To get the percentage of citizens under 5ft total we use the formula:
(number of citizens who are under 5.5 ft)/(Total population)×100%
number of citizens who are under 5.5 ft=5,500,000
Total population=23,456,900
Hence:
Percentage of population under 5.5 ft tall
=5,500,000/23,456,900×100
=23.45%
Yes, you can simplify this. Find common factors. In this example, there is a 3 in common.
21/120=(7*3)/(3*40)=7/40
40 is not divisible by 7, so this is our final answer.
Hope this helps!
Answer:
(2 x 10 ^-3) x (4 x 10 ^4)=8 x 10 ^1
Step-by-step explanation:
The mass of a single seed can be written as 0.002 =
There are total of 4.3602 * 10 ⁴seeds in the jar
Total mass is the multiplication of these both numbers.
Since we want an estimate, we can use 4 instead of 4.3602 in the 2nd number.
The rule to multiply two numbers in scientific notation is:
So using this formula we multiply the 2 numbers and get answer as follows:
Answer:
x = -10
Step-by-step explanation:
First you have to isolate x
then you have to add 3 on the other side.
so yeahh!!
