Jamal bought a computer game for $47.75 and a printer cartridge for $28.39. the sales tax on his purchase was 8.5%. he paid with a $100 bill. rounded to the nearest penny, how much change did jamal receive back from the cashier?

$17,39

Step-by-step explanation:

47.75+28.39=76,14

Jamal spend $76,14 but we have to add the 8.5% of sales tax

76.16*0.085=6,4719

Jamal spend 76,14+6,4719=82,61$

if he payed with 100 then he received back from the cashier

100-82,61=17,39$

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)
