3x - 18 = 42
3x = 42 + 18
3x = 60
x = 60/3

X^2+y^2=25 find the distance of point (x,y) from origin​
storchak [24]

Answer:

5

Step-by-step explanation:

The radius is 5.

All I do was think of the center-radius form a circle

(x-h)^2+(y-k)^2=r^2

x^2     + y^2    =25

(x-0)^2+(y-0)^2=5^2

The center is (0,0) and the radius is 5.

So a point on the circle (x,y) has a distance of 5 from the center

and the center's case here is (0,0).

Joel sells ice cream cones at the county fair. He has to rent the equipment for $28 and spent $.33 on a gradients for each accou
spin [16.1K]
Rental - $28
Ingredients- $33
Total $61.00

At $1.30 each you can guesstimate he'd have to sell almost 60 cones to break even.
OR
You can divide 1.30 into $61.00 for about 47 cones to break even. (I rounded up)

To make a profit he would either need to sell double that amount or he could raise the cost of his cone to $2.00 & make profit sooner.

Please help me answering this question WILL GIVE BRAINLIEST!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ra1l [238]

The answer you are looking for is 1.

When you divide a fraction by another fraction, you flip the second one (make it the reciplical) and multiply straight across. 1/2 * 2/1 = 2/2, which simplified (divided by 2/2) is 1.

I hope this helps!

Complete the following proof.
Ivan

Using the circle theorems, we have proven that m ∠RTW = 15°

<h3>Circle theorems </h3>

From the question, we are to prove that m ∠RTW = 15°

In the given diagram,

measure of arc ST = 30°

∴ m ∠SRT = 30°

m ∠SRT = ∠T + ∠W ( <em>Exterior angle of a triangle equals the sum of the two remote angles</em>)

Also,

∠T = ∠W (<em>Radii of the same circle</em>)

∴ m ∠SRT = ∠T + ∠T

m ∠SRT = 2 × ∠T

30° = 2 × ∠T

∠T = 30° /2

∠T = 15°

∴ m ∠RTW = 15°  

Hence, we have proven that m ∠RTW = 15°
