Henry is mixing concrete. To make concrete he needs to mix cement, sand and gravel in the ratio 1 : 4 : 7 by weight. Henry needs
jolli1 [7]

Answer:

Henry is short of gravel

Step-by-step explanation:

Here, we are to identify which of the ingredients Henry is short of.

To identify this ingredient, what is needed to be done is to share the 180kg of concrete appropriately to get which of the material does not meet its ratio and thus allowing us know which is insufficient.

The total ratio is 1 + 4 + 7 = 12

For cement, we have ;

1/12 * 180 = 15 kg

For sand, we have

4/12 * 180 = 60kg

For gravel, we have

7/12 * 180 = 105 kg

From the values in the question, we can see that all the values we have are greater what is shared in the ratio except in the case of gravel. So we can confidently say he is short of gravel

You have invested $12,000 into two different companies company 1 earns you 6% on your investment each year and Company 2 earns y
vovikov84 [41]

The correct questions says 5% each year for Company 2.

The amount invested in companies A and B are; $10,000 and $2000 respectively.

<h3>Percentages on Investment</h3>

Let the amount in Company 1 be; x

Let the amount in Company 2 be; y

Hence, we have the equation;

  • x + y = 12,000

Additionally, 6% is earned on company 1 and 50% on company 2.

Therefore, we have;

  • 0.06x + 0.05y = 700

  • 6x + 5y = 70000

by solving the equation simultaneously;

  • 6(12000 -y) + 5y = 70000

  • 72000 - 6y + 5y = 70000

  • y = $2000

  • x = $12000 - $2000

  • x = 10000

  • x = $10,000
