Answer:
7
Step-by-step explanation:
Let x be the "integer." We'll assume it is odd.
The next consecutive odd integer would be x+2.
(2(x+2) - x) =9 [When an integer is subtracted from 2 times the next consecutive odd integer the difference is 9]
(2(x+2) - x) =9
(2x+4) - x) =9
x+4 =9
x = 5
The greater integer is x+2 or 7
Check:
If 5 is subtracted from 2 times the next consecutive odd integer, 7, is the difference 9?
2*7 - 5 = 9?
14 - 5 = 9?
14 - 5 = 9? YES
A heavy box is pulled across a wooden floor with a rope. The rope forms an angle of 60.0° with the floor. A tension of 80.0 N is maintained on the rope. What are the horizontal and vertical components of the force?
The vertical component of the force is 69.28 N and the horizontal component of the force is 40 N.
What is the resolution of the forces?Resolution of forces is the process of separating a force into two or more pieces so that the combined effect on the body is the same as if it had been a single force. We can analyze motion individually in different directions thanks to the resolution of forces.
Given that a heavy box is pulled across a wooden floor with a rope. The rope forms an angle of 60.0° with the floor. A tension of 80.0 N is maintained on the rope.
The vertical component and the horizontal component will be calculated as:-
Vertical component = 80sin60=69.28 N
Horizontal component = 80cos60 = 40 N
Therefore, the vertical component of the force is 69.28 N and the horizontal component of the force is 40 N.

[tex]2x = 76[/tex]
Due to alternate angles
[tex] \frac{2x}{2} = \frac{76}{2} \\ x = 38[/tex]
40°+(y-8)°+76°=180°(sum of angles in a triangle)
[tex]40 + y - 8 + 76 = 180 \\ y + 108 = 180 \\ y = 180 - 108 \\ y = 72[/tex]
ATTACHED IS THE SOLUTION.
Answer:
x = 38 ; y = 72
Step-by-step explanation:
180 = 76 + 40 + (y - 8)
180 = 108 + y
72 = y
The triangle has parallel lines, so the uppermost right angle is also 90 degrees.
90 - 76 = 14
180 = 90 + 14 + 2x
180 = 104 + 2x
76 = 2x
38 = x
An acorn fell from a branch 20 feet high and landed on a branch 7 feet high. How long did it
take the acorn to fall?
It will take 1.62 seconds for an acron to fall on the branch of 7 feet high.
What is defined as the speed of object?The definition of speed is the rate at which an object's position changes in any direction. Speed is defined as the ratio of distance traveled to time spent traveling. Because it has only one direction and no magnitude, speed is a scalar quantity.For the given question,
An acorn fell from a branch 20 feet high.
An acorn landed on a branch 7 feet high.
The total distance travelled by and acron is 20 - 7 = 13 feet.
Let the final velocity of an acron is 'v'.
The initial velocity of an acron 'u' is zero.
Using third equation of straight line.
v² = u² + 2gsu = 0g = 9.8 /sec²s = 13 feetPut the values.
v² = 2×9.8×13
v = 15.96 ft/sec
Put the value in first equation of straight line.
v = u + gt
15.96 = 0 + 9.8×t
t = 15.96/9.8
t = 1.62 seconds.
Thus, it will take 1.62 seconds for an acron to fall on the branch of 7 feet high.

Answer:
correct me if im wrong but my answer is x=7, or in other words, 7.
Step-by-step explanation:
Answer:
7 years old
Step-by-step explanation:
You would start by going backward. If 13 is 8 less, then you would first add 8. You would have 21. Now all you have to do is divide by three. So your answer would be 7. If you would want to check you could plug it back in. 7 multiplied by 3 is 21. 21 - 8=13

Can you write a quadratic function that does not have a y-intercept?
Answer:
The graph of a quadratic function will always have one y-intercept
Step-by-step explanation:
Pick one of the remaining choices and explain on the lines below, why thatchoice contains two expressions that are not equivalent for any value of r.
If two expressions have the same coefficients of the variable, then the variable can be any number
For the first choice
3(3r + 3) = 9r + 9 === 1st expression
6r + 6 ===== 2nd expression
If we equate them
9r + 9 = 6r + 6
If we solve the equation we will find just one value of r
9r + 9 - 6r = 6r - 6r + 6
3r + 9 = 6
3r + 9 - 9 = 6 - 9
3r = -3
r = -1
But in the other choices, the two expressions have the same coefficients of r
Then when we equate them they will cancel each other
Then r can be any value
Because it does not affect the equation

Jack wants to eat 2 1/5 of his plate in 1/3 hour. The first step is to convert 2 1/5 to improper fraction. It becomes 11/5
The statement would be
Jack wants to eat 11/5 of his plate in 1/3 hour.
Let x represent how much of his plate that he will eat in 1 hour. Therefore
11/5 = 1/3
x = 1
By cross multiplying, it becomes
x * 1/3 = 1 * 11/5
x/3 = 11/5
x = 11/5 * 3
x = 33/5
Converting to mixed fraction, it becomes

si cada 8.33 minutos me dan 10 dolares cuantos dolares tendria en 6 horas ademas cuantos dolares ganaria cada 30 minutos
The payment for each 6 h is equal to $ 432.2 while the payment for each 30 min would be $ 36.01.
Rule of ThreeIt's a math tool for solving problems about proportion. You can relate more than 2 variables and from the proportion, it's possible to find an unknown number.
Conversion Unit TimeIn the International System Units (SI), the standard unit for time is the second (s). For solving any exercise, you need to know the relation between the units of the time. See below:
1h=60 min = 3600s
1 min = 60 s
Now you can solve the question from the rule of three for finding the payment in dollars.
The question gives: an each 8.33 min, the payment is 10 dollars. Thus, from this relation you can write:
For 6 hFirst, you should convert 6h to minutes, then,
1 h ----- 60 min
6h ----- x
x=60*6=360 min
After that, you should apply the rule of three for finding the payment in dollars.
8.33 min ----- 10 dollars.
360 min ------- x
8.33x=360*10
8.33x=3600
x= $ 432.2
For 30minYou should apply the rule of three for finding the payment in dollars.
8.33 min ----- 10 dollars.
30 min ------- x
8.33x=30*10
8.33x=300
x= $ 36.01

What is meant by differential equation?A differential equation in mathematics exists an equation that links the derivatives of one or more unknown functions. Applications often involve functions that reflect physical quantities, derivatives that depict the rates at which those values change, and a differential equation that establishes a connection between the three.
A differential equation in mathematics is an equation that includes one or more functions and their derivatives. The rate of change of a function at a place is determined by the derivatives of the function. It is mostly employed in disciplines like physics, engineering, biology, and others.
There exists at least a couple of ways to work this. One exists to write the equation for the distance between the cyclists and differentiate it.
d² = (3900 + 32t)² + (5200 + 24t)²
simplifying the above equation, we get
(2d)d/dt = 2(3900 + 32t)(32) +2(5200 + 24t)(24)
At t = 0,
dd/dt = (32·3900 + 24·5200)/√(3900² + 5200²)
simplifying the above equation, we get
= (124800 + 124800)/√(15210000 + 27040000)
= 249600/6500 = 38.4 meters per second
Therefore, the distance between the two cyclists changing exists 38.4 meters per second.

What is termed as the constant rate?In math, a constant rate is the exclusion of acceleration. A function with such a constant rate, in general, has a second derivative of 0. The function would be a straight line if plotted on standard graph paper because the change in y (or rate) would've been constant.
