A mechanic has two pieces of sandpaper of different sizes. Each piece is in the shape of a circle. The radius of the larger circle is 4 times the radius of the smaller circle. The area of the larger circle is how many times the area of the smaller circle?

Answers

Answer 1

Answer:

16 times

Step-by-step explanation:

difference in area = area of bigger circle / area of smaller circle

Area of a circle = πr²

r = radius

imagine the radius of the smaller circle = 1

Area of circle in terms of π= π

radius of the bigger circle = 4 x 1 = 4

Area of bigger circle in terms of π  = π4² = 16 π

16 π /  π = 16  times

write the following from least to greatest. 1/8, 2/4, 8/4, 3/15, 2whole 2/7, 20/10​

Answers

Answer:

Step-by-step explanation:

Convert each number to its decimal equivalent for easier comparison with the other numbers:

1/8 = 0.125        1 (smallest)

2/4 = 0.50         3

8/4  = 2.0           4

3/15  = 0.20        2

2 2/7 = 2.28        6  (largest)

20/10​ = 2.00       5 (next to largest)

The smallest number is 1/8 (see above), and the largest is 2.28 (2 2/7).

what is the distance from (-4, -7) to (4, 8) ?

Answers

Answer:

17

Step-by-step explanation:

We can use this formula:

[tex]\sqrt{(x2-x1)^2 + (y2 -y1)^2}[/tex] where x and y indicate the coordinates of the two points

[tex]\sqrt{4-(-4)^2 + (8-(-7)^2} = \sqrt{64 + 225} = \sqrt{289} = 17[/tex]

Answer:

17

Step-by-step explanation:

You are given two points so you use the distance formula

[tex] \sqrt{( {x 2 - x1)}^{2} + ( {y2 - y1)}^{2} } [/tex]

Substitute your points into the formula

There are two labeled weights of 4 grams and 12 grams the tree circles have the same weight what is the weight of each circle in grams

Answers

Answer:

The answer is below

Step-by-step explanation:

Let x represent the unknown weight of each of the circles, since there are three of those type of circles, hence the unknown weight is 3x.

From the diagram, the sum of the total weight at one side must be equal to the sum of the total weight at the other side so that they can be balanced, hence:

3x + 4 = 12

subtracting 4 from both sides:

3x + 4 - 4 = 12 - 4

3x = 8

Dividing through by 3:

3x/3 = 8/3

x = 8/3

The weight of each of the circle is 8/3 grams

In mathematics, a set is closed under an operation if performing that operation on members of the set always produces a member of that set. For example, the positive integers are closed under addition, but not under subtraction: 1 − 2 is not a positive integer even though both 1 and 2 are positive integers.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

The table

Now,

Looking at the table, we can see that each input value is paired with only one output value, so the relationship is a function. We can also see that the difference between the output values is not constant, so the function is not linear. The quotient of the output values is not constant either, so the function is not exponential. The quotient of the output values does not change in a predictable way, so the function is not logarithmic.

Therefore, by the function the answer will be quadratic.

(240 + x) ÷5 = 51

240 + x = 255

x = 15

The mean of the 5 data is 127.

(100 + 112 + 98 + 235 + x) ÷5 = 127
