Let "L" represent the population of Linton
and "E" represent the population of Ellmore
12 times E = L
because "Linton is 12 times as great as .. Ellmore"
then E + L = 9646
because "the combined population is 9646"
since L = 12*E
we can plug that into the other equation and get:
E + 12*E = 9646
13*E = 9646 [by adding like terms]
E = 742 [by divided both sides by 13]
so now we have E
we can plug that back into the 1st equation to get L
12*(742) = L
L = 8904
so Population of Linton = 8904
and the Population of Ellmore = 742
(a) 50%
(b) 17%
Explanation:
(a)
No. of seniors = 54 + 46 = 100
Total No. = 66 + 34 + 54 + 46 = 200
% of seniors = 100/200 x 100% = 1/2 x 100% = 50%
(b)
No. of juniors that do not have a job = 34
Total No. = 66 + 34 + 54 + 46 = 200
% of juniors that do not have a job = 34/200 x 100% = 17/100 x 100% = 17%
Answer:
(c) M236
Step-by-step explanation:
56 x 4 = 224
3 x 4 = 12
224+12=236
Answer:
Step-by-step explanation:
Let x be the height ..... then the base = 2x + 2
So we have
Area = (1/2) (base) (height)
20 = (1/2)(2x + 2)(x) simplify
20 = x (x + 1)
20 = x^2 + x subtract 20 from both sides
x^2 + x - 20 = 0 factor
(x + 5) ( x - 4) = 0
Only the second factor makes sense
x - 4 = 0 add 4 to both sides
x = 4 ft and this is the height
And the base = 2(4) + 2 = 10 ft
