1 gallon is equal to 4 quarts or 8 pints. How many pints are in 3 gallons?
Answer:
24 pints
Step-by-step explanation:
if 1 gallon is = to 8
then 3 gallons is 24
There are 24 pints in 3 gallons.
To determine how many pints are in 3 gallons, we can use the conversion factor provided: 1 gallon equals 8 pints.
Step 1: Calculate the number of pints in 1 gallon.
Since 1 gallon equals 8 pints, we can write this as 1 gallon = 8 pints.
Step 2: Multiply the number of pints in 1 gallon by the number of gallons.
To find the number of pints in 3 gallons, we multiply the number of pints in 1 gallon (8 pints) by 3 gallons:
3 gallons × 8 pints/gallon = 24 pints.
Therefore, there are 24 pints in 3 gallons.

Find the volume of a cone with a diameter of 12.9 cm and a height of 16.6 cm.
Answer:
112cm^3
Step-by-step explanation:
Formula for volume of a cone is:
[tex] \frac{1}{3} \times \pi \times {r}^{2} \times h[/tex]
r = radius and h = height
To find the radius you divide the diameter by 2:
12.9 ÷ 2 = 6.45
Now substitute values into the formula:
[tex] \frac{1}{3} \times \pi \times {6.45}^{2} \times 16.6[/tex]
Which equals 112cm^3

What is the value of 3^2x+1, if 3^x=a
Guys HELPPPPP
Step-by-step explanation:
We use the power rule a^(x+y) = a^x * a^y:
3^(2x+1) = 3^(2x) * 3
We can re-write 3^(2x) as (3^x)^2, and we know that 3^x = a, so:
3a^2 is the final answer. There is not exact value, it's all just about re-writing.
[tex]3a^2 [/tex] is a required answer.
Answer:

By using power rule, we can write

[tex]a^2*3=3a^2 [/tex]
Curtis has a board that is 3/4 of a yard long he cuts it to make shelves that are 1/8 of a yard long how many shelves will there be after he cuts the board ?
The number of shelves would be 6.
The length of the board and the shelves are fractions. A fraction is made up of a numerator and a denominator. An example of a fraction is 1/8. 1 is the numerator and 8 is the denominator.
In order to determine the number of shelves Curtis cut, we would divide the length of the board by the length of each shelf.
Number of shelves = length of the board / length of the shelf
3/4 ÷ 1/8
3/4 x 8 = 6

https://brainly.com/question/219464
Step-by-step explanation:
To determine the maximum number of bags John can make, we need to find the greatest common divisor (GCD) of the two quantities: 48 chocolate chip cookies and 56 peanut butter cookies.
The GCD is the largest number that divides both quantities without leaving a remainder. It represents the maximum number of bags that can be made, with each bag containing an equal number of cookies of each type.
Let's find the GCD of 48 and 56:
Step 1: List the divisors of each number:
Divisors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Divisors of 56: 1, 2, 4, 7, 8, 14, 28, 56
Step 2: Identify the common divisors in both lists:
Common divisors of 48 and 56: 1, 2, 4, 8
Step 3: Determine the greatest common divisor (GCD):
The greatest common divisor of 48 and 56 is 8.
So, John can make a maximum of 8 bags, with each bag containing an equal number of chocolate chip and peanut butter cookies.

Step-by-step explanation:
If [tex]a + ar + ar^{2} + ... = 15[/tex] and [tex]a + ar^{2} + ar^{4} + ar^{6} + ... = 9[/tex], then what is the sum of the geometric series [tex]a + ar^{3} + ar^{6} + ar^{9} + ...[/tex]?
Notice that
a + ar³ + ar⁶ + ar⁹ + ... = a + r³ (a + ar³ + ar⁶ + ...)
but the grouped sum on the right side is the same as the sum on the left side. This means that, if the sum we want to compute
a + ar³ + ar⁶ + ar⁹ + ...
converges to S, then
S = a + r³ S
Solve for S :
S - r³ S = a
(1 - r³) S = a
S = a/(1 - r³)
Similarly, knowing the value of the first sum, we have
a + ar + ar² + ar³ + ... = a + r (a + ar + ar² + ...)
but we know
a + ar + ar² + ... = 15
so
15 = a + 15r
and knowing the value of the second sum, we have
a + ar² + ar⁴ + ... = a + r² (a + ar² + ar⁴ + ...)
so
9 = a + 9r²
Solve these two equations for a and r :
15 = a + 15r ⇒ a = 15 - 15r
9 = a + 9r² ⇒ 9 = 15 - 15r + 9r² ⇒ 3r² - 5r + 2 = (3r - 2) (r - 1) = 0
⇒ r = 2/3 or r = 1
We cannot have r = 1, since that would mean
a + a + a + ... = 15
since the left side is adding infinitely many copies of some constant; such a sum can never converge to a finite number. So it must be that r = 2/3, and it follows that a = 15 - 15 (2/3) = 5.
Then the sum we want has a value of
S = 5/(1 - (2/3))³ = 135/19
Answer:
Step-by-step explanation:
a + ar¹ + ar² + ar³ + ... = 15 #1
r(a + ar¹ + ar² + ar³ + ...) = 15r
ar¹ + ar² + ar³ + ... = 15r #2
subtract #2 from #1
a = 15 - 15r
a + ar² + ar⁴ + ar⁶ + ... = 9 #3
r²(a + ar² + ar⁴ + ar⁶ + ... )= 9r²
ar² + ar⁴ + ar⁶ + ... = 9r² #4
subtract #4 from #3
a = 9 - 9r²
15 - 15r = 9 - 9r²
9r² - 15r + 6 = 0
3r² - 5r + 2 = 0
r = (5 ±√(5² - 4(3)(2))) / (2(3)
r = (5 ± 1) / 6
r = 1
or
r = 4/6 = 2/3
if r = 1 then a = 15 - 15(1) = 0 and a series of zeros added together can never equal 15 so r = 2/3 must be true.
a = 15 - 15(2/3) = 5
a + ar³ + ar⁶ + ar⁹ + ... = C #5
r³(a + ar³ + ar⁶ + ar⁹ + ...) = Cr³
ar³ + ar⁶ + ar⁹ + ... = Cr³ #6
subtract #6 from #5
a = C - Cr³
a = C(1 - r³)
C = a/(1 - r³)
C = 5/(1 - (2/3)³)
C = 5/(1 - 8/27)
C = 5/(19/27)
C = 5(27/19)
C = 135/19 = 7.1052631578947368....

where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the total cost for x months.
Club A charges a $35 joining fee, plus $19 per month. hence:
