Answer: ![24\ ft](https://tex.z-dn.net/?f=24%5C%20ft)
Step-by-step explanation:
Given
The slant height of the square pyramid is ![l=25\ ft](https://tex.z-dn.net/?f=l%3D25%5C%20ft)
The length of the side of the base is ![a=14\ ft](https://tex.z-dn.net/?f=a%3D14%5C%20ft)
for the square pyramid, height is given by
![\Rightarrow h=\sqrt{l^2-r^2}\quad \quad [\text{where r=}\frac{a}{2}]\\\Rightarrow h=\sqrt{25^2-7^2}\\\Rightarrow h=\sqrt{625-49}\\\Rightarrow h=\sqrt{576}\\\Rightarrow h=24\ ft](https://tex.z-dn.net/?f=%5CRightarrow%20h%3D%5Csqrt%7Bl%5E2-r%5E2%7D%5Cquad%20%5Cquad%20%5B%5Ctext%7Bwhere%20r%3D%7D%5Cfrac%7Ba%7D%7B2%7D%5D%5C%5C%5CRightarrow%20h%3D%5Csqrt%7B25%5E2-7%5E2%7D%5C%5C%5CRightarrow%20h%3D%5Csqrt%7B625-49%7D%5C%5C%5CRightarrow%20h%3D%5Csqrt%7B576%7D%5C%5C%5CRightarrow%20h%3D24%5C%20ft)
Thus, the height of the prism is
If you were rounding the exact answer 'could' be 499,999 or it 'could' be 455,555. But it would be difficult to know the definitive amount, so basically anything above 450,000.
Hello!
Robin can clean 72 rooms in 6 days. How many rooms can Robin clean in 9 days?
We have a proportional magnitude (directly proportional), if we increase the number of days for cleaning, obviously we will have more rooms cleaned, then:
clean rooms __________ days
72 ----------------------------------- 6
y ------------------------------------- 9
![\dfrac{72}{y} = \dfrac{6}{9}](https://tex.z-dn.net/?f=%5Cdfrac%7B72%7D%7By%7D%20%3D%20%5Cdfrac%7B6%7D%7B9%7D)
multiply the means by the extremes
![6*y = 72*9](https://tex.z-dn.net/?f=6%2Ay%20%3D%2072%2A9)
![6\:y = 648](https://tex.z-dn.net/?f=6%5C%3Ay%20%3D%20648)
![y = \dfrac{648}{6}](https://tex.z-dn.net/?f=y%20%3D%20%5Cdfrac%7B648%7D%7B6%7D)
![\boxed{\boxed{y = 108}}\Longleftarrow(clean\:rooms)\end{array}}\qquad\checkmark](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cboxed%7By%20%3D%20108%7D%7D%5CLongleftarrow%28clean%5C%3Arooms%29%5Cend%7Barray%7D%7D%5Cqquad%5Ccheckmark)
Answer:
108 clean rooms in 9 days

Answer:
6.58 x 10^-3
Explanation:
Moving the decimal place till it’s in front of the 6
See how if the number (1-4 u would round down, 5-9 u round up) u would look at the place value it asks then look at the one next to it and see if u round up of down so it would be 17.3
