Answer:
7650 W-h
Step-by-step explanation:
1 day = 24 hrs
4 days and 6 hours = 4(24) + 6 = 102 hours
given
24 hrs (i.e 1 day) ------> consumes 1800 W-h
1 hour ------> consumes 1800/ 24 = 75 W-h
102 hrs (i.e 4 days 6 hrs) = 75 W-h x 102 = 7650 W-h
Hey there!!
Let us take the price of cinnamon tea as ' x ' and spice tea as ' y '
Now, let us take it into equation
12x + 3y = 15 -------------- ( 1 )
14x + 12y = 45 --------------- ( 2 )
Let us multiply the first equation with 4
48x + 12y = 60 --------------- ( 1 )
14x + 12y = 45 --------------- ( 2 )
Now, subtract equation 2
48x + 12y = 60
-14x - 12y = -45
Now, we get,
34x = 15
x = 15 / 34
This is the cost for cinnamon tea = $ 15 / 34
Now, substitute this into one equation
Let us take this equation - 12x + 3y = 15
Now, substitute ' x '
12 ( 15 / 34 ) + 3y = 15
6 ( 15 / 17 ) + 3y = 15
90 / 17 + 3y = 15
3y = 15 - 90/17
3y = 165 / 17
y = ( 165/17 ) ( 1 / 3 )
y = $ 55/17
Cinnamon tea = $ 15/34
Spice tea = $ 55/17
Hope helps!
To find the average, divide change in weight by change in weeks.
(149-134)/(8-13)
You should get a negative number, because he loses weight.
Answer:
13
Step-by-step explanation:
Since x is squared, the inverse operation would be square root. So, the square root of 169 is 13.
