C = pi×diameter  OR C = 2pi×radius
So...
17.8 = pi×diameter    17.8 = 2pi×radius
17.8/pi = diameter      17.8/2pi = radius
<span>5.66591597407 = diameter or d
</span><span>2.83295798704 = radius or r</span>

Mr mehra spends 30% of his income in food 10% on charity 25% and is left with 15750 what is his salary? find his savings
nalin [4]

Answer:

Mr mehra's salary is 26250

Step-by-step explanation:

suppose,

Mr mehra's salary is x

so,

He spends in food = 30% of x

                               =(30/100) . x      [x%=x/100]

                                = 30x/100

                                =3x/10

He spends in charity =10% of x

                                    =10x/100

                                    =x/10

Money left = 15750

so,

x = 3x/10 + x/10 +  15750

⇒x - 3x/10 - x/10 = 15750

⇒(10x-3x-x) /10 = 15750

⇒6x/10 = 15750

⇒6x=157500

⇒x = 157500/6

⇒x = 26250

∴Mr mehra's salary is 26250

You invest $700 in an account that pays an interest rate of 6.5%, compounded continuously.
Nina [5.8K]
Please include the instructions when you post a question.  Thanks.

Use the formula A = P*e^(rt).

Here, A = $700*e^(0.065*t), where t is the # of years (which you have not yet included in your post).

As an example:  After 2 years you'll have   A = $700*e^(0.065*2), or A=$797.18, in your account.

Answer:

  C.  350 miles

Step-by-step explanation:

Daphne wants to drive 3/4 of the distance in the first 2 days. So, her mileage per day should be about (3/4)/2 = 3/8 of the total mileage:

  (3/8)(932.4 mi) = 349.65 mi ≈ 350 mi

She should drive about 350 miles on each of the first 2 days.
