Answer:
5280people
Step-by-step explanation:
Given parameters:
Percentage increase of population = 25%
Population now = 6600
Unknown:
Population last year = ?
Solution:
Let the population last year = y;
Then;
Percentage of last years population plus the population of last year should give us this year's population;
(
of y) + y = 6600
0.25y + y = 6600
1.25y = 6600
y = 
= 5280people
Last year, there was 5280people in the locality.

Answer:
(c) BK = 65
Step-by-step explanation:
Corresponding sides are proportional in similar triangles, so ...
ZT/ZQ = KF/KB
27/(2x +7) = 45/(4x+1)
27(4x+1) = 45(2x +7) . . . cross-multiply
3(4x +1) = 5(2x +7) . . . . divide by 9
12x +3 = 10x +35 . . . . . eliminate parentheses
2x = 32 . . . . . . . . . . . . . subtract 10x+3
x = 16 . . . . . divide by 2
Then the length of BK is ...
BK = 4x+1 = 4·16 +1
BK = 65
Answer:
8 hours
Step-by-step explanation:
6x+20=68
subtract 20 from both sides
6x=48
divide 6 both sides
x=8
