A Farmer Was On His Tractor And Drove By Some Chickens And Pigs In His Field He Counted 30 Heads And

Answers

Answer 1

Answer:

There are 18 pigs and 12 chickens.

Step-by-step explanation:

p = # of pigs

c = # of chickens

I'm assuming each animal has one head and all the pigs have 4 legs and all the chickens have 2 legs, therefore:

p+c = 30

4p+2c = 84

Elimination:

-2(p+c = 30)        -2p -2c = -60

4p +2c = 84         4p +2c = 84

                            2p    =     24

                               p    =    12

Now substitute p for 12:

12 + c = 30

c      =    18

Check:

4(12) + 2(18) = 84

48     + 36    = 84

84 = 84

There are 18 chickens and 12 pigs.

The segments in each figure are tangent to the circle at the points shown.
Find each length.

Answers

9514 1404 393

Answer:

  RS = RT = 2

Step-by-step explanation:

The two tangents from a point are the same length.

  RS = RT

  y = y^2/2

  y^2/2 -y = 0

  y(y/2 -1) = 0 . . . . factor out y

Values of y that make these factors zero are ...

  y = 0 . . . . . . . . true if points R, S, T are coincident on the circle

  y/2 -1 = 0   ⇒   y = 2

Then the segment lengths are ...

  RS = RT = 2

i need to find the 9th term of this sequence

Answers

9514 1404 393

Answer:

  26,244

Step-by-step explanation:

The sequence is geometric with a common ratio of -3. The general term is ...

  an = (a1)r^(n-1)

The first term is 4, so we have ...

  an = 4·(-3)^(n-1)

For n=9, we find the 9th term to be ...

  a9 = 4·(-3)^(9-1) = 4·3^8

  a9 = 26,244

Would it be better to have a loan with 5% interest payback in 2 years, or a loan with 2% interest paid back in five years? Explain. Show work to justify your answer.

Answers

Step-by-step explanation:

If the interest on the loan is simple interest. Both the situation will have equal amount of interest ( 5*2 =10% of total amount). Therefore, it would be better to pay back with 2% interest paid back in five years. However, if the interest is compounded annually, 5% in 2 years will have lesser interest than 2% in 5 years. Hence, Former option would be better.

Mike is a cashier. He works 35 hours and is paid a total of £217
What is Mike's hourly rate of pay? (2 marks)
Your answer

Answers

Answer:

Answer vary :

Mike is paid $6.20 per 1 hour.

Step-by-step explanation:

honestly in my opinion that’s the answer.

‘what is happening is we need to find out how much he is paid for only one hour.

knowing that mike is paid 217 in 35 hours we divide

- 217 divided by 35 = 6.2

and that’s the answer to check if it’s right we multiple 6.2 by 35

- 6.2 times 35 = 217

wich shows it is correct.

and that is how I came to that solution.
