Answer:

I believe the answer to your question is 38.

Step-by-step explanation:

Here is what I did: First, I found the radius, and to do that, I did 12 divided by 2, which gave me 6. then I did 6 divided by 2, to find the radius, of the radius I just found.  which gave me 3, then I did 3 times 12, which gave me 36, so the answer should be 38 :)

Answer:

14/9

Step-by-step explanation:

(1+1/3)^2 −2/9

Add the terms in the parentheses

(3/3+1/3)^2 −2/9

(4/3)^2 −2/9

Exponents

16/9 - 2/9

14/9

For this problem, PEMDAS is really important, because we need to make sure that we are doing things in the correct order.

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

The first thing we need to do is the math inside the parentheses:

(1 + 1/3) = 1 + 1/3 = 4/3

Next, we square the parentheses:

(4/3)² = 16/9

Now, all we need to do is subtract!

16/9 - 2/9 = 14/9

If you need to make it a proper fraction, your answer is 1 5/9, but if you leave it improper then 14/9.

Answer:

10/13, 2/3, 7/11, 3/5, 5/9

Step-by-step explanation:

5/9 , 7/11, 3/5, 2/3, 10/13

Changing to decimal form

.5555(repeating), .636363(repeating), .6 , .666(repeating) ,.769230769

The largest is 10/13

Then 2/3

Then 7/11

Then 3/5

The smallest is 5/9

Answer:

B would be the answer.

Step-by-step explanation:

Because 1 x 35 is 35. 35 x 2 is 70. 35 x 3 is 105. And so on. :> Good luckk

Answer:

i think the answer is 25pi

The circumference of the circle is 26π, having center at point (3,-7) and a point on the circle is (8,5).

A circle is a round-shaped picture, that has no corners or edges, in geometrical figure it has the largest area for any given length or parameter.

The point of center of the circle 0 = (3, -7).

And the point on the circle C = (8, 5).

The radius of the circle = the distance between center and point on circle

Use the formula to find distance between two points,

The distance between two points A(x₁, y₁) and B(x₂, y₂)

Distance

= √(x₂ - x₁)² + (y₂ - y₁)²

= √(8-3)² + (5 + 7)₂

= √5² + 12²

= √25 + 144

= √169

= 13

The radius of the circle r = 13.

The circumference of the circle = 2πr = 2 x π x 13 = 26π.

The circumference of the circle is  26π.

Answer:

-22 - 2 = -24

Step-by-step explanation:

The answer space already has the minus sign so we can infer the number line is showing subtraction.

We start from -22 and jump to -24. This number line skip counts by 2 and we only jumped one unit, it means we subtracted by 2.

So we subtracted -22 by 2 and it is equal -24:

-22 - 2 = -24

Answer:

-0.3n + 0.6

Step-by-step explanation:

if we write out the entire expression we have:

0.5n - 0.3 - 0.8n + 0.9 (two negative signs create a positive sign)

then we add and subtract

and receive

-0.3n + 0.6

Answer:

-0.3n + 0.6

Step-by-step explanation:

We can eliminate the parentheses, obtaining:

0.5n - 0.3 - 0.8n + 0.9

and then combine like terms, obtaining:

-0.3n + 0.6

Here

Angle R = Angle T

UR = ST

Step-by-step explanation:

Answer:

C. -8

Step-by-step explanation:

We have to solve the inequality by isolating x.

-5x - 12 < 33

Add 12 to both sides.

-5x < 45

Divide both sides by -5 (remember to flip the sign when dividing by a negative).

x > -9

The least possible value for x that satisfies this inequality is -8.

Answer:

560

Step-by-step explanation:

140 ÷ 5 = 28

28 x 20 = 560

please mark me as brainliest and correct me if im wrong

You could either use the propotional method or unitary method, but I am going to be using the porpotional method since it is more quick.

Step 1

So first we would convert  the numbers givin into a fraction by putting 5 over 140 and 20 over x which is the question mark.

Step 2

Then we would cross multiply, so multiply numbers that are diagonal to each other .140 would multiply with 20 and 5 would multiply with x.

Step 3

After we multiply (we do not multiply 5 with anything so it is just 5)we would have the equation , x times 5=2800. Since  we need to isolate x we would take 5 and put it under 2800 so it would be 2800 divided by 5.

Step 4

After we divide 2800 by 5 we would have 560 which equals to x , making it the ounces needed to feed 20 animals at the shelter .

Summarise

To briefly explain this the way to find the answer would be 20x40 divided by 5.

Answer:

The legnth of side AB would be 3 units

Step-by-step explanation:

First, you would determine that both point A and point B would have the same y-coordinate of 1.   Then you would determine the difference between the x values of points A and B.  Since 5 (the x-value for B) minus 2 (the x-value for A) is 3, the legnth of side AB would be 3 units.

4xy exponent 7/2xy exponent 6

Answer:

Step-by-step explanation:

First expand the numerator by distributing in the 2 outside the parenthesis to get

[tex]\frac{16x^6y^4}{2x^6y}[/tex] and now, working on one thing at a time, we will divide:

16     x⁶     y⁴

2      x⁶      y    

I separated each set of like expressions to make it easier to see. First divide the numbers, 16 by 2:

8       x⁶      y⁴

        x⁶      y

the x's cancel out (divide to a 1):

8      y⁴

       y

and by the rules for dividing like bases, we will subtract the exponents, lower from upper to get, finally:

8y³
