The simplest form of the given expression is c(1+0.065). Therefore, option D is the correct answer.
What is the sales tax?Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.
Given that, Hideki buys a skateboard that costs c dollars.
After 6.5% sales tax is added, the total cost can be expressed by the expression c +0.065c
The simplest form of the expression is
c +0.065c
= c(1+0.065)
= c(1.065)
= 1.065c
The simplest form of the given expression is c(1+0.065). Therefore, option D is the correct answer.

MATH FINAL TOMORROW! PLEASE HELP!
I have no idea what piecewise functions are or how to solve them! Please explain how, thank you!
I'm willing to give up a lot of points to understand this, so please help me.
Answer:
A piece wise function is pretty easy
Think of it like as a lot of functions with inequalities.
So lets say for example
Your Going to a skate park that counts time
Up to 6 minutes costs $50
Over 6 and up to 15 minutes costs $80
Over 15 minutes costs $80 plus $5 per minute above 15 minutes
The function would look something like
H(t)={ $50 If T is less then Or equal to 6
$80 If T is greater then 6 AND T less then or equal to 15
$80+$5(T-15) If T is greater then 15 }
Just simplify the worded problems into inequalities
And then a question would be something like, you visit for 13 minutes, how much would you pay?
It‘d be $80 becuase the chart says, if T (13) is greater then 6 And less then or equal to 15, its be 80 dollars.

Adding which terms to 3x^2y would result in a monomial? Check all that apply
Answer:
[tex]-12x^2y[/tex] and [tex]4x^2y[/tex]
Step-by-step explanation:
Given
[tex]3x^2y[/tex]
Required
What added term would make it a monomial
Options
[tex]3xy[/tex]
[tex]-12x^2y[/tex]
[tex]2x^2y^2[/tex]
[tex]7xy^2[/tex]
[tex]-10x^2[/tex]
[tex]4x^2y[/tex]
[tex]3x^3[/tex]
The given expression, [tex]3x^2y[/tex] has 2 variables; x and y
x has a power of 2 and y has a power of 1.
This implies that, the next term to be added must have y to the power of 1 and x to the power of 2
From the list of given options, only 2 options satisfy this condition.
[tex]-12x^2y[/tex]
[tex]4x^2y[/tex]
When these two terms are added to [tex]3x^2y[/tex], the result is a monomial.
i.e.
[tex]3x^2y - 12x^2y = -9x^2y[/tex]
[tex]3x^2y + 4x^2y = 7x^2y[/tex]

Sergio and Allen ate lunch together in the school cafeteria. Each boy ordered a cheeseburger with fries. Sergio only ate 1/7 of his cheeseburger, while Allen ate 3/7 of his cheeseburger. How much cheeseburger did they eat together?
Answer:
4/7
Step-by-step explanation:
The word together symbolizes that we are adding.
We add the numerators but keep the denominator the same since it is already the same.
1+3 is 4, so that is our new numerator.

Find the input (x) of the function y = 3x - 7 if the output
(y) is 5.
Answer:
The input (x) = 4
Step-by-step explanation:
Since we know what the output (y) is, you can substitute it into the equation to get:
5 = 3x - 7
Then, solve for x, and you’ll get x = 4. The image below shows step-by-step on how to solve for x.

The function g(x) is a transformation of the function f(x) = ? . Which of the following correctly describes g(x)?
9514 1404 393
Answer:
b. g(x) = 0.5f(x)
Step-by-step explanation:
Compared to the line y=x, the graph of g(x) has a vertical scale factor of 1/2. We can also observe that the equation for g(x) is ...
g(x) = 1/2x
If we substitute f(x) for x, then this is ...
g(x) = 1/2f(x) . . . . matches choice B
A biologist wonders if the life span of bats will be affected by two new food sources from invasive species moving into an area. To conduct the experiment, the biologist needs three treatment groups: a group where the diet will not include invasive species (control), a group where the diet will include one invasive species (treatment group 1), and another group where the diet will include the other invasive species (treatment group 2). The biologist chooses the first cloud-free night and catches the first 18 bats that fly out of a cave, placing them into three equal groups of six bats. To decide the treatment for each group, the biologist places three slips of paper labeled control, treatment group 1, and treatment group 2 in a hat and randomly selects 2 slips of paper. The first piece of paper gives the treatment for the first group, the second piece of paper gives the treatment for the second group, and the remaining treatment is given to the third group.
Which component is missing from the biologist’s process?
a.The biologist did not use proper labeling on the pieces of paper.
b.The biologist did not use the appropriate number of treatment groups.
c.The biologist did not randomly assign the individual bats to the treatment groups.
d,The biologist did not randomly choose the weather on the night for bat capture.
Answer:
D
Step-by-step explanation:
Every factor, besides for the factor you are testing for, must be the same for all of the groups and must be randomly selected. Choosing bats from one clear night isn’t random because a cloud free night might effect which bats first fly out of the cave.
It’s like surveying the first few people who walk out of a movie theater and asking if they thought the movie was good. Most likely not because they left so early/quickly. This can skew the results from being completely random and won’t reflect the entire population as a whole accurately.
Also, note that for every other answer choice, they are correct.
A - The biologist did use proper labeling
B - There are enough treatment groups
C - He did randomly assign 6 for each group
Therefore, by process of elimination, it is D.
I hope this helps! :)
The component that is missing from the biologist's process is: c. The biologist did not randomly assign the each of the bats to the treatment groups.
Importance of Random Assignment of Subjects into GroupsWhen carrying out a research study where you have groups created that you want to study, differences between and within groups can be satisfactory ensured that they are not systematic when subjects are randomly assigned to groups.
Thus, it gives the researcher the confidence that groups are the same in terms of variables, and any differences can be confidently ascribed to experimental treatments.
Therefore, the component that is missing from the biologist's process is: c. The biologist did not randomly assign the each of the bats to the treatment groups.Learn more about random assignment on:

Johnny scored 8 out of 10 attempts, Ray scores 1 out of 2 attempts and David scored 12 out of 20 attempts
Which player has the greatest free throw ratio?
Answer:
Johnny
Step-by-step explanation:
If we convert it so everyone has denominators of 20 we get:
(These are still equal to what their scores before were)
Johnny: 16/20
Ray: 10/20
David: 12/20
Johnny has made the most free throw shots, therefore, they have done the best.

Answer:
Johnny has the greatest free throw
Step-by-step explanation:
Lets look at the 1/2 mark of each one
Johnnys half mark is 5/10 he has 8/10 so he’s ahead
Rays half mark is 1/2 he’s at 1/2 so he’s lower then johnny
Davids half mark is 10/20 he’s at 12/20 a little over
Davids= 6/10

What is the distance of the point P(x,y) from y axis? Wht does this even mean?
Answer:
The x value
Step-by-step explanation:
Basically, the question is asking you to find the straight line distance from the y axis to a given point. The y-axis on a coordinate plane is the axis that goes up and down, and the x axis is the one that goes left and right. In a coordinate pair (x,y), x is how far left or right the point is and y is how far up or down it is. so the point (3,9) is three to the right and three up. (See screenshot)
So, the distance that (3,9) would be from the y-axis would be how far right it is, or x, which is 3!

Answer:
it takes 2.56 (or 2 14/25) months
Step-by-step explanation:
Edmond has $45 in his saving account. He wants to purchase a computer that costs $768. He starts to babysit for his cousin and gets paid $90/week. He plans to spend some money and deposit $75/ week in his account. Define a variable and write an equation and solve to find how many months it takes for him to buy the computer. Assume that every month has 4 weeks
Even though Edmond is getting $90 a week, he's only depositing $75
Based on this information your equation would be:
75w = $768 where w = week
To solve that divide 75 by 768
w = 10.24 or 10 6/25
If there are 4 weeks in a month then your new equation would be
w/4 = m where m = months
To solve this, substitute w for 10.24 or 10 6/25
(10.24)/4 = m
m = 2.56 or 2 14/25
Find the value for x for which r ll s. Then find m<1 and m<2. m<1 = (60-2x)to the zero power m<2 = (71 - 3x)to the zero power. The value for x for which r || s is ?
