Divide the length of the single top plate by the spacing of the rafters.
12' / 1' = 12
Add one for the end. 12 + 1 = 13

The landscaping uses 8 lbs of fertilizer per day. They are operating 6 days a week, so to find the amount of fertilizer they
use in a week, multiply 8 Ibs/day x 6 days/wk = 48 Ibs/wk. Since the fertilizer is sold in 20 lb containers, Joon needs to buy 3 containers to cover them for a week, even though there may be 12 lbs left over.

The customer has been overcharged by $7.80, so subtract this mistake from the total bill: $37.24-$7.80 = $29.44.

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

To figure out the painter's total service charge, multiply her hourly rate, $35/hr and the number of hours she worked, 6 hours; $35/hrx 6 hours = $210. Take this total and add the cost of the paint $32; $210+$32 = $242.

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

Find out how many rooms Lacey can clean in one hour and add it together with how many rooms Maria can clean in one hour. The total time to clean is 1 hour = 60 minutes.

Lacey can clean 4.29 rooms, 6844 = 4.29.

Maria can clean 3.16 rooms, 684a = 3.16.

When you add their efforts together they can clean 7.45 rooms, but because it asks for complete rooms, you must round down to 7 rooms.

The final calculation is for two houses, so it may be easier to find out how much it costs to clean one house and then double it at the end. One room in the house costs $25 so the additional six rooms will cost $27,6 x $4.50 = $27, so the total for one house is $52, $25 + $27 = $52. We are trying to find the cost for two houses, so by doubling the cost for one house we find the total cost is $104, $52x2 = $104.

Find the area of the four walls. Two of the walls are 15 feet by 8 feet. The other two walls are 12 feet by 8 feet; 15 x 8 = 120 square feet; 12 x 8 = 96 ft2. The total area of the walls in the room is 120 +120 + 96 + 96 = 432 square feet. Next, find the number of gallons of paint that must be purchased. Each gallon covers 300 square feet, so two gallons will be needed. Last, calculate the cost of those two
gallons of paint; 2 x $25.50 = $51.00.

1. Find the lengths and widths of the top of the retention pond:
Multiply the Depth by the Slope
(1.5 x 6 = 9) Since the pond is a rectangle, we now know that on every side of the pond there will be 9’ between the interior and the exterior.
Multiply that length by 2 to gain the full amount to add to the length and width.
(9 x 2 = 18)
Add 18 to the Length and Width of the Bottom dimensions to get the top dimensions.
Top of the Retention Pond:
L = 75 + 18 = 93
W = 40 + 18 = 58
2. Find the average length and width of the retention pond.
Add lengths of the top and bottom together and divide by 2.
75 + 93 = 168/2 = 84
Add the widths of the top and bottom together and divide by 2.
40 + 58 = 98/2 = 493
Calculate the total volume of the soil to be excavated:
V = [(Avg. L x W) x D] / 27
V = [(84 x 49) x 6] / 27
V = (4,116 x 6) / 27
V = 914.67 cu. yds.

To convert inches into feet you must divide by 12 because there are 12 inches for every foot, 274.%2 = 22.9; 22.9 ft.

For the highway portion of the trip. Joe will average 65 mph for 13 miles. Since 13 is 1/5 of 65, this portion of the trip will take Joe 1/5 of an hour, or 12 minutes. For the remaining 12 miles of the trip, Joe will average 24 mph. Since 12 is half of 24, this portion of the trip will take half an hour or 30 minutes. The total time will be 12 minutes + 30 minutes = 42 minutes. To arrive by 1:30 p.m., Joe must leave no later than 12:48 p.m. since 1:30 p.m. - 42 minutes = 12:48 p.m. Therefore, the correct answer is 12:48 p.m.

To find the cost of renting equipment, start with the weekly rate, $45, and add that to the additional cost of the miles traveled. There is a charge of 5 cents per mile, and since we have m miles in this problem, .05m represents the additional charge. Make sure to put 5 cents into dollar form so that all the information is in the same unit, the weekly charge is already in terms of dollars so it is easier to transfer everything into dollars. The total charge is found by adding the parts together 45 +.05m.

To find the total weight, add up the pounds and ounces separately. The sum of the pounds is 5 lbs+7 lbs +14 lbs = 26 lbs. Next, add the ounces from each bin, 6oz + 12oz + 4oz = 22 oz. Since there are 16 oz in 1 lb, 22 oz is equal to 1 lb and 6 oz. Add
this number to the total pounds from the first step; 26 lbs + 1 lb 6 oz = 27 lbs 6 oz.

To find out how many are left, subtract the original amount by the amount that was sold: 37 - 9 = 28.
