Answer:
SA = 2,400 cm²
Step-by-step explanation:
Surface Area (SA) of a cuboid: 2(lw) + 2(wh) + 2(hl)
SA = 2(lw) + 2(wh) + 2(hl)
- l = 20 cm
- w = 20 cm
- h = 20 cm
Substitute the values above and multiply:
SA = 2(lw) + 2(wh) + 2(hl)
SA = 2(20)(20) + 2(20)(20) + 2(20)(20)
SA = 2(400) + 2(400) + 2(400)
SA = 800 + 800 + 800
SA = 2,400 cm²
Final answer: 2,400 cm²

Answer:
0.50
Step-by-step explanation:
The question asks you to apply the classical method of computing probability. In this method, prior events do not interfere in the likelihood of an event happening in the future, instead it states that every possible outcome is equally likely to happen.
In this case there are only two possible outcomes: purchase or not purchase a computer. Therefore, the likelihood that the next customer will purchase a computer is 50% or 0.50.
Answer:
C. 8 bounces
Step-by-step explanation:
To solve this, you can write an equation before turning it into an inequality:
y = 212*(1/2^x)
(x is bounces, y is height)
Now you can change it into an inequality to fit the height of less than 1:
1 > 212*(1/2^x)
In order for the right side of the equation to be less than 1, 2^x must be greater than 212 (because 212*(1/212) is 1, so if the denominator is greater, it'll be less than 1). 2^8 is 256, which is greater than 212, so that means x is 8.
Because x represents bounces, that means the ball's height will be under 1 foot after 8 bounces.
Alfred, because he is more at risk for flipping more than 2 heads, were Eddie can only flip a maximum of 3 so the probability is in his favour
We let
r1 = the original radius of the cylinder
r2 = the new radius of the cylinder
h1 = the original height of the cylinder
h2 = the new height of the cylinder
SA = surface are of the cylinder
the radius and the height are shrunk down to a third of
their value therefore
r2 = r1/3
h2 = h1/3
SA = 2(PI)r^2 +
2(PI)rh
SA = 2(PI)[(r1^2)/9] +2(PI)(r1/3)(h1/3)
Simplifying
SA = [2(PI)r]/9 * (r1 + h1)
