    No offense, but these are pretty simple questions - if you can't answer at least half of them on your own, there is no way that you will be able to get passing grades in University math which is required in your first semester.

    3. HINT: mean means mid-point/average, so what is the mid-point between 10 and 190?

    4. You are correct - the cube weighs 12 lbs

    1. Of the following, which is greater than 1/2? HINT: If the bottom number is more than double the top number, it is less than 1/2. If the bottom number is less than double than the top, then it is greater than 1/2 (I learned this in grade 1 when we did that how to share a pie exercise)

    2. Multiply the seconds: 5, by the number of seconds in a minute, and then multiply the answer by the number of minutes in an hour

    3. You asked this already

    4. You asked this already

    5. Add 41 and 22 and subtract the total from 78. They only put in the part about the 9 students taking both languages to try to fool you.

    6. If you can't answer the other questions, this is way to hard for you because it's actually high school math.

    7 If you can't answer the other questions, this is way to hard for you because it's actually high school math.

    9. Would need to see the picture, but it's only two roads that you would take for each way (the way you describe it).

    I didn't read all of them but the previous answer is incorrect. 4 is A - 48.

    If a cube block weighs 6, then it has a volume of 6. this means its sides are (cubed root of)6.

    On the new cube, if the sides are doubled, then the new volume becomes (2(cubed root of)6)^3 = 48.
