We have 8/27 + 25/9 = 24/81 + 225/81 = 249/81 = 3.07;
Answer:
Rectangle has two(2) lines of reflections
A square has four(4) lines of reflections
Step-by-step explanation:
Lines of reflection also known as lines of symmetry ,
In a rectangle there are two( 2) lines of symmetry and they are found along the midpoints of the opposite side of the rectangle, while for A square there are four (4) lines of reflections which can be seen along the midpoint of the opposite sides of the square and also along the midpoint of the opposite vertices of the square.
Answer:
1/3
Step-by-step explanation:
Simplify the following:
1 - 2/3
Put 1 - 2/3 over the common denominator 3. 1 - 2/3 = 3/3 - 2/3:
3/3 - 2/3
3/3 - 2/3 = (3 - 2)/3:
(3 - 2)/3
3 - 2 = 1:
Answer: 1/3
Answer:
1370
Step-by-step explanation:
<h3>Given</h3>
- AP with d= 7 and a₂₂ = 149
<h3>To find</h3>
<h3>Solution</h3>
<u>First, let's get the value of the first term:</u>
- aₙ = a + (n-1)d
- a₂₂ = a + 21d
- 149 = a + 21*7
- a = 149 - 147
- a= 2
<u>Next, let's find the sum of the first 20 terms</u>
- Sₙ = 1/2n(2a+ (n-1)d)
- S₂₀ = 1/2*20(2*2 + 19*7) = 10(4 + 133) = 10*137 = 1370
<u>Answer is</u> 1370
