9.2x10^-8
Move the decimal to the right 8 times. Since it is moved to the right, the exponent is negative.
60 dollars. You multiply 15 four times because 25% of the cost is 15 so you multiply it by 4 to get the total answers.
Answer:5.00 + .60 + .07 that is your answer

Answer:
125.4
Step-by-step explanation:
Given

Required
Round to 1 decimal place
Up till the first decimal place, the number is:

The digit after .3 is 5
The conditions for approximation are:
- If n > 4, approximate to 1
In this case: 5 > 4, so we approximate to 1
Add this "1" to the last digit of 125.3. This becomes 125.4
<em>Hence: when the number is approximated to 1 decimal place, the digit is 125.4</em>
Answer:
270 ft^2
Step-by-step explanation:
find the area of each side
top: 13x7=91
triangle shaped sides(both together): 12x5=60
tiny vertical side: 7x5=35
bottom: 12x7=84
add them all together to get the total surface area is 270ft^2
Hope this helps! :)
