Ebony wants to leave an 18% tip for a $19.82 restaurant bill. The tax is 6.25%, which is added to the bill before the tip.
Answers
1. find the tax. we are told it is 6.25% in decimal form this is .0625. We need to multiply that by the total 19.82 to find the tax so
[tex]0.0625 \times 19.82 = 1.24[/tex]
so the tax is $1.24
2. Add the tax to the total
[tex]19.82 + 1.24 = 21.06[/tex]
3. calculate a 18% tip. we can do this in our head numerous ways (moving the decimal place to find 10% taking half of that for 5% and moving the decimal again for 1% multiply by 3 and add) but for space we will simply do the same as we did for tax
[tex]21.06 \times .18 = 3.79[/tex]
so our tip is $3.79
4. add the tip to the total
[tex]21.06 + 3.79 = 24 .85[/tex]
so with tax and tip her total is 24.85 However I have found it very common for people to tip just on the price before tax. if this is the case calculate the 18% based just on the original price and add that value plus the 1.24 tax
Ebony will pay a total of $24.85 for her meal after adding a 6.25% tax to the original price of $19.82 and then calculating an 18% tip on the resulting amount, which includes the tax.
The student, Ebony, needs to calculate the total cost of a restaurant bill which involves adding tax and a tip. The cost of her meal is $19.82, with a 6.25% tax to be added before calculating an 18% tip.
First, determine the sales tax amount by converting the percent to a decimal:
0.0625 × $19.82 = $1.24.
Add the sales tax to the meal's original cost to find the total before tip:
$19.82 + $1.24 = $21.06.
Next, calculate the tip amount by converting 18% to a decimal and multiplying by the post-tax total:
0.18 × $21.06 = $3.79.
To find the final amount Ebony will pay including the tax and tip, add the tip to the post-tax total:
$21.06 + $3.79 = $24.85.
Ebony will pay $24.85 at the restaurant's register, using either cash or a credit card, to cover her $19.82 meal with tax and tip.

Question 7 Unsaved A couch cost $825. If the state has a 10% sale's tax. What was the price of the couch before taxes?
Question 7 options:
$785
$750
$735
$700
Answers
The equation can be framed as follows:
Before tax cost *(1+tax rate) = Final cost
Given tax rate = 10% = 0.1
Final cost = $825
Before tax cost *(1+0.1) = 825
Before tax cost * 1.1 = 825
Before tax cost = 825/1.1
Before tax cost = $750
Price of the couch before taxes = $750

how do I solve for x?
Answers
Given: 56 cm of rectangle
Unknown: find x
Length: 2 + x or x + 2
Width: 2x-5
Area = l * w

set x equal to 0
x+2=0 --> x=-2 2x-5=0 --> 2x=5 --> x = 5/2
so the answer we got was x=-2,5/2
we know that x cannot be negative because you can't measure with negative numbers, therefore, 5/2 is your answer
width = b
ab = 56 ---- first equation
a = 2 + x ---- second equation
b = 2x - 5 ---- third equation
substitude second and third equation into the first equation
(2+x)(2x-5) = 56
4x - 10 + 2x^2 - 5x = 56
2x^2 - x - 10 - 56 = 0
2x^2 - x - 66 = 0
(x-6)(2x+11) = 0
x1 = 6 , x2 = - 11/2 ---> - 5.5 (nearest whole num)
William invested $7000 in an account that earns 4.5% interest, compounded annually. The formula for compound interest is A(t) = P(1 + i)t. How much did William have in the account after 3 years? A. $21,340.38 B. $7988.16 C. $7094.93 D. $7945
Answers
Answer:
7988.16
Step-by-step explanation:
This is a matter of plugging in numbers.
P = 7000 (starting value)
l = 0.045 (rate)
t = 3 (number of years)
A(t) = 7000(1 + 0.045)^3
A(t) = 7000(1.045)^3
After three years, William will have 7988.16
The amount in William's account after 3 years with compound interest will be $7,988.16. Hence the correct option is B.
The compounded interest formula is:
A(t) = P(1 + i)^t
where P is the principal amount ($7000), i is the interest rate (4.5% or 0.045), and t is the time in years (3).
Calculate the total amount:
A(3) = 7000(1 + 0.045)^3
A(3) = 7000(1.045)^3
A(3) = 7000 * 1.144976125
A(3) = $7,988.16

(0,0) does not change with the rotation, nor does it change with the dilation.
(2,0) will become (-2,0) with the rotation and (-6,0) with the dilation.
(0,4) goes right around to the - y axis. It become (0,-4) with the rotation. and (0,3*-4) = (0,-12) with the dilation.
There is no way that these triangles are congruent. I could have said that right at the very beginning. But there is a way that they are similar. The angles between them remain unaltered. You can test that out with (0,4) to (0,0) to (2,0) which is a right angle (labeled CAB). No matter what you have done in these two steps, that right angle remains. Dilation other than a dilation of 1 will not produce congruence.

D(No because the wrist circumference of 16 cm is paired with two heights.
Answers
Answer:
Option D(No because the wrist circumference of 16 cm is paired with two heights.
Step-by-step explanation:
In the given graph we have set of points representing the wrist circumferences and heights of six students in Alyssa’s classroom.
x axis represents the wrist circumference while y axis represent the height.
Any relation is called a function if for one value of x we have only one value of y. If the graph passes the vertical line test that is if a vertical line drawn touches the graph at only one point then the graph is called a function.In the given graph for x value x=16 there are two y values 162 and 165.So the graph is not a function.
Among all the options Option D(No because the wrist circumference of 16 cm is paired with two heights.) is the right answer.

you spin a spinner the has 8 equal sized sections numbered. one to eight. Find P( 1 or 2 )
Answers
This wasn't really a complete question but i hope i answered it!!
Fell free to ask questions :)
The probability of spinning a 1 or 2 on a spinner with eight equally sized sections can be calculated using the formula for probability, resulting in a probability of 0.25.
Explanation:The question asks to find the probability of spinning a 1 or 2 on a spinner with eight equally sized sections, each numbered from 1 to 8. The problem is a straightforward application of the concept of probability in mathematics, which can be calculated by the formula P(E) = Number of favourable outcomes / Total number of outcomes.
In this case, the number of favourable outcomes (spinning a 1 or 2) is 2, and the total number of outcomes is the total number of sections on the spinner, which is 8. Therefore, the probability P(1 or 2) is computed as 2 / 8 = 0.25.

Traci plans to conduct a coin-flipping experiment to see if the probability of landing on "heads" or "tails" is close to the theoretical probability of 1 2 . Which experiment is likely to yield a result FARTHEST from the theoretical probability?
Answers
Traci's coin-flipping experiment is more likely to yield results farthest from the theoretical probability of 1/2 if she conducts the experiment with only a few flips, due to the law of large numbers.
Traci wants to investigate the probability of landing on heads using a coin-flipping experiment. To find the result furthest from the theoretical probability, Traci should plan an experiment with fewer flips. The law of large numbers implies that as the number of trials increases, the experimental probability will converge closer to the theoretical probability. Hence, if Traci flips the coin only a few times, there's a greater chance that the experimental results will diverge significantly from the expected outcome of 50% heads and 50% tails. On the other hand, flipping the coin many times, such as in Pearson's experiment with 24,000 flips, is likely to yield a result very close to the theoretical probability. This is because individual variations have less impact on the overall outcome as the sample size increases.

You ran 4 miles. Rob ran half as far as you. Tim ran half as far as rob. Nicole ran half as far as tim. Write an expression for how far Nicole ran
Answers
Final answer:
Nicole ran 0.5 miles. The expression for Nicole's running distance, starting from your 4 miles run, is (4 / 2^3) or 4 / 8, which simplifies to 0.5 miles.
Explanation:
Expression for Nicole's Running Distance
The expression to find out how far Nicole ran is based on a sequence of halving distances starting from the original distance you ran. You ran 4 miles. Rob ran half as far as you, so Rob ran 4 miles / 2 = 2 miles. Tim ran half as far as Rob, therefore Tim ran 2 miles / 2 = 1 mile. Finally, Nicole ran half as far as Tim. Hence, Nicole ran 1 mile / 2, which is equal to 0.5 miles.
In a form of an expression, the distance Nicole ran can be represented as:
(4 / 2) / 2) / 2
Or simplified to:
(4 / 2^3)
Or,
4 / 8 = 0.5 miles
