Answer:
V= 240 sq cm
A= 268 sq cm
Step-by-step explanation:
V= l * w * h
V= 10 * 8 * 3
V= 240 sq cm
A=2(wl+hl+hw)
A=2(8*10 + 3*10 + 3*8)
A= 268 sq cm
Step-by-step explanation:
30000+2000+600+50+1+0.9+0.07
Concept:
<u>First write ten thousands ,then thousands then hundred,then tens then ones then thenths then hundredths.</u>
The probability of picking a red marble three times in a row with replacement is:
number of red marbles divided by total number of marbles cubed...
(6/10)^3=27/125
The above is the theoretical probability...
From the chart we see that three reds in a row happened twice in twenty-five trials so the experimental probability is:
2/25
The experimental probability about 0.14 less than theoretically expected...
C)
They are compared by there size if thats what your asking.
Answer:
X=5,-2
Steps:
Get everything to the same side:
X^2-3x-10=0
Then factor:
(X-5)(x+2)=0
