Answer:
b
Step-by-step explanation:
Justin's score has to be greater than 80. the appropriate inequality sign is >
Note that
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
On the number line, since the score has to be greater than 80, the line would start from 80 and end on 95
> or < is represented by unfilled circle
≤ or ≥ is represented by filled circle
Answer:
![\huge\boxed{x=28\ ft}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7Bx%3D28%5C%20ft%7D)
Step-by-step explanation:
If two rectangles are similar, then corresponding sides are in proportion.
Therefore we have the equation:
![\dfrac{x}{42}=\dfrac{36}{54}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%7D%7B42%7D%3D%5Cdfrac%7B36%7D%7B54%7D)
cross multiply
![54x=(42)(36)\\\\54x=1512](https://tex.z-dn.net/?f=54x%3D%2842%29%2836%29%5C%5C%5C%5C54x%3D1512)
divide both sides by 54
![\dfrac{54x}{54}=\dfrac{15212}{54}\\\\x=28](https://tex.z-dn.net/?f=%5Cdfrac%7B54x%7D%7B54%7D%3D%5Cdfrac%7B15212%7D%7B54%7D%5C%5C%5C%5Cx%3D28)
The correct option is "d".
Given that L = 0.8T²
length of pendulum = 30ft
L= 0.8T²
30 = 0.8T²
T² = 30 / 0.8
T² = 37.5
T = √37.5 = 6.1 seconds
<span>So, 6.1 is the closest to the period in seconds for a pendulum that is 30 ft long.</span>
It can't be factored because there are no 2 numbers that when you multiply you get 35 and when you add you get 13.
8*4
I hope that helps !
So, 4*4*4*4 = 16+16 which is 32
