Step-by-step explanation:
357-200 is 157 extra minutes (we are only counting the extra minutes)
157*0.25 is 39.25 (this is how much is the extra minutes in total cost)
therefore, add 39.25 and 29.99
29.99+39.25 is 62.24
Therefore, the total bill was $62.24
hope this helps :)
Have a nice day !

Answer:
- 32.823 kJ
- 190.4 kJ
- 260.00 kJ
- 180.012 kJ
Step-by-step explanation:
The conversion factor for food energy or thermochemical calorimetry* is ...
1 calorie = 4.184 J
1000 calorie = 4.184 kJ
__
a. 7845 cal = 7845·4.184 J = 32,823 J = 32.823 kJ
b. 4.55·10^4 cal = 4.55·10^4·4.184 J = 1.904·10^5 J = 190.4 kJ
c. 62.142 kcal = 62.142·4.184 kJ = 260.00 kJ
d. 43,024 cal = 43,024·4.184 J = 180,012 J = 180.012 kJ
_____
* The thermochemical calorie is defined in terms of the heat capacity of water. An international calorie of 4.1868 J is defined in terms of energy, without respect to the heat capacity of water.
60x0.25=15
60x0.10=6
51x0.25=12.75
13.35-12.75

Q-51
Answer:
L= 11
Step-by-step explanation:
Formula to find the length when you know the area:
L = A/W
So the equation for this one is:
L = 93 1/2 ÷ 8 1/2
Simplify:
L = 11
To be sure of your answer you multiply the L x W = A
11 x 8 1/2 = 93 1/2
Hope this helped : D
