[/tex]

Step-by-step explanation:
The list shows the numbers of each type of pie baked at a bakery today.
• 13 apple
• 4 pecan
• 3 pumpkin
What percentage of the pies baked today were NOT apple?
The percentage of pies baked that were not apple was 33.33 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
The number of apple pies baked at the bakery = 13
The number of pecan pies baked at the bakery = 4
The number of pumpkin pies baked at the bakery = 3
So ,
Total number of pies baked at the bakery =
Number of apple pies baked at the bakery + Number of pecan pies baked at the bakery + Number of pumpkin pies baked at the bakery
Total number of pies baked at the bakery = 13 + 4 + 3
= 21
Now ,
The number of pies that were not apple = Number of pumpkin pies baked at the bakery + Number of pecan pies baked at the bakery
The number of pies that were not apple = 4 + 3
= 7
And ,
The percentage of pies that were not apple =
( The number of pies that were not apple / Total number of pies baked at the bakery ) x 100 %
The percentage of pies that were not apple = ( 7 / 21 ) x 100 %
= ( 1 / 3 ) x 100 %
= 33.33 %
Hence , the percentage of pies that were not apple is 33.33 %

A die is rolled. The set of equally likely outcomes is {1, 2, 3, 4, 5, 6}. Find the probability of getting a 9.
Answer:
you are only rolling 1 dice the probability of getting 9 is 0 there are only 6 sides to one die
Probability of getting a 9 is 0
Give that;
Total number of outcome in die = 6
Total numbers are {1, 2, 3, 4, 5, 6}
Find:
Probability of getting a 9
Computation:
Number of outcome 9 come in a die = 0
So,
[tex]Probability = \frac{Number\ of\ favourable\ outcomes}{Total\ outcomes}[/tex]
Probability of getting a 9 = 0 / 6
Probability of getting a 9 = 0

If two fractions are between 0 and 1, can their product be more than 1? please explain. Thank You.
Answer:
B) always less than either of the original fractions
Step-by-step explanation:
We can easily Answer this by taking some values.
The question states that the two fractions, each have values between 0 and 1.
Let us say one of the fraction is 1/2 and the other fraction is 1/3 .
The product of the two fractions is 1/2 x 1/3 = 1/6 .
is lesser than both 1/2 and 1/3 .
So, the correct answer is that the product is always less than either of the original fractions.
The two fractions are between 0 and 1 their product will always less than either of the original fractions.
What is fraction?A fraction is number expressed "as quotient, in which the numerator is divided by denominator".
According to the question,
If two fractions are between 0 and 1. In order to check their product be more than 1.
Let us assume one fraction is 1/2 and the other fraction is 1/3. The product of the two fractions:
1/2 x 1/3 = 1/6.
Since the value of fraction 1/2 is 0.5, the value of fraction 1/3 is 0.3333 and the value of fraction 1/6 is 0.166667.
It clearly shows 0.5 > 0.16667 and 0.3333 > 0.16667.
Hence, the two fractions are between 0 and 1 their product will always less than either of the original fractions.
