Answer:

C. 6 kg

Step-by-step explanation:

Let m represent the mass of plates on one side of the barbell. Then the total weight of the barbell is ...

2m +24 = 60 . . . . . kilograms

m +12 = 30 . . . . . . . divide by 2

m = 18 . . . . . . . . . . . subtract 12

The mass of plates on one side of the barbell must total 18 kg. If they all have the same mass, then that must be a divisor of 18. In whole numbers, that would include plates of mass 1, 2, 3, 6, 9, 18 kg.

The only one of these on your list of answer choices is ...

6 kg

padilas [110]

Answer:

16% is 4/25 15% is 3/20 14% is 7/50 13% is 13/100 12% is 3/25 11% is 11/100 10% is 1/10 9% is 9/100 8% is 2/25 7% is 7/100 6% is 3/50 5% is 1/20 4% is 1/25 3% is 3/100 2% is 1/50 and 1% is 1/100

Step-by-step explanation:

If you want to find a percent you have to put that number over 100 so say I was looking for 20% you would put 20/100 then you would reduce by dividing if they can and both can be divided by two so it would then be 10/50 then those can be divided by 10 so it would be 1/5

In how many ways can a committee of 5 people be chosen from a total of 30 possible people?
Stolb23 [73]

Answer:  142506

Step-by-step explanation:

Given : The total number of choices for people in committee = 30

The number of people need to be chosen =5

Since , here order doesn't matter, so we use combination.

The combination of r things taking from n at a time is given by :-

C(n,r)=\dfrac{n!}{(n-r)!r!}

Now, the number of possible combinations of 5 people be chosen from a total of 30 possible people :-

C(30,5)=\dfrac{30!}{(30-5)!5!}\\\\=\dfrac{30\times29\times28\times27\times26}{120}\\\\=142506

Hence, the committee can be made in 142506 ways.

What are the degree and leading coefficient of the polynomial of 12u3 -8 + 23u
irga5000 [103]

Answer:

Degree: 3

Leading Coefficient: 12

Step-by-step explanation:

Find the highest power to determine the degree, in this case it's 3. Then identify the term with the highest power (12u^3) to find the leading coefficient.

So, because 3 is the largest and only power in this equation, it is the degree. 12u^3 is the leading term (term containing the highest degree) and 12 is the coefficient attatched to the term. Hope that helped!
