If the machine prints 30 newspapers in 20 minutes, it prints: (30 newspapers)/(20 minutes) = 3/2 newspapers per minute. To calculate the time to print 900 newspapers: (900 newspapers)/(3/2 newspapers per minute) = 1800/3 = 600 minutes ÷ 60 minutes per hour = 10 hours
$3,000/$1,000 = 3. Therefore the yearly amount is: 3 x $34.65 = $103.95 Another method of solving this problem would be: $3,000/x = $1000/$34.65 $1000x = $103.95
To find the volume of the flower box you take l×w×h. Don't forget that the measurements are for a square flower box, so you can assume that if the box is 4-feet long, then it's also 4-feet wide. So 4×4×1=16 cubic feet. Each bag holds 1/2 cubic foot of soil. 16/(1/2) = 16 × 2 = 32.
The pattern is to double each number: 3 + 3 = 6; 6 + 6 = 12; 12 + 12 = 24; so 24 + 24 = 48.
First we must identify the number of seats that were not occupied: Total – occupied = not occupied. 90 – 72 = 18. Then we can work out the percentage: Percentage = (Not Occupied Seats)/(Total Seats) X 100 = 18/90 x 100 = 20%
First set up the equation to determine x. 25% of x = 80 and 25% = 1/4. Similarly 90% = 9/10 Therefore, 1/4x= 80 so, x = (4/1) x 80 = 320 So, 9/10x = 9/10 x 320 = 288
The shop keeper has lost 2 of his original 12 boxes. Therefore, the shopkeeper has 10 boxes left. Each box cost an average of: $90/10 = $9. If the shopkeeper wants a 20% profit he would need to sell each box at: $9 + 20% = $9 + ($9 x 0.2) = $9.00 + $1.80 = $10.80
Solving this question is requires using addition and subtraction. Start with the starting balance, add the deposit, and subtract the expenditures. $928.16+$412.83 =$1,340.99. Now subtract the following from the new balance: $1,340.99- $17.22-$36.59-$67.90=$1,219.28.
If Austin’s hourly wage is x, then Kayte’s wage is (x+3), so Tara’s wage is 2(x+3). Together they earn $41 per hour, so we can write the equation: x+(x+3)+2(x+3)=41 x+x+3+2x+6=41 4x+9=41 4x=32 x=8 Austin’s hourly wage is $8 per hour
There are 7 days a week and 24 hours in a day. Therefore: 7 x 24 = 168
Multiply 113.33 x 6 to get the distance in miles and then double the answer to account for both legs of the trip. 113.33 x 6 ? 680, then 680 x 2 = 1,360 miles.
To work this out we use the following equation: (highest temperature + lowest temperature)/2 = (100+20)/2 = 60 degrees
You may assume the answer is to take the average of the two journeys, which would require adding 50 plus 60 and dividing by 2. However, if a person is going at a slower speed then it takes more hours so the answer will be close to the lower speed. The best way to solve this is to setup a destination length and solve for x, which is the average speed. Assume the destination length is 300 miles. 300/50 = 6 hours and 300/60 = 5 hours. Therefore it takes 11 hours to travel the entire distance of 600 miles. 600/11 = 54.5 miles per hour.
Work this out using algebra with the larger number = x and lower number = y: 2(x-y) = (x+y)/2, 4(x – y) = x + y Sub in y = 9, 4(x – 9) =x + 9, 4x – 36 = x + 9, 3x = 45, x = 15
To calculate the average we must: (Score A + Score B + Score C + Score D)/(number of exams) = (87 + 94 + 89 + 86)/4 =356/4 = 89
