Answer:
78.6km/h
Step-by-step explanation:
<em><u>Speed=distance÷time</u></em>
<u>distance</u>=21km
<u>time</u>=16 minutes<u>(convert into hour by dividing it</u> <u>with 60)</u>
=16÷60=0.267
Speed=21÷0.267=78.65km/h


F(59)=3x-2
f(59)=3(59)-2
f(59)=177-2
f(59)=175

Answer:
x=27
Step-by-step explanation:
Triangle angle =180 degrees
180=2x+5+x+17+3x-4
180=6x+18
(180-18)/6=x
x=27
Answer:
In 17 years time, the initial population of 3400, and growing at a rate of 5% will be ≈ 7792
Step-by-step explanation:
Here we have that the formula for population presented as follows;

Where:
A = Population after growth
P = Original population = 3400
r = 5% = 0.05
t = Time = 17 years
Population growing at a rate of 5% is thus given by the plugging in the above values into the population growth formula thus;

Since we are presenting data relating to number of people, we round alwys down as the statistics should represent the number of whole people on ground.
Therefore, in 17 years time, the initial population of 3400, and growing at a rate of 5% will be ≈ 7792.
