Answer:

c = 0.38 J/g °C

Step-by-step explanation:

We have,

Mass of metal X is 95.4 g

Initial temperature was 25°C and final temperature is 48°C.

The metal absorbs 849 J of heat

The heat absorbed due to change in temperature is given by :

Q=mc\Delta T\\\\c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{849}{95.4\times (48-25)}\\\\c= 0.38\ J/g^{\circ} C

So, the specific heat of metal X is 0.38 J/g °C.

Liula [17]

Always know the formula for volume prism because that shape is a prism.

Formula For PRISM: BH/2 x Height.

So then we are going to solve the triangle first... 7 x 22= 154/2= 77

Then multiply by the height which is 25.

77 x 25= 1,925.

So your answer should be 1,925 meters cubed. *Don't forget to write the measurement

goldenfox [79]

Answer:

Choice C: 6.23

Step-by-step explanation:

\frac{5}{100} = \frac{x}{124.50} -----> cross multiply

5(124.50) = 100x

622.5 = 100x

\frac{622.5}{100} = \frac{100x}{100}

6.225 = x

6.225 rounded to the nearest hundredth is 6.23

She earned 6.23 commission.
