Answer:
208 km
16 tablets per day
Step-by-step explanation:
Given:
Length of training track run by Jason = 400 m
Number of times Jason ran on the track = 520
Therefore,
The total length covered by Jason = 520 × 400 = 208,000 m
now,
1 Km = 1000 m
thus,
208,000 m = 
or
= 208 km
b) Amount of calcium carbonate in a tablet = 500 mg = 0.5 g
Maximum amount of calcium carbonate that can be taken = 8 g
hence,
the maximum number of tablets that she can take
= 
= 
= 16 tablets per day
Given that the population of a town today is 33,000 people.
If the population decreases with a constant rate of change and the decrease is 7% in the first year.
The decrease in the population of the town in the first year is given by 0.07 x 33,000 = 2,310
The decrease in the population of the town in 6 years is given by 2,310 x 6 = 13,860
Therefore, in 6 years, the town's population will be 33,000 - 13,860 = 19,140

Answer:
E + F = 2c^2 + 5c + 4
Step-by-step explanation:
E=6c^2-2c-1
F=-4c^2+7c+5
E+F= 6c^2 -2c -1 + -4c^2 + 7c + 5
E + F = 6c^2 - 4c^2 - 2c + 7c - 1 + 5
E + F = 2c^2 + 5c + 4
