Answer:
C = 25.12 , A = 50.24
Step-by-step explanation:
C = 8 * 3.14 = 25.12
A = (4*4) * 3.14 = 50.24
Answer:
3/10
Step-by-step explanation:
So, you already have the experimental probability. The theoretical probability is 5/10, but that's not what you're lookig for.
Answer: x=12
Step-by-step explanation:
- Multiply both sides by 27.
- Use this rule: a/b*c=ac/b
- Simplify 4×27 to 108.
- Simplify 108/9 to 12
Hope this helps, HAVE A BLESSED AND WONDERFUL DAY! As well as a great Superbowl Weekend! :-)

Answer:
48
Step-by-step explanation:
(1/4)16 = 4
48-32-4 = 12 still not posted
checking
32 + 4 + 12 = 48 CHECKS!
To solve this problem, we must recall that the formula
for velocity assuming linear motion:
v = d / t
Where,
v = velocity
d = distance
t = time
For condition 1: bus travelling on a level road
v1 = d1 / t1
<span>(v2 + 20) = (449 – d2) / 4 --->1</span>
For condition 2: bus travelling on a winding road
v2 = d2 / t2
<span>v2 = d2 / 5 --->2</span>
Combining equations 1 and 2:
(d2 / 5) + 20 = (449 – d2) / 4
0.8 d2 + 80 = 449 – d2
1.8 d2 = 369
d2 = 205 miles
Using equation 2, find for v2:
v2 = 205 / 5
v2 = 41 mph
Since v1 = v2 + 20
v1 = 41 + 20
v1 = 61 mph
Therefore
<span>the
average speed on the level road is 61 mph.</span>
