What is the radius of a circle with circumference 17 mm? Round to the nearest tenth. Use 3.14 for TT.

Answers

Answer: 2.7mm

Step-by-step explanation:

The formula for the circumference of a circle is given as 2πr. In thkw case, thw circumference is 17mm.

Therefore, 2πr = 17

2 × 3.14 × r = 17

6.28r = 17

r = 17/6.28

r = 2.7mm

Therefore the radius of the circle is 2.7mm

An exterior angle of a regular polygon is seven times its interior angle.
Find the size of it's interior angle.

Answers

Answer:

22.5°

Step-by-step explanation:

The sum of the interior and exterior angles of a regular polygon is 180°

ext + int = 180°

7 int + int = 180°

8 int = 180° ( divide both sides by 8 )

int = 22.5°

A, B, C, D, E and F are points on a circle. put crosses on the ends of the line that is a diameter of the circle

Answers

9514 1404 393

Answer:

AD is the diameter

Step-by-step explanation:

Angles in a triangle have a sum of 180°, so inscribed angle B is 80° and inscribed angle E is 90°.

An inscribed angle subtends an arc that is twice its measure, so arcs ABD and AED are both 180°. That makes chord AD a diameter.

Points A and D need your cross markings. AD is a diameter of the circle.

The new Bamo Super Ball has a rebound ratio of 0.97. If you dropped the ball from a
height of 125 feet, how high will it bounce on the tenth bounce?

Please help thank you!!

Answers

Answer:

92.18 feet

Step-by-step explanation:

t(n)=125(.97)^x

t(10)=124(.97)^10

Sequence cant have partial or discrete bounce

Answer:

92.18 ft

Step-by-step explanation:

The rebound ratio 0.97 means the ball will rebound 97% of its height on the previous bounce.

Bounce Height

1 125(0.97) = 121.25

2 125(0.97)(0.97) = 117.6125

3 125(0.97)(0.97)(0.97) = 114.084125

See a pattern?

Bounce Height

1 125(0.97)

2 125(0.97)^2

3 125(0.97)^3 the exponent matches the bounce number

Tenth bounce:

10 125(0.97)^10 = 92.18 (rounded to 2 places)

Mathematics Mathematics, 29.12.2020 18:30, lame3245 a grandfather is nine times older than his granddaughter. In 8 years the grandfather will be five times older than his granddaughter how old is each of them now?

Answers

Answer:

Granddaughter = 8

Grandfather = 72

Step-by-step explanation:

Let :

Granddaughter's age = x

Grandfather's age = y

y = 9x

Age in 8 years :

Granddaughter's age = x + 8

Grandfather's age :

y + 8 = 5(x + 8)

y = 9x

Then ;

9x + 8 = 5(x + 8)

9x + 8 = 5x + 40

9x - 5x = 40 - 8

4x = 32

x = 32 / 4

x = 8

y = 9x = 9*8 = 72

Answers

Answer:

5/78 chance to get a Nickel and then a penny without replacing

Step-by-step explanation:

The bag contains a total of 40 coins which show that the probability of getting a Nickel is 5/40 and the probability of getting a penny after taking out a nickel is 20/39. In order to find the Probability of two events together you must multiply the probabilities so

(5/40) * (20/39) = 100/1560 = 5/78

Answer:

Austin will have to buy 180 squares of carpeting.

Step-by-step explanation:

First find the dimension of the room. We do that by multiplying the width times the length and then subtracting the cut out region in the top right. And, in order to know how big that region we cut out is, we have to do a little subtraction.

We know the room is 18' long on the left side and 12' long on the right side. We subtract 12 from 18 to get 6, and we know that the cut out region is 6' long. We do the same thing with the width, 25' wide at the bottom minus 10' wide at the top and we see that the cut out is 15' wide.

18 x 25 = 450

6 x 15 = 90

450 - 90 = 360. The area of the room is 360 [tex]ft^{2}[/tex]

Each piece of carpet is 2' by 1'. So for every 2' long, the piece of carpet is 1' wide. Each carpet piece will cover 2 [tex]ft^{2}[/tex]. Divide 360 by 2 and you get 180.

Answer:

Trust the process

The translation from the pre-image, Parallelogram ABCD, to the image, Parallelogram A'B'C'D' will be; (d) T2, 1(x, y)

How to determine the transformation rule?

Given that the parallelogram ABCD is shifted to the right by 2 units and shifted up by 1 unit to get parallelogram A'B'C'D'

This transformation rule is represented as given;

(x,y) -> (x + 2,y + 1)

This transformation rule can be rewritten

T2, 1(x, y)

Hence, the translation from the pre-image, Parallelogram ABCD, to the image, Parallelogram A'B'C'D' would be;

(d) T2, 1(x, y)

Damian is designing a new board game, and is trying to figure out all the possible
outcomes. How many different possible outcomes are there if he spins a spinner with
5 equal-sized sections labeled Monday, Tuesday, Wednesday, Thursday, Friday, rolls
a fair die in the shape of a pyramid that has four sides labeled 1 to 4, and rolls a fair
die in the shape of a cube that has six sides labeled 1 to 6?

Answers

If he spins a spinner with 5 equal sections they have equally likely probability of 20%
If he rolls a fair die in the shape of pyramid with 4 sides each side has probability of 25%
If he rolls a fair die in the shape of cube with 6 sides each side has probability of 16.7
Total number of outcomes = 5 * 6 * 4 = 120
