Answer:
49.1 cm² (round to nearest 10)
Step-by-step explanation:
- use trigonometry to find the <em>h</em><em>e</em><em>i</em><em>g</em><em>h</em><em>t</em><em>(</em><em>h</em><em>)</em><em> </em>of the triangle 
- substitute height and base(b) 12cm into the formula
 <em>A</em><em> </em><em>=</em><em> </em><em>½</em><em> </em><em>×</em><em> </em><em>b</em><em> </em><em>×</em><em> </em><em>h</em><em> </em><em>.</em>
 
        
             
        
        
        
Answer:
   9 years
Step-by-step explanation:
You want to find t such that y=10.
   10 = 7.67(1.03)^t
   10/7.67 = 1.03^t . . . . . divide by 7.67
   log(10/7.67) = t·log(1.03) . . . . . . take logs
   log(10/7.67)/log(1.03) = t ≈ 8.9743 . . . . . years

Answer:
x = 9 1/3 ounces of almonds
 
Step-by-step explanation:
Ounces of almonds : raisins
= 7 : 5
Total = 7 + 5
= 12
How many ounces of almonds would be in a one-pound bag (16 ounces) of this trail mix
Let
x = Ounces of almonds needed
x = 7 /12 × 16
= 112 /12
= 9 4/12
= 9 1/3 
x = 9 1/3 ounces
