Cherie wants to go home in a taxi. she lives 7 miles away. the taxi firm charges $4 plus $1.50 per mile. how much will the fare be?

$14.50

Step-by-step explanation:

Multiply 7 by 1.50. You get 10.5

Add 4 to the total and get 14.50

$14.50

Step-by-step explanation:

The taxi firm charges a fee of $4 before anything, and $1.50 per mile.

We would multiply $1.50 by 7, to get our mileage fee.

7 multiplied by 1.50 equals: 10.5

If we then take the $4 fee and add that we get: $14.50

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.
