¿Cuál es el valor de la razón de cambio cuando tenemos un vaso con agua a temperatura ambiente al congelador por 15 minutos?

grandymaker [24]

Answer: $2 \°C/min$

Step-by-step explanation:

The rate of change is a measure in which one variable is modified in relation to another. In this case we have the variables:

Temperature in $\°C$

Time in $min$

Now, to calculate the rate of change, we have to divide one variable by the other. In this case the change in temperature $\Delta T$ divided by the time variation $\Delta t$ .

Hence, assuming the ambient temperature of the glass is $30 \°C$ and the elapsed time $15 min$ we have:

$\frac{\Delta T}{\Delta t}=\frac{30 \°C}{15 min}=2 \frac{\°C}{min}$

Which word problem matches the problem? 2 3 x 7 A) Mark has 7 gallons of milk. Ernesto drinks 2 3 of a gallon. How much milk is

kakasveta [241]

Answer:

Out of given word problem , (B) word problem matches the given problem.

B) Mark drinks $\frac{2}{3}$ of a gallon of milk every week. How much does he drink in 7 weeks? written as,

$x=\frac{2}{3}\times 7$

Step-by-step explanation:

Given problem $\frac{2}{3} \times 7$

We are given four options and we have to chose the correct one.

We will convert each given statement into mathematical problem.

Consider,

A)Mark has 7 gallons of milk. Ernesto drinks $\frac{2}{3}$ of a gallon. How much milk is left?

Mathematically represented as,

Let left milk be x then ,

$x=7-\frac{2}{3}$

B)Mark drinks $\frac{2}{3}$ of a gallon of milk every week. How much does he drink in 7 weeks?

Mathematically represented as,

Let milk drink by Mark in 7 weeks be x gallons then ,

$x=\frac{2}{3}\times 7$

C) Mark has $\frac{2}{3}$ of a gallon of milk. Ernesto has 7 gallons of milk. How much do they have together?

Mathematically represented as,

Let they together they drink x gallon milk, then

$x=\frac{2}{3}+ 7$

D) Mark has $\frac{2}{3}$ of a gallon of milk to divide among 7 family members. How much milk does each person get?

Mathematically represented as,

Let each person gets x gallon milk, then

$x=\frac{2}{3} \div 7$

Thus, out of given word problem , (B) word problem matches the given problem
