On a backpacking trip through Europe, Ethan bought snacks for 10 Swiss francs. If the foreign exchange rate between the U. S. dollar and Swiss franc is 1:2, how much did Ethan spend in dollars?

A.$5
B. $15
C. $20

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
