Using proportions, it is found that it takes 3.5 \times 10^{23} meter sticks to equal the mass of the moon.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, one meter stick has a mass of 0.2 kg. How many meter sticks are needed for a mass of 7 \times 10^{22} \text{kg}? The <em>rule of three</em> is given by:

One meter stick - 0.2 kg

x meter sticks - 7 \times 10^{22} \text{kg}

Applying cross multiplication:

0.2x = 7 \times 10^{22}

x = \frac{7 \times 10^{22}}{0.2}

x = 35 \times 10^{22}

x = 3.5 \times 10^{23}

It takes 3.5 \times 10^{23} meter sticks to equal the mass of the moon.

How many times greater is the value of 5 in 3,590 than the value of 5 in 359 ?
Tresset [83]

Answer:

10 times greater is the value of 5 in 3,590 than the value of 5 in 359.

Step-by-step explanation:

To find : How many times greater is the value of 5 in 3,590 than the value of 5 in 359 ?

Solution :

The place value stem is

Thousand     Hundred     Tens    Ones

  1000               100            10         1

The value of 5 in 3,590 is at hundred place

So, 5\times 100=500

The value of 5 in 359 is at tens place

So, 5\times 10=50

Number of time greater is the value of 5 in 3,590 than the value of 5 in 359 is given by,

n=\frac{500}{50}

n=10

Therefore, 10 times greater is the value of 5 in 3,590 than the value of 5 in 359.

How do u find this??????????????????????/
Zielflug [23.3K]
The question is asking you to find the slope. Slope intercept form is writen:
y = mx + b    (m being the slope and b being the y-intercept)

The slope would be 5 and the y-intercept would be 0.

So, your answer would be y = 5x also known as C. y = 5x

Hope I helped! :)

Alenkinab [10]

Answer:

C(s) = 6s^2 + \dfrac{1500}{s}\\\text{where s is the side of base.}

Step-by-step explanation:

We are given the following in the question:

A storage shed is to be built in the shape of a (closed) box with a square base.

Volume = 150 cubic feet

Let s be the edge of square base and h be the height.

Volume of cuboid =

l\times b\times h

where l is the length, b is the base and h is the height.

Volume of box =

s^2h = 150\\\\h = \dfrac{150}{s^2}

Area of base =

\text{side}\times \text{side} = s^2

Cost of concrete for the base = $4

Cost of base($) = 4s^2

Area of roof =

\text{side}\times \text{side} = s^2

Cost of material for the roof = $2

Cost of roof ($) = 2s^2

Area of 4 walls =

4\times (sh)\\=4sh

Cost of material for the side = $2.50

Cost of material of side($) =

2.50\times 4s(\dfrac{150}{s^2})\\\\=\dfrac{1500}{s}

Total cost

= Cost of base + Cost of 4 sides + Cost of roof

C(s) = 4s^2 + \dfrac{1500}{s} + 2s^2\\\\C(s) = 6s^2 + \dfrac{1500}{s}

is the required cost function.
