The sales tax for an item was $8.80 and it cost $440 before tax.
Find the sales tax rate. Write your answer as a percentage.

Answers

Answer:

Step-by-step explanation:

In non-mathematical form, the question is asking $8.80 is what percent of $440. N will equal the percent. So, you would set up the equation like this: 20 = N · 440

You need to solve the equation.

20/440 = N · 440/440

0.045 repeating = N

Rounded, the sales tax rate would be 4.5%

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Harrison has 70 CDs in his music collection. If 10% of the CDs are country music and 60% are pop music.

The percentage of the other CDs will be:-

P = 100 - 60 - 10

P = 30%

The number of the other CDs will be:-

Number = 70 x 30%

Number = 70 x ( 30 / 100 )

Number = 21

The Kirkland family is buying a new living room set that costs $1,495.

They are going to put a down payment of $400 and then put the rest on

their credit card that has an annual interest rate of 28%. If they pay off

the furniture in 1 year, how much interest would they pay?

Answers

Answer:   173.04 dollars

======================================================

Explanation:

The down payment is $400, so that means they must pay back 1495-400 = 1095 dollars. Let L = 1095 be the amount loaned

The annual interest rate is 28% which means r = 0.28; the monthly interest rate is i = r/12 = 0.28/12 = 0.02333 approximately

There are 12 months in a year, so n = 12 is the number of payment periods

----------------------------------------

In summary so far, we have

L = 1095i = 0.02333 (which is approximate)n = 12

Those values will be plugged into the monthly payment formula below

M = L*( i*(1+i)^n )/( (1+i)^n - 1 )

M = 1095*( 0.02333*(1+0.02333)^12 )/( (1+0.02333)^12 - 1 )

M = 105.671914631108

M = 105.67

The monthly payment is $105.67

If they have a monthly payment of $105.67, and they pay that for 12 months, then 12*105.67 = 1,268.04 dollars is the amount of money they pay back to the credit card company.

The total amount of interest would be 1,268.04 - 1,095 = 173.04 dollars

Side note: the formula is a complicated ugly mess, so it's understandable to use calculators that already have the formula built in. Many websites offer free calculators that do this.

What is the total surface area of this rectangular pyramid?
A rectangular pyramid. The rectangular base has a length of 12 feet and width of 6 feet. 2 triangular sides have a base of 12 feet and height of 8 feet. 2 triangular sides have a base of 6 feet and height of 9.5 feet.
_____________ square feet
HELP PLS!!!

Answers

Answer:

225 square feet

Step-by-step explanation:

the base of the pyramid would be 76 ft², since 12*6=72. Then you get the surface area of the sides. 2 of the sides would be 48 ft², since (12*8)/2=48. The other 2 sides would be 28.5 ft², since (6*9.5)/2-28.5. Then you just add the surface areas of all the sides; 76+48+48+28.5+28.5 to get 225.

At Sally's Diner, combo meals come with either chips or fries. Of the 115 customers on Friday, 80% ordered combo meals. Of these 3/4 had fries. How many customers on Friday had fries with their meals?

A. 69
B. 72
C. 86
D. 92

Answers

Answer:

A: 69

Step-by-step explanation:

80% of 115 customers had combos. To find out the amount that had combos, we multiply the amount of customers by percentage. 115 * 80% (0.8) is 92. 92 customers had combo meals. 3/4 of them had fries with it, and 3/4 is 75% in percent form. We multiply 92 by 75% to get the amount that had fries. 92 * 75% (0.75) is 69. There. Sally's Diner had 69 of Friday's customers order fries with their combo meals.

115 x .80% = 92

92 x .75% = 69

Answer : A. 69

What is the ratio of pieces of sandstone to pieces of marble in Dean's collection?

Answers

The ratio of sanstone to marble is... 141414 : 333

All you have to do is look at how much sandstone Dean has and how much marble he has, then put the amount of sandstone infront of the amount of marble because in the question it says what is the ratio of sandstone to marble and you see that sandstone is first.
