Answer:
The correct answer is:
A. 27,465 +52,534 = 79,899
Step-by-step explanation:
Given are the options for addition
We have to check each addition one by one
So,
A. 27,465 +52,534 = 79,899
This option is the example of error of addition by one. The answer should have been 79,999. Hence there is an error in addition ..
Hence, option a: 27,465 +52,534 = 79,899 is the correct answer ..
Answer:
20
Step-by-step explanation:
nPr = n!/(n-r)!
5P2 = 5!/(5-2)!
= 5!/3!
= 5×4×3!/3!
= 5×4
= 20
Answer:
<h2>
64 cm²</h2>
Step-by-step explanation:
given:
the scale from a square park to a drawing of the park is 5 m to 1 cm
the actual park has an area of 1,600 m²
find:
what is the area of the drawing of the park
solution:
drawing scale is 5m : 1cm
<u>1,600 m² </u> = <u> 5² m² </u>
x 1² cm²
cross multiply:
5² m² x = 1600 m² (1 cm²)
x =<u> 1600 m² </u>
5² m²
x = 64 cm²
therefore, the area of a square park in the drawing is 64 cm²
