Answer:
Step-by-step explanation:
It is assumed the rectangular prism with dimensions of 20, 70 and 90
<u>Surface are is calculated by the formula:</u>
<u>Substitute values and find the value:</u>
- SA = 2(20*70 + 20*90 + 70*90) = 19000 square units
x=16cm
y=17cm
Step-by-step explanation:
area of the sheet = 4y
area of the hole = 3x
4y-3x=20
y=x+1, so let's substitute and solve for x
4(x+1)-3x=20
4x+4-3x=20
x+4=20
x=20-4
x=16
y=17
note: my keyboard is starting to act weird and I left out the units (cm) in the explanation to simplify things

Step-by-step explanation:
The condition of the problem is not sufficient to solve the problem
You can only list equations![\left \{ {{x+y+z=72} \atop {x](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7Bx%2By%2Bz%3D72%7D%20%5Catop%20%7Bx%3Cy%3Cz%7D%7D%20%5Cright.)

So how many does he have left
25-16=9
9 floors left
the want a percentage so 9 out of 25
percent is out of 100
a hack for this specific problem is that 25 is exactly 1/4 of 100 so
9/25 times 1=the same thing so
9/25 times 4/4 (simplifies to 1)=(9 times 4)/(25 times 4)
36/100
this is out of 100 so
36%
of course there is a legit way of solving this problem but this is a hack (this works for factors of 100 like 2,4,5,10,20,25,50)
