3. although a circle does not have sides, it does have a perimeter. what is the term for the perimeter of a circle? ​

Answers

Answer:

1= Perimeter =9.6

Area = 5.76m^2

Answer:

find the perimeter and area:

1. square with a side 2.4 m in length find the perimeter and area

answer:

length [l]=2.4m

area of square=l²=2.4²=5.76m²

perimeter of square=4l=4×2.4=9.6m

2. rectangle with length (x+3) and width 7

answer:

length [l]=x+3

Breadth [b]=7

perimeter of rectangle =2{l+b}=2(x+3+7)=2x+20

area of rectangle=l×b=(x+3)×7=7x+21

3. although a circle does not have sides, it does have a perimeter. what is the term for the perimeter of a circle.

A phone company offers two monthly plans. Plan A costs $8 plus an additional $0.09 for each minute of calls. plan B cost $16 plus an additional $0.07 for each minute of calls.

a. For what amount of calling do the two plans cost the same? minutes

b. What is the cost when the two plans cost the same? $​

Answers

Answer: 72

Plan A = 30 +0.15x

Plan B = 16 +0.20x

30+0.15x = 16+0.20x

subtract 16 from each side

14 +0.15x = 0.20x

subtract 0.15x from each side

14=0.05x

x = 14/0.05 = 280 minutes

280*0.15 = 42 +30 = $72

280 * 0.20 = 56 +16 = 72

280 minutes and cost $72 each

I need help I don't understand.

Answers

Answer:

arc AB = 90 degrees

x = 9

arc AD = 108 degrees

arc DC = 139 degrees

arc BC = 13 degrees

arc ADC = 247 degrees

Step-by-step explanation:

12x+(17x-14)+(2x+5)+90 = 360

31x+81 = 360

31x = 279

x = 9

arc AD = 12(9) = 108 degrees

arc DC = 17(9)-14 = 139 degrees

arc BC = 2(9)+5 = 23 degrees

arc ADC = 108+139 = 247 degrees

How can you describe the graph of the equation y= mx + b? Explain

Answers

Answer:

mx is the slope. b is the y-intercept

Step-by-step explanation:

the first thing you should always do is identify your slope this is key for graphing. remember your slope is b so what ever b is you locate that point in the x axis.

then whatever your slope is remember that it is rise over run so say your equation is y=3x+5 you plot the point on the y intercept which is 5. now 3x is your slope so you put it as a fraction to make it easier this is what it looks like in a fraction "3/1" so you go up 3 on the graph and over 1 because of rise/run

HELP ASAP 3.) Andy's Karpet Kleaning charges a $23 consultation fee, plus $17 per hour to clean carpets. Stanley
Steemer charges a $37 consultation fee, plus $13 per hour. After how many hours will the total charge be the
same? What is the charge?

Answers

Answer:

After 3.5 hours and the charge is $82.50.

Step-by-step explanation:

Setting up the equations equal to each other will give a solution (x-value) that makes both sides equal (the same price) after the same amount of hours (x-value).

13x + 37 = 17x +23

x = 3.5

Then plug the hours into either side to get the equal price.

13(3.5) + 37 = $82.50

OR

17(3.5) + 23 = $82.50

lines a and b are parallel. if the slope of line a is 1/4 what is the slope of line b?

Answers

1/4

if the lines are parallel the slope is the same!

Answer:

1/4

Step-by-step explanation:

we know that the lines A and B are parallel.

The term "parallel" implies that they will never meet each other, and to do so, the lines must have the same slope.

So the slope of line A is the same as line B (as for all parallel lines have the same slope)

So the slope of line B is also 1/4
