Let, x be the maximum hours he can rent skate board and helmet.
So, total price :
T = 4x + 6x
Now, it is given that he has only $30.
Therefore,
Total price should be less than or equal to $30.
4x + 6x ≤ 30
10x ≤ 30
x ≤ 3
Therefore, the maximum number of hours he can rent the skateboard is 3 hours.
Hence, this is the required solution.
Answer:
x is 7.5 so the answer is D
Step-by-step explanation:
Since the triangles are similar, you can flip the 1st one to match the 2nd.
Now you can write
16/12=10/x
(the 9 is irrelevant)
now cross multiply to solve for x
12x10=120
120/16=7.5
x is 7.5
Answer:
7, 24, 26
Step-by-step explanation:
6 squared is 36 and 8 squared is 64. Add them together and you get 100, which is 10 squared. Do the same for the other ones and you'll notice that 7 squared and 24 squared added together is 625, which is not 26 squared. In my head 25 squared is 625(check if you don't believe me) so I know that the answer is the third one. The basic formula for a right triangle is a^2 + b^2 = c^2, and that's how you find if three numbers form a right triangle or not. Hope this helps :)
Answer:
B. 0.132
Step-by-step explanation:
For each time the dice is thrown, there are only two possible outcomes. Either it lands on a five, or it does not. The probability of a throw landing on a five is independent of other throws. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
Timothy creates a game in which the player rolls 4 dice.
This means that 
The dice can land in 6 numbers, one of which is 5.
This means that 
What is the probability in this game of having exactly two dice or more land on a five?

In which





So the correct answer is:
B. 0.132
The factored form would be (2x + 1)(x^2 - 7)
