Answer the following.
Assoli18 [71]

Answer:

40000

Step-by-step explanation:

Simple interest (I) is calculated as

I = \frac{PRT}{100}

P is the amount borrowed , R is the interest and T the time in years

Here I = 2000 , R = 5 and T = 1 with P to be found , then

2000 = \frac{P(5)(1)}{100} ( multiply both sides by 100 )

5P = 200000 ( divide both sides by 5 )

P = 40000

-7+5x=180°

x=180°+7/5

x=37.4°

again

BC=-7+2*37.4

=67.8°

Lemur [1.5K]

Answer:

1/2 is the fractional part of cookie which was eaten by Dan.

Step-by-step explanation:

Dan has 2 1/2 cookies and ate 1/2, so we can just subtract the 2 1/2-1/2

which cancels out the 1/2, which is the fractional part.

He has 2 cookies left.
