Answer:
k = 96/7
Step-by-step explanation:
Answer: the missing values are 7, 28 and 14
Step-by-step explanation:
In a proportional relationship, there is a constant relationship between the given variables. Thus, for any change in the value of one variable, there is a corresponding change in the value of the other variable.
The table shows a proportional relationship between values of servings
12 ,4 16 ,8
and values of ounces
21 ? ? ?
Let the missing values be x, y and z
Therefore,
21/12 = x/4
1.75 = x/4
x = 4 × 1.75
x = 7
21/12 = y/16
y = 16 × 1.75 = 28
21/12 = z/8
z = 1.75 × 8 = 14
the answer is on the picture
Sn=A1(1-r^n)/(1-r)
Sum of a finite geometric series formula
We know the sum, number of terms and rate, so you plug those in.
-255=A1(1-(-4)^4))/(1-(-4)
-255=A1(1-256)/5
-255=A1(-255)/5
-1275=A1(-255)
5=A1
Hope this helped! Let me know if you have any questions.
