Answer:
9) 496 cubic unit
10)10.94
Step-by-step explanation:
in question 9, req volume will be (volume of cube of lenght 10 - that of hole)
hole can be divided into 5 parts,in which 4 have same dimension 6×6×2,and middle part is cube of dimension 6×6×6, total volume will be 4(6×6×2)+6×6×6
=504 cubic.unit
volume of larger cube is 10×10×10=1000 cubic unit
req answer is 1000-504 cubic unit
=496 cubic unit.
10) the ant should walk diagonally to cover minimum distance to reach from A to B, the shortest distance will be when the ant cover the height of lenght 2,then diagonally btwn 4×8, i.e, by using Pythagorean theorem √(16+64)=8.94
now total will be 8.94+2=10.94, it's the shortest possible distance so far!
I'll update each part after solving... wait!
Answer:
(−5)(2)−2(−3)+3

Expression
Step-by-step explanation:
Answer:
greg, 4 seconds
Step-by-step explanation:
find how long it takes each person to run 2km first.
distance/speed:
- pepper: 2/3 *60(seconds)=40 seconds
- Greg: 2/5 *60= 24 seconds
40-12=28 seconds, pepper will take 28 seconds to finish the race from the time greg starts. greg will win by 4 seconds
So they need $125 to start a slime business.
To get money Carrie start to sell cupcakes for 0.50 cents
Juanita will be selling cards for $2.25
Juanita is selling cards for $2.25 and she is selling at least 35 of them
Carrie is selling cupcakes for 0.50 cents and the number of cupvakes is three times the number of cards so we will multiply 35 x 3=105 number of cupcakes
Then we will multiply 0.50 cents x 105= $53.2 on the cupcakes.
After that, we will multiply $2.25 x 35 for the cards = 78.5
Finally add them together
78.5
+53.3
---------
$ 131.8
So they will have $131.8 after selling cupcakes and cards.
