Answer:
3¾
Step-by-step explanation:
Geometric sequence also known as geometric progression, can be said to be a sequence with a constant ratio between the terms.
Formula for geometric sequence:
Given:
First term, a1 = 30
ratio, r = ½
Required:
Find the fourth term
Where, the first term, a¹ = 30
Second term: a² = 30 * ½ = 15
Third term: a³ = 15 * ½ = 7.5
Fourth term: a⁴ = 7.5 * ½ = 3.75 = 3¾
Therfore the fourth term of the geometric sequence is 3¾
Answer: yo no Abbas
Step-by-step explanation:
Step-by-step explanation:
The rectangle area is equal to LENGTH * WIDTH
then
t^2-16t+48 = L*W
L = [t^2-16t+48] / W
and
t^2-16t+48 = L*W
W = [t^2-16t+48] / L

Answer:
80 minutes or 1 hour 20 min
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
s -----> the speed in miles per hour
d ----> the distance in miles
t ----> he time in hours
so
solve for t
we have
substitute and solve for t
Convert to minutes
First, we know that the equation for permeter of a circle is C=2*pi*4 or C=2*3.14*r if you are using 3.14 for pi. Since this is a semicircle, we simply divide this equation by 2 and plug in our radius (radius id 6 because 12/2 =6)
So we are using C=3.14*r
C=3.14*6
So the perimeter equals 18.84 so A
Hope this helps!
