Answer:
KI=11.25 and HI=6.75
Step-by-step explanation:
Consider the below figure attached with this question.
According to Pythagoras Theorem:

Use Pythagoras in triangle HKL




Taking square root on both sides.

Let length of HI be x.
LI = 12+x
Use Pythagoras theorem in ΔKLI,




Use Pythagoras theorem in ΔHKI,


From (1) and (2) we get



Hence, the measure of HI is 6.75 units.
Substitute x=6.75 in equation (2).


Taking square root on both sides.


Hence, the measure of KI is 11.25 units.
Roman will have to pay $89.67 for his school supplies.
Since you needed help, I’ll show you my work so you know for next time:
85.40 (.05) = 4.27
85.40 + 4.27
= 89.67
I hope this helps :)
5-(n-4)=3(n+2)
5-n+4=3n+6
9-n=3n+6
3=4n
n=3/4
Cubed root (x^2) I can’t add the radical here but it would be the 3radical(x^2)
Hey there! I'm happy to help!
When you divide fractions, you are technically multiplying by the reciprocal, which is the numerator and denominator flipped. This means that 22/33 divided by 6/9 is equal to 22/33 multiplied by 9/6.
If we multiply these together, we get an answer of 1.
I hope that this helps! Have a wonderful day!
