Answer:
r = 4/5
Step-by-step explanation:
Formula
Sum of an infinite geometric series = a / (1 - r)
Givens
Sum = 5*a
a = a
r = ?
Solution
5a = a/(1 - r) Divide both sides by a
5a/a = a / (a * (1 - r) The a's on the right cancel
5 = 1 / (1 - r) Multiply both sides by 1 - r
5*(1 - r) = 1*(1 - r)/(1 - r) The 1 - r s on the right cancel
5*(1 - r) = 1 Remove the brackets.
5 - 5r = 1 Subtract 5 from both sides
5-5 - 5r = 1 - 5 Combine
-5r = - 4 Divide by - 5
r = 4/5
Answer:
Nika can make 15 cups of milk.
Step-by-step explanation:
To find how many cups she can make, we divide 3 3/4 by 1/4. First, we convert 3 3/4 to an improper fraction.
3 ¾ / ¼ Equation
15/4 / ¼ Convert to improper
15/4 * 4/1 Reverse sign & second fraction
= 60/4
= 15
Also, 15 * 1/4 = 3 ¾, so its correct!
Answer:
Constants: The terms which are free from variables.
Numerical coefficient: Number multiplied with a variable.
(i) Constant = -3
Term which is not constant = 5x
Numerical coefficient = 5
(ii) 5x-3
Constant = 11
Term which is not constant
Numerical coefficient = -2
(iii) 11-2y squared
Constant = -1
Term which is not constant = 2x
Numerical coefficient = 2
Therefore, the terms which are not constants are 5x,-2y squared,2x respectively and their numerical coefficients are 5, -2, 2 respectively.
