Answer:
4
Step-by-step explanation:
The common ratio r of a geometric sequence is obtained by dividing a term by its preceding term as follows:
1) 4/1=4
2) 16/4=4
for this sequence the common ratio
r=4
Answer:
D is the correct one
Step-by-step explanation:
The whole angle equals 72 and the partial angle equals 45
You put
72-45= 27
So 3x=27
Then you solve this equation
3x = 27
x = 27/3
x = 9
Step-by-step explanation:
Answer:
x = -1, y = 2 and z = -4.
Step-by-step explanation:
-2x + 5y + 4z = -4 ......(A)
-5x - y + z = -1 .............(B)
2y + 2z = -4..................(C) Multiply (A) by 5 and (B) by -2:
-10x + 25y + 20z = -20 ....(D)
10x + 2y - 2z = 2 ..............(E) Adding D + E:
27y + 18z = -18 Dividing by 9:
3y + 2z = -2 ............(F) Subtract: (C) - (F):
-y = -2
y = 2.
Substitute for y is (C):
4 + 2z = -4
2z = -8
z = -4.
Substitute for y and z in (A):
-2x + 5(2) + 4(-4) = -4
-2x = -10 + 16 - 4 = 2
x = -1.
You must add all sides together to get the perimeter.
The perimeter is 24
Answer:
Ok so lets break it down.
Step-by-step explanation:
5-2 = 3 now we have 1/4 and 1/10 10 divided by 4 = 2.5
So we can convert it then we have 2.5 out of ten.
then we add them up equals 3.5 out of ten.
Now we have 3.3.5 So now all we do is have to add 2.
