Hailey's mixing two different coffee blends. Represent them by x and y (in pounds). Then x + y = 5 lb, and x = 5 - y.How much puree Sum. beans are we talking about here?
0.20x +0.80y = 0.60(5 lb) Mult all 3 terms by 100 to get rid of factions:
20x + 80 y = 300. Substitute 5-y for x:
20(5-y) + 80y = 300 => 100-20y + 80y = 300 => 60y = 200, so y = 20/6 or 10/3 lb den x = 5-10/3, or x =5/3 lb
Use 5/3 lb of the first blend and 10/3 lb of the second blend to come up with 5 lb of a 60% blend.
Answer 15
Step-by-step explanation:
21 minus 5 is 16 munus 1 is 15 duh
Answer:
f(8)=4
Step-by-step explanation:
Put the equation in y=mx+b
-3x+12y=24
Add 3x to both sides
12y=3x+24
Divide 12 on both sides
y=3/12x+2
Simplify the fraction
y=1/4x+2
Substitute 8 for x
y=1/4(8)+2
y=2+2
y=4
So, f(8)=4
Hope this helps! :)
Solution
Given data
According to Boyle's law, PV = K
The required general equation thus is
Substituting these values we find that the initial pressure is
The initial pressure to the nearest tenth, therefore, is 1.8 atm.
The final answer, therefore, is Option D
Answer:
A(8)=32cm
B(9)=36cm
C(10)=40cm
Step-by-step explanation:
let 8:9:10=A:B:C
∑ratios=8+9+10=27
