given,
a₂ = 495
a₆ = 311
geometric sequence formula
...................(1)
................(2)
dividing equation (2) by (1)
hence, the common ratio of the geometric sequence is
Answer:
592
Step-by-step explanation:
A=2(wl+hl+hw)
A=2(8*10+12*10+12*8)=592
Answer:
<h2><u><em>
I think 2 + n</em></u></h2>
Step-by-step explanation:
<h2><u><em>
Step1: Distribute parentheses -(-2)-(-n)</em></u></h2><h2><u><em>
Step 2: Then Apply minus - plus rules and u will get -(-a)=a</em></u></h2><h2><u><em>
step 3: = 2+n</em></u></h2>
55 degrees. If you add the other three angles together you get 305. Considering that a circle is 360 degrees, you would subtract those two and get 55.
Answer:
40 in
Step-by-step explanation:
For a width of w, the length is 3w and the area and perimeter are ...
A = LW = (3w)(w) = 3w^2
P = 2(L+W) = 2(3w +w) = 8w
We are given the area, so we can find w to be ...
75 in^2 = 3w^2
25 in^2 = w^2 . . . . . divide by 3
5 in = w . . . . . . . . . square root
Then the perimeter is ...
P = 8w = 8(5 in) = 40 in
