Answer:
3 boxes
Step-by-step explanation:
First, we find how many cubes are in each box, then we find how many boxes you need for 140 cubes.
<u>To find the number of cubes in a box we need to find the volume of the figure</u>
the top is 2 wide and 4 long so there are 8 cubes on each layer. Sense it is 8 cubes tall with 8 cubes on each layer the model has 8×8=64 cubes in each box.
<u>Now we divide then round up to find how many full boxes she needs to get 140 cubes or more.</u>
If 1 box has 64 cubes and she needs 140 cubes 140/64=2.187. Now we round up sense he can't buy a fraction of a box and the answer is: She needs 3 boxes
1. Add the total ages up and divide that by the number of volunteers, that gives you 130 as the total ages added up and 10 volunteers, which gives you a mean of 13,
2. When the numbers are put in an ascending order 12 and 13 appear to be the middle two, therefore divide the sum of the two to find the median, which is 12.5.
There are 6 time zones in the US: Hawaiian, Alaskan, Pacific, Mountain, Central, and Eastern. To figure out the time in different zones start with what you know: It's 10 am in the Eastern zone, and LA is in Pacific time. Now go back to the list and count backwards from Eastern to Pacific: 3. For each different time zone subtract 1 from 10: 10-3=7. In LA it would be C. 7 am :)
I think it’s a reciprocal function
Step-by-step explanation:
30 1/3 = 91/3
3 × 91/3% = 91/100 (0.91)
(3-0.91=2.09) < I dunno if you need to subtract it tho^^
