Peter’s dog eats 0.3 kilograms of dog food each day. how much dog food will peter’s dog eat in 8 days?

Peter dog ate 2.4 kilograms of dog food in 8 days

Solution:

Given that peters dog eats 0.3 kilograms of dog food each day

To find: amount of dog food eaten by peter dog in 8 days

From given question,

one day = 0.3 kilograms of food

Let "x" be the amount of dog food eaten by peter dog in 8 days

Then for 8 days:

amount of dog food eaten in 8 days = amount of dog food eaten in 1 day x 8

On multiplying we get,

x = 2.4

Thus peter dog ate 2.4 kilograms of dog food in 8 days

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
