What is 9/20 as a decimal and percent?
Answers
Answer: 45%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we want to write 9/20 as a percent, we will need to find a fraction equivalent to 9/20 that has a 100 in the denominator. We can do this by setting up a proportion.
=
Now, we can use cross products to find the missing value.
900 = 20n
÷20 ÷20 ← divide by 20 on both sides
45 = n
Therefore, 9/20 is equal to 45 over 100 or 45%.

Answer: 0.45
Step-by-step explanation: In order to write 9/20 as a decimal, we need to find a fraction equivalent to 9/20 with a 100 in the denominator. Notice that if we multiply both the numerator of 9/20 by 5, we get the equivalent fraction 45/100 which we can now write as a decimal. Remember that the hundredths place is two places to the right of the decimal point. So, we can write 45/100 as 0.45.
Therefore, 9/20 is equivalent to 0.45.
The required, 9/20 as a decimal is 0.45, and as a percentage is 45%.
Decimals and percentages are both ways to express numbers that are less than or equal to 1. Decimals are a way to represent numbers using the base-10 numbering system. Percentages, on the other hand, are a way to express a portion of a whole as a fraction of 100.
To convert 9/20 to a decimal, divide the numerator (9) by the denominator (20).
9 ÷ 20 = 0.45
So, 9/20 as a decimal is 0.45.
To convert 0.45 to a percentage, multiply it by 100.
0.45 x 100 = 45
So, 9/20 as a percentage is 45%.
In summary, 9/20 as a decimal is 0.45, and as a percentage is 45%.

8/5 + 4/1= 8/5 +20/5.
Now you can solve; 8+20= 28. You leave the denominator as 5.
You get 28/5 and now you have to multiply it by 7/1. Another of saying 28/5 is 5 3/5. So 5 3/5 x 7/1= 39 2/10 (final answer)

What is the order of rotational symmetry?
In Mathematics and Geometry, the order of rotational symmetry of any geometrical figure can be defined as the number of times in which the geometrical figure can be rotated around a full (complete) circle and still look the same.
As a general rule in geometry, a geometrical figure with number of sides (n) has "n" lines of symmetry and its order of rotational symmetry is equal to "n."
Based on the above rule, we can reasonably infer and logically deduce that the figure has both line symmetry and point symmetry.

Answer:
292.45 m
Step-by-step explanation:
Both disk are at an angle of 38.48°
From the image below we calculate as,
For disk B, direct distance is 1.296 km from receiver = 1296 m
Vertical height from ground will be = 1296 x sin38.48 = 806.42 m
For disk A, direct distance is 826 m from receiver
Verival height above ground = 826 x sin38.48 = 513.97 m
Difference in height between disks is 806.42 - 513.97 = 292.45 m
