The double number line below shows the approximate number of pounds in a certain number of kilograms: Two number lines are shown

one above the other. The number line on the bottom shows three longer vertical lines. Between each longer vertical line there is a shorter vertical line. There is one shorter vertical line after the last longer vertical line. There by making a total of three shorter vertical lines. The longer vertical lines are labeled 3, 5, 7. On the right of this number line is written Pounds. The number line above it also has three longer vertical lines and three shorter vertical lines. The first longer vertical line is ahead of the first longer vertical line of the bottom number line so that the first shorter vertical line on the top number line is aligned with the first longer vertical line, labeled 3 on the bottom number line. The second longer vertical line is ahead of the second longer vertical line of the bottom number line so that the second shorter vertical line on the top number line is aligned with the second longer vertical line, labeled 5, on the bottom number line. The third longer vertical line is ahead of the third longer vertical line of the bottom number line so that the third shorter vertical line on the top number line is aligned with the third longer vertical line, labeled 7, on the bottom number line. The longer vertical lines on the top number line are labeled 1, 2, 3, respectively. On the right of this number line is written Kilograms. Based on the number line, about how many pounds are there in 4.5 kilograms? 8 9 10 11

How do you find the area of a regular polygon?
Bogdan [553]
Each of the triangles are equal in base length, height, and area<span>. Remember the formula for the </span>area<span> of a triangle. The </span>area<span> of any triangle is 1/2 times the length of the base (which, in the </span>polygon<span>, is the length of a side) multiplied by the height (which is the same as the apothem in </span>regular polygon<span>).

How much carbon dioxide will you prevent from entering the atmosphere in one year, if you replace a 100-watt light bulb with a C
Afina-wow [57]

Answer:

280000lb

Step-by-step explanation:

In this question, we shall be calculating the amount of carbon iv oxide prevented from entering the atmosphere.

Generally we know that 1kwh produces 1.37 lbs of Carbon iv oxide in the atmosphere

Now, using a 100 watt light bulb daily for 8 hours, for a year, the amount of Carbon iv oxide produced will be;

100 * 1.37 * 8 * 365 = 40040 lb

Using a 30 watt CFL for 8hrs/ day for a year, we have;

30 * 1.37 * 8 * 365 = 120012 lb

Now calculating the amount of CO2 prevented, we have 40040 - 120012 = 280028 lb = 280000 after rounding up

Find the volume of the rectangular prism.<br> 19 cm<br> 9 cm<br> 2 cm
Makovka662 [10]

Answer: 342 cm³

Step-by-step explanation: To find the volume of the rectangular prism, start with the formula for the volume or a prism.

Volume = length × width × height

Since we are not sure what the length, width, or height is in this problem, we can plug any of these numbers in for the length, width, or height. The commutative property of multiplication states that changing the order of the factors does not change the product.

Volume = (19 cm) (9 cm) (2 cm)

Volume = 342 cm³

Therefore, the volume of the rectangular prism is 342 cm³.
