Write an inequality to represent this situation.
Answer: x + 30.25 > 50
Step-by-step explanation: X is the amount need to reach 50 dollars or more.
there are n counters in a bag. 4 of the counters are red and the rest are blue. Ross takes a counter from the bag at random and does not replace it. he then takes another counter at random from the bag. the probability Ross takes two blue counters is 1/3. find the value of n
Answer: n = 10.
Step-by-step explanation:
In the bag, we have n counters.
4 of the counters are red.
the rest are blue, then we have:
(n - 4) blue counters.
Now, the probability that Ross takes a blue counter from the bag is equal to the quotient between the number of blue counters (n - 4) and the total number of counters, n
Then the probability is:
p1 = (n - 4)/n
Now he draws another, and it must be blue again, then we can calculate the probability in the same way as above, but he already take a blue counter, so the number of blue counters is (n - 5) and the total number of counters is (n - 1)
The probability of this event is:
p2 = (n - 5)/(n - 1)
The joint probability (the probability that Ross takes two blue counters) is equal to the product of the individual probabilities, and we know that this is equal to 1/3, then we have the equation:
1/3 = ( (n - 4)/n)*((n - 5)/(n - 1))
Now let's solve this for n.
n*(n - 1)/3 = (n - 4)*(n - 5)
(n^2 - n)/3 = n^2 - 4*n - 5*n + 20
n^2 - n = 3*(n^2 - 9*n + 20)
n^2 - n = 3*n^2 - 27*n + 60
0 = (3*n^2 - n^2) - 27*n + n + 60
0 = 2*n^2 - 26*n + 60
The two solutions of this equation can be found with Bhaskara's equation:
[tex]n = \frac{-(-26) +- \sqrt{(-26)^2 - 4*2*60} }{2*2} = \frac{26+- 14}{4}[/tex]
Then the two solutions are:
n = (26 - 14)/4 = 3
This is not an option, because we know for sure that we have 4 red counters, then this option can be discarded.
The other solution is:
n = (26 + 14)/4 = 40/4 = 10
Then we have n = 10, 10 counters in total.

Answer:
Both C and D are similar
Step-by-step explanation:
The are similar because each of the sides are proportional to each other. On letter C the scale factor of each side is 1.2. To get from the first triangle to the second, they multiplied each side by 1.2 and ended up with a slightly larger triangle. The same thing happens on the second one except for it is slightly smaller with a scale factor of 1/2.

You are given the expressions:
3 x (3 + 7) – 42 = 2.
Explain how you will
find the solution
Answer:
22/15=x
Step-by-step explanation:
Well first off we have to do the stuff in the parentheses-
3x(3+7)-42=2
9x+21x-42=2 Now we have to get x by itself
+42 +42
9x+21x=44 Now add the like terms
30x=44 Divide by 30
/30 /30 30 chancels out
44/30 Simplify
22/15=x
Do the parenthesis first, 3+7=10, then do the exponent and get 256,multiply 3 times 10 and get 30, do 256 divided by 2 and get 128, finally do 30-128 to get 98.
98 is your answer
