Answer:

About 157.5 inches

Step-by-step explanation:

Let's break it down. We know there are 12 inches in a foot and there are about 3.281 feet in a meter.

Now, let's see how many feet are in 4 meter. To do that we are going to multiply the number of feet in one meter times four. So, 4 × 3.281, that equals 13.124.

Now, let's see how many inches are in 13.124 feet. To do that we will multiply the number of inches in one foot times 13.124. So, 13.124 × 12, that equals 157.488.

We can round that to 157.5 inches.

Jessie works at a car manufacturing plant. One day she installed a total of 46 axles, 2 in each car she worked on. She wants to

shtirl [24]

Answer:

Step-by-step explanation:

total number of cars: x

the total number of axles: 46

and the number of axles installed per car: 2

2 axles in each car, then total instaled axles: 2•x

2•x = 46

x = 46÷2

x = 23

2) Find the area and perimeter of a semi -circular disc whose radius is 10cm. (take π = 3.14)

SVETLANKA909090 [29]

Answer:

=3.14×10x10

=3.14×100cm2

=3.14cm2

<h3>Perimeter = 2 pi r</h3>

=2 ×3.14×10

=6.28cm

Or =Pi d

= 3.14 ×20cm

=62.8cm

R means radius

D means diameter

radius is half of a diameter e.g radius is10 and diameter is 20

A standard piece of paper is 0.05 mm thick. Let's imagine taking a piece of paper and folding the paper in half multiple times.

tatyana61 [14]

Answer:

(a) $g(n)=0.05\cdot 2^n$

(b) $g^{-1}(n)=\log_{2}20g(n)$

Step-by-step explanation:

The paper's thickness = 0.05mm

When the paper is folded, its width doubles (increases by 100%).

The thickness of the paper grows exponentially and can be modeled by the function:

$g(n)=0.05(1+100\%)^n\\\\g(n)=0.05\cdot 2^n$

<u /> $g(n)=0.05\cdot 2^n\\2^n=\dfrac{g(n)}{0.05}\\ 2^n=20g(n)\\$Changing to logarithm form, we have:\\\log_{2}20g(n)=n\\$Therefore:\\g^{-1}(n)=\log_{2}20g(n)$ <u />

<u />

If the thickness of the paper, g(n)=384,472,300,000 mm

Then:

$g^{-1}(n)=\log_{2}20g(n)\\g^{-1}(n)=\log_{2}20\times 384,472,300,000\\=\dfrac{\log 20\times 384,472,300,000}{\log 2} \\g^{-1}(n)=42.8 \approx 43\\n=43$

You must fold the paper 43 times to make the folded paper have a thickness that is the same as the distance from the earth to the moon.
