Which inequality represents all the solutions of -2(3x + 6) ≥ 4(x + 7)?
A. x ≥ -4
B. x ≤ -4
C. x ≥ 8
D. x ≤ 8
The inequality that represents the solution of -2(3x + 6) ≥ 4(x + 7) is x ≤ -4, the correct option is B.
What is an Inequality?An inequality is a statement that is formed when two expressions are joined using an inequality operator.
The inequality is -2(3x + 6) ≥ 4(x + 7)
To find the solutions, the inequality has to be simplified.
Solving the inequality by using Distributive Property,
-6x -12 ≥ 4x +28
Adding (+12) on both sides of the inequality
-6x ≥ 4x +28 +12
Adding (-4x) on both the sides of the inequality
-6x + (-4x) ≥ 40
-10x ≥ 40
Dividing 10 on both the sides
-x ≥ 4
Reversing the sign of the inequality to remove the negative sign of x
x ≤ -4

Adam must fly home to city A from a business meeting in city B. One flight option flies directly to city A from B, a distance of about 467.3 miles. A second flight option flies first to city C and then connects to A. The bearing from B to C is N28.7E, and the bearing from B to A is N60.7E. The bearing from A to B is S60.7W, and the bearing from A to C is N79.1W. How many more frequent flyer miles will Adam receive if he takes the connecting flight rather than the direct flight?
Answer:
The value is [tex] k =109.6 \ miles [/tex]
Step-by-step explanation:
The diagram illustrating the question is shown on the first uploaded image
From the question we are told that
The distance from city A to B is AB = 467.3 miles
The bearing from B to C is [tex]\theta_{BC} = N 28.7E[/tex]
The bearing from B to A is [tex]\theta_{BA} = N 60.7E[/tex]
The bearing from A to B is [tex]\theta_{AB} = S60.7W[/tex]
The bearing from A to C is [tex]\theta_{AC} = S79.1W[/tex]
Generally from the diagram
[tex]\theta_A = 180 - 60.7 -79.1[/tex]
=> [tex]\theta_A = 40.2 ^o[/tex]
Also
[tex]\theta_B = 32^o [/tex]
and
[tex]\theta_C = 180 - (\theta_A +\theta_B )[/tex]
=> [tex]\theta_C = 180 - (40.2 + 32 )[/tex]
=> [tex]\theta_C = 107.8 ^o[/tex]
Generally according to Sine Rule
[tex]\frac{BC}{sin (\theta_A)} = \frac{CA}{sin (\theta_B)} =\frac{AB}{sin (\theta_C)}[/tex]
=> [tex]\frac{BC}{sin (40.2)} = \frac{CA}{sin (32)} =\frac{467.3 }{sin (107.8)}[/tex]
So
[tex]\frac{BC}{sin (40.2)} = \frac{467.3 }{sin (107.8)}[/tex]
=> [tex]BC = 316.8 \ miles[/tex]
Also
[tex]\frac{CA}{sin (32)} = \frac{467.3 }{sin (107.8)}[/tex]
[tex]CA = 260 .1 \ miles [/tex]
Generally the additional flyer miles that Adam will receive if he takes the connecting flight rather than the direct flight is mathematically represented as
[tex]k = [CA +BC] - AB [/tex]
=> [tex] k = [260 .1 +316.8]- 467.3 [/tex]
=> [tex] k =109.6 \ miles [/tex]
A teacher has a large container of blue, red, and green beads. She reports to the students that the proportion of blue beads in the container is 0. 30. The students feel the proportion of blue beads is lower than 0. 30. A student randomly selects 60 beads and finds that 12 of the beads are blue. The P-value for the test of the hypotheses, H0:p=0. 30 and Ha:p<0. 30, is 0. 45. What is the correct interpretation of this value?
There is a 4. 5% chance the proportion of blue beads in the container is 0. 3.
Assuming the true proportion of blue beads in the container is 0. 30, there is a 4. 5% probability that the null hypothesis is true.
Assuming the true proportion of blue beads in the container is 0. 30, there is a 4. 5% probability that the sample proportion would be 0. 20 or less by chance alone.
Assuming the true proportion of blue beads in the container is less than 0. 30, there is a 4. 5% probability that the sample proportion would be 0. 20 or less by chance alone
Answer: C
Step-by-step explanation:
P - Value
Is the evidence against the null hypothesis.
The lower the p-value, the greater the chance of rejection of the null hypothesis.
The greater the p-value, the greater the chance to accept the null hypothesis.
So, in other words, the question asks the probability of having accepted a null hypothesis.
So using the above statement we can say that statement C is true.
What is the value of y?
A. 120°
B. 66°
C. Cannot be determined
D. 60°
Answer:
60
Step-by-step explanation:
all sides are equal
The value of y is 60. so the answer is D. 60°.
In a triangle, the sum of all angles is always 180 degrees.
If two angles of a triangle are 60 degrees each, the third angle can be found by subtracting the sum of the other two angles from 180 degrees.
So, the third angle would be:
60 + 60 + y = 180
y = 180° - 60° - 60°
y = 60°
Therefore, the value of the third angle, which is represented by y in this case, is 60°.
Therefore, correct answer is D. 60°.

At the amusement park, the Ferris wheel is located 95 feet east and 156 feet north of the entrance. The swings are located 23 feet west and 124 feet north of the entrance. If Jalen is standing exactly three-eights the distance from the Ferris wheel to the swings, to the nearest hundredth of a foot, find the direct distance between Jalen and the entrance. (Round your answer to the nearest tenth)
Answer:
120.62 feet
Step-by-step explanation:
Let the entrance be the origin (0,0). If the Ferris wheel is located 95 feet east and 156 feet north of the entrance, its coordinates are (95, 156). If the swings are located 23 feet west and 124 feet north of the entrance, its coordinates are (-23, 124).
We now find the distance from the swing to the Ferris wheel which for a pair of coordinates (x₁, y₁) and (x₂, y₂) is gotten from d = √[(x₂ - x₁)² + (y₂ - y₁)²] where (x₁, y₁) = (-23, 124) and (x₂, y₂) = (95, 156).
So, d = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(95 - (-23))² + (156 - 124)²]
= √[(95 + 23))² + (156 - 124)²]
= √[(118)² + (32)²]
= √[13924 + 1024]
= √14948
= 122.26 feet
Since Jalen is standing exactly three-eights the distance from the Ferris wheel to the swings, his distance from the Ferris wheel is d' = 3d/8 = 3 × 122.26/8 = 45.85 feet
To find the coordinates (x', y') of Jalen's point from the entrance, we subtract his distance from the Ferris wheel from the coordinates of the point of the Ferris wheel. So, (x', y') = (95 - 45.85, 156 - 45.85) = (49.15, 110.15).
So, Jalen's distance from the entrance is gotten from
d = √[(x₂ - x₁)² + (y₂ - y₁)²] where (x₁, y₁) = (0, 0) and (x₂, y₂) = (49.15, 110.15).
So, d = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(49.15 - 0)² + (110.15 - 0)²]
= √[(49.15)² + (110.15)²]
= √[2,415.7225 + 12,133.0225]
= √14,548.745

Answer:
x = 15
Step-by-step explanation:
The given angles are same- side interior angles and are supplementary, thus
6x + 7 + 3x + 38 = 180, that is
9x + 45 = 180 ( subtract 45 from both sides )
9x = 135 ( divide both sides by 9 )
x = 15
Answer:
x = 15
Step-by-step explanation:
these two angles are actually supplementary, which means they add up to 180.
using this, you can make this equation:
3x + 38 + 6x + 7 = 180
combine like terms.
3x + 6x + 38 + 7 = 180
9x + 45 = 180
subtract 45 from both sides.
9x = 135
divide both sides by 9
x = 15

Kevin wrote a total of 12 pages over 3 hours. How many hours will Kevin have to spend writing this week in order to have written a total of 20 pages? Assume the relationship is directly proportional.
Answer:
It will take him 5 hrs to write a 20-page essay because he can write 4 pages in 1 hour.
Hope this helps!
Answer:
5 hours
Step-by-step explanation:
For 12 pages, he spent 3 hours. So it takes him 1 hour to write 4 pages. (12 ÷ 3 = 4) If for each 4 pages 1 hour is spent respectively, then for 20 pages: 20 ÷ 4 = 5 hours will be spent.
The Nike factory has just finished up a new order of Air Jordan XIII sneakers to be released soon. They just produced 5,814 new pairs of the sneakers. If the company wants to evenly distribute the sneakers evenly among their 17 warehouses, how many pairs of the Air Jordan sneakers will each warehouse receive?
Answer:
342 pairs
Step-by-step explanation:
Given that,
New pair of sneakers produced by the Nike factory = 5,814
The company wants to distribute the sneakers evenly among their 17 warehouses.
We need to find the no of pairs of the Air Jordan sneakers will each warehouse receives. It can be calculated as follows :
[tex]n=\dfrac{\text{total pair of sneakers}}{\text{no of warehouses}}\\\\n=\dfrac{5814}{17}\\\\n=342[/tex]
It would mean that each warehouse will receive 342 pair of sneakers.
