Victoria has a 2 pound package of flour. she uses 2/5 of the flour to make a pizza. she then uses 3/10 of the remaining flour to make bread. find the weight of the package of flour that she has left.

Answer : The weight of the package of flour that she left is, 0.84 pounds.

Step-by-step explanation :

As we are given that the Victoria has a 2 pound package of flour.

First we have to calculate the amount of flour use to make a pizza.

Amount of use to make a pizza =

Now we have to calculate the amount of flour use to make a bread.

She then uses 3/10 of the remaining flour to make bread. That means,

Remaining flour to make bread =

Fraction of flour use to make a bread =

Amount of use to make a bread =

Now we have to calculate the weight of the package of flour that she has left.

Weight of the package of flour that she has left = Total amount of flour - (Sum of flour use to make a pizza and bread)

Weight of the package of flour that she has left = pounds

Weight of the package of flour that she has left = pounds

Weight of the package of flour that she has left = pounds

Weight of the package of flour that she has left = 0.84 pounds

Thus, the weight of the package of flour that she left is, 0.84 pounds.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
