Answer: 9 tilapia

Step-by-step explanation:

The ratio of 6:20 for tilapia to catfish means that for every six tilapia, there are 20 catfish in the pond.

If there are 30 catfish, use direct proportion to find out the number of tilapia:

6     :      20

x     :       30

Cross multiply:

20x = 180

x = 180 / 20

x = 9 tilapia

) a pair of fair dice is rolled. what is the probability that the sum of the top faces is a number 10 or greater?
andrezito [222]
Possible number combinations are 1,1  2,1  3,1  4,1  5,1  6,1  1,2  2,2  3,2  4,2  5,2  6,2  1,3  2,3  3,3  4,3  5,3  6,3  1,4  2,4  3,4  4,4  5,4  6,4  1,5  2,5  3,5  4,5  5,5  6,5  1,6  2,6  3,6  4,6  5,6 and 6,6. of those 36 number combinations the ones that add up to more than 10 include: 4,6  5,5  5,6  6,4  6,5  6,6. thats 6 number combinations. 6/36 of the possible sums of the top faces equal out to 10 or more. 6/36=1/6=0.166666666666666666666666(repeating) and to put that in a percentage, 16.7%
the probability is 16.7%
Hope this helps.

If Javier has a car with a mass of 250,000 kg and it is acted upon with a force of 300 Newtons. What is the acceleration?
natima [27]

Answer:

<u>The acceleration is 0.0012 meters/seconds²</u>

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Mass = 250,000 kg

Force = 300 Newtons

2. What is the acceleration?

Based on Newton's Second Law of Motion, let's recall that:

Force = Mass * Acceleration

Acceleration = Force/Mass

Replacing with the real values, we have:

Acceleration = 300/250,0000

Acceleration = 0.0012 meters/seconds² (we can't express acceleration using Newtons/kilograms as the unit).
