The average of two numbers, A and B, is calculated by adding them together and then dividing by two. In this case, A = 21, B = 20, X = 19, and Y = 20. When we calculate (A + B) / 2, we get 20.00.

1. Add A and B together: 21 + 20 = 41

2. Divide the sum by 2: 41 ÷ 2 = 20.50

3. Round the answer to two decimal places: 20.50 → 20.00

The average of two numbers, A and B, is calculated by adding them together and then dividing by two. This formula is expressed as (A + B) / 2. In this problem, we were given the values A = 21, B = 20, X = 19, and Y = 20. To solve for the average, we first need to add A and B together and get 41. Then we divide this sum by two and get 20.50.

Answer:

22.386

Step-by-step explanation:

The tall of the building is 175m and the baseball strikes the ground in 4.53 seconds, 195 ft/s.

Assume that the acceleration due to gravity is 10m/s2.  

The equation for the ball’s velocity in the downward direction is

v(t) = at + v₀.

Here

v₀=10m/s a=10m/s² v(t)=60m/s

Solving this for  t we get the:  

[tex]t =\frac{60m/s-10m/s}{10m/s^2}\\ \\t=\frac{50m/s}{10m/s^2}\\[/tex]

t=5s

The total distance traveled will be  

[tex]x(t)=\frac{1}{2} at^2+v_{0} +x_{0}[/tex]

Here x₀ = 0 and we get:

[tex]x(t)=\frac{1}{2} (10m/s^2)(5s)^2+(10m/s)(5s)[/tex]

x=125m+50m

x=175m

The given values are:

u = 50 ft/s

h = 555 ft

g = 32 ft/s²

Let the time taken by the ball to reach the ground be t and the velocity of the ball as it hits the ground be v.

Use the third equation of motion

v²=u²+2as

v²=50²+2*32*555

v = 195 ft /s

Thus, the ball strikes the ground with a velocity of 195 ft/s.

Use the first equation of motion

v = u + at

195 = 50 + 32 t

32 t = 145

t = 4.53 second

Thus, the ball reaches the ground in 4.53 seconds.

To determine the cost of 6 pencils at 60 cents a dozen, we need to convert the price per dozen to the price per pencil. We know that a dozen is equal to 12, so we can use the following formula:

Price per pencil = (Price per dozen) / (Number of items per dozen)

So, in this case:

Price per pencil = (60 cents) / (12 pencils)

To convert cents to dollars, we divide by 100.

Price per pencil = (60/100) $ = 0.6 $

To find the total cost for 6 pencils we multiply the price per pencil by the number of pencils

Cost of 6 pencils = 6 * 0.6 = 3.6 $

So the cost of 6 pencils at 60 cents a dozen is 3.6 $.

If we are taking 10% off, that is like leaving 90% (.9) on.

If we are taking 5% off, that is like leaving 95% ( .95) on.

No discount for the watch because she only bought one.

To find the x-intercept of the graph of the equation 2x - 4y = 9, we need to find the value of x when y = 0.

We can solve for x as follows:

2x - 4y = 9

2x - 4(0) = 9 (substitute y = 0)

2x = 9

x = 9/2

Therefore, the x-intercept of the graph of the equation 2x - 4y = 9 is (9/2, 0).

If the magnitude of two vectors is 10 and 6 and their dot product is 30, then the angle between the vectors is 60°.

What is a vector?

A vector in mathematics is a quantity that not only expresses magnitude but also motion or position of an object in relation to another point or object. Euclidean vector, geometric vector, and spatial vector are other names for it.

There are two ways to define a dot product: algebraically and geometrically. The sum of the products of the matching entries of the two number sequences is the definition of the dot product in algebra. Geometrically, it is the sum of the cosine of the angle formed by the two vectors and their Euclidean magnitudes.

The magnitude of the vector 1 is, |a| = 10

The magnitude of the vector 2 is, |b| = 6

The dot product of the two vectors is, a·b = 30.

The formula for dot product of vectors is -

a·b = |a| |b| cos θ

Solve the equation to get the angle -

30 = (10 × 6) cos θ

30 = 60 cos θ

cos θ = 30/60

cos θ = 1/2

θ = cos^-1 (1/2)
