Answer: 4,111.7 mm³
Step-by-step explanation:
You need to use this formula to calculate the volume of the square pyramid:
Where "s" is the lenght of any side of the square base and "h" is the height of the pyramid.
Find the height with the Pythagorean Theorem:
Where "a" is the hypotenuse and "b" and "c" are the legs of the right triangle. Let be "c" the height of the pyramid.
You can identify in the figure that:
Then, you can find the height:
Then, knowing that:
You can calculate the volume:
Answer:
2 4/25
Step-by-step explanation:
First, I made the decimal into 2 16/100. Then, keep simplifying the 16/100 until it is fully simplified.
Answer:
0.8
Step-by-step explanation:
Things to remember:
- You can add as many 0's on the end of a decimal and it will still equal the same number, as long as the 0's are on the right side of the decimal point. For example, 0.7 = 0.7000.
- The lowest value has the lowest probability
So, let's rewrite the options with the same amount of decimal points:
1.00
0.90
0.80
0.85
Now, find the value under 0.82. In this option, the lowest value is 0.80, and it is under 0.82, so it is the answer.
<h2>In the year 2000, population will be 3,762,979 approximately. Population will double by the year 2033.</h2>
Step-by-step explanation:
Given that the population grows every year at the same rate( 1.8% ), we can model the population similar to a compound Interest problem.
From 1994, every subsequent year the new population is obtained by multiplying the previous years' population by 
= 
.
So, the population in the year t can be given by 
Population in the year 2000 = 
=
Population in year 2000 = 3,762,979
Let us assume population doubles by year 
.
≈
∴ By 2033, the population doubles.
Answer:
as in the question it is given that 50 people liked both songs 40 liked folk songs and 80 liked none of the song so we can add the number of people
50+40+80
170
Step-by-step explanation:
the people involved in the survey were 170
