Take the total distance and divide it by the length of the board, 24 32 2/16 = 20.125, and then you will need to round up to 21. Twenty ' boards is not enough because it only covers, 20 * 16 = 320,320 linear feet.

To find out how many people are applying for each job, divide the total number of applicants by the total number of positions
available, 65/4 = 16.25, which rounded to the nearest whole number is 16.

Find out what 3.5% of 224,500 is by multiplying the two numbers, remembering to divide the percentage by 100,224,500 x 3.7ioo = 7,857.50.

To calculate the tax, multiply the cost, $30, by the decimal value of the tax, .062, and add that to the original item, $30 x .062 =
$1.86 + $30 = $31.86. You are not just trying to find out the tax, but how much it costs altogether.

This is a problem disguised with confusing information. The 2:5 ratio must be held in a proportion similar to this, where x represents the real height of the house: 2/5 = 10.2/x;2x = 51;x= 25.5

To solve I = E/R for E, multiply both sides of the equation by R. The Rs cancel each other out on the right side of the equation,
so the equation becomes IR = E. The equation can be flipped ’ around to become E = IR, which is Answer A..

There are 12 months in a year and $68.50 is held each month for the government. To find the total for the year, multiply the cost
each month by 12 to represent an entire year: 12 x $68.50 = $822.

1. Calculate the effective length of rebar.
a. 30D indicates to multiply 30 x diameter of the rebar.
Convert the 3/4" fraction to a decimal.
3/4" = 0.75"
30 x 0.75 = 22.5"
b. Convert inches to feet. 22.5" / 12" = 1.875' (loss)
c. Subtract the loss from the length of the bar.
20' - 1.875' = 18.125'
2. Use the formula: Quantity x Length / Effective Length = # Rebars Needed
4 x 440' / 18.125' = 97.1 rebars (Round up to 98)

The invoice weighs 4.2 oz. The first ounce is covered in the initial charge of $.37 and the rest of the 3.2 ounces must be calculated with the additional charge. For postage they round up to the next ounce so the 3.2 ounces rounds up to 4 ounces. An additional 4 ounces will cost $.92, 4 x $.23 = $.92. The total cost is $.37 + $.92 = $1.29.

Since a post is needed for every four feet of fencing, divide the number of feet of fencing, f, by four to find the number of posts needed. The expression is f/4.

The formula for the perimeter of a rectangle is P = I +1 + w + w. Since the two lengths add up to 30, the two widths must add up to 20 to make the perimeter of 50. Since the two widths are the same they must each be 10 feet.

For a customer who only talks 140-155 minutes, Option 1 would only cost $7 per month. Option 2 would cost the same customer between $9.80 and $10.85:
$.07 x 140 = $9.80 and .$07 x 155 = $10.85.

The number of undamaged bricks is 133,145 -12 = 133. To find the percentage available, divide the number of available bricks
by the total number that were sent and multiply by 100 to get a percentage, 133/145 x 100 = 91.7%.

The length of the plot is 60 yards. Convert this to feet by multiplying by 3. The length of the plot is 180 feet. Break this
up into 20 foot sections, since each tree must be 20 feet apart; 180/20 = 9 sections. Make a picture of the plot of land with the trees drawn in to determine the maximum number of trees. There can be a maximum of 8 trees, since each tree must be 20 feet from the edge.

When multiple items are purchased for the same price, simply use multiplication, $48 x 18 = $864.
