Divide each mile amount by the speed of the current (48/4=12 and 72/4=18) add the two numbers (12+18=30)  The speed of the boat is 30mph

Nina [5.8K]

Answer:

1. 46.125

Step-by-step explanation: Is your second one in the right format? I don't understand what it is asking.  For the first one, however, you need to free the y being multiplied to 8 and so you are going to undo it by dividing 369 by 8.

8, 15, 27, x, 20

common ratio, r= T2÷ T1= T3÷ T2

= 15 ÷ 8 =27÷ 15

24. Anton borrowed $460 for a new bicycle. He made 9 monthly payments to repay the loan. He paid $60 interest. What is his simpl
hodyreva [135]

Answer:

17.4%​

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the interest amount, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time, in year.

In this question:

He borrowed $460, so P = 460

Paid $60 interest, so E = 60

9 months. So t = \frac{9}{12} = 0.75

We have to find I.

E = P*I*t

60 = 460*I*0.75

I = \frac{60}{460*0.75}

I = 0.174

So the correct answer is:

17.4%​

lesantik [10]

Step-by-step explanation:

a1=ar⁰=12 A2=ar¹=-6

a=12 ar=-6

12r=-6

r=-6/12

r=-1/2

a10=ar⁹

=12*(-1/2)⁹

=12*(-512)

=-3/128

S∞ = a1 / (1-r )

=12/(1-1/2)

=12*1/2

=6
