Answer:

It will take Lainey 9 seconds to travel from top to bottom

Further explanation:

The formula of speed will be used to calculate the time to reach from top to bottom of the slide.

Given

\begin{gathered}Distance=d=423\ feet\\Speed=s=47\ feet\ per\ second\end{gathered}

Distance=d=423 feet

Speed=s=47 feet per second

The formula for speed is:

s=\frac{d}{t}s=

t

d

Putting the values of distance and speed in the formula:

\begin{gathered}47=\frac{423}{t}\\t=\frac{423}{47}\\t=9\ seconds\end{gathered}

47=

t

423

t=

47

423

t=9 seconds

It will take Lainey 9 seconds to travel from top to bottom

2. Maria is monitoring the temperature of
stiks02 [169]

Here, we are required to determine after how many minutes will the two substances be at the same temperature.

The equation of when the two substances will be at the same temperature and the solution are as follows;

(a) The equation is 96.2 + 1.5(x) = 98.5 + 0.8(x).

(b) The solution is, x = 3.285minutes.

For substance A which is currently at 96.2° and rising at 1.5° each minute; It's temperature after x minutes is given as;

  • T(a) = 96.2 + 1.5(x)

For substance B which is currently at 98.5° and rising at 0.8° each minute; It's temperature after x minutes is given as;

  • T(b) = 98.5 + 0.8(x)

(a) For the two substances to be at the same temperature; T(a) must be equal to T(b).

  • T(a) = T(b)

The equation is therefore;.

96.2 + 1.5(x) = 98.5 + 0.8(x)

(b) To determine the solution;

1.5x - 0.8x = 98.5 - 96.2

0.7x = 2.3

x = 2.3/0.7

x = 3.285minutes.

What is 7.8×10^5 hours in days?
iragen [17]

Answer:

32500 Days

Step-by-step explanation:

7.8 × 10^{5} = 780000

We know that there are 24 hours in a day.

⇒24 Hours = 1 Day

therefore 780000 hours = \frac{780000}{24} = 32500 Days

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}
