Answer:
75 in^2
Step-by-step explanation:
The central vertical rectangle (including "ears") has dimensions
3 in wide by (9+2+2) = 13 in tall
Its area is
A = LW = (3 in)(13 in) = 39 in^2
__
The two rectangles either side of that have dimensions 2 in by 9 in. The area of each of them is
A = LW = (2 in)(9 in) = 18 in^2
__
The total net area is the sum of the areas of the parts:
left rectangle + central rectangle + right rectangle
= 18 in^2 + 39 in^2 + 18 in^2 = 75 in^2 . . . . surface area of the net
Answer:
B
Step-by-step explanation:
A.) If you plug in 5 for t, you'd get -5 squared + 10(5) - 16
Which would equal 25 + 50 - 16 = 59
Answer a says t is less than 5, so for example let's plug in 4. You'd get a lower number, which means its decreasing. A is wrong
B.) Now let's plug in 8 for t.
-8 squared = 64.
64 + 10(8) - 16 = 144 - 16 = 128
Your answer here is positive, and B states is t > 8. Any number above 8 is going to give you a positive number and it is increasing
Answer:
400
Step-by-step explanation:
250 divide by 60 equals 4.16666666667 then you multiply by 96 witch gives you 400
