Joe borrowed $900 from sam for six months. how much will sam warm if he charges joe a simple interest rate of 4%? a $18 b $216 c $918

B. $216

Step-by-step explanation:

If Sam is charging a simple interest every month for 6 months, he will be charging $36 Dollars a month, or %4 of 900. After 6 Months, Sam will earn $216 from the interest.

So you're basically asked for total interest earning.

simple interest of 4 % means that joe have to pay 4 % interest of 900 in the period of 1 year

since joe only borrowed it for 6 months, you can find it with this formula :

$900 x 6/12 x 4 % =  $ 18

hope this helps

Step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
