Answer:

72

Step-by-step explanation:

The answer is 72 because my teacher gave it to me. I promise i'm legit, and I won't lie. This is the real answer, and if you choose 336, you're probably getting it wrong. That's from Math Olympiad.

Answer:

2.6, 2 3/5, 2 6/10

Step-by-step explanation:

2.6 as a fraction is 2 3/5. When you read the decimal 2.6, it is read as ''2 and 6 tenths. '' This can also be written as a mixed number of 2 6/10.

Answer:

5

Step-by-step explanation:

You want me to let you in on a secret? There's a simple equation that you can use to solve any quadratic problem in a minute or two.

It's the quadratic formula

x =  [tex]x = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}[/tex]

The +- means that you will do this two times, the first time you will do -b + sqrt(b^2-4ac), and the second time you will do minus that.

a is the coefficient of the first term in the expression, b is the second and c is the third.

so we get[tex]x = \frac{-(-10) +- \sqrt{(-10)^2 - 4(1)(24)} }{2(1)}[/tex] , which is the same as

[tex]x = \frac{10 + \sqrt{100 - 24(4)} }{2}[/tex]

and

x = [tex]x = \frac{10 - \sqrt{100 - 24(4)} }{2}[/tex]

The top part simplifies to [tex]\frac{10 + \sqrt{100 - 72} }{2} = \frac{10 + 6}{2} = 5[/tex], which is your answer.

Hey!

So what it's asking for is the slope of the line. You can figure this out by finding two solid points on the line, such as (0,-1) and (4,2).

Knowing that these are two solid points, you can use the Rise/Run method to get the answer. The rise is how many units the slope rises (+) or falls (-) when getting to the next point. The run is how many units to the left or right it goes.

By following this, the slope is 3/4

Given:

Total number of coins (Quarters and dimes) = 60

Total amount = $12.45

To find:

The number of quarters and dimes.

Solution:

Let x be the number of quarters and y be the number of dimes.

We know that,

1 quarter = 0.25 dollar

1 dime = 0.10 dollar

Total coins: [tex]x+y=60[/tex]               ...(i)

Total amount: [tex]0.25x+0.10y=12.45[/tex]             ...(ii)

From (i), we get

[tex]y=60-x[/tex]          ...(iii)

Putting this value in (ii), we get

[tex]0.25x+0.10(60-x)=12.45[/tex]

[tex]0.25x+6-0.10x=12.45[/tex]

[tex]0.25x-0.10x=12.45-6[/tex]

[tex]0.15x=6.45[/tex]

Divide both sides by 0.15.

[tex]x=\dfrac{6.45}{0.15}[/tex]

[tex]x=43[/tex]

Putting x=43 in (iii), we get

[tex]y=60-43[/tex]

[tex]y=17[/tex]

So, the number of quarters is 43 and the number of dimes is 17.

Therefore, the correct option is b.

Answer:

[tex]\frac{31}{12}[/tex] more nuts would be used by Miguel then raisins

Step-by-step explanation:

The computation is shown below:

Nuts used [tex]= 5 \frac{1}{3} = \frac{16}{3}[/tex]

Raisins used [tex]= 2 \frac{3}{4} = \frac{11}{4}[/tex]

Now the difference between them is

[tex]= \frac{16}{3} - \frac{11}{4}\\\\= \frac{64 - 33}{12} \\\\= \frac{31}{12}[/tex]

Hence, [tex]\frac{31}{12}[/tex] more nuts would be used by Miguel then raisins

Answer: if the irrational sum of a plus the square root of b is the root of a polynomial with rational coefficients, then a minus the square root of b, which is also an irrational number, is also a root of that polynomial.

Step-by-step explanation:

sin=opposite/Hypotonouse

80²+60²=hyp²

hyp=100

sinФ=60/100=3/5

Answer:

b. 3/5

Step-by-step explanation:

Using the pythagorean theorem, side AB is 100 m long.

Sine equals opposite over hypotenuse. In this case CB (60) is the opposite and AB (100) is the hypotenuse.

Sine for angle A = 60/100 = 3/5
