Change of rate<span>. If the unit or quantity in respect of which something is changing is not specified, usually the rate is </span>per unit of measurement<span>. However, a rate of change can be specified per unit of </span>time<span>, or per unit of </span>length<span> or </span>mass<span> or another quantity. The most common type of rate is "per unit of time", such as </span>speed<span>, </span>heart rate<span> and </span>flux<span>.</span>

James bought 5 1/6pounds of grapes for $7.75. At theunit rate, how much would 3.4 pounds of grapes cost?

frutty [35]

Answer:

Explanation:

5 1/6 pounds of graphs are bought for $7.75, meaning 1 pound costs

$\frac{7.75\text{ dollars}}{5\frac{1}{6}lb}$

And we need to compute the division above.

The first step is to convert the mixed number 5 1/6 into an improper fraction.

Now, it is true that

$5\frac{1}{6}=5+\frac{1}{6}$

multiplying 5 by 6/6 gives

$5\cdot\frac{6}{6}+\frac{1}{6}$ $\frac{30}{6}+\frac{1}{6}$

The temperature of a piece of Metal X with a mass of 95.4g increases from 25.0°C to 48.0°C as the metal absorbs 849 J of heat. W

Nataly_w [17]

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.

If 3t − 7 = 5t , then 6t = how do you solve this

Alik [6]

$3t-7=5t \ \ \ |\hbox{subtract 3t} \\ -7=5t-3t \\ -7=2t \ \ \ |\hbox{multiply by 3} \\ \boxed{6t=-21}}$
