Answer:
1476 cm²
Step-by-step explanation:
I like to use the formula ...
SA = 2(LW +H(L +W))
= 2((12 cm)(9 cm) + (30 cm)(12 cm +9 cm))
= 2(108 cm² +(30 cm)(21 cm))
= 2(108 cm² +630 cm²) = 2(738 cm²)
total surface area = 1476 cm²
_____
"Lateral surface area" usually refers to the area that is not part of the base(s). For a rectangular prism, it would be the product of the height and the perimeter of the base. You have not designated a base, so we cannot tell if you really want just the lateral surface area or the whole surface area. The above computation figures the whole surface area.
Answer:
The probability that the loan process will take longer than 9 days is 0.6667.
Step-by-step explanation:
The probability that the application takes more than 9 days is given as
Here
x_max=13
x_min=7
x=9 so the value is given as
So the probability that the loan process will take longer than 9 days is 0.6667.
m/_A + m/_B = 90
40 + m/_B = 90
-40. -40
m/_B = 50
Answer:
44
Step-by-step explanation:
He got the right answer, but he kind of did it wrong.
3+x/2=10 simplify both sides of the equation
1/2x+3=10 Subtract 3 from both sides
2*(1/2)=2*7 Multiply both sides by 2
x = 14
