Answer:
0.13
Step-by-step explanation:
1 represents the whole class
1-0.87=0.13
Well 1 pound = 16 ounces so 1 and there would be some left over
Answer:
B. x = 8
Step-by-step explanation:
Answer:
12.4967 m
≈ 12.5 m
Step-by-step explanation:
From the solution diagram attached, to find /AB/, we apply sine rule:
AB/Sin 140° =AD/Sin 15°
AB = 10/Sin 15° x Sin 140°
= 24.8372 m
To calculate the height of the pole we will calculate BC first. Using the right angle triangle ∠ABC, we have:
Sin ∅ = BC/AB
Sin 25° = BC/ 24.8372
BC = 24.8372 Sin 25°
= 10.4967 m
The height of the pole = BC + 2.0
= 10.4967 + 2.0
= 12.4967
≈ 12.5 m
Let's first determine the total number of the students.
=> 10 freshman
=>12 sophomores
=>15 juniors
<span>=> 30 seniors in the club. </span>
Since the adviser will only chose 1, let's add then divide by 4 to get the average.
=> 10 + 12 +15 + <span>30 = 67 students
</span>=> 67 / 4 = 16.75
OR close to
<span>=> 15/67</span>
