The area of the trapizoif is 97.5
Answer:
1530cm
Step-by-step explanation:
First figure (9x10)x9=810
Second figure (18x10)x4=720
720+810=1530
Answer:
All you have to do is combine the like terms. Once you do that you get: -4x+3y=-11
Answer: Yes the win level is greater than 1/2
Step-by-step explanation: 32/52 is greater than 1/2
The irrational numbers are: √8, √10 and √15
Step-by-step explanation:
A rational number is a number that can be written in the form p/q where p&q are integers and q≠0.
"All the numbers whose square root is not a whole number and has an infinite number of digits after decimal, are irrational numbers"
So in the given options
![\sqrt{4} = 2](https://tex.z-dn.net/?f=%5Csqrt%7B4%7D%20%3D%202)
Which can be written in the required form so √4 is a rational number
![\sqrt{8}=2.828427124746190097603.....](https://tex.z-dn.net/?f=%5Csqrt%7B8%7D%3D2.828427124746190097603.....)
√8 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number
![\sqrt{10}=3.16227766016837933....](https://tex.z-dn.net/?f=%5Csqrt%7B10%7D%3D3.16227766016837933....)
√10 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number
![\sqrt{15}=3.87298334620.....](https://tex.z-dn.net/?f=%5Csqrt%7B15%7D%3D3.87298334620.....)
√15 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number
![\sqrt{36} = 6](https://tex.z-dn.net/?f=%5Csqrt%7B36%7D%20%3D%206)
Which can be written in the required form so √36 is a rational number
Hence,
The irrational numbers are: √8, √10 and √15
