No , because when we are adding it we don't get the number that's divisible by 3Yes ,it is divisible by 9 .We can do this by adding all the numbers 3+9+7=27Yes it is divisible by both 3 and 9 ,because when we are adding we get 1+8+6+4+2+6=27.And 27 is divisible in both the tables Please mark me as the Brainliest!!if the answer helped you( -20 , 14 ) and ( 30, 18)
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! :)

A company manufactures two types of cabinets, type 1 and type 2. It produces 110 total cabinets each week. Last week, the number of type 2 cabinets produced exceeded twice the number of type 1 cabinets produced by 20. If x is the number of type 1 cabinets produced and y is the number of type 2 cabinets produced, the system of equations that represents this situation is x + y = 110 and y = 2x + 20. The number of type 2 cabinets produced last week is . This number exceeds the number of type 1 cabinets produced during the week by .

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]
A line passes through the points (–3, –4) and (6, 2).
Answer:
-3
Step-by-step explanation:
The x-intercept is 3, here's why
First, you need to get the slope
y2-y1
--------
x2-x1
You should get 2/3
Next, you need to use y=mx+b
y= 2/3x+b
2= 2/3(6)+b You get 6 and 2 from the coordinates
Once this is worked out you'll get y=2/3x-2
To get the x intercept you need to set y equal to 0
0=2/3x-2
Add 2 to each side
0-2 = 2/3x
Multiply each side by 3/2 to isolate x
-2 *3/2 = 2/3x * 3/2
-3 =x
The x intercept is -3

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.

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.

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%

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
