Answer:
C = 3 √ 5
(since 9 is a perfect square), we can simplify radical 45 to 3 times radical 5
B √ 9*5 is true but not simplified.
We need to find a square numbers that divide into 45
We find 9
And show a * b = c
c= 45
so a * b = 9 * 5 = 3√ 5 is how we arrange this to simplify.
Step-by-step explanation:
The list is
1, 4, 9, 16, 25, 36, 49, 64, 81, 100
We see there are 10 perfect squares 1-100
5 are 1-25
then think 6 , 7, 6 , 9 ,10 squared/ if you cant list them too quickly.
Answer:
Part a) The area of the actual floor is
Part b) The ratio of the area in the drawing to the actual area is
Step-by-step explanation:
we know that
The scale drawing is
step 1
Find the dimensions of the square on a scale drawing
The area of a square is equal to
where
b is the length side of the square
so
step 2
Find the dimensions of the actual floor
Divide the length of the floor on the drawing by the scale drawing
step 3
Find the area of the actual floor
The area of a square is equal to
substitute
step 4
Find the ratio of the area in the drawing to the actual area
Simplify
Divide by 64 both numerator and denominator
