Answer:
The path length is the same for the small and large semicircles.
Step-by-step explanation:
The distance around the large semicircle = 1/2 * π * diameter
= 1/2*8*π
= 4π m.
The distance around the 2 smaller semicircles
= 1/2 * 4 * π + 1/2 * 4 * π
= 2π + 2π
= 4π m.
The altitude of the right triangle is the geometric mean of the 2 parts of the side it separates.
a. The answer would be sqrt(18*32)=24
The question to the second question can be answered by using the Pythagorean theorem.
32^2+24^2=1600=40^2
b. The answer would be sqrt40^2=40
<span>Let +a+ = number of trumpet players
Let +b+ = number of saxophone players
---------------------
(1) +a+=+b+-+10+
(2) +b+=+3a+
----------------
Substitute (2) into (1)
(1) +a+=+3a+-+10+
(1) +2a+=+10+
(1) +a+=+5+
and
(2) +b+=+3%2A5+
(2) +b+=+15+
------------------
There are 5 trumpet players
and 15 saxophone players</span>
Answer:
y axis grows side to side I think
Answer:
C) 7 and 3
Step-by-step explanation:
2x+4+8x-10=x²+15
10x-6=x²+15
0=x²-10x+21
0=(x-3)(x-7)
x=3 and 7
