Answer: the rate of speed for train A is 66 miles per hour.
Step-by-step explanation:
Let x represent the speed of train B.
2 trains leave the station at the same time. Train A is traveling 16 miles per hour slower than train B. This means that the speed of train A would be x - 16 miles per hour.
The two trains are 720 miles apart after 4 hours. It means that both trains traveled a total distance of 720 miles in 4 hours.
Distance = speed × time
Distance travelled by train A after 4 hours is
4(x - 16) = 4x - 64
Distance travelled by train B after 4 hours is
4 × x = 4x
Since the total distance travelled by both trains is 720 miles, then
4x - 64 + 4x = 720
8x = 720 - 64 = 656
x = 656/8 = 82 miles per hour
The speed of train A would be
82 - 16 = 66 miles per hour.
13 + the cost of 1 brush + the cost of 1 brush = total money spent
Answer:
The correct option is a.
Step-by-step explanation:
It is given that Nell's mortgage is $50,150 at 10 percent for 30 years and she must pay $8.78 points per $1,000.
<u>EMI on $1000 is $8.78, so EMI on $1 is</u>
EMI on $1 = 8.78/1000 = 0.00878
<u>EMI on $50150 is</u>
<u>EMI on $50150 = 0.00878 x 50150 = 440.317 = 440.32</u>
Therefore the correct option is a.
Hope this help you! ^_^
Uee two points on the line to find the slope.
(-1,2) and (1,-4)
Slope = change in y over change in x;
Slope = (-4 - 2)/ (1 - -1) = (-6/2) = -3/1 = -3
The y intercept is y value where the blue line crosses the y axis, which is at -1
The equation would be y = -3x-1
