Answer:
r = 15.2
Step-by-step explanation:
Where AB meets the circle creates a right angle. This is a right triangle problem involving missing sides. This means that we will use Pythagorean's theorem to find the length of the radius. Pythagorean's theorem applies this way:
Foiling the right side gives us the equation:
When we combine like terms, we find the squared terms cancel each other out, leaving us with
100 = 6r + 9 and
91 = 6r so
r = 15.2
Answer:
V(x) = (x +4)(x +2)(2x +11)
Step-by-step explanation:
For length L = (x+4), the height is ...
2L +3 = 2(x+4) +3
= 2x +8 +3
= 2x +11
The volume is the product of length, width, and height, so is ...
V = (x +4)(x +2)(2x +11)
The answer should be D.
The square root of two.
Answer:
x=lizards y=snakes
x+36=y x+y=214
x + x +36=214
2x=214-36
2x/2=178/2
x=89lizards y=89+36=125snakes
Step-by-step explanation:
f= female sankes m=male snakes
m+31=f
m+f=125
m+m+31=125
2m=125-31
2m/2=94/2
m=47 male snakes
f=47+31=78female snakes
