Answer:

30 miles

Step-by-step explanation:

Before finding the perimeter of the given right angled triangle, we need to find the length of a.

We'll be using pythagoras property to find the value of a.

According to the pythagoras property, sum of the squares of base and perpendicular is equivalent to the square of hypotenuse.

Here,

  • Hypotenuse = 13 mi
  • Base = 12 mi
  • Perpendicular (a) = ?

→ H² = B² + P²

→ H² - B² = P²

→ (13 mi)² - (12 mi)² = a²

→ 169 mi² - 144 mi² = a²

→ 25 mi² = a²

→ √(25 mi²) = a

→ <u>5 mi = a</u>

We know that,

  • Perimeter of ∆ = Sum of all sides

→ Perimeter = 13 mi + 12 mi + a

→ Perimeter = 13 mi + 12 mi + 5 mi

→ Perimeter = 30 miles

\therefore <u>Perimete</u><u>r</u><u> </u><u>of</u><u> </u><u>the </u><u>triangle</u><u> </u><u>is</u><u> </u><u>3</u><u>0</u><u> </u><u>mi</u><u>l</u><u>e</u><u>s</u><u>.</u>

It is recommended that there be at least 15.9 square feet of ground space in a garden for every newly planted shrub. A garden is
NISA [10]
The maximum number of shrubs (x) = a(area) divided by 15.9

a(area)=37.1*15
37.1*15= 556.5
556.5/15.9=x
556.5/15.9=35
35=x

Uber charges 1.75 for pickup plus 0.50 per mile. Omar paid 4.25 for a ride. How many miles did he travel?
Sergeu [11.5K]

Answer:

Omar Traveled 5 miles

Step-by-step explanation:

First set up a two step equation, .50x (x is our variable for miles driven) then +1.75= 4.25. Then Subtract 1.75 from itself and from 4.25. You get 2.5, bring everything down. You are now left with .50x=2.5 divide each side by .50 . 2.5 divided by .50 equals 5 and .50 divided by itself is zero, bring down the x and the 2.5. It should now look like this x = 2.5 That is your answer.
