3 rays have common vertex. All the angles, which are made by neighbor rays( I think they mean adjacent rays), can be:
a)acute
b)obtuse
c)right
d)none of it.

btw I checked answer, but I still didn't understand, so I need explanation.​

Answers

Answer 1

Answer:

[tex]b)\ Obtuse[/tex]

Step-by-step explanation:

[tex]We\ are\ given\ that:\\There\ are\ three\ rays.\\Lets\ mark\ them\ Ray\ OP, OQ,\ and\ OR\ with\ their\ common\ Vertex\ O.\\\\Now,\\We\ know\ that\ the\ sum\ of\ all\ angles\ around\ a\ point[or\ here\ Vertex\ O]\\ should\ be\ equal\ to\ 360.\\Here,\\\\Lets\ consider\ each\ case\ sepearately.\\If\ all\ the\ angles\ formed: \angle POR, \angle ROQ, \angle POQ,\ are\ acute\ then:\\\angle POR, \angle ROQ, \angle POQ<90\\If\ we\ add\ them\ together,[/tex]

[tex]\angle POR+ \angle ROQ+ \angle POQ<90+90+90<270[/tex]

[tex]But\ here\ the\ sum\ of\ the\ angles\ are\ less\ than\ 270,\ but\ the\ sum\ should\\ instead\ be\ 360.\\Hence,\ the\ angles\ formed\ by\ the\ rays\ are\ NOT\ acute.[/tex]

[tex]Similarly,\\If\ all\ the\ angles\ formed: \angle POR, \angle ROQ, \angle POQ,\ are\ right\ then:\\\angle POR, \angle ROQ, \angle POQ =90\\When\ we\ add\ them\ again:\\\angle POR+ \angle ROQ+ \angle POQ=90+90+90=270\\But\ again\ the\ sum\ here\ is\ equal\ to\ 270,\ but\ instead\ the\ sum\ had\ to\\ be\ equal\ to\ 360.\\Hence,\\The\ angles\ formed\ are\ NOT\ right.[/tex]

[tex]Lets\ consider\ the\ Last\ Case,\\If\ the\ angles\ formed: \angle POR, \angle ROQ, \angle POQ\ are\ obtuse,\\\angle POR, \angle ROQ, \angle POQ>90\\When\ we\ add\ them:\\\angle POR+ \angle ROQ+ \angle POQ>(90+90+90)>270\\Here,\\The\ angles\ formed\ are\ greater\ than\ 270.\ As\ 360>270,\ the\ angles\ ARE\\ obtuse.[/tex]

About 527.79

Step-by-step explanation:

formula is A=2πrh+2πr^2

Answer:

[tex]527.52\:\mathrm{in^2}[/tex]

Step-by-step explanation:

The surface area of this cylinder consist of two circles and a 3D outer edge with respect to the circumference. The area of a circle is given as [tex]r^2\pi[/tex]. Using [tex]\pi=3.14[/tex] as requested in the problem, the area of both these circles is:

[tex]2\cdot6^2\cdot 3.14=226.08\:\mathrm{in^2}[/tex].

The area of the outer edge is the circumference of the circle multiplied by the height. The circumference of a circle is given by [tex]2r\pi[/tex].

Therefore, the circumference's 3D outer edge is:

[tex]8\cdot2\cdot6\cdot 3.14 = 301.44\:\mathrm{in^2}[/tex].

Adding these up, the total surface area is:

Option (4)

Step-by-step explanation:

Given equation of the linear graph is,

[tex]y=-\frac{5}{8}x+\frac{2}{3}n[/tex]

By comparing this equation with the slope-intercept form of the linear equation,

y = mx + b

m = [tex]-\frac{5}{8}[/tex]

And b = [tex]\frac{2}{3}n[/tex]

Since, y-intercept 'b' = -12 [given]

[tex]\frac{2}{3}n=-12[/tex]

n = [tex]-12\times \frac{2}{3}[/tex]

n = -8

Therefore, Option (4) will be the answer.

Answers

Answer:

slope= -3,y - intercept y = -2

Step-by-step explanation:

- Make y the subject by taking four on the opposite side of the equal sign.

2y = -6x - 4

- Divide throughout by 2 and from there you get the gradient which is also the slope.

- To get the y - intercept,the value of x =0. Thus you get y =-2.

Ocean water freezes at about -2 1/2 so silly fresh water freezes at zero anti-freeze a liquid used in radiators of cars freeze at -64 imagine if the temperature has dropped to the freezing point for ocean water how many degrees more most the temperature Drop for the anti-freeze to turn solid

Answers

Answer:

Temperature needs to drop by 61.5°

Step-by-step explanation:

Given that:

Freezing temperature of ocean water = - 2.5

Freezing temperature of fresh water = 0

Freezing temperature = anti-freeze = - 64

If temperature has dropped to freezing point for ocean water, then current temperature = - 2.5

How many more degrees must the temperature drop for temperature to turn solid :

Freezing temperature of anti-freeze - current temperature

-64 - (-2.5)

-64 + 2.5

-61.5

-61.5(the temperature needs to drop by 61.5°)

Bradley has ordered a steak from the meat market that weighs 1 5/8 pounds. There is a bone in the steak that weighs 7/8 of a pound. How much does the meat weigh?

Answers

Answer:

3/4

Step-by-step explanation:

the bone and the steak weigh = 1 5/8 pounds

The bone weighs 7/8

The meat weighs = 15/8 - 7/8

Converting 1 5/8 to an improper fraction gives 13/8

13/8 - 7/8 = 6/8 = 3/4

leah makes a guaranteed salary of $200 per week. but is paid commission of 15% of total sales per week. how much would leah make in a week in which she made $225 in sales?how much would leah make in a week if she made x dollars in sales

Answers

Answer:

Total earned with $225 sales = $233.75

Total earned with x sales = 0.15x+200

Step-by-step explanation:

Given that:

Base salary of Leah per week = $200

Commission paid = 15%

Sales made by Leah = $225

Commission = 15% of 225

Commission = [tex]\frac{15}{100} * 225[/tex]

Commission = 0.15 * 225

Commission = $33.75

Total earned = 200 + 33.75 = $233.75

Commission when sales are x

Commission = 0.15x

Total earned = 0.15x+200

Hence,

Total earned with $225 sales = $233.75

Total earned with x sales = 0.15x+200
