Divide the speed value by 1.609,
1kilometer per hr=0.621mph
80kph=49.7097Mph

<u>Answer:</u>

49.6 miles per hour

<u>Step-by-step explanation:</u>

We know that the vehicle which met an accident in Germany was driven at 80 kilometers per hour by the driver.

To find out how many miles per hour was the driver traveling, we can use the ratio method.

1 kilometer = 0.62 mile

80 kilometers = x

Finding x:

x = 0.62 * 80

x = 49.6

So the driver was traveling at 49.6 miles per hour.

3) An existing track is perpendicular to y=1/2x + 2 and passes through B(7,5)
stira [4]

Answer:

2. y=\frac{1}{2}x +3

Step-by-step explanation:

2. The line will be parallel to the current track which means they have the same slope. To write the equation, use the slope m=1/2 and the point (2,4) in point slope form:

y-y_1=m(x-x_1)\\y-4=\frac{1}{2}(x-2)

This is the equation of the line. You can convert it to slope intercept form:

y-4=\frac{1}{2}(x-2)\\y-4 = \frac{1}{2}x -1 \y=\frac{1}{2}x +3

Use the distance formula to find the perimeter. Round to the nearest tenth.
Ierofanga [76]

Answer:

37.6 units

Step-by-step explanation:

Perimeter = sum of all sides of the triangle

To find the sum, find the distance between each points.

✔️Distance between points (-7, 6) and (5, -4):

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} =

= \sqrt{(5 - (-7))^2 + (-4 - 6)^2}

= \sqrt{(12)^2 + (-10)^2}

= \sqrt{144 + 100}

= \sqrt{244} = 15.6 units (nearest tenth)

✔️Distance between (-7, 6) and (-7, -4):

|6 -(-4)| = 10 units

✔️Distance between (-7, -4) and (5, -4)

|-7 - 5| = 12 units

✔️ Perimeter = 15.6 + 10 + 12 = 37.6 units

Please help. im lost. Question is in the picture
navik [9.2K]

In triangle QRT and triangle RTS , we have;
1.QR =SR (given)
2.RT bisects QS at T ( given )
3.T is the midpoint of QS (since RT is the bisector of QS i.e. QT=TS)
4.QT=TS (mid Point theorem)
5.TR=TR (common side)
6.triangle QRT congruent to triangle RTS (SAS criterion rule)
Hope this helps u....!!!
