A rectangle initially has width 7 meters and length 10 meters and is expanding so that the area increases at a rate of 8 square

Tems11 [23]

Answer:

The length of rectangular is increasing at a rate 0.5714 meters per hour.

Step-by-step explanation:

We are given the following in the question:

Initial dimensions of rectangular box:

Length,l = 10 m

Width,w = 7 m

$\dfrac{dA}{dt} = 8\text{ square meters per hour}\\\\\dfrac{dw}{dt} = 40\text{ centimeters per hour} =0.4\text{ meters per hour}$

We have to find the rate of increase of length.

Area of rectangle =

$A = l\times w$

Differentiating we get,

$\displaystyle\frac{dA}{dt} = \frac{dl}{dt}w + \frac{dw}{dt}l$

Putting values, we get,

$8 = \dfrac{dl}{dt}(7) + (0.4)(10)\\\\\dfrac{dl}{dt}(7) = 8 -4\\\\\dfrac{dl}{dt} \approx 0.5714$

Thus, the length of rectangular is increasing at a rate 0.5714 meters per hour.

An art club is going to a museum. Six adults are going. 18 more kids than adults are going. Adults tickets cost $24 each, which

dybincka [34]

so their are 6 adults and 24 kids because when you add 18+6 and get 24

then you multiply 6(24) because adult tickets are 24 and get 144

then you multiply 24(12) because student tickets are half as much as parents so they are 12 and you multiply by 24 kids and get 288

then you add 288 student tickets total price +144 adult ticket total price =432 total cost fro all tickets
