Answer:
500 grams is 20 percent of 2.5 kg
Step-by-step explanation:
500*100 = 50,000
50,000/2500=20
Answer:
see below
Step-by-step explanation:
25x + 200 > 1,200
Subtract 200 from each side
25x + 200-200 > 1,200-200
25x> 1000
Divide by 25
25x/25 >1000/25
x>40
The answer is 138 million.
Step 1. Calculate the growth rate.
Step 2. Calculate the population number in 2014.
We will use the formula for exponential growth:
A = P * eⁿˣ
where:
A - the final amount (value)
P - the initial amount (value)
e - the mathematical constant (e ≈ 2.72)
n - the growth rate
x - the time
Step 1:
A = 120 million = 120 000 000
P = 114 million = 114 000 000
n = ?
x = 1997 - 1991 = 6
Therefore:
Logarithm both sides of the equation:
Step 2:
Now when we know the growth rate, it is easy to estimate the population in 2014
A = ?
P = 120 000 000
n = 0.0083
t = 2014 - 1997 = 17
Thus, the population will be 138 million in 2014
69,010 is the total cost of ???
Three ways you can use an electric current:
1. in a battery to power a flashlight or other devices
2. to produce heat
3. using a power tool
4. chargers
