(5×4-4×4)=2
Answer:
p=7
Step-by-step explanation:
pqrs equal to tuv perimeters =60
triangle=20×3
60
Trapezium=(p+8)+12+12+3p
60=4p+32
4p=28
p=7
The surface area, I believe, is 584,064.
Broken down, the formula is really 312 x 312 x 6
312 x 312 = 97,344 97,344 x 6 = 584,064......... There is your answer.
SA = 584,064
Answer:
4
Step-by-step explanation:
Every year, the world grows by 1.1%. Converting to a decimal, we can divide by 100 to get 1.1% = 0.011. This means that the world grows by 0.011 exponentially each year. To put this into an expression, we can add 1 to our percentage to get 1.011. This represents 1 = 100% (the original population) and the growth of 1.1% = 0.011. We multiply the rate including the growth by the population to get the population after one year. After the first year, we have
population * 1.011 as the new population after one year. We do that for every year, so the second year's population is population*(1.011)*(1.011) and so on. If x represents the amount of years, then the population can be represented as
(original population)*1.011ˣ
Therefore, to get from 7 billion to 7.31 billion, we have
7 billion * 1.011ˣ = 7.31 billion
divide both sides by 7 billion to relatively isolate the x
1.011ˣ = 7.31/7
Another way of writing this is
log (base 1.011) (7.31/7) = x
≈ 3.96
Rounding to the nearest whole number, we get 4 as our answer
