y = √z^2 - x^2
=> z = √x^2 + y^2
Answer: $101.25
Step-by-step explanation:
Since we are given the information that one metre of ribbon costs $0.45 and that Tabitha buys 225 metres of ribbon, the amount that she will have to pay will be gotten by multiplying the cost of one meter of ribbon by the total meters that she bought. This will be:
= $0.45 × 225
= $101.25
Therefore, the cost is $101.25

Answer:
19,8
105,7
144,84
304
Step-by-step explanation:
At first, 9) is not correct.
Formula for surface of parallelogram is
A=a*H
DONt divide with 2.
So the 9) is 19.8
10) A=15.1*7=105.7
11) A=14.2*10.2=144.84
12) A=20*15.2=304
