Complete Question
The sum of 3rd and 4th terms of GP is 108 ,The sum of 4th and 5th term of the same GP is 324 ,find common ratio
Answer:
3
Step-by-step explanation:
The formula for Number of term of a GP = ar^n-1
The sum of 3rd and 4th terms of GP is 108
ar² + ar³ = 108... Equation 1
ar²(1+ r) = 108 ..... Equation 1
The sum of 4th and 5th term of the same GP is 324 ,
ar³ + ar⁴= 324... Equation 2
ar³ (1 + r) = 324..... Equation 2
find common ratio
ar²(1+ r) = 108 ..... Equation 1
ar³ (1 + r) = 324..... Equation 2
Solving for r
ar²(1+ r)/ar³ (1 + r) = 108/324
1/r = 1/3
r = 3
Hence, Common ratio = 3

What is the area of the triangle below (in square units)?
2 mm
14 mm
Answer:
A = 14 mm²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 14 and h = 2 , then
A = [tex]\frac{1}{2}[/tex] × 14 × 2 = 7 × 2 = 14 mm²

Answer:
m<Y = 68°
Step-by-step explanation:
A tangent drawn to a circle makes a 90° angle with the radius that intersects it at the point of tangency. That means that m<X = 90°.
The sum of the measures of the angles of a triangle is 180°.
m<X + m<Y + m<Z = 180
90 + m<Y + 22 = 180
m<Y + 112 = 180
m<Y = 180 - 112
m<Y = 68

Complete the equation to show how to find the sum of 7/10 and 20/100. Write your answers in the boxes. HALP MEH PLS
Answer:
9/10
Step-by-step explanation:
To solve this you need a common denominator, here we'll make it 10, leaving 7/10 and simplifying 20/100 by dividing both the 20 and 100 by 10 to get our common denominator of 10. Now we have 7/10 + 2/10 which is 9/10.
