The density of a certain material is such that it weighs 4 kilograms

per cubic foot of volume. Express this density in ounces per cubic

meter. Round your answer to the nearest whole number.

Answers

Answer:

4986 ounces/m³

Step-by-step explanation:

1 kilogram = 35.274 ounces

1 cubic foot = 0.0283 cubic metre

We are converting kg/ft³ to ounces/m³

Hence:

4kg/ft³ × 35.274 ounces/ 1 kg × 1 ft³/0.0283m³

= 4985.7243816 ounces/m³

Approximately to the nearest whole number = 4986 ounces/m³

Translation and rotation

Step-by-step explanation:

"Translation" simply means Moving without rotating, resizing or anything else, just moving.

A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction. You can turn a figure 90°, a quarter turn, either clockwise or counterclockwise. When you spin the figure exactly halfway, you have rotated it 180°. Turning it all the way around rotates the figure 360°.

For a craft project, four students each chose three pieces of wire from a box. Don's wires measure 3 inches, 5 inches, and 12 inches. Margo's wires measure 6 inches, 8 inches, and 14 inches. Sonji's wires measure 12 inches, 8 inches, and 17 inches. Liam's wires measure 16 inches, 8 inches, and 27 inches.

Answers

Answer:

Sonji's wires measure will be chosen

Step-by-step explanation:

Given:

Don's wires measure = 3 inches, 5 inches, and 12 inches

Margo's wires measure = 6 inches, 8 inches, and 14 inches

Sonji's wires measure = 12 inches, 8 inches, and 17 inches

Liam's wires measure = 16 inches, 8 inches, and 27 inches.

Find:

Measure used to construct a triangle

Computation:

In a triangle sum of two smaller side is grater then bigger side

a + b > c

So.

Don's wires measure = 3 inches + 5 inches < 12 inches

Margo's wires measure = 6 inches + 8 inches = 14 inches

Sonji's wires measure = 12 inches + 8 inches > 17 inches

Liam's wires measure = 16 inches + 8 inches < 27 inches.

So,

Sonji's wires measure will be chosen

The height, hh, of a plant (in inches) ww weeks since it was planted is represented by the equation h=1.2w+3h=1.2w+3. How many weeks ( round up to the nearest whole number) will it take the plant to reach one foot? ( Hint: convert feet to inches.) Answer value

Answers

Answer:

It will take 8 weeks for the plant to reach one foot.

Step-by-step explanation:

The equation is:

[tex] h = 1.2w + 3 [/tex]

Where:

h: is the height = 1 foot

w: is the time in weeks =?

We can convert feet to inches as follows:

[tex] 1 feet = 12 inches [/tex]

[tex] h = 1 ft*\frac{12 in}{1 ft} = 12 in [/tex]

Hence, the number of weeks is:

[tex] w = \frac{h - 3}{1.2} = \frac{12 - 3}{1.2} = 7.5 = 8 [/tex]

Therefore, it will take 8 weeks for the plant to reach one foot.
