Answer:
147 in2
Step-by-step explanation:
(Assuming the height is 4 1/2 inches = 4.5 inches)
We need to calculate the area of all six faces of the prism
Two faces have the sides 8 and 3, which area is 8*3 = 24 in2
two other faces have the sides 8 and 4.5, which area is 8*4.5 = 36 in2
the two last faces have the sides 3 and 4.5, which area is 3*4.5 = 13.5 in2
So, summing up all the areas, we have:
24 + 24 + 36 + 36 + 13.5 + 13.5 = 147 in2
Yes because you use the distributive property
Answer : y = f(x) = log4 x
The correct answer is 370. A system of equations can be
used, where h represents the number
of calories in a hamburger and f represents
the number of calories in an order of fries. The equation <span> 2</span> h plus 3 f equals 1,700 represents the
fact that 2 hamburgers and 3 orders of fries contain a total of 1700 calories,
and the equation h<span> equals f
plus 50</span> represents the fact that one hamburger contains 50 more
calories than an order of fries. Substituting f plus 50 for h in
2 h plus 3 f equals 1,700 gives <span>2, parenthesis, f plus
50, close parenthesis, plus 3</span> f, equals 1,700. This equation
can be solved as follows:
2 f plus 100 plus 3 f equals 1,700
5 f plus 100 equals 1,700
5 f equals 1,600
f equals 320
<span>The
number of calories in an order of fries is 320, so the number of calories in a
hamburger is 50 more than 320, or 370.</span>
