The area of a rectangle is 105 square units. Its width measures 7 units. Find the length of its diagonal. Round to the nearest t
mezya [45]

Answer:

16.6

Step-by-step explanation:

The rectangle has an area of 105. It's width is 7.

1: Find the length

     \frac{area}{width}=length

     \frac{105}{7}= 15

      Length=15

2: Pythagorean theorem

      a^{2} +b^2=c^2

       7^{2}+15^2=c^2

       49+225=c^2

        275=c^2

         \sqrt{275} = \sqrt{c^2\\}

          16.55≈c

           Rounded to nearest tenth

              16.6

P/2 = 3/4 + p/3 solve for p<br> Show your work<br> It is URGENT
il63 [147K]

Step-by-step explanation:

p/2 = 3/4 + p/3

p/2 - p/3 = 3/4

(3p - 2p )/6 = 3/4

p/6 = 3/4

multiply both sides by 6

p = 3×6/4

=18/4

=9/2

=4.5
