The equation which could be used to find the value of x is; cos 49° = x over 55; option A.
What is an equation?An equation is an expression which is used to show the relationship between two or more terms and this relationship is that the terms are equal.
An equation has two sides, the left hand side and the right hand side. An equation also contains an equal sign.
If an unknown variable is present in one or more of the sides, the value of that unknown can be found algebraically.
In the given question, the triangle DEF is a right-angled triangle, where angle E is a right angle.
The side DF measures 55, the side DE measures x, and the angle D measures 49°.
This follows that the the hypotenuse is DF and the adjacent side is D.
Using the trigonometric ratios;
cos θ = adjacent/hypotenusewhere θ = 49°
cos 49° = x/55
x = cos 49° * 55
x = 36
In conclusion, the value of x is obtained by using trigonometrical ratios.

Mary and Keisha run with the same constant speed but in opposite directions. The girls have: A. The same position B. Different accelerations C. Different speeds D. Different velocities
Answer:
D
Explanation:
Mary and Keisha run with the same constant speed but in opposite directions. The girls have different velocities. Hence option D is correct.
What is velocity?According to a particular point of view and a particular unit of time, velocity is the rate at which an object changes position while travelling in one direction. Velocity is a vector quantity. It has both a magnitude and a direction. Therefore, it alters whenever either the speed or the direction do. The meter per second is the accepted unit of magnitude for velocity.
One might refer to an object as accelerating if either the magnitude or direction of the velocity vector changes. An object moving in a circle at a constant speed can be said to accelerate because the direction of the velocity changes. Although the object is moving at a constant speed, its velocity is changing. As a vector, velocity has a fixed magnitude but a fluctuating direction.
Thus, Mary and Keisha run with the same constant speed but in opposite directions. The girls have different velocities. Hence option D is correct.

Psychology What is one source error associated with self-report inventories, and what is one of its solutions?
Answer:
one source error associated with self-report inventories is that some people aren't very self-aware or may jump to conclusions about their systems or disorders without taking a step back and assessing all of the possibilities. a solution to this would be having the assessment taker speak to a professional, or trying to make them report their symptoms as objectively as possible.
Explanation:
Answer:
One source error is deliberate deception, and one of its solutions is having a lie scale inserted into the assessment. Another source error is social desirability, and one of its solutions is locating questions sensitive to bias and changing or dropping them. Another source error is response set, and two of its solutions are using word variations and writing questions on the assessment in different ways.

THIS IS MY EXAM FOUR QUESTIONS CAN SOMEBODY PLZZ HELP ME AN SHOW THE WORK FROM THE BOTTOM OF MY HEART PLZZ
Answer:
Answer of question 1 :
Explanation:
Let x be the legs of ducks
And y be the legs of cows
According to the question,
2x + 4y = 52...…..(i) ( as ducks ahs two legs and as cows has 4 legs)
As he has 21 animals in total so,
x + y = 21...…..(ii)
We have make the equation. We will solve them by eliminatory method or substitution method. Here, I'll go for substitution method.
From equation (ii)
x = 21 - y....…..(iii)
Putting the value of x in equation (i),
2x + 4y = 52
2( 21 - y ) + 4y = 52
42 - 2y + 4y = 52
2y = 52 - 42
y = 10/2
y = 5 ( He has 2 cows)
putting the value of y in equation (ii)
x + y = 21
x + 5 = 21
x = 21 -5
x = 16 ( He has 16 ducks)

Bakari is making a scale model of a large cylindrical building. The scale model has a volume that
of the building. To determine the radius and height of the scale model, Bakari divided both the ra
by 8 because the formula for the volume of a cylinder only has 2 variables.
Which statement is true?
Bakari is correct.
Bakari is incorrect. He should have divided the radius and height by 2.
Bakari is incorrect. He should have divided the radius and height by 4.
Bakari is incorrect. He should have divided the radius and height by 16.
Answer: Bakari is correct
Explanation:
Bakari is correct. If he divided both the radius and height by the same factor (in this case, 8), then the resulting scale model will have the same proportions as the original building, just scaled down by a factor of 8. The formula for the volume of a cylinder is V = πr²h, which only has two variables (the radius and height). So if Bakari wants to maintain the same proportions of the cylinder in his scale model, he needs to divide both the radius and height by the same factor. This will result in a scale model with a volume that is 1/8th the volume of the original building.

Marisol is selling snacks at her school’s soccer games to raise money for a service project. She buys nuts in cases that contain 24 bags and granola bars in cases that contain 20 packages. She sells the nuts for $1.25 a bag and the granola bars for $1.75 a package. If she raised $160 and sold 112 items, how many cases of granola bars did Marisol buy?
Answer:
2 cases of granola bars
Explanation:
This is a classic system of equations type question.
24n + 20gb = 112 as she can only buy the items in these quantities and this is how many she bought in total
30n + 35gb = 160 as this is how much money she earns per case
I like to solve using elimination when possible. So we can multiply the first equation by 1.25
30n + 25gb = 140 then subtract this from the second equation
10 gb = 20 then divide by 10
gb = 2
