Answer:
r+7
Step-by-step explanation:
Given that C is the midpoint of AB so from this result that AC = BC so given that AC = 20 => BC = 20 too
and given that AB = 5x so AB = AC +BC so AB = 20+20 so AB = 40
than AB = 40 and AB = 5x so result 5x = 40 => x = 40/5 so x = 8
hope this will help you
56/306= 7/34
the right answer for 7 is 7/34 since 8*7/17*16
8-15/3.2(pi d)=4.68 round up you get 5
you need 5 laps
3/4 X 7/1=5 1/4 Then, 5 1/4+5 1/4=10 1/2. Answer 10 1/2
Complete question is;
Leslie is a biologist. She is going to randomly select one animal from her lab to study. There are 5 salamanders, 3 crayfish, and 12 minnows in her lab. What is P(salamanders).
Answer:
P(salamanders) = 0.25
Step-by-step explanation:
We are given;
number of salamanders = 5
number of crayfish = 3
number of minnows = 12
total number of animals; n = 5 + 3 + 12 = 20 animals
Now, we want to find out the probability that the animal Leslie randomly selected is a Salamander.
Thus,
P(salamander) = number of salamanders/total number of animals
P(salamander) = 5/20
P(salamander) = ¼ = 0.25
