Cost per ounce for the 40-ounce peanut butter is
$5.20/40 = $0.13
cost per ounce for the 15-ounce peanut butter is
$2.70 / 15 = $ 0.18
Mia saves 5 cents or $0.05
C is a vertical angle which the vertical side is corresponding to the vertical side of x°.
105°+54°+y°=180°
159°+y°=180°
y°=21°
Meaning, x=21°.
1A=32, 1B=18, 2A=13, 2B=5, 3A=40, 3B=8
So basically the question just wants you to add fractions so we set up the problem like this
1/2+1/5+1/8=weight of herbs=x (x signifies an unknown number)
so
we have to get the bottom numbers the same before we can add them so we
have to find the smallest number that they all can multiply into
so
2=2
5=5
8=2*2*2
so the smallest number that that will go into all three of the numbers is
2*2*2*5 =40
so the bottom number will be 40
so 1/2 is equal to 20/40
1/5=8/40
1/8=5/40
so 20/40+8/40+5/40=33/40
answer is 33/40 grams
so
