So what will it be a percentage of? it will be the percentage of the original recruits, of the original 150.
for this, we need to divide the number of recruits that left over all recruits, and multiply by 100%:
so the number of trainees decreased by 20 %
Answer:
89%
Step-by-step explanation:
500-55=445
445/500=0.89
0.89x100=89
Answer:
x = 35
Step-by-step explanation:
Since they are vertical angles, the angles are congruent and therefore you can set them equal to each other.
4x + 20 = 3x + 55
Have x on one side of the equation by subtracting 3x from both sides.
x + 20 = 55
Subtract 20 from both sides of the equation.
x = 35
Answer:
29,750
Step-by-step explanation:
Each year the population is multiplied by 100% + 4% = 1.04. We want to repeat that multiplication 15 times, once for each of the 15 years. An exponent is what we use to signify (and compute) repeated multiplication. The population will be ...
16,519 × 1.04^15 ≈ 29749.8 ≈ 29,750
