Answer: $820
Step-by-step explanation:
Use a proportion
9.5/100 = 77.90/x
Multiply 77.90 times 100 and divide by 9.5, the answer is $820

Answer:
To find cosθ, use the formula for the area of a triangle i.e. AREA=1/2 x a x b x sinC.=> For this case: 15= 1/2 x 10 x 5 x sinC to find sinC.=> SinC = 3/5 thus, Arcsin(3/5)=+- 4/5 or +-0.8
To find the exact length of BC, use the cosine rule.=> c(sq)=a(sq)+b(sq)-2abCosC=> c(sq)=10(sq)+5(sq)-2(10)(5)(+-4/5)=> c(sq)= Square root of 205
Answer:
1) 0.024
2) 0.033
3) 4.8
4) 0.16
5) 0.084
6) 0.14
Step-by-step explanation:
1. 3 x 0.008 = 0.024
2. 11 x 0.003 = 0.033
3. 12 x 0.4 = 4.8
4. 4 x 0.04 = 0.16
5. 12 x 0.007 = 0.084
6. 7 x 0.02 = 0.14
