1 answer:

6 0

First: 240km/1hour=120km/?hour
Cross multiply and divide
(120*1)/240= 0.5hour
Second: 220km/1hour=120km/?hour
Cross multiply and divide
(120*1)/220=0.545hour
Third: 210km/1hour=120km/?hour
Cross multiply and divide
(120*1)/210= 0.571hour
Fourth: 205km/1hour=120km/?hour
Cross multiply and divide
(120*1)/205= 0.585hour
Fifth: 200km/1hour=120km/?hour
Cross multiply and divide
(120*1)/200= 0.6hour

Find the distance between line 11x-60y-15=0 and point (2, 1/60)

vovikov84 [41]

Answer:

The answer to your question is: d = 6 / 61 or 0.1 units

Step-by-step explanation:

Data

Line: 11x - 60y - 15 = 0 A = 11; B = -60; C = -15

Point (2, 1/60) x = 2 y = 1/60

Formula

d = | Ax + By + C | / √(A² + B²)

Process

d = | (11)(2) + (-60)(1/60) -15 | / √(11² + (-60²)

d = | 22 -1 - 15 | / √ 121 + 3600

d = | 6 | / √3721

d = | 6 | / 61

d = 6 / 61 or 0.1 units

Find X in the problem below <br> X=In

xxTIMURxx [149]

Answer:

Step-by-step explanation:

Let's drag the x line to the other side with the 14 and 48.

Then we do the Pythagorean theorem like 14^2 + 48^2 = x^2.

So then we get that x^2 is 2500

then we clearly know the square root of 2500 is 50

So 50 is our answer.

Isla made a diagram to compare X-rays and radio waves

Licemer1 [7]

a: has a higher frequency

c: has a longer wavelength

b: travels at the same speed

Step-by-step explanation:

The diagram, a Venn diagram is set to describe the properties of the electromagnetic waves of x-rays and radio waves. Also, to see the mutual properties that connects them.

Electromagnetic waves do not require a material medium for their propagation. They all travel at the same speed known as the speed of light 3 x 10⁸m/s.

On the spectrum which shows the wavelength and velocities of electromagnetic radiations,

X-rays are energetic waves with a high frequency and short wavelength.
Radio-waves on the other hand have low frequency and long wavelength.

E = h f = $\frac{h c}{x}$

h is a constant known as planck's constant

f is the frequency

c is the speed of light

x is the wavelength

The speed of light is the union of the two points A and B which is the point C.

We see that there is an inverse relationship between frequency and wavelength.
