Penelope jogs three laps around the playground to keep in shape. The playground is rectangular with width of 163 m and a length

antoniya [11.8K]

The total amount of meters in one lap is 966 m

<h3>Further explanation</h3>

To solve the above questions, we need to recall some of the formulas as follows:

Area of Rectangle = Length × Width

Perimeter of Rectangle = 2 × ( Length + Width )

<em>Let us now tackle the problem !</em>

$\texttt{ }$

<u>Given:</u>

Length of Rectangle = L = 320 m

Width of Rectangle = W = 163 m

<u>Unknown:</u>

Perimeter of Rectangle = P = ?

<u>Solution:</u>

This problem is about Perimeter of Rectangle.

<em>The total amount of meters in one lap is equal to the perimeter of playground.</em>

<em>Let's find the perimeter of Rectangle.</em>

$\texttt{Perimeter of Rectangle} = 2 (\texttt{Length} + \texttt{Width})$

$P = 2 ( L + W )$

$P = 2 ( 320 + 163 )$

$P = 2 ( 483 )$

$P = \boxed {966 ~ \texttt{m}}$

$\texttt{ }$

<h2>Conclusion:</h2>

The total amount of meters in one lap is 966 meters

Researchers counted and tagged 638 deer. On their next visit, they counted 105; only 35 were marked. Estimate the total deer pop

Vedmedyk [2.9K]

Answer:

1914

Step-by-step explanation:

Let the estimated total population of the deer =x

Out of x, 638 were tagged.

Out of 105, 35 were marked.

Expressing this as a ratio of the total to tagged, we have:

x:638=105:35

$\dfrac{x}{638}=\dfrac{105}{35} \\$Cross Multiply\\35x=105*638\\x=(105*638)\div 35\\x=1914$

Therefore, the total deer population in the area is approximately 1,914.

Mary's car will go 261 miles on 14.5 gallons of gasoline in highway driving.

suter [353]

Answer:

a) 91 1/6 gallons

b) 2502 miles

Step-by-step explanation:

You are given a number of miles and a number of gallons for the car. The ratio of these numbers is ...

(261 mi)/(14.5 gal) = 18 mi/gal

We presume this value is constant for this car. Then the questions can be answered by forming and solving a proportion:

a) 1641 miles/(gallons) = 18 mi/(1 gal)

Multiplying by gallons and dividing by 18 mi/gal, we get

1641/18 gal = (gallons) = 91 1/6 gal

It will take 91 1/6 gallons of gasoline for Mary to drive to her friend's house.

___

b) Same deal, but the miles are unknown.

(miles)/(139 gal) = (18 mi)/(1 gal)

Multiplying by 139 gal gives ...

(18 mi)·139 = (miles) = 2502 mi

139 gallons of gasoline will let Mary drive 2502 miles.
