Answer:
14.4
Step-by-step explanation:
We solve the above question using Cosine Rule
The formula is given as:
BC² = AB²+ AC²﹣2 × AB × AC cos A
BC² = 6² + 13²﹣2 × 6 × 13 × cos(91°)
BC = √6² + 13²﹣2 × 6 × 13 × cos(91°)
BC = 14.41258
Approximately
BC = 14.4

Answer:
A. Algebraic, common difference = −10
Step-by-step explanation:
The difference between the first two terms is -10, as it is between the next two terms. The ratio of the first two terms is -1; of the next pair: -15/-5 = 3. There is a common difference, but not a common ratio.
The sequence is algebraic with a common difference of -10.

Answer:
<em>a. 15.12 L / 100 Km</em>
<em>b. $72.75</em>
<em>c. $51.34</em>
Step-by-step explanation:
Proportions
Some quantities are assumed to be proportional to others. For example, the fuel consumption of a vehicle is said to be proportional to the distance traveled. The cost of the fuel is proportional to the liters used.
We have the following data: The odometer read 5,600 km when the tank was empty and read 6,096 km when he was empty again. It means a full tank of fuel is enough to travel a distance of 6,096 - 5,600 = 496 Km. Knowing the capacity of the tank is 75 L, we can estimate the following calculations
. We'll compute the estimated or average fuel consumption of the SUV in L/100 km. We only need to divide 75 L / 496 km = 0.1512096 L/km, multiplying by 100:
Answer: 0,1512096*100 = 15.12097 L/100 Km
b. The price of the fuel is $0.97 per liter. Each tank has 75 liters, so the cost to fill the tank is 0.97*75= $72.75
c. If Paul drives at least 350 Km per week, he needs 0.1512096*350= 52.92 Liters of fuel. The weekly cost will be 52.92*0.97=$51.34
