Answer:
Computer disks are $4 each
Notebooks are $3 each
Step-by-step explanation:
For the first equation
<em>$4 x 2 disks = $8</em>
<em>$3 x 3 notebooks = $9</em>
<em>$9 + $8 = </em>$17
For the second equation
<em>$4 x 5 disks = $20</em>
<em>$3 x 4 notebooks = $12</em>
<em>$20 + $12 = </em>$32
Since there are as many of these triangles as the polygon has sides (eight for an octagon), you have to multiply the area of this triangle by the number of sides. You will obtain the total area of the octagon: area of octagon = 8 * base * height / 2 = perimeter * apothem / 2 .
i hope this helped you :)
You times 50 by two so it will become 100 because you multiplied one side by two you have to do it to the other side which will be 90 so 100-90=10
It doesn’t make any difference whether or not the data is grouped, the mean is the same. So b. false.
4/5 of an hour would be 48 minutes. if he still has two thirds to do and it takes 48 minutes to do one third than multiply 48 by 3 and you get your answer: 144 minutes
