no, it's not a square root that we need to identify
Answer:
Refer to the explanation.
Step-by-step explanation:
Let's take each one at a time.
1.
To solve for the complement, we simply subtract our markup rate by 100%.
100% - 30% = 70%
Now to solve for the selling price, we use the formula


Selling Price = $123.91
2.
We do the same process with the first number.
100% - 40% = 60%


SellingPrice = $366.67
3.
The same as the first two.
100% - 20% = 80%


SellingPrice = $111.88
4.
Now to solve for the markup rate, we use the formula:

In this case we first need to find the markup. The markup is the difference between the selling price and the cost.
Selling Price = $235.28
Cost = $199.99
Markup = $235.28 - $199.99
Markup = $35.29
Now the we know our markup, we can then solve for the markup rate using the formula.


MarkupRate = 0.1499 x 100 = 14.99% or 15%
5.
Now for the last one, we need to find for the cost. Let's use the selling price formula to find for the cost.

Selling Price = $30.77
Complement = 65% or 0.65
This will then give us.

We multiple both sides of the equation by 0.65 to leave our cost alone.
30.77 x 0.65 = Cost
Cost = $20
The Dolphins football team gained 16 yards on their first play, then lost 11 yards on the next play. Write an addition expression to represent this situation. Find the sum and explain its meaning.
Answer: On the first play, Dolphin's football team gained 16 yards.
On the 2nd play, Dolphin's football team lost 11 yards.
Therefore, the addition expression to represent this situation is:

The sum of this expression is:

Therefore, we can interpret it as: Dolphin's football team gained 5 yards over the 2 plays
Answer:
StartFraction 42 Over n EndFraction minus 8; when n = 6 the expression equals –1
Step-by-step explanation:
Let's put the equation into numbers:
“8 less than the quotient of 42 and a number”
= 42/n - 8
Now, substitute 6 into this expression:
42/6 - 8
= 7 - 8
= -1
Alright so lets break this down!
What we are looking at is:
y = 3x - 4
the question is
<em>what is the value of x when y = 5?</em>
This means all we have to do is plug in 5 for y and solve for x
y = 5
x = ?
therefore,
5 = 3x - 4
Now some algebra,
5 + 4 = 3x
9 = 3x
9/3 = x
<em>3 = x</em>
Now our concluding statement:
The value of x is 3 when y is equal to 5
Sometimes all you have to do is turn words into numbers and numbers into words!
Good luck! I hope this was helpful.
