Answer:
AE=22.4
Step-by-step explanation:
BE is 1/2 of BC
BC is 20 cm All sides of a square are equal
BE = 1/2 BC Property of a midpoint.
BE = 10
Now just use Pythagorus
AB^2 + BE^2 = AE^2
AE^2 = 20^2 + 10^2 Perform the sqrs
AE^2 = 400 + 100 Add the terms
AE^2 = 500 Take the square root of both sides
√AE^2 = √500
AE = 22.36
AE ≈ 22.4
Answer:
every pair is being multi by the next number
Step-by-step explanation:
2 x 3 =6
3 x 4 = 12 so the second number goes up one every time
Add, divide- turn division equation into a fraction, boom
For this case, the first thing you should do is take into account the irrational number definition.
An irrational number is one that can not be written as the quotient between two whole numbers.
Their number of decimals is unlimited and they are not periodic.
An irrational number within the specified domain is:
π/2 = 1.570796327
Answer:
an example of an irrational number that is less than 2 and greater than 1.5 is:
π/2 = 1.570796327
A = length x width
15,000 = (w + 30) x w
15,000 =
![w^{2}](https://tex.z-dn.net/?f=%20w%5E%7B2%7D%20)
+ 30w
0 =
![w^{2}](https://tex.z-dn.net/?f=%20w%5E%7B2%7D%20)
+ 30w - 15,000
Use quadratic formula to find that w= -15 + or - 5
![\sqrt{609}](https://tex.z-dn.net/?f=%20%5Csqrt%7B609%7D%20)
. Because distance cannot be negative, the width is -15 + 5
![\sqrt{609}](https://tex.z-dn.net/?f=%20%5Csqrt%7B609%7D%20)
meters or approximately 108.39 meters. This means that the length is approximately 138.39 meters.
