An item cost $450 before tax and the sales tax is $13.50. Find the sales tax rate. Write your answer as a percentage.
Answer:
3%
Step-by-step explanation:
If an item cost $450 before tax and the sales tax is $13.50 then the sales tax rate is 3%.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that An item cost $450 before tax
The sales tax of the item is $13.50
We have to find the sales tax rate in percentage
To find the percentage we have to multiply x/100 with four hundred fifty which is equal to thirteen point five
x/100×450=13.5
4.5x=13.5
Divide both sides by 4.5
x=13.5/4.5
x=3%
Hence, if an item cost $450 before tax and the sales tax is $13.50 then the sales tax rate is 3%.

How does the graph of g(x) = −(x + 3)4 compare to the parent function of f(x) = x4?
Answer:
you cant give brainliest you have to earn it
Answer:
The graph will be flipped and move 3 units to the left
Step-by-step explanation:
Parent function: f(x) = x^4
Graph: g(x) = −(x + 3)^4
Compared to the parent function, g(x) will be flipped because of the negative coefficient and move 3 units to the left because of (x+3).

A shirt is regularly priced at 42$. It is on sale for 15% off of the regular price. What is the sale price of the shirt ?
Answer:
$35.7
Step-by-step explanation:
you can convert 15% to a decimal by dividing by 100.
15/100 = .15
if you multiply the decimal by the cost of the shirt you get how much the discount is.
0.15 * $42 = 6.30
so a 15% discount on a $42 shirt is $6.30 off. So you subtract the discount from the total cost.
$42 - $6.30 = $35.70 that is the sale price of the shirt.
Answer:
$35.7

The function q = 230,000 -28p is a demand function which expresses the quantity demanded of a product q as a function of the price charged for the product p, stated in dollars. Determine the restricted Domain and Range of the function.
Answer:
D=[0, 8 214.29]
R=[0, 230 000]
Step-by-step explanation:
In order to find the domain, we must think of the least price you can give to the product you are selling. The price cannot be less than zero, since that would mean that you are giving money to the consumer for taking the product away, so zero is the smallest value p can get.
The greatest value the price can get is the one such that the quantity demanded is zero. So we need to determine that price by setting the equation equal to zero and solving for p.
230,000-28p=0
so we get
-28p=-230,000
[tex]p=\frac{-230,000}{-28}[/tex]
so
p=$8,214.29
so the restricted domain for this function would be:
[tex]0\leq p \leq 8,214.29[/tex]
or in interval notation:
D=[0, 8 214.29]
In order to find the range, we just need to determine what's the least and greatest value the function can get. Since this is a linear function, we can find them by just substituting each of the extreme values of the domain in the function, so we get:
q=230,000-28(0)=230,000
q=230,000-28(8214.29)=0
so the range would be:
[tex]0\leq q \leq 230,000[/tex]
or in interval notation:
R=[0, 230 000]

A video game has the following formula: For every 1,333 in attack power, you gain 3 levels. You get one bonus star per every 38 levels completed. If a player has an attack power of 0.21 million, how many bonus stars could they get? Round to a whole number.
Answer:
Rounded to a whole number, the player has 12 bonus stars.
Step-by-step explanation:
Since the video game establishes that for every 1,333 points of attack power 3 levels are gained, and that the player has a total of 0.21 million attack points, to determine the number of levels that player has it is necessary to perform the following calculation :
0.21 million = 210,000
210,000 / 1,333 x 3 = Levels
472.6 = Levels
Now, every 38 levels, the game awards a bonus star. To determine the amount of bonus stars that the player has, the following division must be made:
472.6 / 38 = X
12.43 = X
Thus, rounded to a whole number, the player has 12 bonus stars.

2. The velocity of an object in motion is given by the function y(t)=-78.4t + 288 where vt is the velocity of the object in meters per second at time t.
B. After how many seconds does the object momentarily come to rest and then change directions?
Answer:
t = 3.7 seconds
Step-by-step explanation:
Linear Modeling
The velocity of an object is modeled by the function
v(t) = -78.4t + 288
Where v is expressed in m/s and t is expressed in seconds.
The velocity is a vector, therefore its sign indicates its direction. If the object is at rest, then its velocity has a magnitude of zero.
To find when the object comes to rest, we set the velocity to 0:
-78.4t + 288 = 0
Now solve for t. Subtracting 288:
-78.4t = -288
Dividing by -78.4:
t = -288 / -78.4
t = 3.7 seconds

Answer: ahhhhhummm I think it’s 5
Step-by-step explanation:
Answer:
(1,6)
Step-by-step explanation:
First you would reflect over y=0. Whenever you reflect over y=0, the y-coordinate will be multiplied by -1, so it changes to (1,-2). (1,-2) is 4 coordinates below the line y=2, so when reflected over y=2, the coordinate will be 4 above y=2, which means that the coordinate will be (1,6)

Jenny bought a pair of pants for $19.99 and two shirts for $7.50. If she gave the cashier 40 dollars how much change did she receive. Assume there are no tax sales
Answer:
Jenny will receive $12.51 in change.
Step-by-step explanation:
We need to find the total cost first.
19.99 + 7.50 = 27.49
We then subtract that from the 40 dollars she gave to get the amount of change she receives.
40.00 - 27.49 = 12.51.
She will receive $12.51 in change.

Jenny will receive $12.51 in change.
We have given that the Jenny bought a pair of pants for $19.99 and two shirts for $7.50.
We need to find the total cost first.
What is the total cost?Total cost=price of pants +price of shirt
19.99 + 7.50 = 27.49
We then subtract that from the 40 dollars
She gave to get the amount of change she receives.
So we have to subtract the total cost from 40 so we get,
40.00 - 27.49 = 12.51.
She will receive $12.51 in change.
