Answer:
A) ∠AOB = 36°
Step-by-step explanation:
The full circle area = 10²π or 100π
the shaded portion is (10π/100π)(360°) = 36°
Answer:
260%
Step-by-step explanation:
For the coffee;
cost price (
) = $5/kg
selling price (
) = $18/kg
Percentage profit (%P) =
%
Substitute the right values into the above;
%P =
%
%P =
%
%P = 260%
Therefore, the percentage profit compared to the original cost of the coffee is 260%
Answer:
See explanation
Step-by-step explanation:
∠POR is congruent to ∠VOE because they are vertical angles
∠PRV is congruent to ∠RVE because alternate interior angles are congruent when the lines are parallel.
VO is congruent to OR which is given
Therefore, ΔPRO is congruent to ΔEVO by the angle-side-angle theorem
So, PR is congruent to VE because corresponding parts of congruent triangles are congruent
We know what every year has 365 but once every four years has 366. We can simplify it by saying that every year has 365 and 1/4 days
Now, we just have to mulitiply

So we can say that 50 years have 18262 days and chance to 18263 (depends when we started counting)
