Answer:
Step-by-step explanation:
Neither of them has partitioned the values correctly. The answer to the sum 3568 × 39610 =141 328 480.
They tried the partition method but did not partitioned it correctly.
3568 = 3000+500+60+8
39610 = 30000+9000+600+10
Now multiply each value of 3568 with the values of 39610. Like:
3000 * 30000
3000 * 9000
3000 * 600
3000 * 8
and so on....

Answer:
54 and here is why..
Step-by-step explanation:
In order to calculate the surface are of the prims, you have to calculate the area of each face of the prism, also you have to remember the different formulas to calculate the areas:
Rectangle will be (Length x Width) and
Triangle will be (Base x Height / 2)
SOOO, You just have to insert the values into formulas:
Rectangle1 = 4 x 3.5
Rectangle1 = 14
Rectangle 2 = 5 x 3.5
Rectangle 2 = 17.5
Rectangle 3 = 3 x 3.5
Rectangle 3 = 10.5
Triangle 1 = 4 x 3 / 2
Triangle 1 = 6
Triangle 2 = 4 x 3 / 2
Triangle 2 = 6
SOoo again, if you add all the faces, you get the surface area of the prims:
14+17.5+10.5+6+6=54
I hope this help you my friend, have a good day
Answer:
0.069793787 Approximately = 0.07
Step-by-step explanation:
From this question we have total number of keys to be 12,out of these 12, we know that only one key can open the office.
The probability that this 1 key can open the office is 1/12 = 0.083
Going further we have to apply the geometric distribution.
From the question the door opens after the 3rd time. So 2 trials have failed to open this door.
P(X=3) = (1-0.083)²(0.083)
= 0.840889x0.083
= 0.069793787
Approximately
0.07
