Step-by-step explanation:
decimal: 4.375
fraction: 4 3/8
Let r be a radius of a given circle and α be an angle, that corresponds to a sector.
The circle area is
and denote the sector area as
.
Then
(the ratio between area is the same as the ratio between coresponding angles).
.
Answer:
Answer D
Step-by-step explanation:
there needs to be a filled circle since the symbol says "or equal to".
then the arrow needs to point to the left indicating that the answer to x is less that 7, so the answer is D
First of all, recall that 1.5m is the same as 150cm.
Now, we simply build a proportion where we consider 48 to be 100, and wonder what 150 will be:
Solving for x, we have
Which actually makes sense, because we're stating that 1.5m is about 300% of 48cm, which means three times as much. Which is true, because three times 48cm means 144cm, which is about 1.5m
