Correct answers are:

1)    1/3 (NOT 3/10). .3 repeating is not 3/10, 3/10 is .3.
2)    1/8. To solve, .125 has three places, so use 1000. 1000/125 is 8, that is your denominator. 125/125 is 1 is your numerator.
3)    1/6 (divide 100/16, which is 6 ¼ - round to 6. If you carry this out to 1,000,000/166,667, it is very close to 6.
4)    1/10
5)    2/3 (NOT 3/5)
6)    1/5 (2/10 reduced to 1/5)
7)    3/4 (75/100 reduced)

Ava estimates that 475 songs will fit on her iPad. The actual amount of songs that fit is 350. Find her percent of error.

alukav5142 [94]

Given:

Ava estimates that 475 songs will fit on her iPad.

The actual amount of songs that fit is 350.

To find:

The percent of error.

Solution:

We know that,

$\text{Percent error}=\dfrac{\text{Estimated values - Actual value}}{\text{Actual value}}\times 100$

Putting the given values, we get

$\text{Percent error}=\dfrac{475-350}{350}\times 100$

$\text{Percent error}=\dfrac{125}{350}\times 100$

$\text{Percent error}=\dfrac{250}{7}$

$\text{Percent error}\approx 35.71\%$

Therefore, the percent of error is 35.71%.

Hey there!

Assuming that $"f" = y$

So, let's solve your function, shall we?

$y(-1) = 2 \\ \\ \\ -y= 2 \\ \\ DivideBy(-1) \\ \\ \\ \frac{-y}{1} = \frac{2}{-1} \\ \\ \\ CancelOut: \frac{-y}{1} \\ \\ \\ Keep: \frac{2}{-1} \\ \\ \\ \\ Answer: y = -2 (option D)$

Good luck on your assignment and enjoy your day!

5/8 divided by 3/4 what the answer

charle [14.2K]

Answer:

20/24. Simplified answer is 5/6

Step-by-step explanation:

5/8 divided by 3/4 is the same as asking 5/8 times 4/3

When dividing a number by a fraction, you can always just multiply by the fraction with its numerator and denominator switched!

So, now we have 5/8 times 4/3

Step 1: Multiply the numerators together. 5 times 4 = 20

Step 2: Multiply the denominators together. 8 times 3 = 24

Step 3: Put the new numerator over the new denominator. 20 over 24 is 20/24

Step 4: Simplify the fraction if necessary. 20 and 24 share a common factor of 4, so divide both the numerator and denominator by 4.

20 divided by 4 = 5

24 divided by 4 = 6

So, 20/24 is equal to 5/6.
