I need help with this problem what fractions are equivalent to 4.05 repeating
kow [346]

Answer:

401/99 and 802/198

Step-by-step explanation:

Unfortunately the other answer to this question is wrong - you are looking for something equivalent to 4.0505050505050505, not just 4.05.

Typing the answer suggestions into a calculator you get:

405/99 = 4.0909090909 which is incorrect

401/99 = 4.0505050505 which is correct

81/33 = 2.45454545455 which is incorrect

802/198 = 4.0505050505 which is correct

405/100 = 4.05 which is incorrect as it doesn't repeat.

Hopefully this helps, let me know if you have any questions :)

Please help!! If y = sin x, then dy/dx =
Citrus2011 [14]

Answer:

the answer is option B

Step-by-step explanation:

To find dy/dx the equation here is

first multipled by derivative of second + second multipled by derivative of first

y = x*sinx

dy/dx = x * derivative of sinx + sinx * derivative of x

derivative of x with respect to x is 1

derivative of sinx with respect to x is cosx

therefore

dy/dx = x * cosx + sinx * 1

= x * cosx + sinx

Use rounding (to the nearest 10) to estimate the product of 3217 X 44.
Lorico [155]
So using whole number rounding I believe the answer you should get would be 141,550 as 3217 x 44 is equals to 141,548 so the answer may be 141,550 since 50 is the closest ten number to 48, with a distance of only 2 numbers.

You meet with the financial aid office to discuss your costs for attending MGA next semester. Tuition is $113.67 per credit hour
jenyasd209 [6]

Answer:

$1615.05

Step-by-step explanation:

First the cost. We know that tuition per credit hour is 113.67 and there is a flat fee of 660. This can be represented by 113.67h + 660, where h is equal to the number of credit hours.

Next, the amount paid. There are two constants of 350 and 400 already there. We can represent the remaining amount that needs to be paid by another variable, x.

Now, the cost needs to be equal to the amount you pay. We can replace h with 15 for 15 hours and solve for x.

113.67h + 660 = 350 + 400 + x

113.67(15) + 660 = 350 + 400 + x

1705.05 + 660 = 750 + x

2365.05 = 750 + x

1615.05 = x
