Question

hi can someone plssss check my work to see if its correct

Answer 1

okay I will where is your work

Answer 2

ok thanks ill put it up its geometry

Answer 3

The figure below shows the ideal pattern of movement of a herd of cattle, with the arrows showing the movement of the handler as he moves the herd. The arc the handler makes from the starting point to the return point should be a quarter of a circle:

A sector showing a quarter of a circle is drawn. The radius is marked as 85 feet. The endpoints of the arc of the sector are marked as Starting Point and Return Point. The sector is filled with cattle.

Based on this theory, what distance will the handler move from the starting point to the return point if he creates an arc of a circle of radius 85 feet?

21.25

133.45 feet

66.73 feet

88.97 feet

Answer 4

im going to tell you what i did

Answer 5

ok i did 2(3.14) times 75 then i divided by 4 and got B

Answer 6

okay that is what I got

Answer 7

yay so its correct :) thank you

Answer 8

do you mind checking a fewmore ?

Answer 9

sure

Answer 10

ok thanks ill put it up

Answer 11

Barry is standing in front of a tree at point S. He can see an arc of the tree trunk that stretches from J to K measuring 58°:

The figure shows a circle with points J and K on it and point S outside it. Tangents to the circle at point J and K are drawn from point S. Minor arc JK measures 58 degrees.

What is the measure of angle JSK?

122°

58°

61°

116°

Answer 12

Major arc=58
Major arc=360-58=302
302-58=244/2=122

Answer 13

correct you don't need my help with this but I am still going to chech your work

Answer 14

lol thank you sooo much i have another one tho

Answer 15

(x - 7)2 + (y - 8)2 = 121

Which statement is true?

The circle is centered at (7, 8) and has a diameter of 11.

The circle is centered at (7, 8) and has a radius of 11.

The circle is centered at (-7, -8) and has a radius of 11.

The circle is centered at (-7, -8) and has a diameter of 11.

Answer 16

do you know how to solve this one idk i nedd help pls

Answer 17

okay hold on solving it

Answer 18

B

Answer 19

sorry my computer shut down i lost all of my work :(

Answer 20

im just going to strat on a new one

Answer 21

okay

Answer 22

Using the following equation, find the center and radius of the circle. You must show all work and calculations to receive credit.

x2 + 2x + y2 + 4y = 20

Answer 23

idk how to solve im bad at these

Answer 24

okay I am goingto send you to this site and it is going to explain to you how to solve equations and anything else you need help on okay does that sound good?

Answer 33

A carnival ride is in the shape of a wheel with a radius of 25 feet. The wheel has 20 cars attached to the center of the wheel. What is the central angle, arc length, and area of a sector between any two cars? Round answers to the nearest hundredth if applicable. You must show all work and calculations to receive credit.

Answer 34

ok and ill send u my email

Answer 35

for that site am i supposed to be a teacher

Answer 36

ok... so sector angle 1st

360 in a circle...

25 cars...

360/25 =

the central angle will help to tell you the fraction of the circle you are dealing with

fraction = sector angle
-----------
360


the the arc length = cricumference times fraction

sector area = area of crircle times fraction

angle is

360/20 = 18

so the fraction is

18/360
so arc length = 7.85 ft

area = 98.17 ft^2

Answer 37

no here I will sign up and give you the information

Answer 38

ok thanks pleasssse do

Answer 39

okay sent u a message containing some information for the link that I sent you so use that an look up anything that you need to

Answer 44

Quadrilateral OPQR is inscribed inside a circle as shown below. What equation would be needed to solve for angle Q? What is the measure of angle Q? You must show all work and calculations to receive credit.

Circle N is shown with an incsribed quadrilateral labeled OPQR. O is labeled 2x degrees. P is labeled y degrees. Q is labeled 2x plus 4 degrees. R is labeled 3y plus 8 degrees.anybody know how to do this one ?

Answer 45

O = (2x)
Q = (2x + 4)

O + Q = 180

This gives us the equation:
2x + (2x + 4) = 180

The measure of angle Q is the soulution of that equation.

Answer 46

what is the measure for Q tho u dont get it ?

Answer 47

oh i solve rite?

Answer 48

is it 44?

Answer 49

no that is what I am doing just want ot give you that much

Answer 50

yes it is 44

Answer 51

ohh ok thanks lol ill post the next one and tell u what i got

Answer 52

Using the following equation, find the center and radius of the circle. You must show all work and calculations to receive credit.

x2 + 2x + y2 + 4y = 20

x2 + 2x + y2 + 4y = 20
(x2 + 2x) + (y2 + 4y) = 20

Answer 53

thats what i got so far

Answer 54

this one I don't know how to do that well

Answer 55

ok lol im going to just leave it like that
