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.
Answer: x=20
all angles in the triangle are 180 degree, so:
2x+3x+4x=180
9x=180
divide both sides by 9
x= 20
The answer is: " <span>378 units</span>³ " .
________________________________________________
( 6 units) * ( 9 units) * (7 units) = (6 * 9 * 7) units³ = 378 units³ .

Answer:
Result: 68.68
68.68 is 202% of 34.
Step-by-step explanation:
:
202% × 34 = 68.68
Hope it helps :)
Step 1. Add 72 to both sides
5y = 7 + 5x + 72
Step 2. Simplify 7 + 5x + 72 to 5x + 79
5y = 5x + 79
Step 3. Divide both sides by 5
y = 5x + 79/5
