The sum of the first six terms of the geometric series is -364.
A geometric series is a sequence of terms in a fixed common ratio.
Apparently, the expression "geometric progression" comes from the "geometric mean" (Euclidean term) of segments of lengths a and b: it is the length of the side c of a square whose area is equal to the area of the rectangle. a and b. May
The series given is

Write the equation of the line, in
standard form Ax+By=C, that has a
slope of -4 and passes through the point
(1, -3).
(Do NOT put any spaces between terms
when you type in your answer below.)
Answer:
4x + y = 1
Step-by-step explanation:
Start with the familiar format of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).
With a slope of -4, we can write:
y = -4x + b
We need to find a value for b that forces the line through point (1,-3). This is done by entering this point in the equation and solving for b:
y = -4x + b
-3 = -4*(1) + b
b = 1
The equation is y = -4x + 1, This can be rewritten as:
4x + y = 1

a cake shop sells cakes and cupcakes. a cake uses 5 cups of cake batter. a batch of cupcakes uses 4 cups of batter. the pastry chef has 40 cups of cake batter and wants to make at least 4 cakes. the profit on a cake is $35 and the profit for a batch of cupcakes is $30. How many cakes and batches of cupcakes should the pastry chef make in order to maximize profits? what is the maximum revenue?
Chef should prepare 4 cakes and 5 batches of pastry in order to achieve maximum profits and his maximum profit or revenue by solving through inequality is $260.
Given Chef uses 5 cups of cake batter for 1 cake and 4 cups of batter for 1 batch of cupcakes. Chef wants to make at least 4 cakes. Profit on 1 cake is $35 and $30 for 1 batch of cupcake.
let the number of cakes be x and the number of batches of cupcakes be y such that
5x+4y<=40--------1
x>=4---------------2
Maximize Profit=35x+30y
Inequalities contains different signs so we have to change one inequality.
5x+4y<=40
-x<=-4
Now assume them equalities
5x+4y=40-------3
-x=-4
multiply second equations by 5
-5x=-20-----------4
now add 3 and 4
5x+4y-5x=40-20
4y=20
y=5
now put the value of y in 5x+4y=40
5x+4*5=40
5x+20=40
5x=20
x=4.
Maximum Profit=35x+30y
=35*4+30*5
=$260
Hence chef should make 4 cakes and 5 batches of pastry and maximum profit of $260.

Find the surface area. Round your answer to the nearest hundredths, if necessary. Leave your answer in terms of for answers that contain .
Answer:
Area of triangle = (base x height)/2
There are all together 4 triangles and 1 square.
Therefore, surface area = area of square + 4 x area of triangle
height = 5.8 in, base = 6 in. area of square = 6x6 = 36 in^2.
area of 1 triangle = (5.8x6)/2
area of 4 triangles = 2x5.8x6 = 69.6 in^2
surface area = 69.6 + 36 = 105.6 in^2

The proportion of people who preferred foreign cars than domestic cars is 0.24 and the confidence interval for the population proportion of new cars over domestic cars of 98% confidence interval is (641.955,642.045).
Given sample size of 2676 and number of people preferred foreign cars than domestic cars is 642.
We have to calculate the proportion of people who preferred foreign cars than domestic cars and the confidence interval which shows the confidence interval of 98%.
Number of people prefer foreign cars than domestic cars=642
Sample size=2676
Proportion=642/2676
=0.2399
=0.24 (After rounding off)
Now we will find confidence interval.
X=642
n=2676
z value for the confidence interval 98% is 2.33
Confidence interval =X± z*s/[tex]\sqrt{n}[/tex]
Upper =642+2.33*1/[tex]\sqrt{2676}[/tex] (we have taken s=1)
=642+0.045

Lower=642-2.33*1/[tex]\sqrt{2676}[/tex]
642-0.045 (putting values in formula given above)

The new amount of neon gas when the temperature drops is 2.30L.
Charles's law
Charles's law states, "The volume occupied by a particular amount of gas is directly proportional to its absolute temperature.
Initial temperature of gas T₁ = 50 ° C = 323.15K
Initial volume of gas V₁ = 2.5L
Final temperature T₂ = 25 ° C = 298.15K
Final capacity V₂ =? Neon gas, substitute the given value into the above equation:
V₁ / T₁ = V₂ / T₂
V₂ = V₁T₂ / T₁
V₂ = (2.5L × 298.15K) ) / 323.15K
V₂ = 2.30 l
Therefore, the new volume when the temperature of the neon gas drops is 2.30l.

Answer:
A. 2.3
Step-by-step explanation:
Solve to find x and y in the diagram.
The figure shows two parallel lines and a transversal. The intersection of the first line and the transversal forms four angles, the bottom right angle measures 5 times x plus 4 times y degrees. The intersection of the second line and the transversal forms four angles, the top right angle is labeled as a right angle, the bottom right angle measures 12 times y degrees.
Considering the given information in the question, the value of x is [tex]12^{o}[/tex], and that of y is [tex]7.5^{o}[/tex].
A transversal is a line that cuts through two given parallel lines. Thus it intersects each parallel line at a point, forming four angles each.
From the given information in the question, it can be inferred that:
the given bottom right angle of the first intersection and the bottom right angle with the second intersection are congruent (corresponding angle property).
So that,
[tex](5x+4y)^{o}[/tex] = [tex](12y)^{o}[/tex]
[tex]5x^{o}[/tex] = [tex]12y^{o}[/tex] - [tex]4y^{o}[/tex]
[tex]5x^{o}[/tex] = [tex]8y^{o}[/tex]............ 1
Also given that the top right angle at the second intersection is a right angle, then;
[tex]12y^{o}[/tex] + [tex]90^{o}[/tex] = [tex]180^{o}[/tex] (sum of angles on a straight line)
This implies that;
[tex]12y^{o}[/tex] = [tex]180^{o}[/tex] - [tex]90^{o}[/tex]
[tex]12y^{o}[/tex] = [tex]90^{o}[/tex]
So that,
y = [tex]\frac{90}{12}[/tex]
y = [tex]7.5^{o}[/tex]
Thus substituting the value of y in equation 1, we have;
[tex]5x^{o}[/tex] = [tex]8y^{o}[/tex]........ 1
= 8(7.5)
5x = 60
x = [tex]\frac{60}{5}[/tex]
x = [tex]12^{o}[/tex]
Therefore, x = [tex]12^{o}[/tex] and y = [tex]7.5^{o}[/tex]

Which equation represents the measure of the unknown angles?
The equation which represents the measure of the unknown angles is x + x + 10 =130. Hence, option C is correct.
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
As per the data given in the question,
As per the rules, the sum of the three sides of a triangle is 180°.
The angles are x, x+10, and 50.
Now,
x + x + 10 + 50 = 180
x + x + 10 = 180 - 50
x + x + 10 = 130°.
Therefore, the equation option above is the correct answer.

A bag contains marbles of 2 colors - green and blue. The theoretical probability of choosing a green marble is 0.55. The number of green marbles is 22. Find the number of blue marbles in the bag.
The number of blue marbles in the bag is 18.
What is the number of blue marbles?Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
Probability of choosing a green marble = total number of green marbles / total number of marbles

Combinations refers to a technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Total numbers available to be selected are 5 from 0 to 4.
In this 0 is also included because it is also a number.
