Students have been completing 28 hours of online work over 5 days. This is the average amount of hours the students complete each day.
Round to the nearest whole number if needed.
What is 6 hours.
(28hrs /5 days = 5.6, need to round up)

If you flip a coin 8 times and the coin lands on heads 6 times and tails 2 times. What is the theoretical probability of the coin landing on heads on the 9th flip?
What is Equally likely to be heads or tails
(With Theoretical probability there is always an equal chance of getting the optional outcomes)

This is how you find the volume of a composite figure (Hint: 3 steps)
What is
1* separate the figure into individual shapes
2* find the volume of each individual figure
3* add the volumes of each figure to result in a total volume for the composite shape

This term is defined as the amount of space a 3D object takes up.
What is Volume
(If the question asked about the space of a 2D object: then the Answer would be Area)

True or False
The starting balance in an account was $56 and when the account closed the balance was $392. The closing balance was 700% of the starting balance.
What is True
(700% as a decimal is 7.00, multiply 7 by the original amount: 7 x 56= 392
OR
392/56=7 and 7=700% Move the decimal two places to the right, Remember 1=100%)

A jar contains 2 pink, 6 red, and 4 blue marbles. If one marble is picked without looking, this is the probability that the marble picked will be red or blue? Simplify your answer if needed.
What is to 5/6=0.83 = 83%
(10/12 simplified is 5/6 also 'or' means add in probability)
300
What is 378 cm3
1/2 (bh) x l
1/2 (7x9) x 12
1/2 (63) x 12
31.5 x 12 = 378

This is the amount of outcomes pictured in the tree diagram
What is 8 total outcomes
(The amount of outcomes is the very last branch)

Last week a Xbox at the store was $275, this week the store reduced the price 15%. This is the EXACT current price of the Xbox.
$233.75
(Reduction means the total will be less.
Subtract the percentage from 100: 100% - 15%=85%
Multiply the new percentage by the original total, 275 x 0.85 = 233.75)
400
This is the amount of outfits possible with 5 pairs of jeans, 8 t-shirts, and 2 pairs of shoes

A shopper can either use a 20% off coupon or a $20 off coupon on an item that costs $125. This coupon would offer the most money off.
What is the $20% off coupon
(Any item above $100 should pick the %.
$off: 125 -20= 105
%off: 125 x 0.20 =25; 125-25 =100)

The new iPhone costs $649.00. This is the EXACT cost of the phone with 7% tax.
$694.43
(Tax is in increase,
Add % to 100: 100% + 7%= 107%
Multiply new % by the original amount:
649 x 1.07= 694.43)
