Answer:
(a) 
(b)The boiling point of water in Celsius scale is 100°C.
(c)The setting in Celsius scale is 26.7°C.
Step-by-step explanation:
Given that,the formula is
......(1)
(a)
Given that,
[ subtracting 32 from both sides]
......(2) [Multiplying 
]
(b)
Given that, the boiling point of water is 212°F.
Putting F=212 in equation (2)
The boiling point of water is 100°C.
(c)
Given that, a house thermostat is set at 80 degree.
Putting F=80 in equation (2)
The setting in Celsius scale is 26.7°C.
It's D, 3-2i.
Hope this helps
Answer:
es 8
Step-by-step explanation:
Step-by-step explanation:
5.
angle STQ is the supplementary angle (together they are 180° below line MQ) to 2x + 8.
above ST we have a group of 3 angles that combine to 180° :
2x + 8
90°
71 - x
so, to get x first :
2x + 8 + 90 + 71 - x = 180
x + 169 = 180
x = 11
so, the angle MTS =
2x + 8 = 2×11 + 8 = 22 + 8 = 30°.
6.
therefore, the angle STQ is
180 - angle MTS = 180 - 30 = 150°.
