Answer:729

Step-by-step explanation:X would be 7, so that would make 27^2, and 27^2 is 27x27, because it is 2 27s. Therefore, 27x27 equals 89, drag the 4 above the 2, and multiply the 7 with the top 2, and you mark out the 4 and put 1 over it. The answer for that would Ben 189, put down your denominator, and multiply the second 2 with 7 and the 2 above that 2, and then you get 540, and then you add the 189, 1 over that one, and plus it with 540, which would equal 729. Sorry if I made it sound confusing, I tried. Hope this helps, though!

Surface area = sum of 2 triangles + sum of the 3 rectangles

= 2 * 84 + 18*24 + 18*25 + 18*7 =  1176 ft^2

volume = 1/2*7 *24 * 18  =  1512 ft^3
surface area to volume = 1176:1512 =  0.78 which is less than 1.
so the company wil manufacture it.

G(x)=2x-8, f(x)=5-g(x) what is the value of f(10)
Rudik [331]

By evaluating the function, we conclude that f(10) = -7

<h3>How to evaluate the function f(x)?</h3>

Here we know that:

g(x) = 2x - 8

And f(x) = 5 - g(x).

Then we can write:

f(x) = 5 - (2x - 8) = 5 - 2x + 8 = -2x + 13

Now we want ot evaluate it in x = 10, this means replace the variable by the number 10.

f(10) = -2*10 + 13 = -20 + 13 = -7

Then, we conclude that f(10) = 7

Is 4:5 (4/5) less, or greater than 19:30 (19/30)?
liberstina [14]
4/5 is greater because when you times it by 6 the numerator becomes 24 therefore it is greater
