The value of the speed(v) is 5.14 km/hr
What is speed?Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector. Speed is measured in m/s and km/hr
speed = distance / time
distance = 3km
converting the time in seconds to hour,
time = 35 mins = 35/60 = 7/12 hr
speed = 3 ÷ 7/12
= 3× 12/7
= 36/7
= 5.14 km/hr
therefore the speed of the boy is 5.14 km/hr

The letters of the alphabet are written on
cards and placed in a brown paper bag. What
is the probability of drawing a vowel,
replacing it, and then drawing a Z?
The probability of drawing a vowel, replacing it, and then drawing a Z is 5/676.
The alphabet consists of 26 letters, and 5 of them are vowels (A, E, I, O, U). Hence, 5/26 of the time, a vowel will be drawn in the initial draw.
The likelihood of drawing a Z on the second draw is also 1/26, due to the fact that the card is changed after the first draw.
We can multiply the probabilities to determine the likelihood that both of these occurrences will occur:
P(Draw a Z after a vowel is drawn) = P(Draw a vowel) P(Draw a Z after the vowel is replaced) = (5/26) (1/26) = 5/676
As a result, the likelihood of drawing a Z after substituting a vowel is 5/676.

On the first day of school, Ms. Dubacek gave her third-grade students
6 new spelling words to learn. On each day of school after that, she gave the students 3 new spelling words. How many new spelling words had she given the students by the end of the 21st day of school?
Answer: 126 Spelling Words
Step-by-step explanation: I got that because you had to multiply 6 by 21 and you get 126.Answer:
Step-by-step explanation:
On the first day, Ms. Dubacek gave 6 new spelling words.
On each subsequent day, she gave an additional 3 new spelling words.
Therefore, on the second day of school, she gave a total of 6 + 3 = 9 new spelling words.
On the third day of school, she gave a total of 6 + 3 + 3 = 12 new spelling words.
We can see a pattern emerging here: on each day, she gives 6 more words than the previous day.
So on the 21st day of school, she will have given a total of:
6 + (9 + 12 + 15 + ... + 60)
To find the sum of this arithmetic series, we can use the formula:
S = n/2 * (a + l)
where:
S = the sum of the series
n = the number of terms in the series
a = the first term in the series
l = the last term in the series
In this case, we have:
n = 19 (since we're counting from the second day of school to the 21st day)
a = 9 (since that was the total number of spelling words given on the second day)
l = 60 (since that will be the total number of spelling words given on the 21st day)
So, plugging in these values, we get:
S = 19/2 * (9 + 60) = 19/2 * 69 = 655.5
Therefore, by the end of the 21st day of school, Ms. Dubacek will have given her students a total of 6 + 655.5 = 661.5 new spelling words (rounded to the nearest whole number, this is 662).

What is triangle ?
A triangle is a polygon with three sides and three angles. It is a two-dimensional figure that is formed by connecting three non-collinear points. The sum of the angles in a triangle is always 180 degrees, and the side opposite to the largest angle is the longest side of the triangle, while the side opposite to the smallest angle is the shortest side.
According to given information :In this problem, we are given a triangle ABC with vertices at A(3, 2), B(2, −1), C(−2, 1), and we are asked to dilate it using a scale factor of 1.5 to create triangle A′B′C′.
Dilation is a transformation that changes the size of a figure but not its shape. To dilate a figure, we multiply the coordinates of each point by a scale factor. In this case, we are given a scale factor of 1.5, so we will multiply each coordinate of triangle ABC by 1.5 to get the coordinates of triangle A′B′C′.
To find the vertex of point A′, we need to apply the dilation to the coordinates of point A(3, 2). Multiplying the x-coordinate by 1.5, we get 1.5 × 3 = 4.5. Multiplying the y-coordinate by 1.5, we get 1.5 × 2 = 3.
Therefore, the coordinates of point A′ are (4.5, 3), the answer is A′(4.5, 3).

The Silver Spur is a popular local hiking trail. The start of the trail is 179ft above sea level. The table shows the amount of elevation gain between the previous point of interest on the trail and the current one. (The elevation gain shown for the Old Cabin is the elevation gained between the start of the trail and the Old Cabin.) Point of Interest Elevation gain (in ft) Old Cabin −32.78 Ruby Falls 8634 Thunder Gorge −14725 High Point Vista 346.47 What is a hiker’s elevation above sea level (in feet) upon reaching High Point Vista?
Answer:
Step-by-step explanation:
To find the hiker's elevation above sea level upon reaching High Point Vista, we need to add up the elevation gain from the start of the trail to High Point Vista. We can use the table to do this:
Elevation gain from start to Old Cabin: -32.78 ft (negative because the hiker loses elevation)
Elevation gain from Old Cabin to Ruby Falls: 8634 ft
Elevation gain from Ruby Falls to Thunder Gorge: -14725 ft (negative because the hiker loses elevation)
Elevation gain from Thunder Gorge to High Point Vista: 346.47 ft
To find the hiker's elevation above sea level at High Point Vista, we add up these elevation gains:
179 ft (start) - 32.78 ft + 8634 ft - 14725 ft + 346.47 ft = -5668.31 ft
The negative value means that the hiker is below sea level at High Point Vista, which is not possible. Therefore, there must be an error in the elevation gain listed for one of the points of interest. It's possible that the elevation gain for Ruby Falls is incorrect, as it seems unlikely that the hiker would gain more than 8000 ft in elevation between Old Cabin and Ruby Falls. Without more information, it's difficult to say for sure where the error lies.

What is a rectangle pyramid ?
A rectangular pyramid is a pyramid, which has a rectangular-shaped base. If we look at the bottom view of this pyramid, it looks like a rectangle. Hence, the base has two parallel sides equal.
A pyramid crowns at a point on top of the base, which is known as the apex. A rectangular pyramid can be a right pyramid or oblique pyramid. If it is a right rectangular pyramid, then the apex lies right over the center of the base and if it is an oblique rectangular pyramid, the apex is not directly over the center of the base, but at some angle from the center.
Apart from the rectangular pyramid, there are other types of pyramids based on the shape of their bases, such as:

If 10% of a number is 12 and 35%% of the same number is 42, find 25%% of that number.
42 is not the answer
Answer:25% of the number is 30
Step-by-step explanation:
Let's call the number we're looking for "x". We can use the information given in the problem to set up two equations:
10% of x is 12:
0.1x = 12
35% of x is 42:
0.35x = 42
Now we can solve for x:
0.1x = 12
x = 120
0.35x = 42
x = 120
We get the same value for x from both equations, which confirms that our solution is correct. Now that we know x = 120, we can find 25% of that number:
25% of 120 = 0.25 x 120 = 30
Therefore, 25% of the number is 30.

What is a number series?
A series of numbers is called a number series. We must identify the rules that lead to the formation of a number series in order to answer the questions about number series. The questions that might arise from these topics are as varied as these series themselves.
One possible pattern in this sequence is that each number is the reverse of the sum of the digits of the previous number, followed by the next odd number. Applying this pattern to the given sequence, we have:
The reverse of 63 is 36. The sum of the digits of 63 is 6 + 3 = 9. Therefore, the next number is 36 + 9 = 45, followed by the next odd number, which is 47. So the next number is 47.
The reverse of 00 is 00. The sum of the digits of 00 is 0 + 0 = 0. Therefore, the next number is 00 + 0 = 0, followed by the next odd number, which is 1. So the next number is 1.
The reverse of 22 is 22. The sum of the digits of 22 is 2 + 2 = 4. Therefore, the next number is 22 + 4 = 26, followed by the next odd number, which is 27. So the next number is 27.

Using the altitude or leg rule, we have:
x ≈ 42.7
y = 40
z ≈ 53.4
How to Apply the Altitude or Leg Rule?The leg rule is given as:
hypotenuse/leg = leg/part.
The altitude rule is:
left/altitude = altitude/right
To find the value of x, apply the altitude rule:
left = x
right = 24
altitude = 32
Substitute:
x/32 = 32/24
Cross multiply:
24x = 32²
24x = 1,024
x ≈ 42.7
To find y, apply the leg rule:
leg = y
part = 24
hypotenuse = x + 24 = 42.7 + 24 = 66.7
Substitute:
66.7/y = y/24
y² = 1,600.8
y = √1x00.8
y = 40
To find z, apply the leg rule:
leg = z
part = x = 42.7
Hypotenuse = 66.7
Substitute:
66.7/z = z/42.7
z² = 2,848.09
