Answer:

A)6x-18, B)They are not equal, since 6xx18 is not equal to 6x-9

Step-by-step explanation:

2(3x-9) = 2(3x)-2(9) =6x-18.

Answer:

Step-by-step explanation:

Let’s mark the Triangle Points as Point A, Point B, Point C.

Point A = 1x°

Point B = 2x°

Point C = 3x°

We know that the Angle Sum of a Triangle is equal to 180°.

So, Point A + Point B +Point C = 180°

   = 1x° + 2x° + 3x° = 180°

   = (1 + 2 + 3)x° = 180°

   = 6x° = 180°

   = x° = (180/6)°

   = x° = 30°

|  —                                 —  |

|   Point A = 1 * 30° = 30°    |         ⇒

|   Point B = 2 * 30° = 60°   |         ⇒          Only Extra Information

Answer:

a: y = - 7

c: x = -10

e: x = 2

g: x = -2

i: y = 9

k: y = -2

m: y = -6

Step-by-step explanation:

a: Subtract 5 on both sides

c: Add 5 on both sides then combine like terms

e: Combine like terms then divide by 5

g: Combine like terms then divide by 11

i: Add 2 on both sides

k: Combine like terms then divide by 7

m: Divide by three(won't add the number for some reason)

I want to know about exponent and surds

Explanation:

Let's rewrite each given fraction with a common denominator of 5*7 = 35.

1/5 = (1/5)*(7/7) = 7/35

1/7 = (1/7)*(5/5) = 5/35

Then we can see that 6/35 is between 5/35 and 7/35, since 6 is between 5 and 7.

Put another way:  5/35 < 6/35 < 7/35 since 5 < 6 < 7

This then means 1/7 < 6/35 < 1/5

Therefore, Maria's claim is incorrect.

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

Answer: A C and D

Step-by-step explanation:

What I did was look at point A, we see it starts at (-8, 6) this means that if it were to be shifted right 9 and down 4 we would get (1, 2). so, all the answers claiming that the points were shifted right 9 and down 4, or x+9 y-4 are correct.

Answer:

Volume of composite is 483  \(mm^3\)

Step-by-step explanation:

We need to add the volume of a rectangular prism (7 mm x 12 mm x 3 mm) to a semi-cylinder (of radius 3.5 mm and height 12 mm):

Volume of the prism = 7 x 12 x 3 \(mm^3\)  = 252 \(mm^3\)

Volume of the semi-cylinder =  \(\frac{\pi\,\,R^2\,\,H}{2} = \frac{\pi\,\,(3.5)^2\,\,(12)}{2} =230.907 \,\,mm^3\)

Therefore the sum of both volumes gives:

(252 + 230.907) \(mm^3\) = 482.907  \(mm^3\)

WHich can be rounded to the nearest whole number as: 483 \(mm^3\)

Answer:

J' (-2, 2.5), K' (1, 2.5) L' (1, -2.75)

Step-by-step explanation:

With a scale factor of 1/2=.5 you can simply multiply all coordinates by .5 (or divide by 2)

J (-4,5) x 1/2= (-2, 2.5)

K (2,5) x . 5 = (1, 2.5)

L (2, -5.5) /2= (1, 2.75)

you can put :they both have whole numbers

Answer:

The result of this dilation is an enlargement. The scale factor is 3.

Step-by-step explanation:

The original figure has coordinates (0,0), (1,0), (2,0), (2,1), and (1,1). The dilated figure has coordinates (0,0), (3,0), (6,0), (6,3), and (3,3). Notice that the distances between corresponding points in the original and dilated figures are all multiples of 3. This means that the dilation has a scale factor of 3.

In general, a dilation is an enlargement if the scale factor is greater than 1, a reduction if the scale factor is less than 1, and a congruent image if the scale factor is equal to 1.

Answer:

circumference: 37.7

area: 113.1

Step-by-step explanation:

for the future look up '___ of a circle'

and enter the radius (if u are given the diameter divide it by 2)

Answer:

circumference = 37.68 (37.7 if you're rounding it)

Area = 113.04 (113.1 if you're rounding it)

Step-by-step explanation:

The formula for circumference is C=2πr (2 times pi times radius)

If the diameter is 12, the radius is 6.

2 x 3.14 x 6 = 37.7

The formula for area is A=πr2 (pi x radius to the second power)

The radius is 6. Six to the second power is 36.

36 x 3.14 = 113.04

Answer:

729

Step-by-step explanation:

Alright so our 2 big things here are order of operations and laws of exponets.

1st we need to find (-3)^4 and (-3)^2.

-3 raised to 4 is 81, and -3 raised to the 2nd power is 9.

So now our simplified equation is (81/9)^3.

Now we use the power of a quotient rule from the laws of exponets (look this name up and you'll easily find it).

So now our equation is (81^3)/(9^3). This equals 729.

Hope this helps!

Answer:

Since 7 is less than 32 your long division is done. You have your answer: The quotient is 15 and the remainder is 7.

So, 487 ÷ 32 = 15 with a remainder of 7

For longer dividends, you would continue repeating the division and multiplication steps until you bring down every digit from the dividend and solve the problem.
