Answer:
203 square inches.
Step-by-step explanation:
First you have to find the area of the triangles, and you do so by using the formula A = (B·H)/2, where the a represents area, b represents base, and h represents height. Assuming all of the triangles are the same, you multiply 7 by 11 and then divide by 2 (which equals 38.5) and then multiply that by 4 (which equals 154) and then you have the area of all four triangles combined. Then to find the area of the cube you simply square 7, which results in 49, and then add that to the area of the triangles, which leaves you at 203. 203 square inches is your answer.
A=P(1/2)^(t/h)
P=initial amount
t=time
h=half life
A=final amount
so
A=0.242188 grams
Answer:
A gasoline tank for a certain car is designed to hold 14.0 gal of gas.


a)What is the probability that a randomly selected tank will hold at most 13.7 gal?
We are supposed to find 



Refer the z table for p value
p value = 0.0668
So, 
The probability that a randomly selected tank will hold at most 13.7 gal is 0.0668
b)What is the probability that a randomly selected tank will hold between 13.4 and 14.3 gal?
We are supposed to find 



P(x<13.4)=P(z<-3)= 0.0013



P(x<14.3)= 0.9332

The probability that a randomly selected tank will hold between 13.4 and 14.3 gal is 0.9319
(c) If two such tanks are independently selected, what is the probability that both hold at most 14 gal?
We are supposed to find 



Refer the z table for p value
p value = 0.5
So, 
Two such tanks are independently selected, the probability that both hold at most 14 gal = 0.5 * 0.5 = 0.25
Hence If two such tanks are independently selected, the probability that both hold at most 14 gal is 0.25
