Find out the length of each side. For the slanty sides, you can do this by using the formula

$d = \sqrt{(y2-y1)^{2} +(x2-x1)^{2} }$

For the straight sides (like the one on the bottom and the one on the left), just use simple subtraction.

Add up all 4 sides and you get the perimeter. You should get 20, 15, $5\sqrt{5}$ and $5\sqrt{26}$ . The total is 35 + $5(\sqrt{26} +\sqrt{5} )$ .

Answer:

2141.76 cubic inches

Step-by-step explanation:

Given that it measures 8.8 inches across a properly inflated basketball i.e. the diameter of each basketball is 8.8 inches.

So, the radius of the spherical ball is $\frac{8.8}{2} =4.4$ inches.

Now, a spherical solid has a volume given by $\frac{4}{3} \pi r^{3}$ .

Hence, volume of air in side each basketball is = $\frac{4}{3} \times \frac{22}{7}\times 4.4^{3} = 356.96$ cubic inches.

Therefore, the total volume of air inside six balls will be = 6 × 356.96 = 2141.76 cubic inches. (Answer)

In a scale drawing, a building has a length of 15 cm. The actual length of the building is 37.5 feet. Whats the scale of the dra

Feliz [49]

Answer:

$\frac{15}{37.5}\ \frac{cm}{ft}$

$1.31:100$

Step-by-step explanation:

we know that

The scale of the drawing is equal to divide the length of a building in the scale drawing by the actual length of a building

$\frac{15}{37.5}\ \frac{cm}{ft}$

That means

15 cm in the drawing represent 37.5 ft in the actual

Remember that

$1\ ft=30.48\ cm$

Convert 15 cm to ft

divide by 30.48

$15\ cm=15/30.48\ ft$

substitute

$\frac{15}{37.5}\ \frac{cm}{ft}=\frac{(15/30.48)}{37.5}=\frac{0.0131}{1}$

$1.31:100$

That means

1.31 units in the drawing represent 100 units in the actual

Generate the first 5 terms of this sequence:

AURORKA [14]

<span>We are given f(1) = 0 and f(2) = 1. Going forward, the term is the sum of the two previous terms. f(3) = f(2) + f(1) = 0 + 1 = 1. f(4) = f(3) + f(2) = 1 + 1 = 2 f(5) = f(4) + f(3) = 2 + 1 = 3 This matches answer B.</span>
