Answer:
number 2
Step-by-step explanation:
3*7*6=126
4*3*10=120
126-120=6
A+b=10
a^2+b^2=52
well.. 10=5,5 / 1,9 / 2,8 / 3,7 / 4,6
so 4^2+6^2=16+36=52 works
follow?!
Let t = number of hours
The first candle starts at 8 inches.
It burns at 7/10 inch per hour, so in t hours it burns (7/10)t inches.
After t hours, its length is 8 - (7/10)t
The second candle starts at 6 inches.
It burns at 1/5 inch per hour, so in t hours it burns (1/5)t inches.
After t hours, its length is 6 - (1/5)t
You want the lengths to be equal, so the equation is
8 - (7/10)t = 6 - (1/5)t
Answer:
The perimeter of △EFG is ![62\ units](https://tex.z-dn.net/?f=62%5C%20units)
Step-by-step explanation:
we know that
In the figure the smaller triangle and triangle EFG are similar by AA Similarity Theorem
so
Remember that
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
<em>Find the length side EG</em>
![\frac{9}{EF}=\frac{14}{EG}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7BEF%7D%3D%5Cfrac%7B14%7D%7BEG%7D)
substitute the given values
![\frac{9}{9+9}=\frac{14}{EG}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B9%2B9%7D%3D%5Cfrac%7B14%7D%7BEG%7D)
![\frac{9}{18}=\frac{14}{EG}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B18%7D%3D%5Cfrac%7B14%7D%7BEG%7D)
![\frac{1}{2}=\frac{14}{EG}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B14%7D%7BEG%7D)
![EG=14(2)=28\ units](https://tex.z-dn.net/?f=EG%3D14%282%29%3D28%5C%20units)
<em>Find the perimeter of △EFG</em>
![P=EF+EG+FG](https://tex.z-dn.net/?f=P%3DEF%2BEG%2BFG)
substitute
![P=2(9)+28+2(8)](https://tex.z-dn.net/?f=P%3D2%289%29%2B28%2B2%288%29)
![P=62\ units](https://tex.z-dn.net/?f=P%3D62%5C%20units)
