5 0

Answer:

x = ±5

Step-by-step explanation:

x^2-25=0

Add 25 to each side

x^2-25+25=0+25

x^2 = 25

Take the square root of each side

sqrt(x^2) = sqrt(25)

x = ±5

How do I find the arc??
olganol [36]
A circle is 360° all the way around; therefore, if you divide anarc's<span> degree measure by 360°, you find the fraction of the circle's circumference that the </span>arc<span> makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the</span>arc<span>.</span>

Answer:

200 minutes

Step-by-step explanation:

In order to find the range, you have to subtract the greatest number to the lowest number. In this case, 400 is the smallest number, and 600 is the greatest number. 600-400 is 200 minutes.

Phillip bought 12 used CDs and DVDs. CDs cost $2 each, and DVDs cost $3 each. He spent $31, not including tax. How many DVDs did
Ghella [55]
So he bought 12 CDs and DVDs (in total), CDs + DVDs = 12

Each cd is 2 and each cd is 3

Total spent = 31 (2*x + 3*y)

I call x cds and y dvds

x+y = 12

2x+3y = 31

Solve for y

Move x to the right with changed sign

y = 12-x (DVDs, you can also write x = 12-y)

And substitute 12-y in the equation

2x + 3(12-x) = 31

2x + 36 - 3x = 31

2x - 3x = 31 - 36

-x = -5

x = 5 (CDs)

To find DVDs let's rewrite y = 12-x

y = 12-5 = 7 (DVDs)

Have u ever loved someone so much that u would do just about anything 4 them? I feel this way rn. The only problem is it is not
Ne4ueva [31]

Even Though I’m a girl, I undestand how you feel. I mean... I’m bi and i would do anything for my love, when i met her, and i knew i would love her, and she would love me. So many people didnt like us together and many other boys and girls did go after her behind my back, we didnt split becuase she hated everyone who went for her, but, my friend went threw the same thing happening to you. And its not dum, its true love. Falling interest for someone you love. If I wanted something so bad, I would ask for it, ask for there love, or confess. I agree with Treating them before its to late, that is a good statement.

Crazy boy [7]

Answer:

In a state lottery, you must correctly select 5 numbers (in any order) out of 40 to win the top prize.

1. How many ways can 5 numbers be chosen from 40 numbers?

40C5 = \frac{40!}{5!\times35!} = 658008 ways.

2. You purchase one lottery ticket. What is the probability that you will win the top prize?

The answer is 5! ways or 120 ways.

Hence, probability of winning top prize =\frac{120}{658008} =0.0001 or 0.01 %

3. The order of the numbers mattered, will the probability of winning increase or decrease? Why?

The probability decreases.

The probability of winning a game when order matters is always less than the probability of winning a game when order does not matter. This is because the permutation is always greater than the combination.
