well, clearly the LCD from the denominators of 5 and 10 is just 10, thus
Answer:
A) 4 groups of 9 negatives
Step-by-step explanation:
-36/4
-9
This means we have 4 groups of 9 negatives
Answer:
PB = 1.8
Step-by-step explanation:
PQ = 8 cm, BC = 10 cm and AB = 9 cm
∆ABC is similar to ∆APQ.
Therefore:
Plug in the values
Cross multiply
AP × 10 = 8 × 9
AP × 10 = 72
Divide both sides by 10
AP = 7.2
PB = AB - AP
PB = 9 - 7.2
PB = 1.8
27 is 2/3 of 40 1/2.
Do 27divided by 2/3 to get it
Answer:
A. They have different wavelengths.
B. They have different frequencies.
C. They propagate at different speeds through a vacuum depending on their frequency.
Step-by-step explanation:
Electromagnetic waves have electric and magnetic fields which travel in the free space together. They travel at the speed of light and accelerate by particle oscillates. EM radiations are differently used for different purposes. They are modified in order to create micro waves or radio waves.
