g components of force f with respect to x and y axes can be calculated as follow. please note that x and y axes are not perpendicular to each others. the angle between f and x is denote as (theta). the angle between f and y is denote as (gamma).
The force with respect to the x and y axes can be calculated as follows:
F_x = 100N cos(30) = 86.6N
F_y = 100N sin(60) = 50N
Let F be the magnitude of the force, (theta) be the angle between the force and the x-axis, and (gamma) be the angle between the force and the y-axis. The components of the force with respect to the x and y axes can be calculated using the following formulas:
F_x = F cos(theta)
F_y = F sin(gamma)
For example, if the magnitude of the force is 100N and (theta) = 30 degrees and (gamma) = 60 degrees, then the components of the force with respect to the x and y axes can be calculated as follows:
F_x = 100N cos(30) = 86.6N

The inequality for the number of lawns he needs to mow is: $50 < $20 + $5n
The correct answer is an option (b)
Let n represents the number of lawns he needs to mow.
Here, Billy needs to make more than $50 between his allowance and the lawns that he mows. This means that an inequality should include 50 <
As Billy will make $5 for each lawn that he mows, for 'n' number of lawns the cost would be = 5n
Based on the mentioned conditions we formulate an inequality,
50 < 20 + 5n
20 + 5n > 50
20 + 5n - 20 > 50 - 20 ...........(subtract 20 from each side)

The label on a car's antifreeze container claims to protect the car at temperatures greater than −40°C and less than 140°C. To convert Celsius temperature to Fahrenheit temperature, the formula is C equals five ninths times the quantity F minus thirty two.. Write a compound inequality to determine the Fahrenheit temperature range at which the antifreeze protects the car
Answer:
-40F to 284F
Step-by-step explanation:
C = 5/9F -32
so F = 32+9/5*C
so the range is
F= 32+9/5*(-40) = 32-72 = -40F
F= 32+9/5*(140) = 32+252 = 284F

at a certain bakery, the price of each doughnut is $1.50. let the random variable d represent the number of doughnuts a typical customer purchases each day. the expected value and variance of the probability distribution of d are 2.6 doughnuts and 3.6 (doughnuts)2, respectively. let the random variable p represent the price of the doughnuts that a typical customer purchases each day. which of the following is the standard deviation, in dollars, of the probability distribution of p?
The standard deviation, in dollars, of the probability distribution of p is √(1.50 × 3.6) dollars.
We are given the following parameters -
Expected value = 2.6
Variance = 3.6
Price per doughnut = $1.50
Now we can write the price for the variance of the distribution as -
Price per doughnut × Variance
Variance = $1.50 × 3.6
The formula for the standard deviation of the distribution D in relation to the variance is given by -
Standard deviation = √variance
Standard deviation = √(1.50 × 3.6)
Therefore, the standard deviation of P in dollars will be √(1.50 × 3.6).

Find the length of the midsegment of the trapezoid with the vertices S(-2,4) ,T(-2,-4) ,U(3,-2) ,V(13,10)
11.69 is the exact length needed for the mid-segment of the trapezoid with STUV vertices.
What is trapezoid?The Greek roots of the term trapezoid are trapeza, which means "table," and -oeides, which means "formed." A trapezoid is shaped like a table. It has two parallel sides, which are often referred to as the figure's bases. Take the average of the bases and multiply it by the height to determine the area of a trapezoid.
According to question:We have,
vertices S(-2,4) ,T(-2,-4) ,U(3,-2) ,V(13,10).
Half of the lengths of the two parallel sides, ST and UV, make up the length of the trapezoid's middle section.
The trapezoid's vertices are S(2, 4), T(2, 4), U(3, 2), and V. (13, 10).
The distance formula is then used to calculate the length of the ST and UV sides;
Length = [tex]\sqrt{x_{2}-x_{1}+y_{2}-y_{1}}[/tex]
Side ST's length is S(-2, 4), T(-2, -4).
ST = [tex]\sqrt{x_{2}-x_{1}+y_{2}-y_{1}}[/tex]
ST = [tex]\sqrt{(-2-(-2))^2+(-4-(4))^2[/tex]
ST = [tex]\sqrt{0 + 64}[/tex]
ST √64
ST = 8
Side UV's length is U(3, 2), V. (13, 10).
UV = [tex]\sqrt{(13-3)^2+(10-(-2))^2[/tex]
UV = [tex]\sqrt{(10)^2+(12)^2[/tex]
UV = √244
UV = 15.62
Therefore,
The mid-segment STUV's length is,
Length of mid-segment = (ST + UV)/2
Length of mid-segment = (8 + 15.62)/2
Length of mid-segment = (23.62)/2
Length of mid-segment = 11.81
Therefore, 11.69 is the exact length needed for the mid-segment of the trapezoid with STUV vertices.

The client should invest $8889 in AAA bonds, $4444 in A bonds, and $5667 in B bonds.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example: 2x + 4 = 8 is an equation.
We have,
Amount invested in AAA bond = 2x
Amount invested in A bond = y
Amount invested in B bond = x
Now,
Average yield:
AAA bond = 4%
A bond = 5%
B bond = 8%
Now,
Total amount = $19,000
Total yield = $990
Now,
Two equations can be made:
2x + y + x = 19000
3x + y = 19000 _____(1)
0.04 x (2x) + 0.05 x y + 0.08x = 990
0.08x + 0.05y + 0.08x = 990
0.16x + 0.05y = 990 ______(2)
From (1) and (2),
3x = 19000 - y
x = (19000 - y)/3
Substituting in (2)
0.16 x (19000 - y)/3 + 0.05y = 990
0.053 x 19000 - 0.053y + 0.05y = 990
1007 - 0.003y = 990
1007 - 990 = 0.003y
y = 17/0.003
y = 5666.6
y = 5667
Now,
x = (19000 - y)/3
x = (19000 - 5667)/3
x = 4444.333
x = 4444
Now,
x = $4444
y = $5667
2x = $8889
Thus,
Amount invested in AAA bond = $8889
Amount invested in A bond = $5667
Amount invested in B bond = $4444

The floor of a rectangular room is to be covered with tiles 1-foot sides. The floor of the room is 18 feet long and 12 feet wide. How much would it cost at $4 a tile?
The cost for the flooring of the rectangular room is $864.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Given that,
Dimension of each time = 1 foot
Length of the room = 18 feet
Width of the room = 12 feet
Number of tiles needed for the room = 18 × 12 = 216
Cost of one tile = $4
Total cost for the tile = 216 × $4 = $864
Hence the total cost for the tiles is $864.

In the pattern below, the cat moves clockwise through the four squares, and the mouse moves counterclockwise through the eight exterior segments of the four squares.
If the pattern is continued, where would the cat and mouse be after the 247th move?
Only setup A places the mouse on the bottom right square and the cat there.
The pattern is continued, so we have to define where the cat and mouse would be after the 247th move.
Divide the issue into two parts: the location of the mouse and the location of the cat after the 247th move.
Every cycle, which consists of four different positions for the cat, is repeated once every four movements. When 247 is divided by 4, the remainder is 3. This matches the bottom right corner, where the cat is located after the third move.
Similar to the mouse, which repeats every eight moves, the mouse has eight possible places in a single cycle. When 247 is divided by 8, the remainder is 7. This matches the rat's bottom left corner position after the seventh motion.
The only configuration with the cat in the bottom right square and the mouse in that position is A.

en almacén 8, cuesta 1200 y bajan el 4%; en el último almacén cobran 1500 y hacen el 2% de
rebaja.
De acuerdo con lo anterior, la respuesta correcta serían 270,000 es el precio más bajo que obtuvo para comprar un motor generador de ondas estacionarias para cuerdas en el primer almacén.
¿Cómo calcular cuál almacén le ofrece el precio más bajo a Juan?
Para calcular cuál es el almacén que le ofrece el precio más bajo a Juan debemos identificar a cuanto equivale el descuento y restarlo del precio total. Cuando sepamos el precio final comparamos para saber cuál de todos es el menor.
300,000 / 100 = 3,000
3,000 * 10 = 30,000
300,000 - 30,000 = 270,000
400,000 / 100 = 4,000
4,000 * 14 = 56,000
400,000 - 56,000 = 344,000
500,000 / 100 = 5,000
5,000 * 20 = 100,000
500,000 - 100,000 = 400,000
700,000 / 100 = 7,000
7,000 * 22 = 154,000
700,000 - 154,000 = 546,000
750,000 / 100 = 7,500
7,500 * 12 = 90,000
750,000 - 90,000 = 660,000
800,000 / 100 = 8,000
8,000 * 10 = 80,000
800,000 - 80,000 = 720,000
1'000.0000 / 100 = 10,000
10,000 * 6 = 60,000
1'000.000 - 60,000 = 940,000
1'200.000 / 100 = 12,000
12,000 * 4 = 48,000
1'200,000 - 48,000 = 1'152.000
1'500.000 / 100 = 15,000
15,000 * 2 = 30,000
1'500,000 - 30,000 = 1'270,000
De acuerdo a lo anterior, el precio más bajo para comprar un motor generador de ondas estacionarias para cuerdas es 270,000 en el primer almacén.
