Im sorry , the second point , do u mean its a -4
0.18y + 0.03y + 240 = 1290
0.21y + 240 = 1290
0.21y = 1050
y= 5,000
9x+y=2
-4x-y=-17
Elimination
5x=-15
Divide both sides by 5
x=-3
Find y now
plug x into either equations
-4(-3)-y=-17
multiply -4 to -3
12-y=-17
subtract both sides by 12
-y=-29
divide both sides by negative 1
y=29
Solution = (-3,29)
Answer:
252°
Step-by-step explanation:
Given
Shape: Decagon
Required
Determine the value of n
A Decagon has 10 sides and a complete rotation takes 360°
First, we need to calculate the angle of each rotation as follows.
Each Rotation = ⅒ * 360°
Each Rotation = 360°
Next, we determine the possible values of n.
The statement is represented as "possible values of n" because n can assume infinite number of values.
However, n must be a multiple of 36
From the list of given options.
10, 150 and 225 are not multiples of 36
Only 252 happens to be a multiple of 36 from the list of given options.
Hence, option D answers the question [base on the given options]
Because we are given the area, work backwards by taking the square root for each sides of formula.
A (area) = 2 * (L/Length) / or (L/Length)^2
A = L2
99 ft^2 = L^2
√99 ft^2 = √L^2
9.9498743710662 ft = L
So, Length (L) = 9.9498743710662 ft.
(this length value applies for 4 (4x) since it's a 4-equal side polygon shape)
