Answer:  Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Number of miles the Baldwin family walked is given by

\frac{4}{5}\ miles

Number of hours the Baldwin family walked is given by

\frac{4}{9}\ hour

So, we need to find the unit rate in miles per hour.

Speed=\frac{Distance}{time}\\\\Speed=\frac{\frac{4}{5}}{\frac{4}{9}}\\\\Speed=\frac{9}{5}=1\frac{4}{5}\ mph

Hence, Option 'B' is correct.

How can i solve it formula y= mx + b
Serjik [45]

Answer:

y = 4/3x - 4

Step-by-step explanation:

you are given b

so y = mx -4

you can look at the graph and see the slope from there. like the y-intercept and the x-intercept

(0,-4) and (3,0)

slope formula is y2-y1/x2-x1

and so you do -4-0/0-3

-4/-3.

so your slope formula would be

y = 4/3x - 4

<u>To find the density:</u>

 ⇒ must find the relationship between the density, mass, and volume

    ⇒ Density = \frac{mass}{volume}

<u>Let's examine the information given:</u>

  • weight: 1890g
  • dimensions: 8cm * 5cm* 5cm

<u>Let's first find the volume:</u>

   ⇒ the volume is the dimensions multiplied together

      Volume = 8cm * 5cm * 5cm = 200cm^3

<u>LEt's calculate the density now:</u>

  Density = \frac{1890g}{200cm^3} =9.45g/cm^3

<u>Answer:</u> The density of the copper is <u>9.45g/cm^3</u> or <u>Choice (A)</u>

<u></u>

Hope that helps!

The force F of gravity on a rocket varies directly with its mass m and inversely with the square of its distance d from Earth. W
xz_007 [3.2K]

Model for the Combined variation  is  F = \frac{km}{d^{2} }

Equation to find the mass of the rocket in terms of F and d is :

m=\frac{F d^{2} }{k}

<h3>What is Force ?</h3>

A force is the quantity that change the motion of the object. Force is that influence which can cause any object having some mass, to change it's position or to accelerate from it's original position.

Force (F) and mass (m) of any object are  directly proportional to each other. More the mass of the object , more the force will require to accelerate it.

Mathematically, we can write the equation of force as :

F = m . a

where , m = mass of the object

             a = constant value

In the statement given,

As, force of gravity varies directly with its mass

Therefore, F= k m , where k is a constant

Also force is inversely varies with square of distance d

Thus, F = k / d²

Combining both equations :

F = \frac{km}{d^{2} }  

and the equation of mass in terms of F and d can be written as :

m=\frac{F d^{2} }{k}
