From triangle PQR is P = 90°, PQ = 15.5 dm and PR = 11,7 dm. Calculate QR in dm. Round to one decimal.
Irina18 [472]

Answer:

QR = 19.4

Step-by-step explanation:

Use Pythagoras because p = 90°

Qr is hypotenuse

; (15.5)² + (11.7)²

= 377.14

√377.14

= 19.42009

= 19.42

= 19.4

How does light from stars indicate the universe is expanding?
blondinia [14]

Answer:

So, if a star is moving towards Earth, it appears to emit light that is shorter in wavelength compared to a source of light that isn't moving. ... In contrast, the light from a star moving away from us seems to shift towards longer wavelengths. As this is towards the red end of the spectrum, astronomers call it redshift.

hope this helps

Answer:

A). y=x-\frac{2}{5}

B).  y = 1.8\bar{3}x

Step-by-step explanation:

Question (1)

A). If every block of the given figure represents \frac{1}{5},

    Measure of x = \frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}

                           = 1

    Measure of y = \frac{1}{5}+\frac{1}{5}+\frac{1}{5}

                          = \frac{3}{5}

    Since, \frac{2}{5}=1-\frac{3}{5}

               \frac{2}{5}=x-y

              y=x-\frac{2}{5}

    Therefore, there is a decrease of \frac{2}{5}.

B). Measure of each box = \frac{1}{11}

     y = 11\times \frac{1}{11}

     x = 6\times \frac{1}{11}

     \frac{y}{x}=\frac{11\times \frac{1}{11}}{6\times \frac{1}{11} }

    \frac{y}{x}=\frac{11}{6}

    y=\frac{11}{6}x

    y = 1.8\bar{3}x
