Write the number 0.787 in scientific notation

hi there!

the correct answer to this question is 7.87 x 10 ^ -1

Step-by-step explanation:

first you want to move the decimal to where the number is between 1-10

then you want to count how many places you moved the decimal:

if the number initially started with 0.00 the exponent will be negative and you insert the number you counted

if the number initially was something like 1234.0 then the exponent  will be positive

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
