-4*3 1/4 would be and expression you can use
Answer:
Step-by-step explanation: multiply 4 by 12 then 4 by 3 then 4 by 9.
Answer:
22.0625
Step-by-step explanation:
Lateral surface area formula: (a+b+c)h=L
(4+5+7)h=L
(16)h=353
16h=353
h=22.0625
Hope this helps!
Answer:
The width is 8 units
Step-by-step explanation:
This is a variation problem we are to work with.
Length is inversely proportional to width, let length be l and width be w
modeling the statement mathematically, we have lw = k where k is the proportionality constant
Now let’s get k from l = 12 and w = 6
k = 12 * 6 = 72
Now for the second rectangle also;
lw = k given l = 9
9w = 72
w = 72/9
w = 8
Answer:
C
Step-by-step explanation:
The n th term formula of a geometric sequence is
= a 
where a is the first term and r the common ratio
Using the second and fourth term, then
ar = 6 → (1)
ar³ = 54 → (2)
Divide (2) by (1)
=
= 9
r² = 9 ⇒ r =
= 3 → C
