Answer:

Option B is right.

Step-by-step explanation:

We know that a circle is a locus of points keeping equal distance r from a fixed point called centre.

Here we have centre as (2,1)

Hence equation of the circle is given by

(x-2)^2+(y-1)^2 = r^2

To find r, we can use the fact that (5,2) lies on this circle

Hence (5,2) satisfies this equatin.

So (5-2)^2+(2-1)^2 = r^2

10 = r^2

So equation of the circle is

(x-2)^2+(y-1)^2 = 10

If you currently have $300 set aside for the trip and you're only able to save $75 a week, write an inequality representing how
algol13

Answer:

see the explanation

Step-by-step explanation:

In this problem

I will assume that the total amount required for the trip is $1,200

so

Let

x ----> the number of weeks

we know that

The number of weeks multiplied by $75 plus $300 must be at least $1,200

In this context, the term "at least" means "greater than or equal to"

so

The linear inequality that represent this problem is

75x+300\geq 1,200

Solve for x

subtract 300 both sides

75x\geq 1,200-300

75x\geq 900

Divide by 75 both sides

x\geq 12\ weeks

therefore

The minimum number of weeks you need to save is 12

Eman is planning to sell wind chimes at a craft fair. The cost of her tools for building the wind chimes is 130. The cost of mat
antoniya [11.8K]

We are given : The cost of tools for building wind chimes = $130.

Cost of material for each wind chime = $10.

We need to find the total cost of making 100 wind chimes.

Please note : $130 is the fix cost and $10 is the variable cost of each wind chime.

<em>In order to find the cost of 100 wind chimes, we need to multiply 100 by cost of making one wind chime and add the fix cost for tools for building wind chimes.</em>

Therefore, total cost of making 100 wind chimes = 10×100 + 130

= 1000+130

=1130.

<h3>Therefore, the total cost to make 100 wind chimes is $1130.</h3>

I don’t get this T-chart
Sidana [21]

Yes. It is most likely a proportional relationship.

Divide $55 by 6(hr)

He gets $9.16 an hour, $18.32 for 2 hours, and so on...

Just multiply 9.16 by how many hours you want
