So the cost of 1950 bricks is $163.80.
For the given right rectangular prism,
Dimension = 8 in x 3\(\frac{1}{2}\) in x 3 in
Then,
Length = 8 in
Width = 3\(\frac{1}{2}\) in
Height = 3 in
Now find the volume of one brick by multiplying its length, width, and height together, so,
⇒ 8 in x 7/2 in x 3 in = 84 in³
Now calculate the total volume of 1950 bricks,
⇒ 1950 x 84 in = 163800 in³
Now we can find the total cost of the bricks by multiplying the total volume by the cost per cubic inch,
⇒ 163800 in x $0.10/in = $16,380.00
Finally, round our answer to the nearest cent,
we can divide by 100 and round to two decimal places,
⇒ $16,380.00 / 100 = $163.80
So the cost of 1950 bricks, rounded to the nearest cent, is $163.80.

an object is thrown upward at a speed of 156 feet per second by a machine from a height of 19 feet off the ground. the height of the object after seconds can be found using the equation h= -16t^2 +156t +5. When will the height 269feet?. When will the object reach the ground?
Solving the quadratic equation, we found that the object is at a height of 269 feet when t is 1.99s and 8.55s and the object reaches the ground when t = 9.78s.
What is a quadratic equation?
Any equation in algebra that can be written in standard form:
ax² + bx + c =0
where x stands for an unknown value, where a, b, and c stand for known values, and where a 0 is true is known as a quadratic equation.
The given equation of height h = -16t² + 156t +5
a) The time when the height is 269 feet can be found by substituting this value for h in the above equation.
h = -16t² + 156t +5
169 = -16t² + 156t +5
16t² - 156t + 164 = 0
Solving we get t = 8.55 s, 1.99s
b) The time when the object reaches the ground.
For this, we can take h = 0
-16t² + 156t +5 = 0
t = -0.03, 9.78
The negative value can be ignored.
Therefore solving the quadratic equation, we found that the object is at a height of 269 feet when t is 1.99s and 8.55s and the object reaches the ground when t = 9.78s.

a. Through what angle should the captain turn to head directly to Barbados?
b. Once the turn is made, how long will it be before the ship reaches Barbados if the same 15-knot speed is maintained?
Answer:
26.38° (nearest hundredth)
30.7960166... hours = 30 hours 47 mins 37 secs
Step-by-step explanation:
one knot = one nautical mile (nm) per hour
Therefore, 15-knot speed for 10 hours = 15 × 10 = 150 nm
Use cosine rule to find the distance between the ship and Barbados (blue dashed line on attached diagram).
Cosine rule: c² = a² + b² - 2ab cos(C)
Given:
a = 150b = 600C = 20°⇒ c² = 150² + 600² - 2(150)(600)cos(20°)
⇒ c² = 213355.3283...
⇒ c = 461.9040249... nm
Use sine rule to calculate smallest missing angle (red on attached diagram)
\(\sf \implies \dfrac{sin(A)}{150}=\dfrac{sin(20)}{461.9040249}\)
\(\sf \implies sin(A)=\dfrac{150sin(20)}{461.9040249}\)
\(\sf \implies A=6.376917848... \textdegree\)
Sum of interior angles of a triangle = 180°
⇒ missing interior angle (green) = 180° - 20° - 6.376917848...° = 153.6230822...°
Angles on a straight line sum to 180°
⇒ x° = 180° - 153.6230822...° = 26.376917848...°
The distance between the Ship and Barbados is 461.9040249 nm
Therefore, to calculate the time, divide the distance by the speed:
t = 461.9040249... ÷ 15 = 30.7960166... hours

Find a and b using the factor theorem.
\(f(x)=x^3+ax^2+bx-12\) has factor \((x-1), (x+1)\)
The values of a and b using the factor theorem for the polynomial f(x), we set f(1) and f(-1) equal to zero. Solving the resulting system of equations, we find that a = 12 and b = -1.
To find the values of a and b using the factor theorem, we need to use the given factors (x - 1) and (x + 1) and the fact that they are roots of the polynomial f(x).
The factor theorem states that if (x - c) is a factor of a polynomial, then f(c) = 0. Therefore, we can set x = 1 and x = -1 in the polynomial f(x) to get two equations.
First, let's substitute x = 1 into f(x):
f(1) = (1)^3 + a(1)^2 + b(1) - 12
f(1) = 1 + a + b - 12
Next, let's substitute x = -1 into f(x):
f(-1) = (-1)^3 + a(-1)^2 + b(-1) - 12
f(-1) = -1 + a - b - 12
Since (x - 1) and (x + 1) are factors, f(1) and f(-1) must equal zero. Therefore, we can set the two equations equal to zero and solve for a and b:
1 + a + b - 12 = 0
-1 + a - b - 12 = 0
Rearraning the equations, we have:
a + b = 11
a - b = 13
Now, we can solve this system of equations. Adding the two equations, we get:
2a = 24
a = 12
Substituting the value of a into one of the equations, we find:
12 - b = 13
b = -1
Therefore, the values of a and b are 12 and -1 respectively.

Answer:
1110 liters
Step-by-step explanation:
Let x = amount of 26% juice.
Amount of tomato juice:
740 liters of 36% juice contains 0.36(740) = 266.4 liters of tomato juice
x liters of 26% juice contains 0.26x liters of tomato juice
The result will be x + 740 liters of the juice blend at a concentration of 30%. It contains 0.3(x + 740) liters of tomato juice.
266.4 + 0.26x = 0.3(x + 740)

In circle O, secants ADB and AEC are drawn from external point A
such that points D, B, E, and C are on circle O. If AD = 8, AE = 6,
and EC is 12 more than BD, the length of BD is
(1) 6
(2) 22
(3) 36
(4) 48
The length of BD is 22.
In the given scenario, let's consider the following information.
AD = 8
AE = 6
EC is 12 more than BD.
To find the length of BD, we can utilize the Intercepted Arcs Theorem, which states that when two secants intersect outside a circle, the measure of an intercepted arc formed by those secants is equal to half the difference of the measures of the intercepted angles.
From the given information, we know that AD = 8 and AE = 6.
Since these are the lengths of the secants, we can use them to calculate the intercepted arcs.
First, let's find the intercepted arc corresponding to AD:
Intercepted Arc ADB = 2 \(\times\) AD = 2 \(\times\) 8 = 16
Similarly, we can find the intercepted arc corresponding to AE:
Intercepted Arc AEC = 2 \(\times\) AE = 2 \(\times\) 6 = 12
Now, we know that EC is 12 more than BD.
Let's assume the length of BD as x.
BD + 12 = EC
Now, let's consider the intercepted arcs theorem:
Intercepted Arc ADB - Intercepted Arc AEC = Intercepted Angle B - Intercepted Angle C
16 - 12 = Angle B - Angle C
4 = Angle B - Angle C.
Since Angle B and Angle C are vertical angles, they are congruent:
Angle B = Angle C.
Therefore, we can say:
4 = Angle B - Angle B
4 = 0
However, we have reached an inconsistency here.
The equation does not hold true, indicating that the given information is not consistent or there may be an error in the problem statement.
As a result, we cannot determine the length of BD based on the given information.

A restaurant on the top of a building is shaped like a circle with a radius of 80 feet. The restaurant rotate 60 degrees every 15 minutes. Two diners notice a bird that is sitting on a ledge outside of a window. If the bird stays on the ledge outside of a window, approximately how far will the bird travel in an hour?
Since, the restaurant rotates 60° every 15 minutes, then it will rotate 60°*4=240°
in one hour.
The full rotation of the restaurant is represented by 360°
Then,
\(\begin{gathered} \text{Circunference}=2\pi r \\ 2\pi r=2\pi\cdot80=160\pi \end{gathered}\)Having the length of the circunference, we know that 240° is only 2/3 from the full rotation, so the bird will travel in one hour:

FOIL: 3x - 9 + 8x = 10x +5

Suppose that a box contains 8 cameras and that 4 of them are defective. A sample of 2 cameras is selected at random. Define the random variable variable x as the number of defective cameras in the sample. What is the probability distribution for x?
The probability distribution for x is:
x P(x)
0 0.214
1 0.571
2 0.214
How can we determine the probability distribution for x?Since there are 8 cameras in the box, the total number of ways to choose 2 cameras from the box is given by the combination formula:
C(8,2) = 8!/(2!×(8-2)!) = 28
So there are 28 possible ways to choose a sample of 2 cameras.
Now, let's calculate the probability of each possible value of x:
When x = 0, both cameras in the sample are non-defective. The number of ways to choose 2 non-defective cameras from the 4 non-defective cameras in the box is given by the combination formula:
C(4,2) = 4!/(2!×(4-2)!) = 6
So the probability of x = 0 is:
P(x=0) = (number of ways to choose 2 non-defective cameras)/(total number of ways to choose 2 cameras)
= 6/28
= 0.214
When x = 1, one camera in the sample is defective and the other is non-defective. The number of ways to choose 1 defective camera from the 4 defective cameras in the box and 1 non-defective camera from the 4 non-defective cameras in the box is given by the product of the corresponding combinations:
C(4,1) × C(4,1) = 4×4 = 16
So the probability of x = 1 is:
P(x=1) = (number of ways to choose 1 defective camera and 1 non-defective camera)/(total number of ways to choose 2 cameras)
= 16/28
= 0.571
When x = 2, both cameras in the sample are defective. The number of ways to choose 2 defective cameras from the 4 defective cameras in the box is given by the combination formula:
C(4,2) = 4!/(2!×(4-2)!) = 6
So the probability of x = 2 is:
P(x=2) = (number of ways to choose 2 defective cameras)/(total number of ways to choose 2 cameras)
= 6/28
= 0.214
Therefore, the probability distribution for x is:

cos(0)=square root 3/3, sin 0<0. what is the value of sin0
Answer:
sin θ = \(\frac{\sqrt{6} }{3}\)
Step-by-step explanation:
Given that,
cos θ = \(\frac{\sqrt{3} }{3}\)
From the trigonometric functions,
cos θ = \(\frac{adjacent}{hypotenus}\)
⇒ adjacent = \(\sqrt{3}\), and the hypotenuse = 3
Let the opposite side be represented by x, applying the Pythagoras theorem we have;
\(/hyp/^{2}\) = \(/adj/^{2}\) + \(/opp/^{2}\)
\(/3/^{2}\) = \((\sqrt{3} )^{2}\) + \(x^{2}\)
9 = 3 + \(x^{2}\)
\(x^{2}\) = 9 - 3
= 6
x = \(\sqrt{6}\)
Thus, opposite side = \(\sqrt{6}\)
So that,
sin θ = \(\frac{opposite}{hypotenuse}\)
= \(\frac{\sqrt{6} }{3}\)
Therefore,
sin θ = \(\frac{\sqrt{6} }{3}\)
