Answer:
1/4
Step-by-step explanation:
8 blue chips 9 pink chips 1 white chip = 18 chips
P( pink) = pink/total = 9/18 = 1/2
Replace
8 blue chips 9 pink chips 1 white chip = 18 chips
P( pink) = pink/total = 9/18 = 1/2
P(pink, replace, pink) = 1/2 * 1/2 = 1/4
Answer:
5
Step-by-step explanation:
6/2 = 3
because the triangle is halved
use pythagorus 3²+4²=25
√25 = 5
so x=5
Answer:
Step-by-step explanation:
We are given the two functions:
And we want to find:
Recall that this is equivalent to:
Hence, find g(-1):
Substitute:
Find f(1):
In conclusion:
Question restated.
which is not equivalent to d = rt?
r = t/d
r = d/t
t = d/r
d = tr
If we divide both sides of the original equation by t, we are left with r = d/t, so we know that this is true. if we compare this, however, with the first item on the list, we can see that t/d does not equal d/t, so the first item on the list is the wrong one.
Answer:
11 inches
Step-by-step explanation:
We want to work out the radius of the cylinder in inches so we have to utilise the volume of a cylinder formula which is
Volume = π × r² × h
Where "r" is the radius and "h" is the height
→ First substitute the value into the formula
121 π = π × r² × 1
→ We can divide both sides by π to get rid of it
121 = r² × 1
→ We should divide both sides by 1 to isolate r²
121 = r²
→ Now, we can square root both sides to find the value of the radius
11 = r
→ So the radius of the cylinder is 11 inches
