Answer:
<BCA = 44.4°
Step-by-step explanation:
Reference angle = <BCA = C
Opposite side length = x = 7 cm
Hypotenuse = y = 10 cm
Applying trigonometric ratio, we would have:
![sin(C) = \frac{7}{10}](https://tex.z-dn.net/?f=%20sin%28C%29%20%3D%20%5Cfrac%7B7%7D%7B10%7D%20)
![C = sin^{-1}(\frac{7}{10})](https://tex.z-dn.net/?f=%20C%20%3D%20sin%5E%7B-1%7D%28%5Cfrac%7B7%7D%7B10%7D%29%20)
![C = 44.427004](https://tex.z-dn.net/?f=%20C%20%3D%2044.427004%20)
<BCA = 44.4° (to 3 SF)
Answer:
The Pacific seahorse eats 8 shrimp per day
Step-by-step explanation:
<u><em>The complete question is</em></u>
As a part of its diet, a Pacific seahorse eats about 56 shrimp per week. It eats the same amount each day.
a) How much shrimp does the Pacific seahorse eat per day?
Complete the statement with the unit rate.
The Pacific seahorse eats _____ shrimp per day.
Part a) How much shrimp does the Pacific seahorse eat per day?
Let
x ---> the number of shrimp that the Pacific seahorse eats per day
we know that
The number of shrimp that the Pacific seahorse eats per day, multiplied by the number of days in a week, must be equal to 56 shrimp
![1\ week=7\ days](https://tex.z-dn.net/?f=1%5C%20week%3D7%5C%20days)
so
The linear equation that represent this situation is equal to
![7x=56](https://tex.z-dn.net/?f=7x%3D56)
solve for x
Divide by 7 both sides
![x=8\ shrimp](https://tex.z-dn.net/?f=x%3D8%5C%20shrimp)
therefore
The Pacific seahorse eats 8 shrimp per day
Answer:
8
Step-by-step explanation:
so the top would equal 250000 and the bottom part of this equation would equal 125000. So you'd do 250000/125000 = 2. After that you would do 2 x 2 x 2 which gives you 8.
