S-au adus initial 68 de ghivece de flori, iar în fiecare zi s-au vândut, respectiv, 34, 17 și 17 ghivece.
Initial, la florărie s-au adus x ghivece de flori. În prima zi s-au vândut 1/2 * x ghivece. A doua zi, din numărul rămas s-au vândut 1/4 * (x - 1/2 * x) ghivece, adică 1/4 * 1/2 * x.
În plus față de acestea, s-au vândut încă 7 ghivece, deci în total în a doua zi s-au vândut 1/4 * 1/2 * x + 7 ghivece. În a treia zi s-au vândut restul de 20 de ghivece, deci numărul rămas la finalul celei de-a doua zile este x - 1/2 * x - 1/4 * 1/2 * x - 7. Trebuie să fie egal cu 20, deci avem ecuația x - 1/2 * x - 1/4 * 1/2 * x - 7 = 20.
Rezolvând această ecuație, obținem x = 128. Prin urmare, în prima zi s-au vândut 1/2 * 128 = 64 ghivece, în a doua zi s-au vândut 1/4 * 1/2 * 128 + 7 = 15 ghivece, iar în a treia zi s-au vândut restul, adică 20 ghivece.

Define about 2 variable linear equation?A set of two or more linear equations with two or more variables each constitutes a system of linear equations, all of which are taken into account simultaneously. Finding a numerical value for every variable in the system that will simultaneously satisfy all of the system's equations is necessary to identify the one and only solution to a system of linear equations.
Given data:
Cost for each students = $7Cost for each adult = $10Total people = 110Total earnings = $950Let 'x' be the number of students.
Let 'y' be the number of adults.
Thus, linear equations formed:
x + y = 110
x = 110 - y .... eq 1
7x + 10y = 950 ..eq 2
Put x in eq 2
7(110 - y) + 10y = 950
770 - 7y + 10y = 950
3y = 180
y = 60
x = 110 - 60 = 50
Thus, the number of students attended at the school place is found to be 50.

Answer: a = 7, b = 14, c = 7, d = 7√3
Step-by-step explanation:
Using SOHCAHTOA, we can find a:
sin(45) = a / (7√2)
a = (7√2) sin(45) = 7We can use either SOHCAHTOA or Phthagoras' Theorem to find c. I will use SOHCAHTOA as I prefer this:
cos(45) = c / (7√2)
c = (7√2) cos(45) = 7SOHCAHTOA for b:
sin(30) = a / b = 7 / b
b = 7 / sin(30) = 14SOHCAHTOA for d:

The estimate for the amount of cubic meters of paint needed to apply a coat of paint 0.18 cm thick to a hemispherical dome with diameter 60 meters is option (b). 3.241 cubic meters
To estimate the amount of cubic meters of paint needed to apply a coat of paint 0.18 cm thick to a hemispherical dome with diameter 60 meters using differentials, we can use the formula for the volume of a sphere:
V = (4/3)πr^3
Since we have a hemisphere, we need to divide the volume by 2:
V = (2/3)πr^3
To find the change in volume due to the layer of paint, we can use differentials:
dV = (2πr^2)dr
We want to find the change in volume for a layer of paint 0.18 cm thick, which is equivalent to 0.0018 meters. We can use this to find the radius of the dome with the added layer of paint:
r' = r + 0.0018
r' = 30.0009 meters
Plugging this value into the differential equation, we get:
dV = (2π(30.0009)^2)(0.0018)
dV = 3.241 cubic meters

To find the polar coordinates (r, θ) of a point given in Cartesian coordinates (x, y), we use the following formulas:
r = √\((x^2 + y^2)\)
θ = arctan(y / x)
Let's apply these formulas to the given point (4, 4√3):
(i) For r > 0 and 0 ≤ θ < 2π:
Using the formulas, we have:
r = √\((4^2 + (4\sqrt3)^2)\) = √(16 + 48) = √64 = 8
θ = arctan((4√3) / 4) = arctan(√3) = π/3
Therefore, the polar coordinates (r, θ) of the point (4, 4√3) are (8, π/3).
(ii) For r < 0 and 0 ≤ θ < 2π:
Since r cannot be negative in polar coordinates, there are no polar coordinates for this point when r is negative.
Hence, the polar coordinates (r, θ) of the point (4, 4√3) are (8, π/3) for r > 0 and 0 ≤ θ < 2π.

The equation of the circle passing through the point (-6, 3) having center at (5, - 4) is (x - 5)² + (y + 4)² = 170
The general equation of a circle with (h, k) representing the circle's center, and {r} represents the length of its radius is
(x – h)² + (y – k)² = r²
We can write the equation of the circle as -
(x – h)² + (y – k)² = r²
(x - 5)² + (y + 4)² = (11)² + (-7)²
(x - 5)² + (y + 4)² = 121 + 49

What is the half angle formula?
The half angle formula is a mathematical formula used to find the sine, cosine, or tangent of half of an angle in a right triangle.
In a right triangle, the half angle formula allows you to find the value of one of the trigonometric functions for half of an angle based on the value of that same function for the full angle.
This can be useful when trying to simplify or solve more complex trigonometry problems.
For example, if you know the sine of an angle in a right triangle, you can use the half angle formula to find the sine of half of that angle. This can help you to find other values in the triangle, such as the cosine or tangent.
To use the half angle formula, you first need to determine which trigonometric function you want to find for half of the angle.
Then, you use the formula for that function to find the value of the trigonometric function for half of the angle based on the value of that same function for the full angle.

Find the coordinates of the image of M(−1, 5) after the translation (x, y)→(x+3, y−2).
Answer:
To find a translation image of a shape, you can use the following rule or formula. Suppose you want to translate or slide point P a units horizontally and b units vertically. Then, change the x-values and y-values of the coordinates of P. The points of the triangle of are A(-3, 1), B(-4, 3), and C(-2, 4).
Translation involves moving a point on a coordinate geometry from one position to another position.
Given that:
\(M = (-1,5)\) --- point
\((x,y) \to (x + 3, y - 2)\) --- translation rule
Substitute -1 for x and 5 for y in \((x,y) \to (x + 3, y - 2)\)
So, we have:
\((-1,5) \to (-1 + 3, 5 - 2)\)
\((-1,5) \to (2, 3)\)
This means that:
\(M' = (2, 3)\)
Hence, the image of M after translation is \((2, 3)\)

sixty-four percent of those that use drive through services believe that the employees are at least somewhat rude. if you asked 87 people who use drive through services if they believe that the employees are at least somewhat rude, what is the probability that at most 50 say yes?
The probability of the event that at most 50 out of 87 people say yes is approximately 0.0188 or 1.88%.
At first, we have to find the probability that at most 50 out of 87 people say yes, we need to use the binomial probability formula.
The binomial probability formula is given by:
P(X ≤ k) = Σ [ \(C(n, k) * p^k * (1 - p)^{(n - k)\) ]
where:
P(X ≤ k) is the probability that the random variable X is less than or equal to k.
n is the total number of trials or people surveyed (87 in this case).
k represents the number of successes (in this case, the number of people who believe the employees are at least somewhat rude).
p is the probability of success on a single trial (64% or 0.64 in decimal form).
Now, we find the probability that at most 50 out of 87 people say yes:
P(X ≤ 50) = Σ [ \(C(87, k) * 0.64^k * (1 - 0.64)^{(87 - k)\) ]
We need to sum the individual probabilities for k = 0, 1, 2, ..., 50.
we get,
P(X ≤ 50) ≈ 0.0188
So, the probability that at most 50 out of 87 people say yes is approximately 0.0188 or 1.88%.

Answer:
The sales tax rate is 8%.
C. The sale price is 20% less than the regular price
Step-by-step explanation:
Here are the options to this question :
A) The sales tax rate is 6%
B) The sales tax rate is 8%.
C. The sale price is 20% less than the regular price
Sales tax rate = (tax paid / discounted selling price) x 100
tax paid = amount customer paid - discounted selling price
$73.44 - $68 = $5.44
($5.44 / $68) x 100 = 8%
The sales tax is 8%
Sales price = (discount / initial price) x 100
discount = $85 - $68 = $17
($17 / 85) x 100 = 20%
Answer:
B.) The Sales Tax Rate is 8%
C.) 85-68/85 = discount rate
E.) The Sale Price is 20% less than the regular price.

Question 1-3
20 points
Answer:
1. x = 15
y = 15√3
2. x ≈ 20,0
3. x ≈ 49,9°
Step-by-step explanation:
1. First, use trigonometry to find x:
\( \sin(30°) = \frac{x}{30} \)
\(x = 30 \times \sin(30°) = 15\)
Now use the Pythagorean theorem to find y:
\( {?}^{2} = {30}^{2} - {15}^{2} = 900 - 225 = 675\)
\(y > 0\)
\(y = \sqrt{675} = 15 \sqrt{3} \)
2. Use trigonometry to find x:
\( \cos(32°) = \frac{x}{24} \)
\(x = 24 \times \cos(32°) ≈20.0\)
3. Use trigonometry to find x:
\( \sin(x°) = \frac{13}{17} \)
x ≈ 49,9° (use the reverse sin (shift, sin) function on the calculator)
