2. About 40 millions of aluminum cans can be recycled each month in the US. A quarter of these aluminum cans are used to make on

geniusboy [140]

Answer:

48

Step-by-step explanation:

About 40 millions of aluminum cans can be recycled each month in the US. A quarter of these aluminum cans are used to make one aluminum boat. How many aluminum boats can be made in one year in the US?

Given that:

Approximate Number of cans that can be recycled per month in the US = 40 million

Fraction of recycled cans that can be used to make an aluminum boat = 1/4

The number of aluminum boats that can be made in the US in one year :

If about 40 million cans are recycle per month :

The number of boat that can be made from each monthly recycled aluminum cans will be :

Number of monthly recycled can needed to make one boat:

1/4 * 40 million = 10 million cans

Hence, 40,000,000 / 10,000,000 = 4

4 aluminum boats can be made in one month :

Number of months in a year = 12

Number of aluminum boats that can be made in a year :

4 per month * 12 = 48 aluminum boats

A pyramid shaped building is 311 feet tall and has a square base with sides of 619 ft. The sides of the building are made from r

zmey [24]

Answer:

Surface area of the reflective glass is 543234.4 square feet.

Step-by-step explanation:

Given that: height = 311 feet, sides of square base = 619 feet.

To determine the slant height, we have;

$l^{2}$ = $311^{2}$ + $309.5^{2}$

= 96721 + 95790.25

= 192511.25

⇒ l = $\sqrt{192511.25}$

= 438.761

The slant height, l is 438.8 feet.

Considering one reflecting surface of the pyramid, its area = $\frac{1}{2}$ × base × height

area = $\frac{1}{2}$ × 619 × 438.8

= 135808.6

= 135808.6 square feet

Since the pyramid has four reflective surfaces,

surface area of the reflective glass = 4 × 135808.6

= 543234.4 square feet

Please help with #5 and #8! I don’t really know all of the info to find the volume! (Composite Figures)

bagirrra123 [75]

It looks like you're doing good with breaking-down the composite into digestible pieces. So, don't stress too much!

Keep in mind that the area for a 3D shape is Bh, where "B" is the area of a face & "h" is the height.

#5
Shape A is 3X4X9.
First, calculate the area of a face:

9X4= 36

Multiply by height:

36X3= 108

The process is the same with shape B.
3X4X8
Calculate area of face:

8X4= 32

Multiply by height:

32X3= 96

Now you add both areas:

108+96= 204 cubic feet

I think you're doing pretty good, just don't over think things too much. Try #8 with the similar process seen here. Just comment if you get stuck.

Hope this helps!
