First find 10% 10% of $39 = $3.90 so... 30% of $39 = $11.70 This is because 30% is 10% multiplied by 3. So you just have to multiply 3.90 by 3. Then you would work out 1% 1% of $39 = $0.39 so... 3% of $39 = $1.17 This follows the same principle as before. Now you have to add them together to get the discount price. 11.70 + 1.17 = $12.87
To get the price after the discount, simply take the discount price away from the usual price: 39 - 12.87 = $26.13
Therefore the two answers to your questions are.. $12.87 and.. $26.13 Hope this helped :)
Find the area of a parallelogram with base B and height H b = 87 cm
h = 18.6 cm
Answers
area =hb h=18.6 b=87 area=(18.6)(87) a=1618.2 cm^2
The area would be 1618.2 cm. I think I am not positive.
3. Ron used 24 cubes to make this 3-step staircase. If he uses a total of 84 cubes to make a similar staircase, how many steps will the staircase have?
Answers
Divide 24 by 3 to figure out how many cubes are in 1 step (24/3=8). Now divide 84 by 8 to figure out how many steps he built with 84 cubes (84/8=10.5). Ron's second staircase has 10 and a half steps :)
