Answer:
Step-by-step explanation: bro use sin=opposite/hypotenuse
Answer:
D
Step-by-step explanation:
first multiply both sides by 12
collect like terms
x/12×12+3×12<=7×12
x+36<=84
x<=84-36
x<=48
Answer:
$44.94
Step-by-step explanation:
400+100+100 = 600
22.40 + 10 +10 = 42.40
(22.40 for the first 400 and 10 for each additional 100)
If tax is 6%, you can multiply the whole thing (42.40) by 1.06 to get the total amount of 44.94.
Why 1.06? If you think about it, tax is 6%. 6% is the same as 0.06. You pay 100% for the products, so with tax, it's the equivalent of 106%, or 1.06.

Step-by-step explanation:
The n th term of an AP is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given
6(a₁ + 5d) = 13(a₁ + 12d) ← distribute parenthesis on both sides
6a₁ + 30d = 13a₁ + 156d ( subtract 13a₁ from both sides )
- 7a₁ + 30d = 156d ( subtract 30d from both sides )
- 7a₁ = 126d ( divide both sides by - 7 )
a₁ = - 18d
Now
a₁₉ = a₁ + 18d = - 18d + 18d = 0 ← as required
