Answer:
If the number of blue tiles in the bag is 180, then the probability of randomly drawing a red tile equal to 1/10.
Step-by-step explanation:
Total number of red tiles in a bag = 20
Let us assume the number of blue tiles in a bag = p
So, the total number of tiles in a bag = Red Tiles + Blue tiles
= 20 + p
Now, let us find the probability of drawing a red tile:

But, here the probability of drawing a red tile = 1/10

or, p = 180
Hence, if the number of blue tiles in the bag = 180, then the P Picking out a red tile ) is 1/10.
6 divided by some number.
Answer:
Yes
Step-by-step explanation:
1/1=1
So 11/11 =1
By substituting 11 for h you get it fits
110 = 11 * 10
So 110*n is ten times bigger than 11 * n.
Answer:
A = 4 cm²
Step-by-step explanation:
The area of a triangle is calculated as
A =
bh ( b is the base and h the perpendicular height )
b = AC = 3
+
= 4
h = BD
Calculate BD using Pythagoras' identity in Δ ABD
BD² = AB² - AD²
= (2
)² - (3
)²
= 20 - 18 = 2 ( take square root of both sides )
BD = 
Then
A =
× 4
×
= 2 ×
×
= 4 cm²
