Mathematics

Answer

Just remember to divide the diameter by two to get the radius.

Step-by-step explanation:

If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation

Rashid [163]

Answer:

John work as a security guard job <u>27 hours</u> and as a landscaper <u>33 hours</u>.

Step-by-step explanation:

Given:

John works two jobs.

As a security guard he earns $8.50 per hour and as a landscaper he earns $14 per hour.

One week John worked a total of 60 hours and earned $691.50.

Now, to find hours he work at each job.

Let the job of security guard be x hours.

And the job of landscaper be y hours.

So, the total hours John worked in a week:

x+y=60.

⇒ y=60-x.............( 1 )

<em>Now, the money earned by John in a week:</em>

8.50x+14y=691.50

<em>Putting the equation ( 1 ) in the place of y:</em>

⇒ 8.50x+14(60-x)=691.50

⇒ 8.50x+840-14x=691.50

<em>Moving variables on one side and the other we get:</em>

⇒ 840-691.50=14 x-8.50x

⇒148.50=5.50x

<em>Dividing both sides by 5.50 we get:</em>

⇒ 27=x

<u>As a security guard job he worked 27 hours</u><u>.</u>

Putting the value of in x equation ( 1 ) we get:

y=60-27

⇒ y=33.

<u>As a landscaper he worked 33 hours</u>.

Therefore, John work as a security guard job 27 hours and as a landscaper 33 hours.

Cole wants to buy carpet to cover his whole living room, except for the tiled floor. The tiled floor is 4 5 6 ft by 2 1 3 ft. Fi
Shtirlitz [24]

Answer:

Area = 49\frac{25}{36}

Step-by-step explanation:

Given

Tile

Length = 4\frac{5}{6}

Width = 2\frac{1}{3}

See attachment for dimension of the floor

Required

Determine the area covered by the carpet

From the attachment, the dimension of the floor is:

Length = 12\frac{1}{4}

Width = 5

Calculate Area

Area = Length * Width

Area = 12\frac{1}{4} * 5

Area = 61\frac{1}{4}

The area of the tiles is:

Area = 4\frac{5}{6} * 2\frac{1}{3}

Area = \frac{29}{6} * \frac{7}{3}

Area = \frac{203}{18}

Area = 11\frac{5}{18}

So, the carpet area is:

Area = Floor\ Area - Tile\ Area

Area = 61\frac{1}{4} - 11\frac{5}{18}

To improper number

Area = \frac{245}{4} - \frac{208}{18}

Take LCM

Area = \frac{2205 - 416}{36}

Area = \frac{1789}{36}

Area = 49\frac{25}{36}
