Answer: The correct answer is 22.31 miles to the gallon.
Step-by-step explanation: If she travels 348 miles, and used 15.6 gallons of gas, you would divide 348 by 15.6= 22.307 or 22.31 miles to the gallon.
B - 8 = 5
------ ---
b + 9 2
Cross Multiply
2(b-8)=5(b+9)
distribute
2b -16 = 5b + 45
subtract 5b from both sides
-3b - 16 = 45
add 16 to both sides
-3b = 61
divide both sides by -3
b = -61/3 or -20 1/3
The value of sin(30°) is: One-half ⇒ 2nd answer
Step-by-step explanation:
In a right triangle there are two acute angles, the side opposite to the right angle is called hypotenuse, and the other two sides are opposite and adjacent to the acute angles
- sine the acute angle (sin) = opposite side to it/hypotenuse
- cosine the acute angle (cos) = adjacent side to it/hypotenuse
- Tangent the acute angle (tan) = opposite side to it/adjacent side to it
In Δ QRS:
∵ m∠QRS = 90°
∵ SQ is opposite to ∠QRS
∴ SQ is the hypotenuse
∵ SQ = 10 units
∴ The hypotenuse = 10
∵ m∠RSQ = 30°
- The opposite side to ∠RSQ is RQ
∵ RQ = 5 units
∴ The opposite side to the angle of 30° = 5
∵ sin(30°) = opposite side to 30°/hypotenuse
∵ The opposite side to angle 30° = 5
∵ The hypotenuse = 10
∴ sin(30°) = 
∴ sin(30°) = 
The value of sin(30°) is: One-half
