Answer:
Number of instructors are 225.
Step-by-step explanation:
Given:
Total number of employees at bright mind learning = 300
Number of instructors = 75%
We have to convert this percentage and find the number.
So,
can be written as ![\frac{75}{100}=0.75](https://tex.z-dn.net/?f=%5Cfrac%7B75%7D%7B100%7D%3D0.75)
Now 75% of 300 employees are the instructors at Bright mind learning.
Can be written as ![0.75*300=225](https://tex.z-dn.net/?f=0.75%2A300%3D225)
Number of instructors at Bright mind learning =225
Answer:
15.8745

No because brackets represent multiplication, so (84)5(73)9 is actually 84.5.73.9
The length of side of triangle is 5 units and length of side of pentagon is 1.5 units.
<u>SOLUTION:</u>
Given, An equilateral triangle has sides of length
units.
Then, perimeter of the triangle will be ![3 \times(3 k-2)=9 k-6](https://tex.z-dn.net/?f=3%20%5Ctimes%283%20k-2%29%3D9%20k-6)
A regular pentagon (5 sides) has sides of
units.
Then, perimeter of the pentagon will be ![5 \times(2 k+0.5)=10 k+2.5](https://tex.z-dn.net/?f=5%20%5Ctimes%282%20k%2B0.5%29%3D10%20k%2B2.5)
We have to find the dimensions of each shape
. Now, the perimeter of the triangle is twice the perimeter of the pentagon,
So, ![\text {perimeter of triangle} = 2\times \text{perimeter of pentagon}](https://tex.z-dn.net/?f=%5Ctext%20%7Bperimeter%20of%20triangle%7D%20%3D%202%5Ctimes%20%5Ctext%7Bperimeter%20of%20pentagon%7D)
![\begin{array}{l}{\rightarrow 9 k-6=2(10 k+2.5)} \\\\ {\rightarrow 9 k-6=20 k+5} \\\\ {\rightarrow 20 k-9 k=-6-5} \\\\ {\rightarrow 11 k=-11} \\\\ {\rightarrow k=-1}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B%5Crightarrow%209%20k-6%3D2%2810%20k%2B2.5%29%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%209%20k-6%3D20%20k%2B5%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%2020%20k-9%20k%3D-6-5%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%2011%20k%3D-11%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%20k%3D-1%7D%5Cend%7Barray%7D)
Then, length of side of triangle
Length of side of pentagon
We have to neglect, negative sign as lengths can’t be negative. Even if we change the sign above all conditions are satisfied.
