Owen measured the diameter and circumference of four circles. Which one of his measurements is the least accurate?


Coin


Flying disc


Jar lid


Flower pot

Answers

Answer: Flying disc

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula for each object:

Circumference(C) = π x diameter

Coin  

Diameter = 3  

Circumference (measured) = 10  

C (calculated) = π x d = π x 3 = 9.42  

10≅9.42

Flying disc  

Diameter =23

Circumference (measured) = 28  

C (calculated) = π x d = π x 23 = 72.25

72.25 ≠ 28

Not accurate

Jar lid

Diameter =8

Circumference (measured) =25  

C (calculated) = π x d = π x 8= 25.13

25 ≠ 25.13

Flower pot

Diameter =15

Circumference (measured)=47

C (calculated) = π x d = π x 15 = 47.12

47 ≠47.12

Feel free to ask for more if needed or if you did not understand something.  

Answer:

Jar lid

Step-by-step explanation:

If you look up the diameter and circumference of the jar lid, it would give you an answer and if you compare it the answers are diffrent. So what you wan to put is: "I know that the Jar lid is wrong because For a  jar lid, the diameter is 8, but for the circumference its is 2.5, and on the chart the dimeter is 8 BUT the circumference is 2.5" Hope this help. :)

-8a/9

Answers

Answer:

-8a times 1/9

Step-by-step explanation:

This can be thought of as -8a/1 times 1/9. (1/9 is the reciprocal of 9, so were just pulling the fraction apart)

The expression is as fraction times the variable is (-8/9)a.

What is a fraction?

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

In another word, the fraction is the division of the two numbers but the division is not wholly complete.

As per the given,-8a/9

The variable in the above fraction is a.

Thus, (-8/9)a will be the representation in terms of the product of constant and variable.

Hence "The expression is as fraction times the variable is (-8/9)a".

Solve for x. 9x=3x−3

Answers

Answer:

x=-1/2

Step-by-step explanation:

9X = 3X + -3

Reorder the terms:

9X = -3 + 3X

Solving

9X = -3 + 3X

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '-3X' to each side of the equation.

9X + -3X = -3 + 3X + -3X

Combine like terms: 9X + -3X = 6X

6X = -3 + 3X + -3X

Combine like terms: 3X + -3X = 0

6X = -3 + 0

6X = -3

Divide each side by '6'.

X = -0.5

Answer:

x = -0.5

Step-by-step explanation:

In an equation, the goal is the isolate the variable. We do this by undoing the operations done to result in the given equation.

Step 1: Subtract 3x

6x = -3

Step 2: Divide by 6

The value of 10th of a quarter of 1600 is 40.

What is a quarter of a number?

A quarter of the number is 1/4 times of the number i.e. times of the number.

Quarter of x= (1/4)*x= 0.25 * x

Given in the question that we have to calculate 10th of a quarter of 1600.

Before that we have  to first calculate a quarter of 1600 which is calculated by using the above formula

quarter of 1600= (1/4)*1600= 0.25* 1600= 400

Now we have to calculate 10th of a quarter of 1600 i.e. 10th of 400.

10th of 400= (1/10) * 400= 40

Therefore the value of 10th of a quarter of 1600 is 40.

what is the equation of a line that passes through the points -2 -2 and has a slope of four

Answers

Answer:

y = 4x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4, thus

y = 4x + c ← is the partial equation

To find c substitute (- 2, - 2) into the partial equation

- 2 = - 8 + c ⇒ c = - 2 + 8 = 6

y = 4x + 6 ← equation of line

Answer:

J = 45

Step-by-step explanation:

Since the two sides are the same, the base angles must be equal.  Since it is a right triangle, the two angles share 90 degrees

What is the area of the garden in Plan B? (Type the numeric answer only).

Answers

Answer:

241.5 ft^2

Step-by-step explanation:

First, find the area of the deck. A = LW.  L = 20, W = 16.

20 x 16 = 320.

Now that we have found the area of the deck, let's find the area of the garden. A = [tex]r^{2} \pi[/tex].   r = 5.  

A = (pi)5^2

A = 25(pi)       pi =  3.14

A = 78.5

Since the deck will not cover the garden, we must subtract the area of the garden from the total area of the deck.

320 - 78.5 = 241.5
