Answer:
25 gallons
Step-by-step explanation:
Let x be the number of gallons of orange juice worth $1.70 per gallon, then x gallons are worth $1.70x.
If 100 gallons of orange juice worth $2.20 per gallon, then 100 gallons are worth
Total cost is
Together we will get x + 100 gallons of a mixture. This mixture we will sell for $2.10 per gallon, so, x + 100 gallons of mixture is worth $2.10(x + 100).
Thus,
Reorder the equations for clarity:
10m + 4m - 3 = 25
Combine like terms, solve.
14m - 3 = 25
14m = 28
m = 2
ANSWER:
Pentagonal prism.
EXPLANATION:
We see that all the sections in the net are rectangles. Also there are 5 of them and a prism has 5 faces.
Answer:
Step-by-step explanation:
standard deviation σ =5000
Mean μ = 36500
X = 30000
Probability that tire fails to reach 30000 miles
P(< 30000) = P( z < (30000-36500) / 5000 )
= P ( z < - 1.3 )
= .0968 ( from z table )
refund per mile = .01
refund for 30000 mile = .01 x 30000 = 300
expected cost of promotion
= 300 x .0968
= 29.04
b )
refund of $50 is equivalent to shortage of milage by 50 / .01 = 5000 miles
Probability of miles less than 30000 - 5000 = 25000
P ( X < 25000 ) = P ( z < (25000 - 36500) / 5000 )
P ( z < - 2.3 )
= 0.0107 Answer .
Answer:
104 miles
Step-by-step explanation:
52/2.5 = 20.8
20.8 miles = 1 inch
20.8 x 5
104 miles = 5 inches
