Answer:
a1 = 0.5; common ratio = 5
Step-by-step explanation:
Let the common ratio = r
a2 = 2.5
a3 = 2.5r
a4 = 2.5r * r = 2.5r^2
We are told a4 = 62.5, so
2.5r^2 = 62.5
Divide both sides by 2.5
r^2 = 25
r = 5
a2 = a1 * r
a1 = a2/r = 2.5/5 = 0.5
Answer: a1 = 0.5; common ratio = 5
1+2=3.
30/3=10
10x1=10
10x2=20
So the answer would be £10:£20
And to check if it’s right £10 + £20= £30
Remove parentheses.
-3/8 -1/6
Find the Least Common Denominator (LCD) of 3/8, 1/6. In other words, find the Least Common Multiple (LCM) of 8,6.
LCD=24
Make the denominators the same as the LCD.
- 3x3/8x3 - 1x4/6x4
Simplify. Denominators are now the same
-9/24 - 4/24
Join the denominators
-9-4/24
Simplify
-13/24
Answer:
105°
Step-by-step explanation:
m(15) = 75°
Also it's given that m||n . So taking y as transversal ,
m(15) = m(13) = 75°
Also it's given that x||y . So taking m as transversal ,
m(13) = m(5) = 75°
Now m(5) & m(1) are linear pair. So ,
m(5) + m(1) = 180°
=> 75° + m(1) = 180°
=> m(1) = 180° - 75°
= 105°
6.9 as a fraction or mixed number
6.9 = 6 9/10
This is also the same as 69/10
