Answer:
b=8
Step-by-step explanation:
This is a right triangle, as we can see from the box in the corner.
We can use Pythagorean theorem to find the unknown side
a^2 +b^2 = c^2
where a and b are the legs and c is the hypotenuse
15^2 +b^2 = 17^2
225 + b^2 =289
Subtract 225 from each side
225-225 + b^2 = 289-225
b^2 =64
Take the square root of each side
sqrt(b^2) = sqrt(64)
b = 8
The santos because they rented the car for two weeks, while the others rented for four.
2 + -9n = 56. -9n = 54. N = -6
Answer:
18 ferrets
Step-by-step explanation:
From the statement you can write the following:
c+r+f= 108
c=cats
r= rabbits
f= ferrets
Then, you have that one third of the animals are cats:
c= 108*(1/3)= 36
Next, three fourths of the remaining animals are rabbits:
r= (108-36)*(3/4)= 72*(3/4)= 54
Now, as you have determine the amount of cats and rabbits, you can isolate f and find the amount of ferrets:
f=108-c-r
f=108-36-54
f= 18
According to this, the answer is that there are 18 ferrets.
