Answer:
So if you wanna calculate the tip of something, you take your total price. You take percentage of tax and make it 0.15. Then, multiply it by your total price and add that to the bill. So basically I'm sorry but I can't think of an equation...
The formula for calculating the sales tax on a good or service is: selling price x sales tax rate, and when calculating the total cost of a purchase, the formula is: total sale amount = selling price + sales tax.

Colin is painting figurines. He spends 20 minutes painting each figurine. After painting for 60 minutes, he still has 9 more figurines left to paint.
The number f of figurines left to paint is a function of t, the amount of time in minutes Colin spends painting.
f=________
Answer: f=180, because you multiply 9 and 20 to find out how many minutes it takes

In a gift store, the ratio of cards to flowers was 8 to 7. If there were 56 cards, how many flowers were there?
Answer: 49 flowers
Step-by-step explanation:
Solve for x by cross-multiplying.
8/7 = 56/x
8x = (7)(56)
8x = 392
x = 49

Suppose that x and y vary inversely, and x = 12 when y = 8. Write the function that
models the inverse variation.
Oy = 96
Oy = 20
y = 0.67x
y =4/x
The function that models the inverse variation is y=96/x. Thus, the correct option is A.
What is the directly proportional and inversely proportional relationship?Let there are two variables p and q
Then, p and q are said to be directly proportional to each other if
p = kq
where k is some constant number called the constant of proportionality.
This directly proportional relationship between p and q is written as
p∝q where that middle sign is the sign of proportionality.
In a directly proportional relationship, increasing one variable will increase another.
Now let m and n be two variables.
Then m and n are said to be inversely proportional to each other if
\(m = \dfrac{c}{n} \\\\ \text{or} \\\\ n = \dfrac{c}{m}\)
(both are equal)
where c is a constant number called the constant of proportionality.
This inversely proportional relationship is denoted by
\(m \propto \dfrac{1}{n} \\\\ \text{or} \\\\n \propto \dfrac{1}{m}\)
As visible, increasing one variable will decrease the other variable if both are inversely proportional.
Given that x and y vary inversely. Therefore, the relation can be written as,
y ∝ 1/x
y = k × 1/x
y = k/x
Also, when y =8, the value of x is 12, therefore, if we substitute the points in the above-formed equation,
y = k/x
8 = k /12
k = 96
Hence, the function that models the inverse variation is y=96/x. Thus, the correct option is A.

You have used the Distributive Property to transform numerical expressions such as (5)(3) + (2)(3) to (5 + 2)(3). How would you transform 5x + 2x into a single term? Substitute five different values into the expressions 5x + 2x and 7x - 1. What do you notice about the values of the expressions? Is there any value that would make the two expressions equal? Why or why not? No Response(s) Be the first to respond to the Discussion topic!
This is 100 pts
Answer:
see below
Step-by-step explanation:
we take out a common term (factor) from the expressions /numbers which are being added . In the given expression 5x + 2x , the common factor is x , so we can write it as x(5+2) .
Now we can add 5 and 2 inside the brackets that would be 7 , so in single term it would be 7(x) = 7x .
Substituting 5 different values
In 5x + 2x1. put x = 0 , 5*0 +2*0 = 0 + 0 = 0
2. put x = 1 , 5*1+2*1 =5+2 = 7
3. put x = 2 , 5*2+2*2 = 10+4 = 14
4. put x =3 , 5*3+ 2*3 = 15+6 = 21
5. put x=4 , 5*4+2*4 = 20+8 = 28
In 7x -11. put x = 0 , 7*0 -1 = -1
2. put x = 1 , 7*1-1 = 6
3. put x = 2 , 7*2 -1 = 13
4. put x =3 , 7*3-1 = 20
5. put x=4 , 7*4 -1 = 27
For any value that makes them equal ,
equate the given equations ,
5x + 2x = 7x -1
7x = 7x -1
7x -7x = -1
0 = -1
thus we arrived at a contradiction, so there won't be any values for which the equations will be equal. Also we notice that for same values the result of 2nd equation is one less than equation 1.
And we are done!

At 78°F, a certain insect chirps at a rate of 106 times per minute, and at 81°F, they chirp 112 times per minute. Write an equation in slope-intercept form that represents the situation.
Answer:
y=2x-50
Step-by-step explanation:
\(m=\frac{y^2-y^1}{x^2-x^1} = \frac{112-106}{81-78} =\frac{6}{3} =2\)
slope-intercept formula(substitute 81 for x, 112 for y, and 2 for m:
y=mx+b
112=2(81)+b
112=162+b
Then subtract 162 from both sides, and b=-50
Plug in all numbers into original equation
y=mx+b m=2 b= -50
So u get y=2x-50

Answer:
\(\frac{16}{27}\)
Step-by-step explanation:
From the table, we notice that the total number of students is:
\(3+10+8+6=27\)
Then, along the second column of the table, we notice that the number of students who do not have a brother is:
\(10+6=16\)
So, the probability that a randomly chosen student does not have a brother is:
\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)
