Answer:
YES
Step-by-step explanation:
cause 12.6 / 4.5 = 2.8
and 4.2 / 1.5 = 2.8
Easy
so remember
4 aces in a deck
probability =(desired outcomes)/(total possible)
total possible=52
4/52=1st card
then since he picked 1 out the total possible is and assuming he drwe an ace 3/51
so the answer is 4/52 times 3/51=1/221
The first one is not proportional and the second one is proportional
Answer:
Step-by-step explanation:
The given system is
We substitute the bottom equation into the top equation to get:
Expand to get:
Group similar terms:
Combine similar terms:
Put into the bottom equation
The solution is
PART A
Volume = Area of a triangle base x height (..or length)
Volume = 2,400cm^3
Volume = 1/2(16)(h)(20)
2,400cm^3=1/2(16)(h)(20)
2/400cm^3/160 = 160(h)/160
Part A= 15cm^3=height of the box
PART B
Surface Area = 1/2(15*16)(2)+20(17)(2)+16(20)
Surface Area = 240+680+320
Surface Area = 1,240
Part B = You will need approximately 1,240cm of cardboard.
