Answer:
The value of y is 3 cm.
Step-by-step explanation:
Given,
Perimeter of triangle = 
Solution,
Lets redraw the triangle with nomenclature ABC, given in the attachment.
∴P(ΔABC) = 29 cm (P stands for perimeter)
Length of AB = 
Length of BC = 
Length of CA = 
Now, we all know that the perimeter of a triangle is sum of all the three sides of triangle.
P(ΔABC) = Length of AB+Length of BC+Length of CA
On substituting the values, we get;
Length of AB =
Length of BC =
Length of CA =
Hence the value of y is 3 cm.

Step 1: Let a = b.
Step 2: Then a^2 = ab ,
Step 3: a^2 + a^2 = a^2 + ab ,
Step 4: 2a^2=a^2 + ab,
Step 5: 2a^2 - 2ab = a^2 + ab - 2ab,
Step 6: and 2a^2 - 2a^b = a^2 + ab - 2ab .
Step 7: This can be written as 2(a^2 - ab) = 1(a^2 - ab) ,
Step 8: and cancelling the (a^2 - ab) from both sides gives 1 = 2.</span>
Answer:
522
Step-by-step explanation:
The assumption is that the proportion of tagged fish caught is the same as the proportion of all fish that were caught and tagged:
(all fish)/(number tagged) = (sample size)/(number in sample tagged)
all fish = (number tagged) · (sample size)/(number in sample tagged)
all fish = 174 · 39/13
all fish = 522
If all the assumptions are reasonable, the number of fish in the lake is estimated at 522.
Answer:
7/12
Step-by-step explanation:
30+40+50=120
120 buttons in total
30+40=70
70 buttons that aren't white
70/120 is the probability
Simplify that to 7/12
