Setler [38]3 years ago
7 0
We find the length of AD using the similarity of right triangle property. See image attached.

AD² = BD × CD
AD² = 9 × 36
AD² = 324
AD² = 18²
AD = 18

The length of AD is 18 units

Answer:

15 x^8 y^3

Step-by-step explanation:

The area of a rectangle is given by

A = l*w  where l is the length and w is the width

A = ( 5x^6 y^2) *( 3x^2 y)

   = 15 x^(6+2) y^(2+1)

   = 15 x^8 y^3

At noon joyce drove to the lake at 30 mph, but she made the long walk back home at 4 mph. how many hours did she walk if she was
lina2011 [118]
By definition we have the following equation:
 t = d / v
 Where,
 t: time
 d: distance
 v: speed
 For this case we have:
 d / 30 + d / 4 = 17
 Rewriting we have:
 2d + 15d = 17 (60)
 17d = 17 (60)
 d = 60 mi
 Then, the walking time is
 t = d / v
 t = 60/4
 t = 15 hours
 Answer:
 
She walked
 
t = 15 hours

The mean length of 10 childrens' index finger is 12.6cm.
ICE Princess25 [194]

Get total lengths by multiplying:

10 x 12.6 = 126

6 x 16.1 = 96.6

Add the total lengths together and divide by 16:

126 + 96.6 = 222.6


222.6 / 16 = 13.9125

Rounded to 2 decimal places = 13.91


answer: 13.91
