Answer:
112°
Step-by-step explanation:
By inscribed angle theorem:
7n - 4 = 31
move -4 to the other side
sign changes from -4 to +4
7n-4+4= 31+4
7n= 31+4
7n= 35
divide both sides by 7 to get n by itself
7n/7= 35/7
cross out 7 and 7 , divide by 7 and then becomes 1*1*n= n
n= 35/7
answer:
n= 5
Answer:
Subtracting Polynomials is very similar to adding polynomials. In fact, we will be changing the subtraction problem to an addition problem.
In the Pre-Algebra section of the website, we started out by reviewing integers.
We said, "When you subtract integers, you must add the opposite. We also talked about the Keep - Change- Change Rule. That rule applies to polynomials as well.
Take a look at these examples that show you how to rewrite the problem as an additional problem.
Step-by-step explanation:
To find this, you'll want to divide the amount of music by the total amount of time. 29/(9+12+29) = 29/50 = 58/100 = 58%
Answer:
The markup amount is $14 and the retail price is $49.
Step-by-step explanation:
You can use the following formula to find the retail price with the information provided:
Retail price=Cost*(100%+markup %)
Cost=35
Markup %= 40%
Now, you can replace the values in the formula:
Retail price=35*(140%)
Retail price=49
Now, you can subtract the cost from the retail price to find the markup amount:
49-35=14
According to this, the answer is that the markup amount is $14 and the retail price is $49.
