Given:
A bricklayer is able to set 2.5 bricks in one minute.
Required:
To find the number of bricks can he set in 8 hours.
Explanation:
8 hours =480 minutes.
2.5 bricks in one minute.
So for 480 minutes,
Final Answer:
1,200 bricks can he set in 8 hours.
You would use the Law of Sines here. First realize that if A and B equal 35 and 65 respectively, C=180-65-35=80°. Then from the Law of Sines:
b/sin65=15/sin80
b=15sin65/sin80
b≈13.8 units (to the nearest tenth of a unit)
Answer:
1/9
Step-by-step explanation:
The possible choices 2,3,4
odd numbers: 3
P (odd number) = number of odd numbers /total
= 1/3
Then we spin again
The possible choices 2,3,4
We want a 3: 3
P (3) = number of 3's /total
= 1/3
Since the first spin did not affect the second spin
P(odd, then 3) = P(odd) *P( 3)
= 1/3* 1/3
=1/9
Answer:
x = 19/3
Step-by-step explanation:
30 - 11 = 3x
3x = 19
x = 19/3
hope it helps!
