Zoe goes out to lunch. The bill
, before tax and tip, was $11.70.
A sales tax of 9% was added on. Zoe tipped 13% on the
amount after the sales tax was added. How much was the
sales tax? Round to the nearest cent.
Answer:
$60
Step-by-step explanation:
To find how much Zoe paid before the sales tax and tip, we first need to consider the amount she paid in sales tax and tips.
Sales tax + Tips = $18.60
Let x = original price
Sales tax = 11% * original price
Sales tax = 0.11 * x
x= 0.11x
Tips = 20% * original price
Tips = 0.20 * x
x = 0.2x
Now that we have a value for both the sales tax and tips, we can then proceed to find the original price by:
0.11x + 0.2x = 18.60
0.31x = 18.60
Now we need to divide both sides by 0.31 to find x.
x = 60
Zoe's dinner before the sales tax and tips was $60.
Answer:
$60?

The price of a watch was increased by 20% to £144. What was the price before the increase
Answer:
120 pounds
Step-by-step explanation:
Since the new cost is 144 pounds and this is 20% more, this is 120% of the original price. Remember 100+20 = 120. To find the original price set up a proportion with these values:
Solve for the original price by cross multiplying numerator with denominator.
x(120) = 144(100)
120x = 14400
x= 120 pounds
Find a polynomial equation that has roots of -2 and double root 3
Answer:
x³ + 2x² -3x +6
Step-by-step explanation:
We need to find the polynomial whose roots are ,
-2 , √3 and √3.Say of we have zeroes as , α , β and γ , then the polynomial is ,
=> p(x) = k[ (x - α ) ( x - β) ( x - γ) ]
where k is constant. Substituting the respective values , we have ,=> p(x) = k [ ( x - (-2)) ( x - √3) ( x -√3)]
=> p(x) = k[ (x+2)(x² - 3)]
=> p(x) = k[ x(x² - 3) + 2(x² - 3) ]
=> p(x) = k[ x³ - 3x + 2x² - 6 ]
=> p(x) = k[ x³ + 2x² - 3x - 6 ]
Hence the cubic polynomial is x³ + 2x² - 3x + 6 ...........................Pls help math

Answer: 27.5
Step-by-step explanation:
The third through the fifth terms of a geometric sequence are given by a3 = 18, a4 = 27 , and a5 = 81/2
Which formula can be used to find an
Let a be the first term in the sequence. If r is the ratio between consecutive terms, then the second term is ar, the third term is ar ^2, the fourth is ar ^3, and so on, up to the n-th term ar ^(n - 1).
So the third, fourth, and fifth terms are such that
ar ^2 = 18
ar ^3 = 27
ar ^4 = 81/2
Solve for a and r :
(ar ^3) / (ar ^2) = 27/18 => r = 3/2
ar ^2 = a (3/2)^2 = 9/4 a = 18 => a = 8
Then the n-th term in the sequence is
ar ^(n - 1) = 9 (3/2)^(n - 1)
You can rewrite this by first rewriting 9 = 3^2, then
9 (3/2)^(n - 1) = 3^2 * 3^(n - 1) / 2^(n - 1) = 3^(n + 1)/2^(n - 1)
During which two moon phases would the amount of light reflected from the moon appear to be equal from Earth? Why does this occur at different times in a month?
A.
The light reflected appears the same during the new moon and full moon phases because the sun, moon, and Earth are aligned.
B.
The light reflected appears the same during the new moon and first quarter moon phases because the sun, moon, and Earth are at the same angles.
C.
The light reflected appears the same during the full moon and third quarter moon phases because the sun, moon, and Earth are at the same angles.
D.
The light reflected during the first quarter and third quarter moon phases appears equal because the sun, moon, and Earth are at right angles.
Answer:
D
The light reflected during the first quarter and third quarter moon phases appears equal because the sun, moon, and Earth are at right angles.

Two friends are to meet at the library. Each independently and randomly selects an arrival time within the same one-hour period. Each agrees to wait a maximum of fifteen minutes for the other to arrive. What is the probability that they will meet
Answer:
The probability that they will meet is 0.4375
Step-by-step explanation:
Let A and B be two friends who choose to meet the same one-hour period.Since there are 60 minutes in an hour therefore n= 60
A can wait for 15 minutes
So the probability of A to meet is given by P(A)= (15/60)= 1/4
Similarly
B can wait for 15 minutes
So the probability of B to meet is given by P(B)= (15/60)= 1/4
The probability that A cannot meet is given by 1- P(A)= 1-1/4= 3/4
Similarly
The probability that B cannot meet is given by 1- P(B)= 1-1/4= 3/4
And
The probability that both A and B cannot meet is given by = 3/4*3/4= 9/16
So the probability that both will meet = 1- 9/16= 7/16= 0.4375

Which expression is equivalent to 60 Σ n=1 (2n − 1)2 ? Check all that apply.
9514 1404 393
Answer:
B, D
Step-by-step explanation:
The quadratic expands to ...
(2n -1)² = (2n)² +2(2n)(-1) +(-1)² = 4n² -4n +1
The coefficients can be factored out of the sum, so ...
∑(4n²) = 4∑n² for example
The sum of 60 ones is 60:
[tex]\displaystyle\sum_{n=1}^{60}{1}=1+1+1+\dots+1=60[/tex]
So, the sum can be written as ...
[tex]\displaystyle\sum_{n=1}^{60}{(2n-1)^2}\\\\=\boxed{4\sum_{n=1}^{60}{n^2}-4\sum_{n=1}^{60}{n}+\sum_{n=1}^{60}{1}}\\\\=\boxed{4\sum_{n=1}^{60}{n^2}-4\sum_{n=1}^{60}{n}+60}[/tex]

The function f(x) = 2,000(1.05)x models a population of butterflies after x years. What will the population be in 7 years?
Answer:
14,700 butterflies
Step-by-step explanation:
Given the following data;
Time, x = 7 years
f(x) = 2,000(1.05)x
To find the population;
A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.
Substituting into the equation, we have;
f(7) = 2,000(1.05) * 7
f(7) = 2,100 * 7
f(7) = 14,700 butterflies
