x^2y+y^2-30x+221=0 find the radius ​

Answers

Answer 1

Answer:

2

Step-by-step explanation

Let's complete the square. We get:

(x^2-30x)+y^2+221=0

(x^2-30x+225)+y^2+221-225=0

(x-15)^2+y^2-4=0

(x-15)^2+y^2=4

By analyzing this, we see that the radius is just :[tex]\sqrt{4}[/tex]=2

Sandra saves 7% of her salary for retirement. This year her salary was $2,000 more than her salary than in the previous year, and she saved $3,290. What was her salary in the previous year?
complete the equation 0.07( x+____) = 3,290
Sandras salary in the previous year was _____

Answers

9514 1404 393

Answer:

2,000$45,000

Step-by-step explanation:

Where x represents the previous year's salary, its amount this year is said to be ...

  x + 2000

The equation is trying to reflect the fact that 7% of that is $3,290. The missing number is 2000:

  0.07(x +2000) = 3290

__

Solving for x, we find ...

  x = (3290/0.07) -2000 = 45000

Sandra's salary the previous year was $45,000.

A.$111.20
B.$118.71
C.$29.68

Answers

Answer:

About $118.70

Step-by-step explanation:

139 x .2 = 27.8

139 - 27.8 = 111.2

111.2 x .0675 = 7.5

111.2 + 7.5 = 118.7

118.7 = $118.70

If triangle DEF and triangle MNO are two triangles such that DE = MN and EF = No, which of the following would be sufficient to prove the triangles are congruent?

A DE/MN = EF/NO
B DE=DF
C angle D = angle m
D angle E = angle N

Answers

Answer:

The answer is D

angle E=angle N

As N and E are the corresponding angles between those equal sides D. angle E = angle N is sufficient to prove that the triangles are congruent.

What is congruency?

Congruency is geometry that states similarities between two or more figures generally with their respective sides and angles.

We know we can prove that two triangles are congruent by sides and angles.

Given that DEF and MNO are two triangles and side DE = MN and side EF = NO, in which angles N and E lie between those two sides and therefore we can apply SAS( side angle side) congruency to prove that they are congruent.

If you did not learn a different method for unit conversion in a previous class, respond to the following statement.

Explain how to use the unit-factor method to convert 120 pounds to kilograms.
Hint: 1 kilogram=2.2 pounds
To write the unit factors, use the / symbol, like this: 1 gallon/3.79 liters.

Answers

Answer:

120 pounds = 54.5 kilogram

Step-by-step explanation:

We know that,

1 kilogram=2.2 pounds

or

1 pound = (1/2.2) kilogram

We need to convert 120 pounds to kilograms.

[tex]120\ \text{pounds}=\dfrac{120}{2.2}\ \text{kilogram}\\\\=54.5 \text{kilogram}[/tex]

So, there are 54.5 kilograms in 120 pounds.

6/54−x=5/xx

Simplifies to:

−x+1/9=5

Let's solve your equation step-by-step.

−x+1/9=5

Step 1: Subtract 1/9 from both sides.

−x+1/9−1/9=5−1/9

−x=44/9

Step 2: Divide both sides by -1.

−x/−1=44/9/−1

x=−44/9
