300 is divided into 4 parts such that the first integer number is twice the second, three times the third
and four times the fourth. What is the value of the largest of these numbers?
Answer:
x = 144
Step-by-step explanation:
300 = x + [tex]\frac{1}{2}[/tex]x + [tex]\frac{1}{3}[/tex]x + [tex]\frac{1}{4}[/tex]x
300 = [tex]\frac{12}{12}x+\frac{6}{12}x+\frac{4}{12}x+\frac{3}{12}x[/tex]
300 = [tex]\frac{25}{12} x[/tex]
[tex]x=(300)(\frac{12}{25} )[/tex]
x = 144
To check if the answer is right:
300 = 144 + [tex]\frac{1}{2}[/tex](144) + [tex]\frac{1}{3}[/tex](144) + [tex]\frac{1}{4}[/tex](144)
300 = 144 + 72 + 48 + 36
300 = 216 + 84

The perimeter of the rectangle is given by 4x+2.
The area of a rectangle is given by the formula A=l*w where l is the length and w is the width. In this case, the area is given by the equation x^2 + x - 6. To find the perimeter of the rectangle, we need to know the length and width. However, since the area is represented by an equation, we do not have a specific value for the length and width. The given equation x^2 + x - 6 is a quadratic equation which can be factorised as (x-2)(x+3). So, we can't find the length and width without the value of x. To find the perimeter of a rectangle we use the formula P=2(l+w). If we know the value of x, we can find the perimeter of rectangle.

ship and the buoy at the time of each sighting.
5. The angle of depression from a helicopter to its landing port is 64º. If the altitude of the helicopter is 1600
meters, find the direct distance from the helicopter to the landing port.
The correct answer for the given questions is 26.82 km and 780.372 km respectively.
4. To find the distance between the ship and the buoy at the time of each sighting, we can use the principle of non-collinearity of the ship, buoy, and observer.
Let x be the distance between the ship and the buoy at the time of the first sighting and y be the distance between the ship and the buoy at the time of the second sighting.
The angle of bearing from the ship to the buoy is S46°E, which is equivalent to (180 - 46) = 134° from the North.
The angle of bearing from the ship to the buoy at the second sighting is S12°E, which is equivalent to (180 - 12) = 168° from the North.
Therefore, the angle between the two lines of bearing is 168 - 134 = 34°.
Thus, 15/x= tan 34°
=> x= 15/tan 34°
=>x= 22.28 m
And, 15/y= sin 34°
=> y= 15/sin 34°
=> y= 26.82 km
5. To find the direct distance from the helicopter to the landing port, we can use the tangent function.
Let d be the direct distance from the helicopter to the landing port.
The angle of depression is 64°, and the altitude of the helicopter is 1600 meters.
tan(64) = 1600/d

What is the slope of y =- 1?
The slope of y = -1 is m = zero.
Now, According to the question:
What is slope and example?
Whenever the equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation. The m is the slope of the line. And b is the b in the point that is the y-intercept (0, b). For example, for the equation y = 3x – 7, the slope is 3, and the y-intercept is (0, −7).
So,
We define slope as :
[tex]m = \frac{y_1-y_0}{x_1-x_0}[/tex]
In a constant function as given :
y = -1
We have,
[tex]y_1=y_0=-1[/tex]

They now wonder if they can assess the participants more quickly (50 hours of observations is a lot to gather and code). They draw up a survey of 50 questions and ask all the mothers to answer the questions. The researchers hope that the scores on the survey will mirror the scores on the observations. Here are the trials: Participant 1: Observation: 10 (very low). Survey: 11 (very low) Participant 2: Observation: 25 (moderate). Survey: 26 (moderate) Participant 3: Observation: 37 (high) Survey: 39 (high) The survey is A. Reliable but not valid B. Valid but not reliable C. Neither reliable nor valid D. Both reliable and valid
D). The survey is both reliable and valid which means the survey is consistent.
Reliability is the consistency of the results, so if the survey and observation scores are close together, then the survey is reliable. In this case, the scores on the survey and the observations were very close for all three participants, suggesting that the survey is reliable.
Validity is the accuracy of the results, so if the survey and observation scores accurately reflect the true quality of the mother-child relationship, then the survey is valid.
In this case, the scores for all three participants were within the range of 10-50, which suggests that the scores from the survey accurately reflect the true quality of the mother-child relationship and are therefore valid.

The area of the lateral surface of the net Christine is using to create a triangular prism is about 42.8 cm²
What is a triangular prism?A triangular prism is a polyhedron that has three rectangular faces, joined head to head together to form a closed loop, to which are attached two triangular faces on their sides.
The dimensions of the triangular prism are;
Dimensions of the lower right triangle; 7 cm, 2 cm
Width of the slant surface = 2 cm
Taking the length of the rectangular slant surface as the length of the hypotenuse side of the right triangle above, and using Pythagorean Theorem to find the length, we get;
The square of the length of the hypotenuse of the right triangle = 7² + 2² = 53
Length of the hypotenuse of the right triangle with side lengths of 2 cm and 7 cm = √(53) cm
Length of the side of the rectangular slant surface of the triangular prism = √(53) cm
Area of a rectangle = Length × Width
Area of the upper rectangular slant surface of the prism = √(53) × 2 ≈ 14.6
The lateral surface area, A, of the figure is therefore;
A = Area of the two right triangles + Area of the two rectangles
Area of a triangle = (1/2) × Base length × Height
A = (1/2) × √(53) × 2 + (1/2) × 7 × 2 + √(53) × 2 + 7 × 2 ≈ 48.8

This relationship can be represented by the equation y=59+6xy=59+6x, where yy represents the expected quiz score and xx represents hours spent on homework that week. What could the number 59 represent in the equation?
The number 59 in the equation y = 59 + 6x represents the y-intercept of the equation.
The y-intercept is the point at which the line of best fit (in this case, the line representing the relationship between time spent on homework and quiz scores) crosses the y-axis. In other words, it is the value of y when x = 0.
In this equation, when x = 0, y = 59, which means that even if a student spends 0 hours on homework that week, their expected quiz score would be 59. This value could represent a baseline score or an average score for students who spend no time on homework.

The sum of the reciprocals of two consecutive odd integers is 12/35. Find the two integers.
The two consecutive odd integers are 9 and 11. 1/8 plus 1/11 equals 12/35.
The sum of the reciprocals of two consecutive odd integers is 12/35.
1/x + 1/(x+2) = 12/35
(x+2)/(x*35) + (x/35) = 12/35
x + 2 + x = 12
2x = 10
x = 5
5 and 7 are the next two odd numbers.
The sum of the reciprocals of two consecutive odd integers is 12/35. To find the two integers, we need to solve for x. Since the two integers are consecutive and odd, the equation
1/x + 1/(x+2) = 12/35
can be used to find x. We can then multiply both sides of the equation by x*35 and simplify it to (x+2)/(x*35) + (x/35) = 12/35.
By subtracting x/35 from both sides and then adding 2 to both sides, we can get the equation
x + 2 + x = 12.
By solving the equation 2x = 10, we find that x = 5. This means that the two consecutive odd integers are 5 and 7. This can also be verified by checking that 1/5 + 1/7 is equal to 12/35.
