One quarter of 320 is 80.
Answer:
B
Step-by-step explanation:
A scale model means that the ratios stay the same.
Therefore, Earth's diameter divided by Pluto's diameter is equal to the ratio of Earth's model's diameter divided by Pluto's model's diameter.
We can write this as
8000 / 1500 = 32/ Pluto's model's diameter. Representing Pluto's model's diameter as P, we can say
8000 / 1500 = 32 / P
multiply both sides by 1500 to remove a denominator
8000 = 32 * 1500 / P
multiply both sides by P to remove the other denominator
8000 * P = 32 * 1500
divide both sides by 8000 to isolate the P
P = 32 * 1500/8000
= 6 inches
Multiply 14% and 2000 to get 280.
Therefore, you spent 280 dollars on fresh flowers.
I^2 = -1
-6(3i) = -18i
-18i(-2i) = 36(i^2)
36(i^2) = 36(-1)
36(-1) = -36
i^2 = -1
2(3 - i)(-2 + 4i) :(do foil)
2(-6 + 12i +2i - 4i^2)
-2 (-6 + 14i +4)
-2(-2 + 14i)
4 -28i
4-28i is your answer
hope this helps
