The speed of the airplane is the ratio of the distance to the time

The initial average speed of the airplane is approximately 110.8 mph

Reason:

Given parameters are;

The distance between Portland Oregon and Seattle Washington = 145 miles

The decrease in travel time when the speed is increase by 20 mph =  minutes

The initial speed of the airplane, v = Required;

Solution;

[tex]t = \dfrac{145}{v}[/tex]

[tex]t - \dfrac{12}{60} = \dfrac{145}{v + 20}[/tex]

Therefore;

[tex]\dfrac{145}{v} - \dfrac{12}{60} = \dfrac{145}{v + 20}[/tex]

Which gives;

[tex]\dfrac{145}{v + 20} - \dfrac{145}{v} + \dfrac{12}{60} = 0[/tex]

Therefore

0.2·v² + 4·v - 2,900 = 0

v ≈ ±110.8 mph

The initial average speed of the airplane, v≈ ± 110.8 mph

Line segment L'M' has a slope of 6 and passes through point H.

Given that line segment LM is dilated by a scale factor of to form L'M'. Statement D). is true.

The dilation of a line segment is longer or shorter in the ratio given by the scale factor. If the scale factor is greater than 1 (k > 1), the image will be larger than the pre-image, making the segments (sides) of the image longer than the corresponding sides of its pre-image (an enlargement).

When a line segment gets dilated, it gets longer or shorter. But, the slope does not change. Also, the center of dilation which lies on the line segment, stays on the line only. Thus, D). is true.

Step-by-step explanation:

This is because if you go left or right it changes the x in (x,y). And when you move up or down it changes the y. So 5 seven units to the left is like 5 - 7 which is -2. And one unit up from -3 is -3 + 1 which is -2. Then you get your answer which is (-2,-2)

Answer:

a^(4/15)

Step-by-step explanation:

rules of indices:

WHEN MULTIPLYING POWERS WITH THE SAME BASE YOU ADD THE POWERS

a^(1/5) × a^(2/3) = a^(1/5 + 2/3)

a^(13/15)

WHEN DIVIDING POWERS WITH THE SAME BASE YOU SUBTRACT THE POWERS

a^(13/15) / a^(3/5) = a^(13/15 - 3/5)

a^(4/15)

Answer:

x=176 degrees

Step-by-step explanation:

The first step to solving this is filling out any information we have. We know a solid line is 180 degrees, so the angle next to 92 must be 88.

We also know that the length of the line dividing 92 and 88 is equal to the other line with a small line in the middle. Because of this, the angle above the first 88 we found is also 88 degrees.

Now that we know two of the angles in the triangle add up to 176, we can figure out that the other angle is equal to 4. We know this because the sum of the interior angles of a triangle must equal 180.

This may seem off to you, but keep in mind that this diagram is likely not to scale.

Using the same rule we used for the first part we did, we can deduce that x equals 176.

Answer:

D) 20⁰

Step-by-step explanation:

EDF = 180-100=80⁰

EFD= 80⁰+80⁰=160⁰

180⁰-160⁰=20⁰

Answer:

I would say D, 20°

Step-by-step explanation:

angles on a straight line should be equal to 180°. so 180 -100 = 80° inside.

angles inside a triangle should also be 180. So, 80° + 80° =160°. to get the other angle subtract 160 from 180 to get 20°
