Answer:
= 
Step-by-step explanation:
1.
The edge lengths of a triangle are inversely proportional to 2,3 and 4.
The actual proportions of the lengths are then
12(1/2:1/3:1/4)=6:4:3
The longest side
= 39* (6/(6+4+3)
= 39*6/13
=18
2. 63 breads : 35 kg flour
is the same as
54 breads : x kg flour
Cross multiply and get
x=54*35/63=30
30 kg of flour are needed to make 54 breads.
Hey! So, here's a tip. When writing exponents, an easier way is to write a^b, rather than a to the b power. Besides that, here is your answer!
So-------
9^3=729
3^2=9
6^3=216
15^2=225
Now that we have that figured out, we can add them together, wish is simple. 729 + 9 + 216 + 225= 1,179.
Therefore, your final answer will be 1,174.
If you have any questions on this, I'm happy to help you. :)
[(8 - 2 * 29)]/3
Let's solve inside the brackets first.
According to PEMDAS, multiplication gets solved before subtraction so multiply 2 * 29 in the parentheses.
[(8 - 58)]/3
Subtract 58 from 8 in the parentheses.
(-50)/3
Divide -50 by 3.
-16.667 or -16 2/3 is your answer.
