22 & 23) x = 10 (solved for x in 5x+80=3x+100)

5x + 80 = 130 degrees (angle LMN)

3x + 100 = 130 degrees (angle PMQ)

130 * 2 = 260 degrees

360 - 260 = 100

100 / 2 = 50 degrees (angle LMP and angle NMQ)

24) 60 degrees and 30 degrees. 60 is twice as large as 30, and they bothd this  add up to 90 degrees.

Complementary angles add up to 90 degrees *

Yes because when ever there is a variable the number in front of it is always 1. In this case it os both 1 and a negative number. So yes it would be the same.

Una ambulancia se desplaza hacia el norte a 23,5 m/s. Su sirena emite un sonido de 500Hz de frecuencia. Calcular la frecuencia a
aliya0001 [1]

Answer:

(I attach your complete question in the picture below)

The apparent frequency would be  

f' = 493.26 Hz

Step-by-step explanation:

This a Doppler's effect problem. This effects produces a slight change in the frequency of a traveling wave, due to the effect of the velocity of the receiver (observer).

The formula used to describe the change, as both vehicles are moving away of each other:

f' = [ (Vwave + Vobserver) / (Vwave + Vsource ) ]*f

Where  

Vwave = 340 m/s ( speed of sound)

Vobserver = 18.6 m/s (observer = car)

Vsource = 23.5 m/s (speed of the ambulance = source)

f = 500 Hz (frequency of the sound)

We just need to substitute in the equation

f' = [(340+ 18.6) / (340+ 23.5)] * 500 Hz

f' = [0.9865] * 500 Hz = 493.26 Hz

f' = 493.26 Hz

The lateral area of a cone is 555 \pi cm^2 and the radius is 15.1 what is the slant height?
pishuonlain [190]
We know that
[LA]=pi*r*l
where
LA is the lateral area of the cone
r is the radius
l is the slant height
l=LA/(pi*r)
r=15.1 cm
LA=555*pi cm²
l=(555*pi)/(pi*15.1)----> l=36.75 cm

the answer is
the slant height is 36.75 cm
