Answer:
9
Step-by-step explanation:
35(a) / 7 = 5
28(b) / 7 = 4
a + b = 35 + 28
35 + 28 = 63
63 / 7
= 9
Hope that helps! :)

Answer:
12.73 Degrees
Step-by-step explanation:
I'm going to assume some things. The height of the truck is not changing, i.e. the distance and length of the ramp are but the height stays the same.
We draw our right triangle, see photo*
We really only care about finding out what side a is so
So, since I stated that height did not change, the same process just using 32 for the hypotenuse.
The key is to find the first term a(1) and the difference d.
in an arithmetic sequence, the nth term is the first term +(n-1)d
the firs three terms: a(1), a(1)+d, a(1)+2d
the next three terms: a(1)+3d, a(1)+4d, a(1)+5d,
a(1) + a(1)+d +a(1)+2d=108
a(1)+3d + a(1)+4d + a(1)+5d=183
subtract the first equation from the second equation: 9d=75, d=75/9=25/3
Plug d=25/3 in the first equation to find a(1): a(1)=83/3
the 11th term is: a(1)+(25/3)(11-1)=83/3 +250/3=111
Please double check my calculation. <span />
