Consider two circular swimming pools. Pool A has a radius of 16 feet, and Pool B has a diameter of 9.94 meters. Complete the des
Dmitry_Shevchenko [17]

Answer:

Pool B has the greater circumference.

Step-by-step explanation:

Pool A has a radius of 16 feet, and Pool B has a diameter of 9.94 meters.

We want to see which pool has a greater circumference.

The circumference of a circle is the distance around a circle or the total length of a circle, and it is given as:

C = 2\pi r

where r = radius of the circle

So that our comparison can be accurate, let us put the dimensions of both pools in a single unit, metre.

The radius of pool A is 16 feet.

1 foot = 0.305 metres

16 feet = 4.88 metres

The radius of pool A in metres is 4.88 metres

CIRCUMFERENCE OF POOL A

C = 2 * \pi * 4.88 = 30.66 m

CIRCUMFERENCE OF POOL B

C = 2 * \pi * 9.94 = 62.45 m

As we can see, pool B has the greater circumference.

TRIANGLE ABC IS DILATED BY A SCALE FACTOR OF 0.5 WITH THE ORIGIN AS THE CENTER OF DILATION, RESULTING IN THE IMAGE TRIANGLE A'B'
const2013 [10]

Answer: The length of the line B'C" is 1 unit.

Step-by-step explanation:

Given: Triangle ABC is dilated by a scale factor of 0.5 with the origin as the center of dilation , resulting in the image Triangle A'B'C'.

If A (2,2), B= (4,3) and C=(6,3).

Distance between (a,b) and (c,d): D=\sqrt{(d-b)^2+(c-b)^2}

Then, BC =\sqrt{(3-3)^2+(6-4)^2}

\\\\=\sqrt{0+2^2}\\\\=\sqrt{4}\\\\=2\text{ units}

Length of image = scale factor x length in original figure

B'C' = 0.5 × BC

= 0.5 × 2

= 1 unit

Hence, the length of the line B'C" is 1 unit.

Given B is the midpoint of AC, what is AC ?<br><br> A. 54<br> B. 27<br> C. 6<br> D. 18
lubasha [3.4K]
A. 54

The fact that B is the midpoint means that AB = BC so you can set up the equation of
4x+3 = 3x+9

Then solve for x by subtracting 3 from the left and 3x from the right to get

X=6

Finally, plug that back in to your line and solve for the total value

4(6) + 3 + 3(6) +9 = 54
