Answer:
37
Step-by-step explanation:
To find the average, you need to add all the numbers in the set and divide that value by the total amount of numbers there are,
We already know that the average of the set of temperatures is 40,
Since there are 5 different days with temperatures, multiply 40 by 5,
40 × 5
= 200
200 is what all the temperatures should equal once they are added up,
Now add 40, 39, 44, and 40 together,
40 + 39 + 44 + 40
= 163
Now subtract 163 from 200,
200 - 163
= 37
Therefore the temperature that was recorded on the fifth day was 37f.
Binomial theorem:
The
term corresponds with the term in the sum for which
. For this
, we get
So the coefficient you want to find is
Answer:
B: 1344cm^2
Step-by-step explanation:
calculate the total area of each shape and add it together
J(Jane) + 3 = B(Billy)*2
J + 3 = 7(2)
J + 3 = 14
J = 14-3
J = 11 (Jane is 11)Cheers!
Answer:
see explanation
Step-by-step explanation:
(16)
The mid segment ZW is half the sum of the parallel bases
ZW = = = 29
(17)
The lower base angles are congruent , so
∠ UYX = ∠ VXY = 35°
(18)
Any lower base angle is supplementary to any upper base angle , then
∠ VUY = 180° - ∠ UYX = 180° - 35° = 145°
(19)
= ZW
= 10 ( multiply both sides by 2 to clear the fraction )
10x = 20 ( divide both sides by 10 )
x = 2
Then
XY = 7x + 1 = 7(2) + 1 = 14 + 1 = 15
(20)
The legs are congruent , so
UY = VX
5a - 6 = 3a + 2 ( subtract 3a from both sides )
2a - 6 = 2 ( add 6 to both sides )
2a = 8 ( divide both sides by 2 )
a = 4
