Answer:
4/b
Step-by-step explanation:
7/b - 3/b
Since the denominators are the same, we can subtract
4/b
7 girls participated only in Karate.
21 + 8 = 29
29 + 7 = 36
36 + 6 = 43
Answer:
24.03 units (nearest hundredth)
Step-by-step explanation:
The distance between B and A is: AB = AH + HB
We have been given AH, so we just need to find the measure of HB.
First, find the angle AOH using tan trig ratio:

where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
Given:
= ∠AOH- O = AH = 8
- A = OH = 19.80


∠BOA = ∠BOH + ∠AOH
⇒ ∠BOH = ∠BOA - ∠AOH
⇒ ∠BOH = 61° - 22.00069835°
= 38.99930165°
Now we can find HB by again using the tan trig ratio:
Given:
= ∠BOH = 38.99930165°- O = HB
- A = OH = 19.80
Substituting given values:



Therefore:
AB = AH + BH
⇒ AB = 8 + 16.03332427
= 24.03 units (nearest hundredth)
Setup
0.8x + 0.4y = 50
0.1x + 0.2y = 10 - Multiply by -2 and add
get
0.6x = 30
x = 50 mg compound A
.1 (50) + .2y = 10
5 + .2y = 10
.2y = 5
y = 25 mg compound B
