Here, Sequence : -2, -6, -18, -54
Common Ratio = a₂/a₁ = -6/-2 = 3
As the expression is in negative sign, it's sequence will be -3ˣ
Where x = number of terms in the sequence [ By this rule, you can calculate the unknown nth number]
In short, Option C is your answer!!!!
Let me know, if you have some doubt.
Answer:
BD = 4.99
Step-by-step explanation:
You can simply use the trigonometric identity tangent to solve for length BD.
Tan = opposite/adjacent
In this case we have,
Tan 31 = 3/BD
BD = 3/Tan 31
BD = 4.99
It think it would be F(x)
Answer:
Step-by-step explanation:
3/8+ 1/8 = 4/8
Answer:
According to the first image, 1 cupcake costs $1.5.
So, we can use the rule of three to complete the table.
If 1 cupcake costs $1.5, 5 cupcakes would be $1.5(5)=$7.50
And 18 cupcakes would be $1.5(18)=$27.
However, $18 how many cupcakes represent?

Therefore, 12 cupcakes costs $18.
So, the table would be:
Cupcakes Prices
5 $7.50
12 $18
18 $27
