A square lawn has an area of 1152 square feet. A sprinkler placed at the center of the lawn sprays a water in a circular pattern

oksano4ka [1.4K]

Answer:

The radius of the circle is 16.97 feet

Step-by-step explanation:

First, we will the determine the length of one the sides of the square lawn.

From the question,

The square lawn has an area of 1152 square feet,

Now, we can determine the length of a side of the square lawn from the formula,

$A = l^{2}$ ( Formula for Area of a square)

Where $A$ is the area of the square lawn

and $l$ is the length of a side of the square lawn

From the question, $A$ = 1152 square fee

Then,

$1152 = l^{2}$

$l^{2} = 1152\\l = \sqrt{1152}$

$l = 24\sqrt{2}$ feet or $33.94$ feet

This is the length of one of the sides of the square lawn.

From the description in the question, the sprinkler sprays water in a circular pattern that just covers the lawn,

If the circular pattern formed just covers the lawn,

then, the diameter of the circle equals the length of one of the sides of the square lawn, that is,

$l = d$

Where $d$ is the diameter of the circle

Hence, $d = 24\sqrt{2}$ feet

This is the diameter of the circle.

Now, for the radius of the circle,

From the relation between radius and diameter,

$Radius = \frac{Diameter}{2}$

Then,

$Radius = \frac{24\sqrt{2} }{2}$

$Radius = 12\sqrt{2}$ feet or $16.97$ feet

Hence, the radius of the circle is 16.97 feet

We can use the formula density mass over volume to find the density of a substance square metal plate has a density of 10.7 g of

sweet-ann [11.9K]

Answer: The volume of given substance is $2.2 cm^{3}$ .

Step-by-step explanation:

Given: Density = 10.7 $g/cm^{3}$

Mass = 23.54 g

Density of a substance is the mass of substance divided by its volume.

Mathematically, $Density = \frac{mass}{volume}$

Substitute the values into above formula to calculate volume as follows.

$Density = \frac{mass}{volume}\\10.7 g/cm^{3} = \frac{23.54 g}{volume}\\volume = \frac{23.54 g}{10.7 g/cm^{3}}\\= 2.2 cm^{3}$

Thus, we can conclude that the volume of given substance is $2.2 cm^{3}$ .

A pizza delivery worker purchased a used motor scooter that had been driven 12{,}10012,100 miles. He drives the motor scooter on

In-s [12.5K]

Answer:

$25,000=50d+12,100$

Step-by-step explanation:

Let d represent the number of pizza delivery days.

We have been given that a pizza delivery worker drives the motor scooter only on days he is working, during which he drives an average of 50 miles per day. So the number of miles driven in d days will be 50d.

As the delivery worker purchased a used motor scooter that had been driven 12,100 miles. This means that initial value or y-intercept will be 12,100.

$\text{Total number of miles the scooter has been driven}=\text{Miles driven in d days+Initial value}$

Upon substituting our given values we will get,

$25,000=50d+12,100$

Therefore, the equation $25,000=50d+12,100$ models the total number of miles driven in d days of pizza delivery.
