Blueberries cost 4.00apound how many blueberries can you get for 13.00$

Answer

3.25 lbs

Step-by-step explanation:

13/4=3.25

Step-by-step explanation:

you have $13 and each pound cost $4, therefore you need to see how many lbs you could get with $13, you divide the amount you have (13) by the amount per pound (4) which would give you how many lbs you would be able to buy. (3.25lbs)

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
