Answer:
21 and 26 totaling 47sticks
Step-by-step explanation:
Th number of sticks form an arithmetic progression
1, 6, 11, 16...
The nth term of an arithmetic progression is expressed as;
Tn = a+(n-1)d
a is the first term = 1
d is the common difference
d = 6-1 = 11-6 = 5
n is the number of terms
The next two terms are the fifth and sixth term
T5 = 1+(5-1)5
T5 = 1+4(5)
T5 = 1+20
T5 = 21
T6 = 1+(6-1)5
T6 = 1+5(5)
T6 = 1+25
T6 = 26
Hence the number of sticks needed in the next two piles are 21 and 26 totaling 47sticks
Answer:
688 cm²
Explanation:
Area of triangular prism = Base × Height + Length × (perimeter of base)
Here given:
- Perimeter of Base: (6 + 12.4 + 12.4) = 30.8 cm
============================================
Surface Area = 6 × 12 + 20 × (30.8) = 688 cm²
Hello!
First you have to make the denominators the same
1/4 = 6/24
1/6 = 4/24
Now you add
1 6/24 + 5 4/24 = 6 10/24
This can be simplified to 6 5/12
The answer is 6 5/12
Hope this helps!
