Answer:
Step-by-step explanation:
It is given that the snack shop makes 3 mixes of nuts in the following proportions.
Mix I: 6 lbs peanuts, 2 lbs cashews, 2 lbs pecans.
Mix II: 5 lbs peanuts, 3 lbs cashews, 2 lbs pecans.
Mix III: 3 lbs peanuts, 4 lbs cashews, 3 lbs pecans.
they received an order for 25 of mix I, 18 of mix II, and 35 of mix III.
We need to find the matrices A & B for which AB gives the total number of lbs of each nut required to fill the order.
Mix I Mix II Mix III
peanuts 6 5 3
cashews 2 3 4
pecans 2 2 2
The product of both matrices is
Therefore matrix AB gives the total number of lbs of each nut required to fill the order.
Answer:
4%
Step-by-step explanation:
The unemployment rate is calculated by dividing the number of unemployed(2 million) by the labor force (50million) and multiplying the result by 100.
Labor force is the total number of unemployed and employed persons in a country. In this case, we have:
Labor force= No. of unemployed (in million) + No. of full time employed (in million) + No. of part time employed (in million) = 2 + 38 + 10 = 50 million
Unemployment rate= 2/50 × 100 = 4%
Therefore, the rate of unemployment is 4%.
Answer:
1.12 x 10^6 or 1,120,000
Step-by-step explanation:
You work out the first part which would be (3.76 x 10^5) or 376,000.
Then you work out the second part which would be (7.44 x 10^5) or 744,000.
Then you add them together and move the decimal over to where the number is less than ten but greater than 0 so it would be like this:
1.120000
But just cut all the zeros so it would be like this:
1.12
And how ever many times you move the decimal over is the number you put beside the ten by the way. it should look a little like this by the time you are done:
1.12 x 10^6
Answer:
2.86 quarts ( approx )
Step-by-step explanation:
Given,
The initial quantity of the Mr. Gittleboro's radiator that contains 30% antifreeze = 10 quarts,
Let x quarts of pure antifreeze replaced x quarts of Mr. Gittleboro's radiator to bring it up to a required 50% antifreeze,
So, the quantity of 30% antifreeze radiator after drained off x quarts = (10-x) quarts
Also, the quantity of final antifreeze radiator 50% antifreeze = 10 quarts
Thus, we can write,
30% of (10-x) + 100% of x = 50% of 10
30(10-x) + 100x = 500
300 - 30x + 100x = 500
300 + 70x = 500
70x = 200
x = 2.85714285714 quarts ≈ 2.86 quarts
