If a body is moving in the horizontal axis with a velocity Vx= 6m/s and in the vertical axis Vy=8m/s, the magnitude of the velocity of the body V is 10
The given parameters are;
The velocity of the body relative to the horizontal axis, vₓ = 6 m/s
The velocity of the body relative to the vertical axis, = 8 m/s
Required;
The measure of the magnitude of the velocity of the moving body, v
The velocity of the body can be represented vectorially as follows;
v = 6·i + 8·j
|V| = [tex]\sqrt{Vx^{2} + Vy^{2} }[/tex]
|V| = [tex]\sqrt{6^{2} + 8^{2} }[/tex]
= [tex]\sqrt{64 + 36}[/tex]
= √100
|V| = 10
Therefore if a body is moving in the horizontal axis with a velocity Vx= 6m/s and in the vertical axis Vy=8m/s, the magnitude of the velocity of the body V is 10

6) A ferris wheel can accommodate 45 people in 30 minutes. How many peoplecould ride the ferris wheel in 3 hours? What was that rate per hour?
The ferris well can accomodate 45 people in 30 minutes.
You need to calculate how many people you can accomodate in 3 hours.
To do so the first step is to express the 3 hours in minutes:
You know that 1 hour has 60 minutes, multiply 60 by 3 to determine how many minutes there are in 3 hours:
[tex]60\cdot3=180[/tex]3 hours equal to 180 minutes
Now you can use cross multiplication to determine the number of people that can ride the ferris well in three hours.
30 min_____45 people
180min_____x people
[tex]\begin{gathered} \frac{45}{30}=\frac{x}{180} \\ x=(\frac{45}{30})180 \\ x=270 \end{gathered}[/tex]The ferris well can accomodate 270 persons in 3 hours.

( 31.2u + 0.2 v ) is expression represents the perimeter of rectangle .
What is rectangle short answer?
A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. Because of this, it is also known as an equiangular quadrilateral. Because the opposite sides of a rectangle are equal and parallel, it can also be referred to as a parallelogram.length of rectangle = ( 7.2u + 9.9v)
width of rectangle = ( 8.4u - 9.8v)
perimeter of rectangle = 2( l + b )
= 2 ( 7.2u + 9.9v + 8.4u - 9.8v )
= 2 ( 7.2u + 8.4u + 9.9v - 9.8v )

- If T is the midpoint of SU, what are ST, TU, and SU?
9x
6x=30
The midpoint of a segment is the point that divides the segment in half. Knowing this, we will receive:
ST = 90
TU = 90
SU = 180
Solution:A line segment's midpoint is a point that is halfway between two points. The midpoint is the same distance between the two ends.So here, if T is the midpoint of SU, we will have:
ST = TU
And we have terms for these measures:
ST = 9x
TU = 6x + 30
we can write it as:
9 x = 36 x + 30
Now solve this for x.
9x - 6 x = 30
3 x = 30
x = 30 / 3 = 10
x = 10
Now that we know what the value of x is, we can use it to solve the equations to determine the length of each segment:
ST = 9 x
= 9 × 10 = 90
TU = 6 x + 30
= 6 × 10 + 30 = 90
SU = ST + TU
= 90 + 90 = 180
ST = 90
TU = 90
SU = 180

A right triangle is made up of two legs and one hypotenuse. The two legs meet at a 90° angle, and the hypotenuse is the right triangle's longest side and the side opposite the right angle.
What is Right triangle?A right triangle, also known as a right-angled triangle, or more formally an orthogonal triangle, formerly known as a rectangle triangle, is a triangle with one right angle or two perpendicular sides. Trigonometry is founded on the relationship between the sides and other angles of a right triangle. A right-angled triangle exists a triangle in which one of the angles stands 90 degrees. The sum of the other two angles is 90 degrees. The sides that include the right angle are perpendicular and form the triangle's base. The third side is known as the hypotenuse, and it is the longest of the three sides.Therefore,
M = 30°, O = 60°, Q = 90°. Because this is a right angle triangle with angle 90°

If the divisor is a decimal then you must multiply by a power of 10 to make it a whole number. Why is it important to multiply the dividend and the divisor by the same power of 10? NEED HELP ASAP WILL GIVE BRAINLIST ALSO NO SAMPLE RESPONSE
In this example, the number being divided (15) is known as the dividend, and the number being divided by (3 in this instance) is known as the divisor. The quotient is the outcome of the division. Observe how 15 x 3 = 5 is a correct equation even if you change the quotient and divisor.
Explain about the divisor and dividend?The dividend appears to the right, or underneath, the division bracket, while the divisor is the number that appears to the left, or outside, of the division bracket.
An integer that divides another integer to obtain a result is called a divisor. The result of this division, or quotient, is the dividend, which is the original number that was divided. Quotient = Dividend Divisor.
To keep the divisor and dividend in the same proportion to one another, you multiply them by the same power.
This is true for division that is not decimal.
10 / 5 = 2.
Multiplying both sides by ten results in 100/50, which is still two.
If you merely divided by 10, you would get 100/5, which is equal to 20, or 10/50, which is equal to 1/5. Both of these throw off the ratio.

What is an example of a unitary method?A single or distinct unit is referred to by the word unitary. Therefore, the goal of this strategy is to establish values in reference to a single unit. The unitary technique, for instance, can be used to calculate how many kilometers a car will go on one litre of gas if it travels 44 km on two litres of fuel. The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.
Given:
Bags of 2 cat food cost $9.50

the temperature at jebel jais on a particular winter morning is "-3c" at 5 am . if the temperature drops 2 degree at 6am and rises 7 degree ar 8am and again drops 1 at 9am . what is the temperature at 6am and 9am
The temperature at jebel jais at 6 a.m. will be -5 °C and the temperature at 9 a.m will be 1 °C.
What is temperature?A temperature is a unit of hotness or coldness that can be described in terms of a variety of arbitrary scales. It also indicates the direction in which heat energy will naturally flow, i.e., from a hotter body to a colder body (one at a lower temperature). Temperature is not the same as the energy of a thermodynamic system; for instance, an iceberg has a considerably higher temperature than a burning match, but it has a far larger total heat energy than a match.
According to the question,
The temperature at 5 a.m = -3 °C
The temperature at drops by 2 °C at 6 a.m = -3°C - 2 °C
The total temperature at 6 a.m = -5 °C
The temperature rises by 7 °C at 8 a.m.
The net temperature by 8 a.m = -5 °C + 7 °C = 2 °C
The temperature drops by 1 °C at 9 a.m.
The net temperature at 9 a.m = 2 °C - 1 °C = 1 °C
Hence, the temperature at 6 a.m is -5 °C and the temperature at 9 a.m is 1 °C.

we have proved
∠DEC = ∠AEB
Proof:Given,
The straight line has a 180-degree angle.
The two lines AC and BD intersect at E.
consider AEB : BEC = 9: 11.
If BEC is x, then AEB is 9x / 11 and AEC + BEC

9x + 11x = 11 * 180
20x = 11 * 180 x = 99
BEC is 99 degrees and AEB is 81 degrees.
Because angle AED is vertically opposite angle BEC, angle AED = 99 degrees.
