David is making baskets of fruit he has 12 apples and 20 pears what is the greatest number of baskets he can make

He can make 12 baskets i’m pretty sure because if he only has 12 apples you have to put the same with the pears if that makes sense

The sum of two numbers is 40. The second number is 5 less than twice the first number. Let x represent the first number and let

SashulF [63]

Step-by-step explanation:

x+y=40

y=2x-5

$x = 40 - y \\ y = 2(40 - y) -5 \\ y = 80 - 2y - 5 \\ 3y = 75 \\ y =25 \\ x = 40 - y \\ x = 15$

A cylindrical tank has a radius of 4 m and a height of 10 m. The tank is filled with water. Find the work needed to pump the top

Gekata [30.6K]

Answer:

$w=2.216*10^{6} J$

Step-by-step explanation:

Data:

r=4m

h=10m

w=? (3 m of water out top of the tank)

g=9.8m/s2

б=1000kg/m3

We must find the work necessary to move 3m of water from the top of the tank, so there is a differential (dy) that represents a small portion of volume for which it is integrated for the total volume to move then it would be the weight for the distance that is the volume to move

dw=weight*(10-y)dy, weight=б*V, , ⇒ weight=б*Vdy*g ⇒ dw=16πg(10-y)dy ⇒

$w=16\alpha \pi g(10y-\frac{y^{2}}{2})$ evaluated between a and b, but a=10 and b=7 (last 3m of the full tank), finally

$w=16\alpha \pi g((100-50)-(70-24.5))\\w=16\alpha \pi g(4.5)=72\alpha \pi g\\w=2.126*10^{6}J$
