Answer:
Step-by-step explanation:
we know that
If the central angle of the circle is 90 degrees, then the sector will have an area equal to one quarter of the whole circle.
so
we have
----> the radius is half the diameter
substitute
Answer:
r=5
Step-by-step explanation:
1.simplify both sides of the equation.
2.substract 2r from both sides.
3.substract 12 from both sides.
4.multiply both sides by 5/(11)
5. your answer will be 5.
r=5
Answer:
$2,400
Step-by-step explanation:
Note: The correct years is 4 not 44
The Principal = $10,000
Time period = 4 years
Rate = 6 % p.a.
Simple Interest = Principal * Rate * Time
Simple Interest = $10,000 * 6% * 44
Simple Interest = $2,400
So, the amount of interest Diego earned after four years is $2,400
When y increases, x increases ⇒ Direct
y = kx
when y = 9, x =3
9 = k(3)
9 = 3k
k = 3
therefore y = 3x
