Question

1. Find the rate: 392feet/8 seconds
2. Simplify: 10 lb 28 oz=
3. 12 L = ________ qt
4. Determine the maximum and minimum values of the following set of numbers.
3, -36/7, -1, -2/3, 5/4, -5, 26/9

Answer 1

These are pretty simple questions ... They are VERY straight forward indeed!!

1. Just do what it tells yoiu to do (divide!) and the answer is in feet /s

2 16 oz = 1 lb so 28 oz =?? so 10 lb 28 oz = ??

3. 1 L = ? qt and 12 L = 12 * 1L

4. Maximum = biggest number and minimum = smallest number ... so away you go and numbers get smaller the further they go into the negative range. (Owing $25 means that you have less money than if you are broke ie have no money at all and if you have $2.35 you have more money still)

That should be enough to get you out of trouble BUT I am not doing your homework for you

Answer 2

These problems are about using ratios and reducing fractions.
1. 392 feet per 8 seconds is 392 feet divided by 8 seconds = 49 feet per second.

2. Here you need to know there are 16 ounces in a pound.
28 oz = 1 lb, 12 oz. So 10 lb 28 oz = 11lb 12 oz. You could also express the remainder (12 oz) as a fraction or a decimal. 12 = three fourths of 16, so 12 oz = 3/4 lb, and 11 lb 12 oz = 11 and 3/4 pounds. As a decimal, 3/4 = .75, so 11 lb 12 oz = 11.75 lb.

3. Here you need to know how many quarts are in a liter, so you'll have to look that up. It so happens that google will give you conversions like this if you enter someting like "how many quarts in a liter" and click "Google search." It turns out there are about 1.06 quarts per liter. So you use this ratio to calculate your answer like this:

12 L X (1.06 qt/1 L) = 12.72 qt

4. First simplify sll the fractions:

-36/7=-5.14 or -5 and 1/7, 26/9=2.89 or 2 and 8/9, 5/4=1.25 or 1 and 1/4.
Now, the minimum value is the lowest number, which is -5.14 (-36/7) and the maximum value is the highest number, which is 3.

Answer 3

Here we go MR.
Do me one favor never smoke or do drug in HS. It is not good. say no to peer pressure :


okay 1: distance = rate * Time
from problem 1. The distance is given to be 32 feet and the time also is given to be 8 sec.
Therefore : Rate= distance/Time
= 392/8sec
=
please use your calculator to divide these two numbers the result will be your ans for Rate . The unit is ft/sec . remenber that !


N03) max:26/9,5/4,-2/3,-1,-5,-36/7

Answer 4

1. 49ft/second
2.?
3.12.68 (if the L means liters)
4.?

sorry i don't understand the other two
