Answer:

1.24 ×10²

Step-by-step explanation:

Always keep one digit number (from 1 - 9) behind the decimal.

And add "×10" with the power of how many decimals it took to go from right to left.

124.

12.4 (one)

1.24 (two)

So the power is ².

Answer:

Step-by-step explanation:

Write 124 in scientific notation.

Then, in scientific notation, 124 is written as 1.24 × 102. Actually, converting between "regular" notation and scientific notation is even simpler than I just showed, because all you really need to do is count decimal places.

levacccp [35]

Answer:  1. A. y=17x

2.  $59.50

Step-by-step explanation:

1. In the table , it can be seen that as x increases y increases with the proportionality constant k = \dfrac{y}{x}=\dfrac{51}{3}=\dfrac{85}{5}=\dfrac{119}{7}=17,.

Equation of direct variation between  x and y : y=kx

Put k= 17 , we get

y=17x , which is the required equation.

So correct option is "A".

2. To find : The charge for renting a machine for 3.5 hours.

Put x= 3.5 in above equation , we get

y=17(3.5)=59.5

Hence, the  charge for renting a machine for 3.5 hours is $59.50.

So correct option is "B".
