I spent 80% of my money and had $12 left. How much money did I have to start ?

Answers

Answer 1
Answer: If you spent 80% that means you have 20% left, we'll use B as variable

20% x B = 12
0.20/0.20 x B = 12/0.20
B = 60

Find the slope of the line through the points (17,-6),(-11,7)

Answers

y2-y1/x2-x1
basically its the difference between the y's and x's

Final answer:

The slope of the line through the points (17,-6),(-11,7) is calculated using the formula 'm = (y2 - y1) / (x2 - x1)'. Substituting these values into the formula yields a slope of -13/28.

Explanation:

In mathematics, the slope of a line through two distinct points can be calculated using the formula 'm = (y2 - y1) / (x2 - x1)'. This formula represents the change in y (vertical axis) divided by the change in x (horizontal axis).

Given the two points (17,-6) and (-11,7), we can substitute these values into the slope formula:

m = (7 - (-6)) / ((-11) - 17) = 13 / -28 = -13/28.

Therefore, the slope of the line through the points (17,-6),(-11,7) is -13/28.

What is arithmetic?

Arithmetic is a branch of mathematics that deals with the study of numbers, their properties, and their operations. It involves the basic operations of addition, subtraction, multiplication, and division, as well as more advanced operations such as exponents, roots, logarithms, and trigonometric functions.

Here,

To multiply 1000 and 20, we can follow these steps:

Step 1: Multiply the one's place digits

0 (one place digit of 1000) multiplied by 0 (one place digit of 20) equals 0.

Step 2: Multiply the tens place digits

0 (tens place digit of 1000) multiplied by 2 (tens place digit of 20) equals 0.

Step 3: Multiply the hundreds place digits

0 (hundreds place digit of 1000) multiplied by 0 (hundreds place digit of 20) equals 0.

Step 4: Multiply the thousands of place digits

1 (thousands place digit of 1000) multiplied by 2 (thousands place digit of 20) equals 2000.

Step 5: Add up the products obtained in steps 1-4.

0 + 0 + 0 + 2000 = 2000.

Therefore, 1000 times 20 equals 2000.

at Mary's party 4/8 of the guest had chocolate ice cream and 3/8 of the guest had strawberry ice cream . what fraction of the ice cream was either chocolate or strawberry

Answers

7/8 because you add 4/8 and 3/8 together which is equal to 7/8.
7/8 I believe, as 4/8 had chocolate ice cream and 3/8 had strawberry and we don't know what the remaining 1/8 had, so just add who had strawberry and who had chocolate together and that will give you the probability.

How do you find the circumfrence and area of a circle? Examples please or a link to a website.

Answers

Area or a circle
A= 3.14 (pi) multiplied by the radius to the second power
So if a circles radius is 3 cm it would be pi multiplied by 9 which equals 28.27 cm2
Circumference
C= pi multiplied by the diameter
To find the corcumference of the circle the formula is 2(pi)r
to find the area of the circle the formula is (pi)(r)(r)
