Answer: The first one.
Step-by-step explanation:
One circle has a 96 cm diameter
and another circle has a 295.16 cm circumference.
Which has a larger radius?
Radius of the first circle is 48 cm.
Radius of the second circle is 47 cm
The first circle has a larger radius.
Answer:
45 minutes
Step-by-step explanation:
let after t hours they meet after the second runner starts.
15 minutes=1/4 hour.
6(t+1/4)=8t
6t+6/4=8t
8t-6t=6/4
2t=3/2
t=3/2* 1/2=3/4 hours=45 minutes
Answer:
Step-by-step explanation:
Let 
y=2x-10
Switch x and y,
x=2y-10
x+10=2y
(x/2)+5=y
So 
Answer:
This is a reflection about the x-axis.
Step-by-step explanation:
A reflection about the x-axis has the rule
[x,y]-> [x,-y].
Therefore
M[x,y] = [x,-y}
Let M=
|a b|
|c d|
Then the matrix multiplication gives
ax+by=x.............(1)
cx+dy=-y............(2)
Solving the previous equations (1) and (2) gives
a=1, b=0
c=0, d=-1
giving M as
|1 0|
|0 -1|
