Answer:

Step-by-step explanation:

Divide the figure into a rectangle and a triangle.

area of rectangle = 5×10 = 50 square units

area of triangle = 0.5×5×10 = 25 square units

total area = 50+25 = 75 square units

One conveyor belt can move 1000 boxes in 9 minutes. Another can move 1000 boxes in 11 minutes. If another conveyor belt is added

Ugo [173]

Answer:

It would take 7.62 minutes for the third conveyor belt alone to do the same job

Step-by-step explanation:

The together rate is the sum of each separate rate.

In this question:

First conveyor: Rate of 1/9.

Second: Rate of 1/11.

Third: Rate of 1/x.

Total: 1/3

$\frac{1}{9} + \frac{1}{11} + \frac{1}{x} = \frac{1}{3}$

$\frac{11x + 9x + 99}{99x} = \frac{1}{3}$

$\frac{20x + 99}{99x} = \frac{1}{3}$

$3(20x + 99) = 99x$

$60x + 297 = 99x$

$39x = 297$

$x = \frac{297}{39}$

$x = 7.62$

It would take 7.62 minutes for the third conveyor belt alone to do the same job

Can someone please explain how to do these?

Answer:

First question answer: The limit is 69

Second question answer: The limit is 5

Step-by-step explanation:

For the first limit, plug in $x=8$ in the expression $(9x-3)$ , that's the answer for linear equations and limits.

So we have:

$9x-3\\9(8)-3\\72-3\\69$

The answer is 69

For the second limit, if we do same thing as the first, we will get division by 0. Also indeterminate form, 0 divided by 0. Thus we would think that the limit does not exist. But if we do some algebra, we can easily simplify it and thus plug in the value $x=1$ into the simplified expression to get the correct answer. Shown below:

$\frac{x^2+8x-9}{x^2-1}\\\frac{(x+9)(x-1)}{(x-1)(x+1)}\\\frac{x+9}{x+1}$

Now putting 1 in $x$ gives us the limit:

$\frac{x+9}{x+1}\\\frac{1+9}{1+1}=\frac{10}{2}=5$

So the answer is 5
