The population of a town doubled every 5 years from 1960 to 1975. What is the percentage increase in population in this period ?

777dan777 [17]

Answer:

Step-by-step explanation:

Let p represent the population

in 1965 → the population becomes 2p

in 1970 → the population becomes 2(2p) = 4p

in 1975 → the population becomes 2(4p) = 8p

p ——————> 100%

8p ————-—-> x%

then

$x=\frac{8p*100}{p}=800$

rhombus has sides of length 10 cm. and the angle between two adjacent sides is 76 degrees. Find the lengths of the other diagona

lisabon 2012 [21]

Let the length of one of the diagonals be 2x and the other be 2y, then
cos (76/2) = x/10
x = 10 cos 38 = 7.88 cm

sin (76/2) = y/10
y = 10 sin 38 = 6.16 cm
