ivan bought these two magazines. if the sales tax was 6.75% what was the total amount that he paid for the magazines

Answer:
$10.57
Step-by-step explanation:
Ivan bought these two magazines = $4.95 + $4.95
Total price of two magazines = $9.90
The sale tax was 6.75% of 9.90
= × 9.90
= 0.0675 × 9.90
= 0.66825
Total price of two magazines with sales tax = 9.90 + 0.66825
= 10.56825 ≈ $10.57
The total amount was paid $10.57 for the magazines.

<h2>Answer:</h2><h2>The probability of selecting a defective roll followed by another defective roll = 
</h2>
Step-by-step explanation:
The total number of rolls in a box = 15
The number of defective items = 3
Two rolls are to be selected, one after the other. The probability of selecting a defective roll followed by another defective roll = ?
The probability that the first roll is detective =
The probability that the second roll is detective =
Required probability =
=
So the rate of change can be found in different places.
For the first one:
This equation is in slope-intercept form, or y = mx + b.
m would be the slope/rate of change, and b the y intercept. (x and y would just be any sets of ordered pairs that fit into the equation.)
So if you look at which number is in the m spot, or the rate of change spot, you see that 5 is the rate of change.
For the second one: The formula for slope is:
m =
So just put in any ordered pairs in. I'm just going to put in the ordered pairs, (6, 30) and (4, 22).
Or,
m = (30 - 22) / (6 - 4)
Or,
m = 8/2
Or 4.
For the third one:
You can use the same formula as I stated above.
So you have to look for two ordered pairs here, two points.
So you can estimate that two of the points are: (0, 3) and (-2, -9).
So then just solve for that.
(-9 - 3) / (-2 - 0) = -12 / -2 = 6
For the last one:
Again, use the same equation.
m = (7 - 1) / (-1 - (-3))
m = 6/2
m = 3
So the one with the greatest rate of change would be C.
