d. If you got your 60% discount and opened up the card for an additional 20%, what is the actual % discount you would receive?
Answer:
The actual discount is a 68% discount.
Step-by-step explanation:
Remember that if something has a price P, and you have a discount of the X%, the new price will be:
P' = P - P*(X%/100%) = P*(1 - X%/100%)
Here we first have a 60% discount, then if the initial price is P, the new price is:
P' = P*(1 - 60%/100%) = P*(1 - 0.6)
Now we have an additional 20% discount (this applies to the new price)
then the final price is:
P'' = P'*(1 - 20%/100%) = P'*(1 - 0.2) = P*(1 - 0.6)*(1 - 0.2)
We want to rewrite this as something like:
P'' = P*(1 - k)
Let's do this:
P'' = P*(1 - 0.6)*(1 - 0.2) = P*(1 - 0.2 - 0.6 + 0.2*0.6)
= P*(1 - 0.8 + 0.12) = P*(1 - 0.68)
And this can be as:
P'' = P*(1 - 68%/100%)
Then the actual discount is a 68% discount.

Answer:
First box: -5, 0, 6, 9
Second box: 10, 12.5
Step-by-step explanation:
4x-12≤24
4x≤24+12
4x≤36
x≤36÷4
x≤9
So the first box would have all the solutions less than or equal to 9:
-5, 0, 6, 9
And the second box would have the solutions greater than 9:
10, 12.5

Write the property that matches the equation.
3+(4+7)=(3+4)+7
Answer:
associative property
Step-by-step explanation:
Answer:
Associative property of addition
Step-by-step explanation:
The associative property states that numbers can be added or multiplied regardless of their paratheses. This means that how the numbers are grouped can change and still be equal. Another example of this would be [tex]2+(6+5)=(2+6)+5[/tex]. In both equations the sides are balanced.

Stuck? Watch a video or use a hint.
Answer:
1.5 cm
Step-by-step explanation:
Interquartile range (IQR) = Q3 - Q1
From the box plot given, the third quartile (Q3) is the data value that falls exactly at the end of the edge of the rectangular box = 7 cm
The first quartile (Q1) is the data value exactly at the beginning of the edge of the box = 5.5 cm
Interquartile range (IQR) = 7 - 5.5 = 1.5 cm

Four members of a relay team evenly split the distance of a race. Each person ran more than 100 meters. Which inequality can be used to represent d, the total distance the group ran?
4 d greater-than 100
4 d less-than 100
StartFraction d Over 4 EndFraction greater-than 100
StartFraction d Over 4 less-than 100
Answer:
The answer would be C.
Step-by-step explanation:
Since each person ran more than 100 meters, the answer would be greater than 100.
d is the total distance the group ran, not the individual distance, so it couldn't be 4d because that would mean it would be 4 times d.
The answer would be d divided by 4. d/4. That is because the total distance divided by 4 would be the individual distance.
