Debbie Redden has a 25%-off coupon and is purchasing a
2.5 gallon can of primer sealer paint that has a regular price
of $39.99.
a. What is the markdown?
b. What is the sale price?
c. What is the sale price using the percent paid method?

Answers

a) the markdown is $9.99
b) original sale price is $39.99
c) after using the coupon the price would be $29.99

in order to find this out you would first divide the original price of 39.99 by 100 in order to find out what 1% is. Then you would multiply this number by 25 to find out what 25% is. Then you would subtract the original amount of 39.99 by the 25% amount in order to find out how much is taken off

Volunteers at Sams school use some of the student councils savings for a special project.They buy 4 backpacks for $9 each and fill each backpack with paper and pens that cost $5.By how much did the student councils savings change because of this project?

Answers

Answer: The student councils savings change by $41.

Step-by-step explanation:

Number of backpacks = 4

Cost of each backpack = $9

Paper and pen costs = $5

Total spending = (Number of backpacks ) x (Cost of each backpack ) + (Cost of paper and pen)

= $ (4 x 9 +5)

= $ 41

Hence, the student councils savings change by $41.

Convert the following repeating decimal to a fraction in simplest form.
.78

Answers

Answer:

78/100

Step-by-step explanation:

Since .78 is in the hundredths place just move the decimal two places to the right then put it over 100. But idk if you mistyped this because .78 is not a repeating decimal

Answer:

6/9

Step-by-step explanation:

Change 0.7878 to a fraction.

Let n = 0.7878... Multiply both sides by 100 (by 100 when there are two repeating decimal digits)

100n = 78.7878... Subtract n from 100n.

99n = 78 Divide both sides by 99

n = 78/99 but n is 0.7878..., so

0.7878... = 78/99

Similarly with 0.66...

Let n = 0.66... Multiply both sides by 10 (by 10 when there is only one repeating digit)

10n = 6.66... Subtract n from 10n.

9n = 6 Divide both sides by 9.

n = 6/9 but n is 0.66..., so

0.66... = 6/9

If
[tex] \cos(330) = \frac{ \sqrt{3} }{2} [/tex]
Prove that:
[tex] \tan(165) = \sqrt{3} - 2[/tex]
Please solve this question.​

Answers

Answer:  see attachment

Step-by-step explanation:

Given: cos 330 = √3/2

Prove that tan (165) = √3 - 2

Step-by-step explanation:

cos330° = cos(360° - 30°) = cos(2π - 30°)

Using, cos(2π - x) = cosx, x < 90°

=> cos(2π - 30°)

=> cos(30°)

=> √3/2 , proved

(ii): tan(165°) = tan(180° - 15°) = tan(π - 15°)

Using, tan(π - x) = - tanx

=> tan(π - 15°)

=> - tan15°

=> - (-√3 + 2)

=> √3 - 2 proved

For tan15° :

Using, tan2x = 2tanx/(1 - tan²x)

tan30° = 2tan15°/(1 - tan²15°)

1/√3 = 2tan15° / (1 - tan²15°)

1 - a² = 2√3 a {a = tan15°}

Solving this we get, a = -√3±2

As a = tan15°, it can't be -ve, thus

a = tan15° = -√3 + 2

The company wants to build two additional stores. Your executive team has decided that rather than expand to new markets, they want Better Beans to begin opening additional stores in existing markets. While this will create cannibalization in the short term, it will create marketing and operating efficiencies as more stores are opened in each city.As a scrappy and growing startup, Better Beans does not yet have access to complex marketing analytics software. Fortunately, you are an expert at gathering market data from inside and outside the company and crunching accurate numbers with nothing more than an Excel spreadsheet.You have been tasked with calculating the two best markets for opening an additional store. You have already calculated two things that allow you to estimate the net additional revenue in each market after adding a second store:Revenue for a second store in each marketThe revenue lost from estimated cannibalization at the first store.Important note: Due to the high investments already made in existing stores, management has specified that any market where cannibalization is 25% or more should be eliminated from consideration.1.
