Two trains leave Stations 396 miles apart at the same time and travel towards each other. One train travels at 95 mph while othe

PolarNik [594]

It will take 2.2 hours for the trains to meet.

Step-by-step explanation:

Given,

Distance between two trains = 396 miles

Speed of one train = 95 mph

Speed of other train = 85 mph

Combined speed of trains = 95+85 = 180 mph

Distance = Speed * Time

Time = $\frac{Distance}{Speed}$

Time = $\frac{396}{180}$

Time = 2.2 hours

It will take 2.2 hours for the trains to meet.

How do I use intercepts to graph 3y= - 5x - 30

expeople1 [14]

Answer:

y-intercept is (0,-10) and x-intercept is (-6,0). Connect them by a straight line to graph the given equation.

Step-by-step explanation:

The given equation of line is

$3y=-5x-30$

For x=0,

$3y=-5(0)-30$

$3y=-30$

$y=-10$

So, y-intercept is at point (0,-10).

For y=0,

$3(0)=-5x-30$

$0=-5x-30$

$5x=-30$

$x=-6$

So, x-intercept is at point (-6,0).

Now, plot the point (0,-10) and (-6,0) on a coordinate plane and connect them by a straight line to graph the given line as shown below.

Write a ratio and a percent for the shaded figure.

trapecia [35]

Total Squares = 10 × 10

= 100

Shaded Squares = 100 - (6×6)

= 64

Non Shaded = 6 × 6

= 36

Now Ratio of shaded portion is 64:100

= 16:25

Percentage = 64/100 × 100

= 64%

What is the length of the radius of a circle with a center at 2 – i and a point on the circle at 8 + 7i?

AlladinOne [14]

We need to find a distance between this to points.
D=√((x2-x1)²+(y2-y1)²)

For complex plain, the real part of the complex number plays a role of x,
and number of an imaginary part plays a role of y.
So,
D=√((8-2)² +(7+1)²)√ = √(36+64)=√(100)=10
Answer is D.10
