Hello from MrBillDoesMath!
Answer:
152 in^2
Discussion:
Surface area =
2 (area of side triangle + area of rectangle face) +
area of bottom rectangle
= 2 ( (1/2) 6*4 + 5*8 ) + 8*6
= 2 ( (1/2) 24 + 40 ) + 48
= 2 (12 +40 ) + 48
= 2(52) + 48
= 104 + 48
= 152
Thank you,

Answer:
4x(3a+2b)
Step-by-step explanation:
<span>45.5% is equivalent to 45.5/100. To remove the decimal from the fraction, multiply both by the same factor of ten so they are integers: 455/1000. This can be cancelled down to 91/200 in its simplest form.</span>
Answer: $725
<u>Step-by-step explanation:</u>
Let x represent the amount invested at 8%, then $13,000 - x is the amount invested at 16%.
0.08(x) + 0.16(13,000 - x) = 1500
0.08x + 2080 - 0.16x = 1500
2080 - 0.08x = 1500
- 0.08x = -580
x = 7250
There must be minus sign with 4.9 .
The given equation is the equation of parabola , which is maximum at its vertex, and the formula of vertex is
So the height is maximum at t=2.55 seconds and to find the maximum height , we need to plug 2.55 for t , that is
So the maximum height is 112 m .
