Answer:
x = 50°
Step-by-step explanation:
Angles in a quadrilateral add to 360°
First work out the interior missing angle
360° - ( 40° + 80° + 110° ) = 130°
Angles on a straight line add to 180° so
180° - 130° = 50°
Answer:
c) 0.0156
Step-by-step explanation:
The general term a[n] of a geometric sequence is given in terms of the first term a[1] and common ratio r as ...
a[n] = a[1]r^(n-1)
The given sequence has an initial term of a[1]=8 and a common ratio of 4/8=1/2. Then the general term is ...
a[n] = 8(1/2)^(n-1)
The 10th term is then ...
a[10] = 8(1/2)^(10-1) = 8(1/2)^9 = 8/512
a[10] = 0.015625 ≈ 0.0156
Answer:
80
Step-by-step explanation:
500 to 900? = 80.
Answer:
R=-13
Step-by-step explanation:
S=-1-r/5-2
4=-1-r/3
Cross multiply
4*3=-1-r
12=-1-r
Collect like terms
12+1=-r
-r=13
Divide both sides by -
r=-13
it is greater than because when you multiply 8 by 3 you get 24
and you get the 3 because 3 feet make 1 yard.
