Answer:
She is not breaking even. The discounted price is .84t, which is less than t.
Step-by-step explanation:
Retail price= 1.4
1.4×.4= .56
40% of 1.4 is .56
Subtract 40% of 1.4 from the retail price because she is marking down.
(1.4)-(.56)=.84
So the discounted price is .84t
This problem is difficult because we don't know if she sold any tea by the retail price and if she did how much did she sell.
A 2 meter television camera at ground level is filming the lift-off of a space shuttle at a point 750 meters from the launch pad. The camera’s angle of elevation to the shuttle is 32° at this specific time . Find the height of the shuttle.
To find the height of the shuttle, we can use trigonometry and the concept of similar triangles. The height of the shuttle is approximately 468.675 meters.
Let's assume that the height of the shuttle is represented by 'h' meters. From the information given, we know that the distance between the camera and the launch pad is 750 meters, and the angle of elevation from the camera to the shuttle is 32 degrees.
Using trigonometry, we can set up the following equation:
tan(32°) = h / 750
To find the value of h, we can rearrange the equation:
h = tan(32°) * 750
Using a calculator, we can find the value of tan(32°) ≈ 0.6249.
Now we can calculate the height of the shuttle:
h ≈ 0.6249 * 750
h ≈ 468.675 meters
Therefore, the height of the shuttle is approximately 468.675 meters.

cis 75∘+cis 83∘+cis 91∘+⋯+cis 147∘
is expressed in the form rcis θ, where 0≤θ<360∘. Find θ in degrees.
Hint: cis θ=cosθ+isinθ
Edit:
I simplified the expression down to
cis 75∘sin40∘ cis 40∘sin4∘ cis 4∘.
What should I do now?
The value of the angle θ in the rcis θ be 16 degrees.
Given, a number rcis θ, is expressed by
cis 75° + cis 83° + cis 91° + ⋯ + cis 147°
we have to find the value of θ in degrees
Now, we have to find the sum of the given expression
cis 75° + cis 83° + cis 91° + ⋯ + cis 147°
as, cis θ = e^iθ
e^i75° + e^i83° + e^i91° + ⋯ + e^i147°
e^i75π/180 + e^i83π/180 + e^i91π/180 + ⋯ + e^i147π/180
On using the geometric sum of the Geometric Progression, we get
Sum = e^i75π/180(1 - e^i72π/180)/(1 - ei^8π/180)
r cis θ = cos θ + i sin θ
θ = 16°
The value of the angle θ be 16 degrees.
Hence, the value of the angle be 16 degrees.

Find the missing angle and side measures of Delta*ABC , given that
m angle A = 50 deg , m angle C = 90 deg , and CB = 16
The missing angle is <B= 40 degree and missing side length is AB = 12.25 and AC = 19.068.
To find the missing angle and side measures of ΔABC, we can use the properties of a triangle.
Given:
∠A = 50°
∠C = 90°
CB = 16
We can start by finding the measure of ∠B:
∠A + ∠B + ∠C = 180° (Sum of angles in a triangle)
50° + ∠B + 90° = 180°
∠B + 140° = 180°
∠B = 180° - 140°
∠B = 40°
Now, using Sine law
CB/ sin A = AB / sin C
16 / sin 50 = AB / sin 90
16 / 0.766044 = AB
AB = 12.25
Again 12.25 = AC/ sin B
12.25 = AC / sin 40
AC = 19.068

If 2x-y=9 and 3x+4y=19, then y=
Answer:
x = 5
y = 1
Step-by-step explanation:
2x - y = 9
3x + 4y = 19
We multiply the first equation by 4
8x - 4y = 36
3x + 4y = 19
11x = 55
x = 5
Now we put 5 in for x and solve for y
2(5) - y = 9
10 - y = 9
-y = -1
y = 1
Let's Check the answer
2(5) - 1 = 9
10 - 1 = 9
9 = 9
So, x = 5 and y = 1 is the correct answer.

Plot four lines. Each line should pass through the point
on the y-axis and one of the other four points. One is done for you.
The necessary equations for the lines are y = 5/3x, y = -3/4x, and y = -4x, respectively, which cross the y axis at the point (-3, -5), (-4, 3), and (1, -4).
How do lines work?The shortest path between two places is what is referred to as a line. The equation for the line is typically written as y = mx + c, where c stands for intercept and m, for slope.
Three lines are to be plotted on the curve that passes through (-3, -5), (-4, 3), and (1, -4) in this case. At any point on the y-axis, any of the three lines should intersect.
In other words, the y=5/3x equation runs between (-3, -5) and 0 on the y-axis.
On the y axis, y = -3/4x goes between (-4, 3) and 0.
On the y axis, y = -4x goes between (1, -4) and 0.
As a result, the necessary equations for the lines are y = 5/3x, y = -3/4x, and y = -4x, respectively, which pass through the y axis and the locations (-3, -5) (-4, 3), and (1, -4)

A right triangle A right triangle has a hypotenuse of 24 cm and a height of 16 cm. What is the approximate perimeter of the triangle?
The approximate perimeter of the right triangle is 57.89 cm.
To find the perimeter of the right triangle, we need to know the lengths of the other two sides.
Let's use the Pythagorean theorem, which asserts that the hypotenuse (the longest side) of a right triangle has a square whose sum is equal to the squares of the other two sides.
In this case, we know the length of the hypotenuse is 24 cm and the height (one of the other sides) is 16 cm. Let's call the third side x.
So we have:
\(24^2 = 16^2 + x^2\)
Simplifying, we get:
\(576 = 256 + x^2\)
Subtracting 256 from both sides, we get:
\(320 = x^2\)
Taking the square root of both sides, we get:
x ≈ 17.89
So the approximate perimeter of the triangle is:
P = 24 + 16 + 17.89 ≈ 57.89 cm

By definition of real field and algebra properties we conclude that the product of three positive integers is always equal to a positive integer.
How to make a conjecture
First, we state the conjecture: The product of three positive integers equals a positive integer. Second, we prove if the conjecture is true:
Integers are part of the real field, which mean that the product of two integers is also an element of that field. By algebra we know that the product of two positive integers is equal to another positive integer. Thus, the product of three positive integers is always equal to a positive integer.
Here is an example:

A large random sample of soda cans found that the volume of soda in a can had a normal distribution with a mean volume of 12 fl oz of soda and a standard deviation of 0.11 fl oz. Based on this, what percent of soda cans would have a volume less than 11.8 fl oz?
Use the standard normal table to look up the percent. Put your answer in percent form, and round to two decimal places. Do not include the percent symbol.
3.51 percent of soda cans would have a volume less than 11.8 fl oz.
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
\(z=\frac{x-\mu}{\sigma} \\\\Where\ x\ is\ raw \ score,\mu=mean,\sigma=standard\ deviation\\\\\\Given\ that\ \mu=12,\sigma=0.11:For\ x<11.8\\\\z=\frac{11.8-12}{0.11}=-1.81\\\\\)
From the normal distribution table, P(x < 11.8 ) = P(z < -1.81) = 0.0351 = 3.51%
Therefore, 3.51 percent of soda cans would have a volume less than 11.8 fl oz.

How do you draw a number line for the problem 5 6/7- 2 2/3?
The number line can be drawn for this subtraction by the steps described below.
What is Number Line?A number line is a straight line drawn horizontally where the numbers are placed at an equal intervals.
Given operation is 5 6/7- 2 2/3.
Divide the portion between 5 and 6 into 7 parts.
Mark the 6th part, which is 5 6/7. Draw a line from 0 to 5 6/7.
Similarly, divide the portion between 2 and 3 into 3 parts.
Mark the 2nd part, which is 2 2/3. Draw a line from 0 to 2 2/3.
This is an operation of mixed fraction.
First convert this into improper fractions.
5 6/7 = (5 × 7 + 6) / 7 = 41/7
2 2/3 = (2 × 3 + 2) / 3 = 8/3
So, 5 6/7- 2 2/3 = 41/7 - 8/3
Doing the cross multiplication,
5 6/7- 2 2/3 = 41/7 - 8/3
= [(41 × 3) - (8 × 7)] / (7 × 3)
= (123 - 56) / 21
= 67/21
= 3 4/21
The resulting length is 3 4/21, which is the portion which is included in 5 6/7 but not in 2 2/3.
Hence the number line can be drawn to indicate subtraction.
