Answer:
$42.49
Step-by-step explanation:
s=p−(p×d)
Where:
s
is the sales price: what we are solving for in this problem
p
is the original price: $49.99 for this problem
d
is the discount percent: 15% for this problem. "Percent" or "%" means "out of 100" or "per 100", Therefore 15% can be written as
15/100. Substituting and calculating
s gives: s =$49.99-($49.99×1510)
s=$49.99−$749.8100
s=$49.99−$7.4985 s=$42.4915 s=$42.49
rounded to the nearest cent.
The sales price of the video game is $42.49
For both of them you just make them into fraction.
For #2
and then you simplify it
36. ÷12 3
-----. =. --------
120. ÷12 10
After this you want to change the fraction to a percentage.Percentage are out of 100
so you simply will multiply by 10 to the top and bottom
3. 30
----. * 10 =. -----. = 30%
10. 100
The answer is 30%
For number #3
you simply put 63 over 240
63
-----
240
21
----
80
is that answer because it can't be simplified
after that
Answer:
5
Step-by-step explanation:
use the pythogorean relationship to get the answer.
this type of relationship is used only on right angled triangles.

Answer: You have a better chance if you do not replace the red marble.
Step-by-step explanation:
The bag has:
5 red marbles
8 blue marbles
4 yellow marbles
3 green marbles
A total of 5 + 8 + 4 + 3 = 20
You want to draw a red marble and then a blue marble.
The probability of drawing a red marble in your first attempt is the number of red marbles divided the total number of marbles:
P1 = 5/20
now you want to draw a blue marble.
If you replace the red marble, you have 20 marbles again in the bag, then the probability of drawing a blue marble is:
P2 = 8/20
The joint probability is P = P1*P2 = (5/20)*(8/20) = 0.1
If you do not replace the red marble, you have 19 total marbles in the bag, then the probability of taking a blue marble is:
P2 = 8/19
The joint probability is:
P = P1*P2 = (5/20)*(8/19) = 0.105
The probability is slightly bigger if you do not replace the red marble.
• x+1.793= 2.42
x-1.793= 2.42-1.793 FALSE
• 5.25x = 15.75
Solve for x, by dividing both sides of the equation by 5.25
x = 15.75/5.25
x = 3 TRUE
• The equation x = 2.4 *11.62 can be rewritten as x = 11.62 * 2.4. TRUE
• The solution to the equation x + 9.43 = 16.09 is x = 6.66.
x+9.43 = 16.09
Subtract 9.43 from both sides of the euqation:
x-9.43+9.43= 16.09-9.43
x = 6.66 TRUE
