Answer:
A) 6^2 + 11^2 is not equal to 15^2
Step-by-step explanation:
To find out if a right triangle is a right triangle you have to use the Pythagorean Theorem, like it is used in A.
6^2 + 11^2 = 15^2
36 + 121 = 225
157 does not equal 225
So this is not a right triangle
(3,2) is the answer of the system of equations.
Answer:
It would take more than 16 weeks to drop below freezing.
Step-by-step explanation:
The temperature is dropping from 96°F to 32°F at a rate of 4°F per week, where 32°F is the freezing point.
Hence, 32 = 96 - 4w { Where w week is required to reach 32°F }
⇒ 4w = 64
⇒ w = 16
Therefore, it would take more than 16 weeks to drop below freezing. ( Answer )
