Answer: d = ±10
<u>Step-by-step explanation:</u>
169 =
+ ![(\frac{d}{2})^{2}](https://tex.z-dn.net/?f=%28%5Cfrac%7Bd%7D%7B2%7D%29%5E%7B2%7D)
169 = (12)² + ![\frac{d^{2}}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5E%7B2%7D%7D%7B4%7D)
169 = 144 + ![\frac{d^{2}}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5E%7B2%7D%7D%7B4%7D)
25 = ![\frac{d^{2}}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5E%7B2%7D%7D%7B4%7D)
100 = d²
√100 = √d²
±10 = d

Answer:
![0.9](https://tex.z-dn.net/?f=0.9)
Step-by-step explanation:
![\text{Absolute value is always positive. So,}\\\\|-0.9| = 0.9](https://tex.z-dn.net/?f=%5Ctext%7BAbsolute%20value%20is%20always%20positive.%20So%2C%7D%5C%5C%5C%5C%7C-0.9%7C%20%3D%200.9)
Answer:
The answer is the same as the explanation
Step-by-step explanation:
First at point B create a line that is the distance of AB that stops at C and make sure the angle on the inside is 90 degrees and then do the same with A to point D. Then connect point C and D making a perfect square.
Answer:
100 miles
Step-by-step explanation:
Given :
To work :
speed = 50mph
Let time taken = x
From work :
speed = 40mph
30 minutes = 30/60 = 0.5
Time taken = x + 0.5
Distance from home to work :
Distance = speed * time
To work distance = from work distance
This can be algebraically expressed as :
50 * x = 40(x + 0.5)
50x = 40x + 20
50x - 40x = 20
10x = 20
x = 20/10
x = 2
Hence,
Distance = 50 * 2 = 100
The the distance from home to work = 100 miles
