A) To find the surface area of a cube, you have to use the formula 6•a^2
meaning you just have to calculate one side and multiply it by six.
541.5 is the surface area of the cube.
B) To find the surface area for just five sides, you'll be doing the same, except instead of 6 it'll be five.
so multiply 9.5 by itself
you get 90.25
Then you multiply 90.5 by 5
You get 451.25
Unfortunately I'm not sure how to do C. good luck
I think that it's E tbh cuz it's that same thing that the question is asking
You would have to subtract 13 from 36 to find the amount of females.
36-13 = 23
there must be 23 females
23:13 is the ratio
Answer:
The graph will have opposite x-intercepts of b and –b and be symmetrical about the y-axis. The graph will have a y-intercept at –b2.
Both problems are proportions, so cross multiply in each problem to get rid of the fractions.
