Answer: option b
Step-by-step explanation:
Answer: 123.5 centimeters
Step-by-step explanation:
Let sum of observations be S and number of observations be n.
Average A=
The average height of 4 children is (15h-3)

Also, when two more children join the group with heights of (10h+46) centimeters and (14h-16) centimeters the sum of heights of 6 children will be

Now, Average height of 6 students=
At h=9
Average height of 6 students=
Answer:
4.5 + 4.5 + 7.5 + 3 + 9 + 4.5 = 33 is the perimeter of the first shape
The area is (4.5 x 7.5) + (3 x 9) = 60.75
(Cut the figure)
Perimeter of the Second Shape is:
22 + 22 + 10 + 10 = 64
Area is: 22 x 10 = 220
Area of a parallelogram is: L x W
Answer:
I got 320 but what does the 121 mean?
Step-by-step explanation:
<u><em>PEMDAS</em></u>
<u><em>72- 33</em></u>
<u><em>40</em></u>
<u><em>40 x 8 </em></u>
<u><em>320</em></u>
<u><em>There 320 is your answer</em></u>
Have a nice day :)
May God Bless you
I just answered a so let's start with b :
______________________________
b. The equivalent resistance of series
resistances is equal to their sum
Thus :
equivalent resistance = 480 + 360
equivalent resistance = 840
_______________________________
c.
I = V ÷ R
I = 120 ÷ 840
I = 0.1428 A
_______________________________
d. 0.1428 A
_______________________________
e. 480 ===》 120 - ( 480 × 0.1428 ) =
120 - 68.544 =
51.456
360 ===》 120 - ( 360 × 0.1428 ) =
120 - 51.408 =
68.592
_______________________________
f. 480 ===》68.544 lower than battery
360 ===》 51.408 lower than battery
