Answer:
Step-by-step explanation:
f(x) = -8x + 20
f(-1) = -8* -1 + 20 = 8+20 =28
5 - 2[f(-1)] = 5 - 2*28 = 5 - 56 = -51
Answer:
To reduce the weight by 10 lbs you need to remove two reams of paper, leaving you with 10 reams. The only way to fit these into a cuboid would be 5 stacks of 2, 2 stacks of 5, 1 stack of 10 or 10 stacks of 1. You need to figure out the dimensions of paper arranged like that then work out the surface area. Obviously 1 x 10 or 10 x 1 will be stupid because the box would be awkward to carry, so the correct answer will be whichever of the other two gives you the least surface area (and therefore requires the least packaging). I guess you also need to consider the relative orientations of the stacks - long end to long end or short end to short end.
When filled, what is the weight of the paper in the current-sized box?_____pounds <em>10*5=50 lb
</em>
I might have not answered all parts of the question but I answered the ones I know (lol)
Hope that was helpful.Thank you!!!
Answer:
76.93
Step-by-step explanation:
bc your formula is A=πrsquared so 3.14(π) ×3.5×3.5 bc when it's squared it's the number times itself93
so 3.14×3.5×3.5=38.456
38.456+38.456 because you need the area for both so I added the same number to it or you can multiply by 2 if you want
38.456+38.456=76.93
Answer:
c
Step-by-step explanation:
because I had a test on these
Answer:
Proportional
Step-by-step explanation:
Let's test this out. So for example you have the fractions: 12/30 and 18/?
Let's solve for ?
12 - 18
30 - ?
Solve: 30×18÷12=45
In the problem it also said 45 on the bottom, so yah they are proportional.
