To solve this problem you must apply the proccedure shown below:
1. She has a total of 50 DVDs of 90 minutes each one of them. The cost of each DVD was 11€.
2. Therefore, to calculate the total cost of the collection, you must multiply the cost of each DVD by the total number of them:
€
3. To calculate the total minutes of the collection, you must multiply 90 minutes by the total number of DVDs:
Therefore, the answer is: 550€ and 4500 minutes.
Answer:
Each game cost $14.95.
Step-by-step explanation:
104.65 = 7x
104.65/7 = x
14.95 = x
Answer:
QTS=STQ=STR
Step-by-step explanation:
The answer is c. 46<span>
In a human diploid somatic cell (2n), there are 22 chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes - 22 pairs of autosomes and 1 pair of sex chromosomes. There are in total 46 chromosomes (23 pairs in 2 copies: 23 </span>× 2 = 46<span>).</span>
1) You need to work this problem backwards.
x=0 and x=5 and those are the roots so the factoring must have looked something like this:
(x-0)(x-5) Then you would FOIL it:
x^2-5x-0-0 Then simplify:
x^2-5x.
2) Do the same thing with this problem.
x=7 and x=7
(x-7)(x-7)
x^2-7x-7x+49
x^2-14x+49
I hope that this helps.
