17/22 as a decimal rounded to the nearest hundred

Mathematics
1 answer:
Elenna [48]3 years ago
8 0

Answer: 0.77

Step-by-step explanation:

17/22 = 0.7727

To the nearest hundredth in math means to round off to two decimal places, so here, 2 is less than 5, and so the final answer is

= 0.77

HELP ME PLZZZZ!!!!!!!!!!!!!!!!!!

the radius of the distance between the middle point of the circle and the outside, we have the diameter which is 6 so the <u>radius will be 3</u>

slant height is

\sqrt{r^2+h^2}

h is 4.7 and r is 3

\sqrt{3^2+4.71^2} \\5.58427

<u>slant height is 5.58427</u>

lateral surface area

\pi r\sqrt{h^2+r^2}

\pi (3)\sqrt{4.71^2+3^2} \\52.63053

<u>lateral surface area is 52.63053</u>

total surface area

\pi r(r+\sqrt{h^2+r^2})

\pi 3(3+\sqrt{4.71^2+3^2})

80.90486

<u>total surface area is 80.90486</u>

Can someone please help me please I really need help please help
mr Goodwill [35]

Answer:

  • K'(4, -4)
  • L'(8, -4)
  • M'(8, 8)
  • N'(4, 8)

Step-by-step explanation:

Dilation centered at the origin multiplies every coordinate value by the scale factor.

  K(1, -1) ⇒ K' = 4(1, -1) = (4, -4)

  L(2, -1) ⇒ L' = 4(2, -1) = (8, -4)

  M(2, 2) ⇒ M' = 4(2, 2) = (8, 8)

  N(1, 2) ⇒ N' = 4(1, 2) = (4, 8)

a chord of 12cm long of 8cm is away from the of the circle what is the lenght of the chord which is 6cm away from the centre
lana66690 [7]

Answer:

The length of the chord is 16 cm

Step-by-step explanation:

Mathematically, a line from the center of the circle to a chord divides the chord into 2 equal portions

From the first part of the question, we can get the radius of the circle

The radius form the hypotenuse, the two-portions of the chord (12/2 = 6 cm) and the distance from the center to the chord forms the other side of the triangle

Thus, by Pythagoras’ theorem; the square of the hypotenuse equals the sum of the squares of the two other sides

Thus,

r^2 = 8^2 + 6^2

r^2= 64 + 36

r^2 = 100

r = 10 cm

Now, we want to get a chord length which is 6 cm away from the circle center

let the half-portion that forms the right triangle be c

Using Pythagoras’ theorem;

10^2 = 6^2 + c^2

c^2 = 100-36

c^2 = 64

c = 8

The full

length of the chord is 2 * 8 = 16 cm
