Answer:
17.98
Step-by-step explanation:
We can use the sum of a finite geometric series formula(in the picture). We can start by plugging in what we have. As of now, we have the first term, 12 and by dividing a term by a previous term, we can tell that the common ratio, r is 1/3. Lastly, we can say that n is equal to 6, because we are looking for the sum of the first 6 terms. After substituting we get:
[tex]\frac{12 - 12*(\frac{1}{3})^6}{1-\frac{1}{3} }[/tex]
We can start by simplifying:
[tex]\frac{12-12(\frac{1}{729}) }{\frac{2}{3} }[/tex]
[tex]\frac{\frac{2916}{243} -\frac{4}{243} }{\frac{2}{3} }[/tex]
[tex]\frac{\frac{2912}{243} }{\frac{2}{3} }[/tex]
[tex]\frac{2912}{243}*\frac{3}{2}[/tex]
[tex]\frac{1456}{81}[/tex]
17.975308642
This can be rounded to 17.98
Answer:
17.98Step-by-step explanation:
Given:
a₁ = 12r = 1/3n = 6Find the sum:
Sₙ = 12(1 - (1/3)⁶)/(1 - 1/3) = 12(1 - 1/729) / (2/3) = 18(728/729) = 17.98 roundedRelated Questions

Dorian buys one 32-ounce can of purple paint witha red to blue ratio of 3 to 5. He buys a 25-ouncee can of a different shade of purple paintwith a red to blue ratio of 3 to 2. Dorian mixes the two cans together. What is the ratioof red paint to blue paint in Dorian's new mixture?
Answers
Answer:
9 : 10
Step-by-step explanation:
For 32 ounce- can
Dorian buys one 32-ounce can of purple paint with a red to blue ratio of 3 to 5.
The sum of proportion = 3 + 5 = 8
The number of ounces of red paint = 3/8 × 32-ounce = 12 ounces
The number of ounces of blue paint = 5/8 × 32-ounce = 20 ounces
For 25 ounce can
He buys a 25-ounce can of a different shade of purple paint with a red to blue ratio of 3 to 2.
The sum of proportion = 3 + 2 = 5
The number of ounces of red paint = 3/5 × 25-ounce = 15 ounces
The number of ounces of blue paint = 2/5 × 25-ounce = 10 ounces
Dorian mixes the two cans together.
The total ounces for red paint
= 12 ounces + 15 ounces = 27 ounces
The total ounces for blue paint
= 20 ounces + 10 ounces = 30 ounces
Hence, the ratio of red paint to blue paint in Dorian's new mixture is
Red : Blue
27 ounces : 30 ounces
9 : 10
