Answer:
- NQ = 3π units
- sector area = 9π square units
- 24 +3π units
Step-by-step explanation:
The formulas tell you for a circle of radius 6, ...
C = 2π(6) = 12π
A = πr² = π(6²) = 36π
__
a)
Arc NQ is 1/4 of the circumference of the circle, so will have length ...
NQ = 1/4C = 1/4(12π)
NQ = 3π . . . . units
__
b) Each sector is 1/4 the area of the circle. The area of one sector is ...
sector area = 1/4A = 1/4(36π)
sector area = 9π . . . . square units
__
c) The total path length is equal to the sum of the lengths of the pieces of the path length. Each radius is 6 units.
PRQNP = PR +RQ +QN +NP
= PR +RQ +QN +NR +RP
= 6 +6 +3π +6 +6
path length = 24 +3π . . . . units
__
Numerical answers (rounded to hundredths):
NQ ≈ 9.42 u
area ≈ 28.27 u²
PRQNP = 33.42 u
Answer:
Step-by-step explanation:
Let the number of mysteries solved=x, then according to question, number of mysteries Evan solved=
, also together they solve all the mysteries, thus
Thus, total number of mysteries solved=63.
Also, total number of mysteries Evan solved=
.
Answer: a
adding the two polynomials will give you the answer a
Answer:
You can’t make it the same, but you can make it almost the same.
Maggie would have to rent 4 movies to make the plans’ cost almost the same.
Explanation:
$150-$129= 21
21 divided by 5= 4.2 (You can’t rent 4.2 movies, so we go with 4)
4x5=20+$129= $149 (Almost $150)
So, Maggie would have to rent 4 movies to make the costs almost the same.
Hope this is helpful!!
P.S Sorry if there was another way to make the costs equal, I’m not the best at math!
:D
