Select each equation which is equivalent to 60% of 25.

Maksim231197 [3]

The equation which is equivalent to 60% of 25 is x = 0.6 * 25

An equation is used to show the relationship between variables, numbers.

Let x represent the value of 60% of 25. Hence:

x = 60% of 25

x = 0.6 * 25

Hence the equation which is equivalent to 60% of 25 is x = 0.6 * 25

x/25 = 60/100

6/10 = x/25

At the moment a hot cake is put in a cooler, the difference between the cake's and the cooler's temperatures is 50\degree50°50,

Len [333]

Answer:

$D(t)=50\cdot (0.8)^{t}$

Step-by-step explanation:

The equation for exponential decay function is given as:

$D(t)=a(1-r)^{t}$

where:

D(t)= difference in temperature t=time

r=rate of change

a =initial value of the temperature

From the given problem:

Initial Temperature,a=50°C

Rate of Decay,r= $\frac{1}{5}$

Therefore the function for the difference in temperature is given as:

$D(t)=50(1-\frac{1}{5})^{t}$

$D(t)=50\cdot (\frac{4}{5})^{t}$

We can convert $\frac{4}{5}$ to decimal and write the function as:

$D(t)=50\cdot (0.8)^{t}$
