Answer:
4,800
Step-by-step explanation:
(14,700- 1,500) / 2 h 45 m
= 13,200 / 2.75
= 4,800 L/h
A. 7+4=11. That’s the answer to the hypotenuse.
Answer:
angle M and N are right angles
we can draw a line joining M and N
so we’d have a triangle MNC AND KMN
both MNC AND KMN BECOME ISOSCELES TRIANGLES
so since we have 55 degrees for angle MKN. We have to find the other 2
180-55=125
now divide by 2 to get 62.5 for each of the remaining sides of triangle KMN
now to find the sides of triangle MNC
90-62.5= 27.5
27.5*2= 55
180-55=125=angle C
(sorry, it’s complex)
Answer: 35%
Step-by-step explanation:
Let the original price be "4x".
60% gain on 1/2 of them will be:
(1.60 × 2x) = 3.2x - 2x = 1.2x
20% gain on (1/4) of them will be:
(1.2 × x) = 1.2x - x= 0.2x
Total gain 1.2x + 0.2x = 1.4x
Total gain percent= Gain/Original price =1.4x/4x = 0.35 = 35%
Answer: 
Step-by-step explanation:
Here, According to the question, The population of the world is 4 billion (approx).
Again According to the question, The world's population has grown at an average rate of 1.9 percent per year since 1945.
Therefore, after 1975 the growth rate will remains same.
Thus, the population of the world after t years,
(By the formula 
)
⇒
Where 1.019 is the growth rate and 4 billion is the initial population.
