4. The sum of the first eight terms of an arithmetic sequence is 60. The sum of the 9th to 14th terms is 108. Find the 25th term.
Answers
Answer:
PLACEHOLDER SRRY BRB
Step-by-step explanation:
The formula for the sum of the first n terms of an arithmetic sequence is: Sn = n/2(2a + (n-1)d).
Using this formula, we can find the value of d:
For the first eight terms:
8/2(2a + (8-1)d) = 60
Solving for d:
d = (60 - 2a) / 14
For the next six terms:
6/2(2a + (9-1)d) = 108
Solving for a:
a = (108 - 6d) / 10
Now that we have the values of a and d, we can find the 25th term using the formula for the nth term of an arithmetic sequence: an = a + (n-1)d.
an = a + (25-1)d = a + 24d
Plugging in the values of a and d found above, we get the 25th term:
an = (108 - 6d) / 10 + 24 [(60 - 2a) / 14] = (108 - 6d) / 10 + 24 [(60 - 2(108 - 6d) / 10) / 14]
Simplifying further, we can find the 25th term

a comedy club earns $1088 from an opening night performance and $1183 from a second performance. on opening night the club sells 68 adult tickets sand 136 student tickets. on the second night the club sells 79 adult tickets and 140 student tickets what is the price of each ticket
Answers
Answer:
student tickets cost $4.50
adult tickets cost $7.00
Step-by-step explanation:
a = cost of an adult ticket
s = cost of a student ticket
(1) 68a + 136s = 1088
(2) 79a + 140s = 1183
solve (1) for a:
68a = 1088 - 136s
a = 16 - 2s substitute this into (2):
79(16-2s) + 140s = 1183
1264 - 158s + 140s = 1183 solve for s:
-18s = -81
s = -81/-18 = 4.50 plug this into either equation 1 or 2 to solve for a:
68a + 136(4.50) = 1088
68a = 1088 - 612 = 476
a = 476/68 = 7.00

Can someone solve this with the work also shown?
Answers
Answer:
a.
The growth rate (k) can be calculated using the exponential growth formula: P = P0 * e^(kt), where P0 is the initial population, t is the time in years, and e is the natural logarithm base.
From the information provided, the initial population of elves in 2000 was 23, and in 2003, the population was 34. By substituting the values into the formula and solving for k, we get:
34 = 23 * e^(k * 3)
Taking the natural logarithm of both sides:
ln(34) = ln(23 * e^(k * 3))
Using the logarithmic identity:
ln(34) = ln(23) + ln(e^(k * 3))
Solving for k:
k = (ln(34) - ln(23)) / (3) = 0.175
Therefore, the growth rate (k) for the population of elves is 0.175.
b.
To find the population of elves in 2020, we can use the exponential growth formula:
P = P0 * e^(kt)
Substituting the initial population of elves in 2000, which was 23, and the growth rate (k), which we found to be 0.175, we get:
P = 23 * e^(0.175 * 20)
Calculating the exponential function:
P = 23 * e^3.5
Therefore, there will be approximately 51 elves in 2020.
c.
To find the year when there will be 543 elves, we can use the exponential growth formula and solve for t:
543 = 23 * e^(0.175 * t)
Dividing both sides by 23 and taking the natural logarithm of both sides:
ln(543/23) = 0.175 * t
Solving for t:
t = (ln(543/23)) / 0.175
Therefore, there will be 543 elves in the year 2027.

Answer:

Answers
The quantity of butter that should be used is 120g. ii. The total quantity of flapjacks would be: 540g. b. The amount of oats would be: 75g.
What is ratio?Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.
Given that the ratio of ingredients for the recipe is 1: 2: 2: 4.
Let us suppose the syrup has a ratio of 1x, then the ratio of other ingredients are:
sugar = 2x
butter = 2x
oats = 4x
a. Tiger uses syrup, x = 60g
i. The quantity of butter that should be used is 2x = 2(60) = 120g.
ii. The total quantity of flapjacks would be:
x + 2x + 2x + 4x = 60 + 120 + 120 + 240 = 540g
b. Given that:
150g syrup = 8 flapjacks
x = 1 flapjack
Using the cross multiplication method, we have:
x = 150/8
x = 18.75g
So, for one flap jack the syrup needed is 18.75g, then the amount of oats would be: 4x = 4(18.75) = 75g.
Hence, the quantity of butter that should be used is 120g. ii. The total quantity of flapjacks would be: 540g. b. The amount of oats would be: 75g.

In the diagram below of triangle CDE, F is the midpoint of CE and G is the midpoint of DE. If m∠ECD=12+9x, m∠EFG=−2x+111, what is the measure of ∠EFG?
Answers
The measure of m∠EFG in triangle CDE is equal to 93 units.
What is the midpoint theorem?In Mathematics, the midpoint theorem states that in a triangle, the line segment which joins the midpoints of any two (2) sides of the triangle must be parallel to the third side and congruent to half of the length of the third side.
By applying the midpoint theorem to triangle CDE, the measure of m∠EFG can be calculated as follows;
m∠ECD = m∠EFG
12 + 9x = −2x + 111
9x + 2x = 111 - 12
11x = 99
x = 99/11
x = 9.
For line segment m∠EFG, we have the following:
m∠EFG = −2x + 111
m∠EFG = −2(9) + 111
m∠EFG = −18 + 111
m∠EFG = 93 units.

Δ TWZ is isosceles with ZW ≅ TW , that is

A person invested $7500 for 1 year, part at 6%, part at 9%, and the remainder at 15%. The total annual income from these investments was $867. The amount of money invested at 15% was $100 more than the amounts invested at 6% and 9% combined. Find the amount invested at each rate.
Answers
Answer: The amount invested at 6% was $1393.57, the amount invested at 9% was $306.13, and the amount invested at 15% was $1393.57 + $306.13 + $100 = $1800.70.
Step-by-step explanation:
Let's denote the amount invested at 6% as "x". Then, the amount invested at 9% would be "y", and the amount invested at 15% would be "z".
According to the problem, we have the following information:
x + y + z = $7500 (the total amount invested)
0.06x + 0.09y + 0.15z = $867 (the total annual income)
And,
z = x + y + $100 (the amount invested at 15% was $100 more than the amounts invested at 6% and 9% combined)
We can substitute the third equation into the first equation to get:
x + y + x + y + $100 = $7500
Simplifying:
2x + 2y + $100 = $7500
2x + 2y = $7400
Next, we can substitute "z = x + y + $100" into the second equation:
0.06x + 0.09y + 0.15(x + y + $100) = $867
Expanding:
0.06x + 0.09y + 0.15x + 0.15y + 0.15 * $100 = $867
0.21x + 0.24y + $15 = $867
0.21x + 0.24y = $852
Finally, we can solve for x and y using the equations "2x + 2y = $7400" and "0.21x + 0.24y = $852".
We can use elimination method to find x:
2x + 2y = $7400
0.21x + 0.24y = $852
Multiplying the first equation by 0.21:
0.42x + 0.42y = $1557.8
Subtracting the second equation from the first:
0.42x + 0.42y - 0.21x - 0.24y = $1557.8 - $852
0.21x - 0.03y = $705.8
Dividing both sides by 0.21:
x = $705.8 / 0.21 + 0.03y / 0.21
x = $3357.14 / 0.24 + y
Finally, substituting x back into the equation "2x + 2y = $7400":
2($3357.14 / 0.24 + y) + 2y = $7400
Expanding:
$6714.29 + 2.24y = $7400
Solving for y:
2.24y = $7400 - $6714.29
y = $685.71 / 2.24
y = $306.13
And finally, substituting y back into the equation "x = $3357.14 / 0.24 + y":
x = $3357.14 / 0.24 + $306.13
x = $1393.57
Therefore, the amount invested at 6% was $1393.57, the amount invested at 9% was $306.13, and the amount invested at 15% was $1393.57 + $306.13 + $100 = $1800.70.

The two rectangles above are similar. If b = 18 mm, and c = 24 mm, and d = 36 mm, what is the length of a?
Answers
Answer:
The length of a is 36 mm.
Step-by-step explanation:
Similar rectangles have the same shape, but can have different sizes. The ratio of the lengths of corresponding sides of similar rectangles is always the same.
Given that b = 18 mm, c = 24 mm, and d = 36 mm, the ratio of the lengths of corresponding sides of the two rectangles is c/d = 24/36 = 2/3.
So, the length of a is equal to b * (c/d) = 18 * (2/3) = 36 mm.
