Answer:
Step-by-step explanation:
m<ARL and m<LRB together equal 180 degress.
x=37.4
So 2(37.4)-5 is
m<LRB=69.8
Answer:
40
Step-by-step explanation:
you have to do this first:
10x4=40
Answer:
This predicted value is that it is unrealistically high
Step-by-step explanation:
According to the data given in order to calculate the predicted value we would have to make the following calculation of the predicted value and then conclude.
predicted value=26.693 + 0.055*3000
predicted value=191.693
By having the result of the predicted value we can conclude that what is wrong about this predicted value is that it is unrealistically high.
Answer:
It'll take 12 minutes to be at 30 degrees.
Step-by-step explanation:
Since the metal is cooling at a linear rate then the rate of degrees per minute should be the through the cooling process. From 4 minutes to 7 minutes there was a span of 3 minutes and in that time the metal cooled 105 degrees. So the metal is cooling at a rate of
rate = 105/3 degrees/minute = 35 degrees/min
To reach 30 degrees from 205 it should cool down an additional 175 degrees so it'll take:
minutes = deegrees/rate = 175/(35) = 5 minutes
Since the metal had a temperature of 205 degrees in 7 minutes, then it'll take 12 minutes to be at 30 degrees.
There would be 5184 ways in which each subject books can be selected.
<u>Explanation:</u>
Number of geography books = 5
Number of chemistry books = 4
Number of Science books = 7
Different ways of selecting geography books = 5!
= 5 X 4 X 3 X 2 X 1
= 120
Different ways of selecting chemistry books = 4!
= 4 X 3 X 2 X 1
= 24
Different ways of selecting Science books = 7!
= 7 X 6 X 5 X 4 X 3 X 2 X 1
= 5040
Total different possible ways they can select them = 120 + 24 + 5040
= 5184
