She incorrectly multiplied 15 X 1/4
Step-by-step explanation:
Hi,
1) D
Working :
If the bell rings for 2 weeks straight that means it rings for 14 days.
The bell rings 48 times a day (2 * 24).
The answer is then: 48*14 = 672
2) C
Working:
144 cookies * 8 batches = 864 cookies
864 divided into boxes of 8 = 864 / 8 = 108

The first step to do is to calculate first the total
household waste generate for the two years. That is:
total waste generated = 23,400,000 tons + 48,100,000 tons
total waste generated = 71,500,000 tons
Now, to write either a very big number or a very small number
in a form of scientific notation simply means to write it in a decimal form
such as: 12.5 * 10^10
Now to write 71,500,000 in scientific notation, the decimal
form is 7.15, however we still need to find out the * 10^n factor. The value of
n depends on the number of places the decimal point was moved. If the movement
was from right to left, the value of n is positive and if the movement was from
right to left, the value of n is negative. Since the decimal point was moved by
7 places, hence the complete scientific notation is:
7.15 * 10^7 tons
Answer:
1 hour would cost $0.35.
Step-by-step explanation:
Divide 3.5 by 10.
