A liquid at temperature 7575F is placed in an oven at temperature 450450. The temperature of the liquid increases at a rate 77 t

hichkok12 [17]

Answer: $\dfrac{dT(t)}{dt}=77\times (450-T)$

Step-by-step explanation:

Given

The temperature of the liquid is $75^{\circ}F$ placed in an oven with temperature of $450^{\circ}F$ .

Initially difference in temperature of the two

$\Delta T=450-75\\\Rightarrow \Delta T=375^{\circ}F$

According to the question

$\Rightarrow \dfrac{dT(t)}{dt}=77\cdot \Delta T\\\\\Rightarrow \dfrac{dT(t)}{dt}=77\times (450-T)\quad [\text{T=75}^{\circ}F\ \text{at t=0}]$

I need help with this

Andre45 [30]

Answer:

3 pairs for the price of two.

Step-by-step explanation:

$10 per pair

3 x 2

then:

3 pairs costs $20

20/3 = $6.6667 each pair

Buy one and get 25% of the second

25% = 25/100 = 0.25

then:

first pair $10

second pair: 10 - (10*0.25) = 10 - 2.5 = $7.5

first + second pair = 10 + 7.5 = 17.5

2 pairs costs $17.5

17.5/2 = $8.75 each pair

then:

the best deal:

3 pairs for the price of two.
