The number of pieces that we could have in 86' if were going to cut it by 14 1/4 long with 1/8 waste for each cut is 5.98 pieces. This is computed by converting first the fractions into decimal, 14.25 and 0.125, then add it together since there is a waste in every cut, 14.375. Then we will divide 86 inches by 14.375 inches.
Answer:
I believe it is C
Step-by-step explanation:
X=amount of canned juice with 25% of orange juice
y=amount of other canned juice with 10% of orange juice.
25%=25/100=1/4
10%=10/100=1/10
17%=17/100
We can suggest this system of equations:
(1) x+y=15
(2) (x/4+y/10) / (x+y)=17/100 ⇒100(x/4 + y/10)=17(x+y) ⇒25x+10y=17x+17y ⇒8x-7y=0
Finally, we have this system of equations:
x+y=15
8x-7y=0
We can solve this system by substitution method.
x+y=15 ⇒ y=15-x
8x-7(15-x)=0
8x-105+7x=0
15x=105
x=105/15
x=7
y=15-x=15-7=8
answer: we should mix 7 liters of juice (with 25% orange juice) and 8 liters of juice (with 10% orange juice).
