Step-by-step explanation:

there are 6 options that you can get when you roll a dice. 1, 2, 3, 4, 5, 6. if you want to get a 3 or a 5, that means you want 2/6 possible outcomes. 2/6 is 0.333

Find the quotient of 2 3/5 ÷ 1 2/5 Give your answer as a mixed number in its simplest form.

RoseWind [281]

The quotient of 2 3 / 5 ÷ 1 2 / 5 as a mixed fraction is 1 6 / 7

<h3>What is quotient?</h3>

Quotient is the answer obtained when we divide one number by another. Therefore,

2 3 / 5 ÷ 1 2 / 5

let's convert the mixed fraction to improper fractions.

2 3 / 5 = 13 / 5

1 2 / 5 = 7 / 5

Therefore,

13 / 5 ÷ 7 / 5 = 13/ 5 × 5 / 7

13/ 5 × 5 / 7 = 13 / 7 = 1 6 / 7

Therefore, the quotient of 2 3 / 5 ÷ 1 2 / 5 is 1 6 / 7

The owner expects you to hand wash each coffee pot before the coffee shop opens. It takes 10 minutes for all of the coffee pots

tester [92]

Answer:

Total number of coffee pot = 16 pots

Step-by-step explanation:

Given:

Time taken for drying all coffee pot = 10 minutes

Total time taken for cleaning and drying coffee pot = 82 minutes

Time taken for clean a coffer pot = 4 ½ minutes = 4.5 minutes

Find:

Total number of coffee pot

Computation:

Total time taken for cleaning = Total time taken for cleaning and drying coffee pot - Time taken for drying all coffee pot

Total time taken for cleaning = 82 - 10

Total time taken for cleaning = 72 minutes

Total number of coffee pot = Total time taken for cleaning / Time taken for clean a coffer pot

Total number of coffee pot = 72 / 4.5

Total number of coffee pot = 16 pots

25x^-4-99x^-2-4=0 <br> How do I solve for this?

OlgaM077 [116]

Given

$25x^{-4} - 99x^{-2} - 4 = 0$

consider substituting $y=x^{-2}$ to get a proper quadratic equation,

$25y^2 - 99y - 4 = 0$

Solve for $y$ ; we can factorize to get

$(25y + 1) (y - 4) = 0$

$25y+1 = 0 \text{ or } y - 4 = 0$

$y = -\dfrac1{25} \text{ or }y = 4$

Solve for $x$ :

$x^{-2} = -\dfrac1{25} \text{ or }x^{-2} = 4$

The first equation has no real solution, since $x^{-2} = \frac1{x^2} > 0$ for all non-zero $x$ . Proceeding with the second equation, we get

$x^{-2} = 4 \implies x^2 = \dfrac14 \implies x = \pm\sqrt{\dfrac14} = \boxed{\pm \dfrac12}$

If we want to find all complex solutions, we take $i=\sqrt{-1}$ so that the first equation above would have led us to

$x^{-2} = -\dfrac1{25} \implies x^2 = -25 \implies x = \pm\sqrt{-25} = \pm5i$
