If the perimeter of triangle ABC is 4 more than the perimeter of triangle ACD, what is the perimeter of quadrilateral ABCD? AD i
melisa1 [442]

Answer:

26 units.

Step-by-step explanation:

AB + BC + AC = AC + AD + DC + 4

AC is common so

AB + BC = AD + DC + 4

AB + BC - AD - DC = 4

Substituting the given values

AB + 7 - 5 - 6 = 4

AB = 4 - 7 + 5 + 6 =  8

So the perimeter of ABCD

= AB + BC + AD + CD

= 8 + 7 + 5 + 6

= 26.

Help me llliad plz neeeeeeed help
Lapatulllka [165]
Lets get started :)

Diameter = 2.5 ft
Radius = \frac{diameter}{2} = \frac{2.5}{2} = 1.25

a) The Circumference formula of a circle is given in the picture below, we can plug-in the given information

C = 2\pi(1.25) or 2.5\pi
    ≈ 7.85 ft 
(we can leave the answer in terms of pi {\pi})

b) We divide the total number of distance the tire will travel by the circumference to find how many times the tire will roll

\frac{5280}{circumference} = \frac{5280}{2.5 \pi } 
(I have used the value in feet because we found the circumference in feet units and notice that I took the value of circumference to be 2.5\pi instead of 7.85, to increase accuracy)

672.2

The tire will rotate 672 times (a tire cannot roll a decimal times, so we take to the nearest whole number) to travel 1 mile
