This is a very simple question; don't be intimidated. Just see if you can divide both sides of the ratio by the same number and still result in a whole number on both sides. If not, then the ratio is already simplified. It is easy to figure this out by seeing if one or more of the numbers are prime numbers.
Example: 5:10 can be simplified further because both numbers are divisible by 5. 5/5 and 10/5 result in 1 and 2. Therefore, 5:10 can be simplified to be 1:2. However, a number like 9/11 cannot be simplified further, because 11 is a prime number.
Hope this helped you!
Answer:
C. 8
Step-by-step explanation:
I almost thought this was going to be Pythagorean Theorem, but no.
Use Cosine Law:
cos θ = 
θ = cos−1(0.6)
θ = 53.130...
Now use the SOHCAHTOA ratio for sine (
) to find x now that you have one angle:
sin θ = 
x = 10sinθ (θ isn't needed to be written out as it is shown in the equation above)
x = 8
Answer:
1/3
Step-by-step explanation:
There are 6 possible outcomes when rolling 1 die
1,2,3,4,5,6
P ( 1 or 5) = number of times 1 or 5 happens / total outcomes
= 2/ 6
= 1/3
The answer would be A.
Explanation:
If they enter with one car, that’s a price of $3 for the car alone. Because there’s also a fee for each person who enters, and there is a family of 5 who enters, x is representative of the cost for each person who enters. Therefore, there would be 5 x’s and one 3 that when solved would add up to the total of $45 they spent. That would mean A is correct because the equation would be x + x + x + x + x + 3 = 45.
