an empty tank is filling at 0.2 litres a second given that the volume of the tank is 360000 cm cubed find the length of time it will take for the tank to be full

17.08

correct me if i am wrong.

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

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)
