Answer:

Step-by-step explanation:

Again taking proportionality between their any two sides as the two triangles as considered separate are similar

AB/AC=AD/AE

4/6=7/AE

cross Multiplying

4×AE =6×7

AE=42/4

AE=10.5

Find the slope of the line that passes through points (3,5) and (8,5)

Katyanochek1 [597]

Answer: m = 0

Step-by-step explanation: To solve this problem, we don't even have to use our slope formula. It's important to understand that when we have the same y coordinate in our first ordered pair and our second ordered pair, this means that the line will be flat or horizontal.

When a line is horizontal, it means the line has a slope of zero.

We use the variable m to represent slope.

So here, we can say that m = 0.

75 POINTS Need an immediate answer please brainliest will be given! A train left a station travelling to a city at 30 mph. The t

yaroslaw [1]

The value of distance between the station and the city in terms of miles which train and car travelled at interval of 2 hours is 129.6 miles.

<h3>What is the rate of speed?</h3>

The rate of speed is the rate at which the total distance is travelled in the time taken. Rate of speed can be given as,

r=d/t

Here, (d) is the distance travelled by the object and (t) is time taken but the object to cover that distance.

The train traveled 1/3 of the distance at 30 mph and the remaining distance at 40 mph. Let t is the time the train has taken to travel and x is the distance it travelled. Thus,

$t=\dfrac{\dfrac{1}{3}x}{30}+\dfrac{\dfrac{2}{3}x}{40}\\t=\dfrac{x}{90}+\dfrac{x}{60}\\t=\dfrac{2x+3x}{180}\\t=\dfrac{5x}{180}\\t=\dfrac{x}{36}$

After two hour a car left the same station traveled the first 3 hours at 35 mph and the remaining distance at 51 mph. Let t is the time the car has taken to travel and x is the distance it travelled. Thus,

$t+2=3+\dfrac{(x-3\times35)}{51}$

As t is same, thus put the value of t in this equation,

$\dfrac{x}{36}=3-2+\dfrac{(x-3\times35)}{51}\\\dfrac{x}{36}=3-2+\dfrac{(x-3\times35)}{51}\\\dfrac{x}{36}=1+\dfrac{(x-105)}{51}\\\dfrac{x}{36}=\dfrac{(51+x-105)}{51}\\51x=36x-54\times36\\51x-36x=1944\\x=\dfrac{1944}{15}\\x=129.6$

Thus, the value of distance between the station and the city in terms of miles which train and car travelled at interval of 2 hours is 129.6 miles.

Fatima plotted one side of a heptagon on a grid. the points (-8,1) and (-8,8) are joined to form a side of the heptagon. Fatima

Reil [10]

The general formula for the distance between two points is

$d(A,B) = \sqrt{(A_x-B_x)^2 + (A_y-B_y)^2}$

Anyway, if A and B have the same x or y coordinates, this formula can be simplified. For example, in this case the two points have the same x coordinate of -8, so the following part of the formula simplifies:

$(A_x-B_x)^2 = (-8-(-8))^2 = (-8+8)^2 = 0^2 = 0$

So, we're left with

$d(A,B) = \sqrt{(A_y-B_y)^2}$

but the square root of a square is the absolute value of the object being squared:

$d(A,B) = \sqrt{(A_y-B_y)^2} = |A_y-B_y|$

which is this case means $|1-8| = |-7| = 7$

which is the correct length of the side.
