You purchase 9.25 gallons of gasoline at $3.15/gallon. You also buy gum ($1.10) and
windshield wiper fluid ($4.97). The state has a food tax of 4% and you give the clerk $30.00
cash. You pay the rest with your debit card. How much is charged to your debit card?
Answer:
$ 5.25 is charged to debit cardStep-by-step explanation:
Add 4% food tax:
1.1*1.04 = 1.14 (rounded)Total amount of purchase is:
9.25*3.15 + 1.14 + 4.97 = 35.25Subtract $30 paid in cash:
35.25 - 30 = 5.25Answer:
$5.25
Step-by-step explanation:
Cost of gasoline
9.25 gallons at $3.15 per gallon:⇒ 9.25 × $3.15 = $29.1375
Cost of gum
$1.10 plus 4% food tax:
⇒ $1.10 × 1.04 = $1.144
Total cost of purchases
Gasoline + gum + Windshield wiper fluid
⇒ $29.1375 + $1.144 + $4.97 = $35.2515 = $35.25 (nearest cent)
If $30.00 was paid by cash and the rest was paid for by debit card:
Debit card charge = $35.25 - $30.00 = $5.25

It should be noted that mathematical transformations involve changing an image in some prescribed manner.
What is a transformation?Your information is incomplete. An overview will be given. A transformation is a general term for the specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.
It should be noted that the original shape of the object is called the pre-Image and the final shape and position of the object is the image under the transformation.
There are four main types of transformations: translation, rotation, reflection and dilation. Also, in geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other

the graph of f(x) can be stretched vertically and flipped over the x-axis to produce the graph of g(x). if f(x)
The correct option is D: G(x) = -5x².
The equation of G(x) will be -5x² after vertically stretching and flipping.
What is meant by stretching vertically and flipping?A function change called a stretch or compression makes a graph bigger or narrower without moving it horizontally or vertically.
Vertical stretching: A function's graph is stretched or compressed vertically in proportion to the graph of the original function when we multiply it by a positive constant. We obtain a vertical stretch if the constant is bigger than 1, and a vertical compression if the constant is between 0 and 1.flipped over the x-axis: In order to reflect over the X axis, one must negate the value of each point's y-coordinate while maintaining its x-value. The graph reflects across the x-axis prior to transformation when the parent function f(x) = x² has an a-value smaller than 0. The function f(x) = -x² is the result.To know more about the vertical stretch, here

an economic research commission claimed that among the 500 stores there are 308 dealing with european companies, 266 dealing with asian companies 103 dealing with both sides regularly and 59 not dealing with either side. i) what is the probability that the stores deal with european or asian companies? ii) what is the probability that the stores do not deal with european companies? iii) what is the probability that the stores only deal with asian companies? iv) what is the probability that stores do not deal with only one type of company
Step-by-step explanation:
Let S be the set of all the stores in the sample, A be the set of stores dealing with Asian companies and E but the set of stores dealing with European companies
i. The set of stores that deal with European or Asian companies is A ∪ E. The inclusion-exclusion principle states that |A ∪ E| = |A| + |E| - |A ∩ E| = 266 + 308 - 103 = 471. So P(A ∪ E) = 471/500 = 0.942
ii. E' = S - E. |S-E| = 500 - 308 = 192. So P(E') = 192/500 = 0.384
iii. |A - E| = |A| - |A ∩ E| = 266 - 103 = 163. So P(A - E) = 163/500 = 0.326
iv. Stores that do not deal with only one type of company, must deal with both Asian and European companies. We are given that |A ∩ E| = 103. So P(A ∩ E) = 103/500 = 0.206

The function f(x) = 200(0.5)x/50 models the amount in pounds of a particular
radioactive material stored in a concrete vault, where x is the number of years since
the material was put into the vault. Find the amount of radioactive material in the
vault after 140 years. Round to the nearest whole number.
Answer:
29 years
Step-by-step explanation:
Given the function [tex]f(x)= 200(0.5)^{\frac{x}{50} }[/tex], where x stands for the number of years since the material was put into the vault, we can plug 140 into x to find the amount leftover.Another way of doing this is to change the function to [tex]f(x)=200(0.5^{\frac{1}{50} })^{x}[/tex] which are equivalent functions, and then plug 140 into x. This function is helpful if you also needed to find the rate. I'll use the 1st function because the question doesn't ask for the rate[tex]f(x)= 200(0.5)^\frac{140}{50}}[/tex]

Dina's mother is four times older than Dina. Dina is 35 years younger than her father. Dina's father was 5 years older than Dina's mother when Dina was born. How old is Dina now?
Answer:
10 years old
Step-by-step explanation:
Let m = mother's age
Let f = father's age
Let d = Dina's age
m = 4d d = f-35 f = m+5
Substitute the middle equation in to the first equation
m = 4(f - 35) Use the distributive property
m = 4f - 140 subtract 4f from both sides
*m -4f = -140
In equation 3 above, subtract m from both sides to get
f = m+5
f - m = 5 rearrange so that the m term is first
*-m + f = 5
Now add the equations together that have *
m -4f = -140
-m + f = 5
-3f = -135 Divide both sides by -3
f = 45 This is the father's age. To find Dina's age, plug 45 into the second equation above:
d = f -35
d = 45 -35
d = 10.
To find the mom's age, use the third equation:
f = m+5
45 = m + 5
40 = m
You can check this by plugging the answers you found and you can see that all three equations are solved.
m = 4d d = f - 35 f = m + 5
40 = 4(10) 10 = 45 - 35 45 = 40 + 5
40 = 40 10 = 10 45 = 45
A designer is hanging a mirror that is 101 centimeters (cm) wide in a room.
The center of the wall is 190 cm from the right end of the wall. If the designer
hangs the mirror so that the center of the poster is located at the center of the wall,
how far will the left and right edges of the poster be from the right end of the wall?
Answer:
240.5 cm and 139.5 cm, respectively
Step-by-step explanation:
101 cm / 2 = 50.5 cm
The right edge of the mirror is 50.5 cm to the right of the center line.
The right end of the wall is 190 cm from the center line.
190 cm - 50.5 cm = 139.5 cm
139.5 cm + 101 cm = 240.5 cm
240.5 cm and 139.5 cm, respectively

The answers are as follows:
a. There are 6 ways of tossing a coin and then drawing a marble from the bag. (Tree diagram is shown in the diagram below) The probability is 1/12.
b. These are independent events since tossing a coin does not affect the drawing of marble from the bag.
c. From the tree diagram, the probability of tossing a head and drawing a red marble is 1/6(since they are independent events).
d. The probability of drawing two blue marbles if the first marble is not replaced is 1/5(since they are dependent events).
What are compound events in probability?Two or more events that occur simultaneously or one after the other are said to be compound events. They are calculated by multiplying the probability of the first event by the probability of the second event.Calculation:It is given that a bag contains,
Number of white marbles(W) = 1
Number of Blue marbles (B) = 3
Number of Red marbles (R) = 2
Thus, there are 6 marbles in the bag. So, the sample space for drawing a marble = 6
a. Finding all the possible outcomes using a tree diagram:
The possible outcomes from the tree diagram are
(H, W), (H, B), (H, R), (T, W), (T, B), and (T, R)
The probability of tossing head or tail = 1/2
The probability of drawing a marble from the bag = 1/6
So, the compound probability = (1/2)(1/6) = (1/12)
The sample space for this is 12.
b. Independent or dependent events:
These are independent events since the tossing of a coin does not affect the drawing of marble from the bag.
c. Finding the probability of tossing a head and drawing a red marble:
The probability of tossing a head = 1/2
The probability of drawing a red marble = 2/6 = 1/2
Since they are independent events,
The required probability = (1/2)(1/2) = 1/4
d. Finding the probability of drawing two blue marbles if the first marble is not replaced:
The probability of drawing a blue marble from the bag(1st attempt) = 3/6
The probability of drawing another blue marble from the bag (2nd attempt) = 2/5 (From the leftover marbles after the first attempt)
Since they are dependent events, the probability of the 2nd event is calculated only after the first event is calculated.

Now, notice that w e can rewrite the above expressions as:
a*b = x*x
This means that x would be the side-length of a square that has the same area as a rectangle with width b and length a.
Now, if you know the values of a and b (you can get these by using a ruler for example)
Then you can replace them in the equation:
a*b = x*x
√(a*b) = x
And find the value of x that meets the given condition.
