Apparent magnitude isn’t the actual brightness, it’s what the brightness appears to be from earth, absolute brightness is the actual brightness an example is our sun it appears bright on earth but in space it is so much more brighter
Answer:
ok wait which symbol? this (<)?
well it should stay the same since -100 is greater than the 11b-12
LHS=RHS
11b÷11b b must cancell b also do the same on -12. -12÷11 will give u a lesser value compared to -100
prove me wrong
Answer:
-3.5
Step-by-step explanation:
We have to find the distance between x and z along the y-axis.
This will be: 5 - -6 = 11 units
1/5 th of 11 = 1/5 × 11
= 11/5
= 2 1/5 = 2.5
Now add 2.5 to -6
2.5 + -6 = -3.5
The value of y = -3.5
Answer:
A) 3/4
Step-by-step explanation:
Given: Both circle A and circle B have a central angle measuring 50°.
The area of circle A's sector is 36π cm2.
The area of circle B's sector is 64π cm2.
We know, area of the circle= 
lets assume the radius of circle A be "
" and radius of circle B be "
"
As given, Area of circle A and B´s sector is 36π and 64π repectively.
Now, writing ratio of area of circle A and B, to find the ratio of radius.
⇒
Cancelling out the common factor
⇒ 
⇒ 
Taking square on both side.
Remember; √a²= a
⇒ 
⇒ 
⇒
Hence, ratio of the radius of circle A to the radius of circle B is 3:4 or 3/4.
