Answer:
profit = 129.63% (to the nearest hundredth) as a percent of the price the store paid for the book
Step-by-step explanation:
Use the percentage change formula:
percent change = [ (difference between the initial value and the final value) ÷ initial value] x 100
= [ (6.20 - 2.70) ÷ 2.70 ] x 100
= [ 3.5 ÷ 2.70 ] x 100
= 37/27 x 100
= 129.6296296...
= 129.63% (to the nearest hundredth)

You have a coupon for 30% off your total order.
You buy a shirt, shoes, and a hat. The shirt is
$15, the shoes are $65, and the hat is $14. The
tax rate is 6%, taken on the subtotal. How much
do you pay?
Answer:
you pay $69.74
Step-by-step explanation:
total cost without coupon: 15+65+14 = 94
apply the 30% discount ⇒ 94 × .30 = 28.20
subtract the savings ⇒ 94.00 - 28.20
total, after coupon, before tax ⇒ 65.80
apply 6% tax to 65.80 ⇒ 65.8 × .06 ⇒ 3.94
add tax to cost after coupon ⇒ 65.80 + 3.94
you pay $69.74

3(2x+1) =9 Show work please
Answer:
x=1
Step-by-step explanation:
Given
3(2x+1)=9
Distribute left side
3(2x+1)=9
3(2x)+3(1)=9
6x+3=9
Subtract 3 on both sides
6x+3=9
6x+3-3=9-3
6x=6
Divide both sides by 6 to isolate "x"
6x=6
6x/6=6/6
x=1
Final answer
x=1
Answer:
x=1
Step-by-step explanation:
3(2x+1)= 9
(3x2x) + 1 =9
6x+3=9
6x-3=9-3
6x=6
6x/6=6/6
x=1
Check your work:
3(2(1)+1)=9
3(2+1)=9
6+3=9
9=9
Mike buys a water heater online for $241. If shipping and handling are an additional 24% of the price, how much shipping and handling will Mike pay?
Answer:
$57.84
Step-by-step explanation:
Note:
24% = .24
Question to Answer:
How much shipping and handling will Mike pay?
solution:
241 x .24 = 57.84
241 + 57.84 = 298.84
Hence Mike will pay $57.84 for shipping and handling.
Mike will pay $298.84 all together {Include shipping and handling}

This year, Brad is a photographer for his school newspaper. He takes 5 color photos for every 2 black-and-white photos.
Complete the table.
Graph the data from the table.
The sequence of number of color and black and white photos would look like this: 5 color/2 black and white, 15 color/6 black and white, 20 color/8 black and white, and 30 color/12 black and white.
How to calculate the number of photos?To calculate the number of photos that follow in the sequence, it is necessary to take into account that for every 5 in color there are 2 in black and white.
We can also rely on the graph since it shows the constant relationship between both values. In it we can identify the equivalence between both types of photos.
According to the above, the sequence of number of color and black and white photos would look like this:
5 colour/2 black and white.15 colour/6 black and white.20 colour/ 8 black and white.30 colour/12 black and white.Learn more about graph in: https://brainly.com/question/14375099
How do you Multiply Complex Numbers? I used a calculator that shows work and it mentioned something called the foil method which gave -20+16i+15i+12 when I put (4-3i)(-5+4i). What is the foil method
The FOIL method is the formula that is used when multiplying 2 binomials, where
(a+b)(c+d) = a(c+d) + b(c+d) = ac + ad + bc + bd
Using the formula above, apply the foil method.
4(-5+4i) - 3i(-5+4i)
4(-5) + 4(4i) + (-3i(-5)) + (-3i(4i))
-20 + 16i + (15i) + (-12i^2)
-20 + 16i + 15i - 12i^2
Since i^2 = -1, then
-20 + 16i + 15i - 12(-1)
-20 + 16i + 15i + 12
Hope this helps.

Let f (x) = 1/(x^2) What conclusion can be made about the maximum and minimum values of function f on the interval [–5, 5] using the extreme value theorem?
Answer:
The function is not continuous on the interval, so the extreme value theorem does not apply
Step-by-step explanation:
Recall that the Extreme Value Theorem states that if a function is continuous on a closed interval [a,b], then the function must have a maximum and a minimum on the interval. Given that the function is discontinuous at x=0 which gives off a vertical asymptote, this does not meet the requirements of the theorem.
Is the square of a complex number always a real number? Explain how, please I would like to finish this tonight.
Answer:
The absolute square of a complex number is calculated by multiplying it by its complex conjugate. This give the magnitude squared of the complex number. The absolute square is Always Real. We will use complex exponentials all the time.
Answer:
Step-by-step explanation:
I don't thing it is very often unless it is of the form
5i
When you square that, you get a real number (5i)^2 = - 25
On the other hand when you have a binomial like
3 + 2i
and you square that, the result is still a complex number.
(3+2i)(3+2i) = 9 + 6i + 6i + 4i^2 = 5 + 12i

Write the percent as a decimal. 13%
Answer:
0.13
Step-by-step explanation:
to change a percent to a decimal you just move the decimal 2 places to the left
Answer:
13% = 0.13 in decimal form.
Step-by-step explanation:
Percent means 'per 100'. So, 13% means 13 per 100 or simply 13/100.
If you divide 13 by 100, you'll get 0.13 (a decimal number). Read more below on this webpage.
As you can see, to convert from percent to decimal just divide the percent value (13) by 100, and remove the "%" sign.

-9+-6 rational or irrational
Answer:
Rational
Step-by-step explanation:
-9+-6=-15
A rational number includes any whole number, fraction, or decimal that ends or repeats. An irrational number is any number that cannot be turned into a fraction, so any number that does not fit the definition of a rational number.
Answer:
All integers are rational numbers science they can be divided by 1, which produces a ratio of two integers. That means-9+-6 is a rational number
A certain rectangle has length 2x + 1 and width x + 1, find an expression for its area. You
answer should be in the form of a quadratic expression. Why do you think it's called this?
Answer:
2x² + 12x + 10
Step-by-step explanation:
Area of a rectangle = width x length
Therefore,
Area = (x + 1)(2x + 10)
Expand the brackets: 2x² + 10x + 2x + 10
Combine like terms: 2x² + 12x + 10
A quadratic expression is an expression with the variable with the highest power of 2
I need help Please! Please CAN SOMEONE ANYBODY HELP ME I NEED IT!
Answer:
1. Dots
2.Blank
3. Stripes
4. Stars
Step-by-step explanation:
Well the total is 30 and we just have to see the fraction of each time in landed on a specific part of the spinner. So first the probability of landing on dots is 6/30 = 1/5
Then the experimental probability of getting a blank is 8/30 = 4/15
Continuing in the same manner getting stripes would have a chance of 12/30 which is 2/5
Finally I'm gonna let you think about how I got the last one and why I did what I did :)
