Mr. Smith has 15.6 pounds of oranges to pack for shipment. He can ship 2.4 pounds of oranges in a large box and 1.2 pounds in a

s2008m [1.1K]

Answer:

3 boxes.

Step-by-step explanation:

Let x represent number of 1.2 pounds boxes.

We have been given that Mr. Smith has 15.6 pounds of oranges to pack for shipment. He can ship 2.4 pounds of oranges in a large box and 1.2 pounds in a small box.

The oranges covered in x small boxes would be $1.2x$

Oranges packed in 5 large boxes would be $5\times 2.4\text{ pounds}=12\text{ pounds}$ .

We can represent our given information in an equation as:

$1.2x+12=15.6$

$1.2x+12-12=15.6-12$

$1.2x=3.6$

$\frac{1.2x}{1.2}=\frac{3.6}{1.2}$

$x=3$

Therefore, the minimum number of small boxes required to ship the rest of the oranges would be 3 boxes.

The base of a solid is the region in the first quadrant between the graph of y=x2 and the x -axis for 0≤x≤1 . For the solid, eac

nata0808 [166]

Answer:

The volume of the solid is π/40 cubic units.

Step-by-step explanation:

Please refer to the graph below.

Recall that the area of a semi-circle is given by:

$\displaystyle A=\frac{1}{2}\pi r^2$

The volume of the solid will be the integral from x = 0 to x = 1 of area A. Since the diameter is given by y, then the radius is y/2. Hence, the volume of the solid is:

$\displaystyle V=\int_0^1\frac{1}{2}\pi \left(\frac{y}{2}\right)^2\, dx$

Substitute:

$\displaystyle V=\frac{1}{2}\pi\int_0^1\left(\frac{x^2}{2}\right)^2\, dx$

Simplify:

$\displaystyle V=\frac{1}{2}\pi \int_0^1\frac{x^4}{4}\, dx$

Integrate:

$\displaystyle V=\frac{1}{2}\pi \left[\frac{x^5}{20}\Big|_0^1\right]$

Evaluate:

$\displaystyle V=\frac{\pi}{40}\left((1)^5-\left(0\right)^5\right)=\frac{\pi}{40}\text{ units}^3$

The volume of the solid is π/40 cubic units.

Review the graph of complex number z.

vredina [299]

Answer:

$6\sqrt{2} (\cos(135^{\circ})+i\sin(135^{\circ}))$

Step-by-step explanation:

The angle to the point in the second quadrant is measured from the positive real axis (the x-axis). Second quadrant angles are between 90° and 180°, leaving the 135° choices as the only ones that make sense.

The magnitude of z is the root of the sum of the squares of its components:

|z| = √((-6)^2 +6^2) = 6√2

So, the polar form of z is ...

$\boxed{6\sqrt{2} (\cos(135^{\circ})+i\sin(135^{\circ}))}$

this matches the first choice
