Answer:
C
Step-by-step explanation:
We can notice the expression is the special product a^2 - b^2, which can be factored into (a + b)(a - b). By correlating the expression with the formula, we can say:
a^2 = 9r^2
-and-
b^2 = 100s^2t^2
Therefore:
a = 3r
-and-
b = 10st
Now we can substitute these values into the factored form, (a + b)(a - b):
(3r + 10st)(3r - 10st)
This is the same as option C, meaning C is the answer.

A jar contains 2 red, 5 green, 2 blue and 6 yellow marbles. A marble is chosen at random from the jar. After replacing it, a second marble is chosen. What is the probability of choosing a green and then a yellow marble?
Answer:
Step-by-step explanation:
The probability of picking an item A in a box of N items depends on nA, the amount of items A in the box at the time of picking, with the kinda instinctive value:
p = nA / N
then it means that if you have no green ball, the probability is 0/N = 0, if you only have green balls, it means you have a probability of N/N = 1 = 100%, and if you have as many green balls as non-green balls, you have a probability of nA/(2nA) = 0.5 = 50%.
Here the probability of first picking a green ball (nG=5) in a box of N=3+5+2+6=16 for the 1st pick is:
pG1 = 5/16
Now the trick here is that once you picked the green ball, you put it back in the box before picking another ball. So you still have N=16 balls for the second pick, and the probability of picking a yellow ball (nY=6) for the 2nd pick is:
pY2 = 6/16 = 3/8
(it would have been slightly higher, at 6/15, if you did NOT put back the green marble in the box).
Now you want BOTH events to be true. So you want G1 to be true AND Y2 to be true. The two events are independent (the probability of Y2 is 6/16 if you had G1 but is also 6/16 if you failed G1), so the probability of having both is simply done by multiplicating them:
pG1Y2 = pG1 * pG2 = 15/128
Angel decides to exceed the walking challenge goal. Describe two ways you might adjust the equation or inequality in Part A to represent Angel’s decision to exceed the goal. Give an example and explain.
Answer:
Step-by-step explanation:
The original distance that Angel wanted to walk will be represented as A
Since we don't know the additional distance Angel walked it'll be represented as B
A= the amount of distance Angel wanted to walk
B= the amount of distance Angel wanted to walk past his/her challenge goal
C= the amount of distance Angel walked originally from to past her/his challenge goal
A+B=C
Example:
I decide to work for A hours today as a challenge. Within this time I'm working I decided to extend my goal another B hours.

Answer:
0.18
Step-by-step explanation:
Think of the decimals in the probability column as percentage. So Micheal has a 30% chance of eating the next fry, Lidia would have a 10% chance, so on and so forth.
The percentage will always go up to 100%.
You're given the other people's percentages, but not Ronald.
So in order to find out the answer, add all of the people's numbers, and subtract by one.

Domarina is making bracelets. she needs 62 cm of gold wire for each bracelet. A roll of wire has 3.10 meters. How many bracelets can she make from one roll of wire.
Answer:
5
Step-by-step explanation:
To figure this out you first need to find how many centimeters 3.10 meters is worth. 3.10m=310cm. Then, since each bracelet needs 62 cm, you just do 310/62. 310/62=5 So you can make 5 bracelets with one roll of wire.

Please help, and answer only if you have an answer.
Answer:
$268.38
Step-by-step explanation:
First we will take off the 20% off the 315 dollars. SO we can do this by saying that the discounted price is 80% of the original price, (because 100 - 20 = 80). So 0.8 * 315 = 252. So 252 = discounted price. So then we have to add the tax price.
Sales tax is %6.5, so we can do 252*0.065 to find the tax payed. We get 16.38, so we can dd this to our discounted price to get 252 + 16.38, or $268.38
