Answer:
f = 2 1/4
Step-by-step explanation:
f-3/4=1 1/2
Add 3/4 to each side
f-3/4+3/4=1 1/2+3/4
f = 1 1/2 +3/4
Get a common denominator
f= 1 2/4 + 3/4
= 1 5/4
= 1 + 4/4 + 1/4
= 2 1/4
Answer:
true
Step-by-step explanation:
A composite shape or a composite figure is a two-dimensional figure made up of basic two-dimensional shapes such as triangles, rectangles, circles, semi-circles, etc.
The rule is to add 5/6. so the unknown term should be 4 1/3 because 3 1/2 + 5/6 = 4 1/3
Answer: c) 277,200
Step-by-step explanation:
The number of permutations can be formed of n things , where a things are like b things are like and so on :
![\dfrac{n!}{a!\ b!....}](https://tex.z-dn.net/?f=%5Cdfrac%7Bn%21%7D%7Ba%21%5C%20b%21....%7D)
The given word : ENGINEERING
Total letters = 11
Number of E's = 3
Number of N's = 3
Number of G's =2
Number of I's =2
The number of permutations can be formed from all the letters in the word "ENGINEERING" will be :
![\dfrac{11!}{3!3!2!2!}\\\\=\dfrac{11\times10\times9\times8\times7\times6}{6\times6\times2\times2}\\\\=277200](https://tex.z-dn.net/?f=%5Cdfrac%7B11%21%7D%7B3%213%212%212%21%7D%5C%5C%5C%5C%3D%5Cdfrac%7B11%5Ctimes10%5Ctimes9%5Ctimes8%5Ctimes7%5Ctimes6%7D%7B6%5Ctimes6%5Ctimes2%5Ctimes2%7D%5C%5C%5C%5C%3D277200)
Hence, the number of permutations can be formed from all the letters in the word "ENGINEERING" = 277,200
∴ Correct answer is c) 277,200
