Answer:
The jet flies 755.32 miles east after flying for 1.7hrs at a bearing of 50 degree North.
Step-by-step explanation:
The distance covered by the jet can be deducted from velocity = distance / time
therefore distance = velocity x time
distance = 580miles/hr x 1.7hrs
= 986 miles
At bearing of 50°, distance towards the east can be generated using the right angle triangle model such that the distance covered x miles can be generated using Sin(theta) = opp/hyp as shown in the attached diagram
theta is the angle covered = 50°
opposite is the distance covered by the jet towards the east (x)
hypotenuse is the distance covered after flying for 1.7hrs
therefore Sin(50) = x / 986
x = 986 Sin 50
x = 986 × 0.7660
x = 755.32 miles
Answer:
Answer is 6.5 dollars.
Step-by-step explanation:
Cost of movie tickets and snacks in total = 43.50
Cost of tickets = $24
Cost of Snacks = 43.50-24 =19.5$
number of snacks = 3
Cost of one snack = 19.5 ÷ 3 = 6.5$
Answer:
x = 3
Step-by-step explanation:
29 - 3x = 5x + 5
You want to have the variable of x on one side of the equation, so add 3x to both sides.
29 = 8x + 5
You want to isolate the variable of x, so subtract 5 from both sides.
24 = 8x
You want the variable x on its own, so divide both sides by 8.
3 = x
Check your answer by plugging x back into the original equation.
29 - 3(3) = 5(3) + 5
Solve.
29 - 9 = 15 + 5
20 = 20
Your answer is correct!
Answer:
b. f(x) = -2x +2
Step-by-step explanation:
The graph has a negative slope (m < 0) and a positive y-intercept (b > 0). The only equation with those characteristics is ...
f(x) = -2x +2
_____
<em>Additional comment</em>
The line on the graph appears to fall by 2 grid squares for each 3 to the right. That means it has a slope of ...
m = rise/run = -2/3
None of the offered equations have that slope. We have to assume the graph is "not to scale". Hence we can only comment on the signs of slope and intercept, and not their values.
