Answer:
a(4) = 15/4
Step-by-step explanation:
The general formula for a geometric series with common ratio r and first term a(1) is
a(n) = a(1)*r^(n - 1)
and so, if a(1) = 30 and r = 1/2, we have
a(n) = 30*(1/2)^(n - 1)
and the fourth term is then:
a(4) = 30*(1/2)^(4 - 1) = 30/8 = 15/4
Answer:
It is the Coefficient
Step-by-step explanation:
Y = kx
k = y/x
k = 2/12
k = 1/6
so when x = 12
y = kx
y = 1/6(5)
y = 5/6
answer
when x = 5 y = 5/6
Answer:
25
Step-by-step explanation:
32/100=8/x
cross multiply
32x=100(8)
32x=800
/32. /32
x=25

Answer – A, B and C
Out of the four options given, the statements which are true about quadrilaterals are as follows:
A. All squares are rhombuses. (But not all rhombuses are squares)
B. All squares are rectangles (But not every rectangle is a square)
C. All rectangles are parallelograms.
Option D is wrong because trapezoids have only a pair of parallel sides while parallelograms have two pairs of parallel sides
