Answer:
i. RP = 17
ii. RT = 15
iii. RS = 30
Step-by-step explanation:
Given that; QT = 9 and TP = 8.
From the diagram, join R to P. Thus RP = QP (radius of the circle)
RP = QT + TP
= 9 + 8
RP = 17
Applying Pythagoras theorem to triangle TRP;
RT = 
= 
= 
= 15
∴ RT = 15
But, RT = TS = 15.
So that;
RS = 15 + 15
= 30
RS = 30
Therefore; RP = 17, RT = 15 and RS = 30.

Answer:
Final answer is 
.
Step-by-step explanation:
Given expression is 
.
Now we need to smplify the given expression .
So begin with factoring 20 into two parts so that one part is perfect square number.
Hence final answer is .
The expression that lists all numbers in prime numbers would be A. All numbers here are prime numbers, and is in the simplified form, the remaining choices are not in their simplified forms and can be broken down into smaller numbers that multiply to give their value.
If y = 0.75 when x = 0.5, set up a proportion -
0.75:0.5
x:3
Since you have to multiply 0.5 by 6 to get 3, multiply 0.75 by 6 to get your answer: y = 4.5 when x = 3.
