Lakeside Canoe Rentals Hours, x 2 5 7

Charge, y ($) 20 50 70

How much does it cost to rent a canoe for 3.5 hours? Enter the number of your answer only.

(HINT: First make the equation for the table. Then substitute 3.5 for x)

$35

Step-by-step explanation:

it's $10 an hour

equation: y = 10(x)

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

what level of math? also i don't need to be paid if i can you.
