Solving for the elapsed time

distance traveled = (speed of first train + speed of second train) * elapsed time

280 miles = (95 mph + 105 mph) * elapsed time

280 miles = 200 mph * elapsed time

elapsed time = 280 miles / 200 mph

elapsed time = 1.4 hours

elapsed time = 1 hour and 24 minutes

It will take 1 hour and 24 minutes for the two trains to be 280 miles apart.

Find the length of the unknown side​
wel
If leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)
if leg b is unknown, then. b = √(c² - a²)
for hypotenuse c missing, the formula is. c = √(a² + b²)

Find the equation of the line graphed below. Write the equation in the form y = mx + b and identify m and b m = b =
Alla [95]

ANSWER:

m = -3/4

b = -3

y=-\frac{3}{4}x-3

STEP-BY-STEP EXPLANATION:

We have that the equation in its slope-intercept form is the following:

\begin{gathered} y=mx+b \\ \text{where m is the slope and b is y-intercept} \end{gathered}

We calculate the slope as follows:

m=\frac{y_2-y_1}{x_2-x_1}

To calculate the slope we use the intercepts that are (-4, 0) and (0, -3), we replace:

m=\frac{-3-0}{0-(-4)}=\frac{-3}{4}=-\frac{3}{4}

Now, the value of b would be -3, since the y-intercept is (0,-3), therefore, the equation would be:

y=-\frac{3}{4}x-3

Using the pythagorean theorem, calculate the length of the missing sides (c1, c2, c3)​
katrin [286]

Answer:

the Pythagorean theorem states:  a^2 + b^2 = c^2  

1) in this case a=18 and b1=25

18^2 + 25^2 = c1^2  

324 + 625 = c1^2

949 = c1^2

√949 = c1

cca. 30.8 = c1

2) in this case a=18 and b' = b2 - b1 = 40 - 25 = 15

in the picture im attaching i highlighted the triangles we are working with, and there you can clearly see that b' (the horizontal line at the bottom of the red tr.) is the difference between the lines b2 and b1

now you can use the same technique as in the first case, and the final answer will be cca. 23.4 = c2

3) in this case a=18 and b'' = b4 - b3 = 75 - 55 = 20

same thing as number 2, final answer cca. 26.9 = c3
