Answer:
=》Area = 180 sq.yd
Step-by-step explanation:
perimeter = 2l + 2b
where, we have l = 15
- so (2×15) + 2b = 54
- 30 + 2b = 54
- 2b = 24
- b = 12
now, Area = l × b = 12 × 15 = 180 sq.yd
Answer:
your answer should be B
Step-by-step explanation:
Answer:
You've completed 11/12 of your project
Only 1/12 left to go!
Step-by-step explanation:
2/3 + 1/4 = 11/12
= 1455
generate a few terms of the sequence using
= 3n + 2
= ( 3 × 1) + 2 = 5
= (3 × 2) + 2 = 8
= (3 × 3 ) + 2 = 11
= (3 × 4 ) + 2 = 14
= ( 3 × 5 ) + 2 = 17
the terms are 5, 8, 11, 14, 17
these are the terms of an arithmetic sequence
sum to n terms is calculated using
=
[ 2a + (n-1)d]
where a is the first term and d the common difference
d = 8 - 5 = 11 - 8 = 14 - 11 = 3 and
= 5
=
[( 2 × 5) + (29 × 3) ]
= 15( 10 + 87) = 15 × 97 = 1455
Since the .16 is in the hundredths place, the fraction is 2 16/100, or 216/100
But if you need to simplify it it's 2 4/25, or 54/25
