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.
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%

Slope, Explanation needed please HELPPPPPP
Answer: 2/25
Step-by-step explanation:
The formula to find the slope is (y2-y1)/(x2-x1)
If you plug in the numbers, you get (18-14)/(30-(-20))
Solve the expression and you get 4/50 = 2/25
So your answer is 2/25
Answer:
the slope is 2/25. use the formula m= y2-y1/x2-x1 and plug in the points
Dean loves rocks! He has 666 pieces of granite, 333 pieces of marble, 141414 pieces of sandstone, and 111 pieces of slate.
What is the ratio of pieces of sandstone to pieces of marble in Dean's collection?
Answer:
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.
Hope this helps! :)

The point (1, –5) is reflected across the y-axis. A coordinate plane. What are its new coordinates?
(–1, 5)
(1, –5)
(–1, –5)
(1, 5)
Explanation:
The reflection rule we use is
[tex](x,y) \to (-x, y)[/tex]
when we want to reflect over the y axis. The x coordinate flips from positive to negative, or vice versa, while the y coordinate stays the same.
Therefore, [tex](1, -5) \to (-1, -5)[/tex]
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?
======================================================
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 = 12Those 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.
Bob is packing a suitcase to take on an airplane. A suitcase and its contents can weigh at most 50 pounds before the airlines charge extra fees. Bob's suitcase weighs 10 pounds when it is empty, so he can put 40 pounds of clothes in the suitcase. Bob's shirts weigh 0.5 pounds each and his pants weigh 2 pounds each.
(1)Write an equation that would model how many pounds of clothing Bob can pack.
(2)Rewrite the equation to model the number of pants Bob can pack in terms of the number of shirts.
Answer:
1. 10x + 40 = 50
2. 10x + 2 + 0.5 = 40
Step-by-step explanation:
1. If bob's suitcase is 10lb. by itself then that is 10.
His limit of content and suitcase is 50lb.
His shirts weigh 0.5lb each.
His pants weigh 2lb each.
10x + 40 = 50
2. 10x + 2 + 0.5 = 40

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
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.

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!!!
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.
