Josh wants to determine the number of loaves of bread he can bake using the 13 and one-third cups of flour he has. If each loaf
motikmotik

Answer:

Approximately 4 loaves of bread.

Step-by-step explanation:

Let us get out the total amount of flour that Josh has first of all. This is 13\frac{1}{3} cups of flour.

Each lof requires 3\frac{4}{5} cups of flour. This means that to make a loaf, he will be taking out this quantity of flour from the whole lot.

To get the total number of loaves he can make with this quantity of flour, we will have to divide the total quantity of flour available by the quantity required to make a single loaf.

This will be 13\frac{1}{3} ÷3\frac{4}{5} = 3\frac{29}{57} . This is approximately 4 loaves of bread

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}
