Answer:
$22.50
Step-by-step explanation:
Let's write what we know.
$10 a month bonus
+ $0.50 / per item of the month
$2 per compliment
We can write an equation:
T = Total bonus for the month
i = number of item of the month sales
c = number of compliments
T = $10 + $0.50i + $2c
i = 17
c = 2
Plug in the values:
T = $10 + $0.50i + $2c
T = $10 + $0.50( 17 )+ $2( 2 )
T = $10 + $8.50 + 4
T = $22.50
Her bonus for this month is $22.50
Do 72 divided by 6 to get 12 so the answer is D
When you multiply exponents you have to add them so that means
Answer:
The required specific heat is 196.94 joule per kg per °C
Step-by-step explanation:
Given as :
The heat generated = Q = 85.87 J
Mass of substance (m)= 34.8 gram = 0.0348 kg
Change in temperature = T2 - T1 = 34.29°C - 21.76°C = 12.53°C
Let the specific heat = S
Now we know that
Heat = Mass × specific heat × change in temperature
Or, Q = msΔt
Or, 85.87 = (0.0348 kg ) × S × 12.53°C
Or , 85.87 = 0.4360 × S
Or, S =
∴ S = 196.94 joule per kg per °C
Hence the required specific heat is 196.94 joule per kg per °C Answer
