Answer:
Step-by-step explanation:
Distance between two points and
is given by the formula,
Distance =
a). A(-6, -4), B(-3, -1)
Distance between A and B =
=
= 3√2
= 4.2 units
b). C(3.5, 1), D(-4, 2.5)
Distance between C and D =
=
= 7.65
≈ 7.7 units
c). Distance between X(5, -5) and Y(-5, 5)
Distance =
=
= 10√2
= 14.14
≈ 14.1 units
Answer:
The quantity of flour need by Colby's recipe is cups.
Step-by-step explanation:
Given: Colby adds cups of flour to his mixing bowl and then realizes he put too much.He takes
cup of flour back out of the bowl.
We have to find the quantity of flour need by Colby's recipe.
The quantity of flour need by Colby's recipe = Number of flour cups Colby added - number of flour cups Colby taken out.
that is,
Number of flour cups Colby added =
Number of flour cups Colby taken out =
The quantity of flour need by Colby's recipe =
taking LCM, we get, LCM(3,4) =12
The quantity of flour need by Colby's recipe =
The quantity of flour need by Colby's recipe =
Thus, The quantity of flour need by Colby's recipe is cups.
