Answer:
$386.75
Step-by-step explanation:
First we must find the price of the camera after the man sold it, with the 10% loss.
To do this we find 10% of 414, which is 41.4 . Meaning the camera was originally bought from the dealer for $455.40, as we have to add the 10% back onto the price.
Now we find 15% of 455 and subtract it, with 15% being 68.25, the original cost was $386.75. My guy was seriously ripped off :(.
<h2>Orignal price: $386.75</h2>
Step-by-step explanation:
you know how to calculate the area of a rectangle ?
it is length × width.
now the volume of a 3D-rectangle (= a rectangular prism) is simply
length × width × height.
in our case
5 1/2 × 1 1/2 × 2 = 11/2 × 3/2 × 2 = 33/2 =
= 16 1/2 cubic units
Answer:
$37.60
Step-by-step explanation:
If 7 shirts = 32.90 then (32.90/7) x 8 = 37.60
When you factor this quadratic (or any polynomial, for that matter), what you get are the zeros of the function. When the object is on the ground, its height is 0. The zeros of a function are where the graph goes through the x-axis. Where the graph goes through the x-axis, the y value is 0. Using the quadratic formula to factor this gives you zeros of t = -1 and t = 7. The two things in math that will never EVER be negative are time and distance/length, so we know that object will hit the ground 7 seconds after it is thrown.
Which data set has a greater spread? Why? Set A: {38, 12, 23, 48, 55, 16, 18} Set B: {44, 13, 24, 12, 56} has a greater spread b

Answer:
Set B has the greater spread
Step-by-step explanation:
Set B has the greater spread because if you add them all up they you will get a number higher than Set A.
Hope this helped :)
