Mathematics
1 answer:
monitta3 years ago
6 0

Answer:

x=28 y=11 z=1

Step-by-step explanation:

plug in 1 for z in x+2z=30 to get x+2(1)=30. Then you should get x+2=30 which is x=28.

Then, plug 1 in for the second equation of y+z=12 so you get y+1=12. Then you should get y=11.

Verify the Pythagorean Identity step by step. 1+cot^2θ=csc^2θ
mestny [16]
This is pretty simple.

If you have a sheet that tells you your identities then you should see that 
1+cot^{2}=csc^{2}
Just change
1+cot^{2} to csc^{2}
and get 
csc^{2}=csc^{2}

Ratio of apples to strawberries in Angie's salad

= 4:5

= 36:45 <em>(because we multiplied both numerator and denominator by 9, to get the same denominator as the other ratio)</em>

Ratio of apples to strawberries in Salim's salad

= 7:9

= 35:45 <em>(because we multiplied both numerator and denominator by </em><em>5</em><em>, to get the same denominator as the other ratio)</em>

36:45 ≠ 35:45

So, ratio of apples to strawberries in Angie's salad ≠ ratio of apples to strawberries in Salim's salad.

36:45 > 35:45

So, ratio of apples to strawberries in Angie's salad < ratio of apples to strawberries in Salim's salad.
