From the given information, by using mass conversion, 156 lbs is equal to approximately 70.76 kg.
Mass conversion is the process of converting a given mass from one unit of measurement to another. It involves using a conversion factor to change the numerical value of the mass while keeping the physical quantity constant.
For example, converting a mass from pounds to kilograms involves using a conversion factor of 0.45359237 kg/lb.
To convert pounds to kilograms, you can use the following conversion formula:
1 lb = 0.45359237 kg
So, to convert 156 lbs to kg, you can multiply 156 by 0.45359237:
156 lbs × 0.45359237 kg/lb = 70.76 kg (rounded to two decimal places)

Answer:
y = - 1 , y = 17
Step-by-step explanation:
y² - 16y + 64 = 81 ← y² - 16y + 64 is a perfect square
)y - 8)² = 81 ( take the square root of both sides )
y - 8 = ± [tex]\sqrt{81}[/tex] = ± 9 ( add 8 to both sides )
y = 8 ± 9
then
y = 8 - 9 = - 1
x = 8 + 9 = 17

In ΔNOP, p = 490 inches, m∠N=57° and m∠O=55°. Find the length of n, to the nearest inch.
The value of n is 443 inches when using the triangle rule and law of sine.
What is meant by Sine Rule?An oblique triangle's sides and angles are related according to the rule of sines (non-right triangle). The laws of sines and cosines are crucial trigonometrical formulas for "solving a triangle." The sine rule states that there is an equal relationship between a triangle's side lengths and the sine of each of its opposite angles.Triangles' side length to opposite angle ratios are governed by the law of sines. For all three sides and perpendicular angles, this ratio remains constant. So long as the necessary information is known, we may use the sine rule to determine the missing side or angle of any triangle.The formula is given as
a / sin A = b / sin B = c / sin C
In this triangle NOP, we can find the value of angle P
∠N + ∠O + ∠P = 180
57 + 55 + ∠P = 180 : Sum of angles in a triangle is equal 180 degrees
∠P = 180 - 112
∠P = 68
Using law of sine
p/sin P = n/sin N
490/sin68 = n / sin57
n = [(490 × sin 57) / sin 68]
n = 443 inches

Similar triangles are two triangles that have the same shape but may be scaled to different sizes. In other words, similar triangles have the same angles, but their sides may be proportional.
In the problem, the proportion of the sides are equal and this will maintain the size of the angle
let the size of the angle be x
Sin x = opposite / hypotenuse
Sin x = 2.63 / 5.26 = 3.945 / 7.89 = 5.26 / 10.52 = 0.5

treena won a 7 day scholarship with $1000 to the pro shet basketball camp. rand trip travel exanse to the camp are $335 bh air or $125 by train. at the camp she much choose beteeen a week of individual instruction at $60 per dah or a week of group instruction at $40 per day. treenas food if she does not plan to spef money ofter then the scholarship ehat atr all choices of travel and induction plans that she could afford to make?
Answer:
To solve this problem, we need to calculate the cost of each travel and instruction option and then determine which options Treena can afford with her $1000 scholarship.
Option 1: Air travel and individual instruction
Travel cost: $335
Instruction cost: 7 x $60 = $420
Total cost: $335 + $420 = $755
Option 2: Air travel and group instruction
Travel cost: $335
Instruction cost: 7 x $40 = $280
Total cost: $335 + $280 = $615
Option 3: Train travel and individual instruction
Travel cost: $125
Instruction cost: 7 x $60 = $420
Total cost: $125 + $420 = $545
Option 4: Train travel and group instruction
Travel cost: $125
Instruction cost: 7 x $40 = $280
Total cost: $125 + $280 = $405
Now we need to determine which options Treena can afford with her $1000 scholarship. We'll start with the most expensive option and work our way down.
Option 1: $755
This option is too expensive for Treena's $1000 scholarship.
Option 2: $615
This option is also too expensive for Treena's $1000 scholarship.
Option 3: $545
This option is within Treena's budget, but she won't have any money left for food.
Option 4: $405
This option is also within Treena's budget, and she'll have $595 left for food.
Therefore, Treena's choices of travel and instruction plans that she could afford to make are:
- Train travel and group instruction with $595 left for food
- Train travel and individual instruction with no money left for food

the mean and the median of the given data set are 16.75 and 9.5 respectively.
What is Mean?The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
Given, A data set 8, 9, 10, 40
From the general formula of mean:
mean = (sum of observations) ÷ (total number of observations).
mean = (8 + 9 + 10+ 40)/4
mean = 67/4
mean = 16.75
Since the median is:
The median is the value that's exactly in the middle of a dataset when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values.
Thus,
the median of the given data set = (9 +10)/2
the median of the given data set = 9.5
Therefore, the mean and the median of the given data set are 16.75 and 9.5 respectively.

solve for v. 4v-18=6(v-6)
Answer:
v = 9
Step-by-step explanation:
4v - 18 = 6(v - 6)
1.) Distribute 6 into the parenthesis
4v-18 = 6v - 36
2.) Move 6v to the other side by subtracting from both sides
4v - 6v -18 = -36
3.) Move 18 to the other side by adding 18 on both sides
4v - 6v = 18 + -36
4.) Combine like terms
-2v = -18
5.) Divide -2 on both sides to get v by itself
v = 9
Answer:
the answer is 9
Step-by-step explanation:
4v-18=6(v-6)
4v-18=6v-36
4v-6v= -36+18
-2v= -18
divide both sides by -2

how to find the missing dimension of. a cone when the when the highest s 4.2 and the volume is 3.6 cubed
To find the missing dimension of a cone when the height is 4.2 and the volume is 3.6 cubed is to equate the general formula with the given information.
What is a cone?A cone is a three-dimensional geometric shape with a smooth and curving surface and a flat base, with an increase in the height radius of a cone decreasing to a certain point.
The volume of a cone is (1/3)πr²h.
The total surface area of a cone is πr(r + l).
The curved surface area is πrl.
To obtain the missing dimension of a cone we must equate the general formula for the volume of a cone to the given information.
Therefore, (1/3)πr²×4.2 = 3.6
(1/3)πr² = 0.86.
r² = 0.86/1.05.
r² = 0.82.

The amount in the account after 15 years after round of to the nearest hundredth is $6,671.67, the correct option is B.
How to find the compound interest?If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:

What is the surface area of a rectangular prism if the digits are 10ft, 1ft, and 5ft
The surface area of the rectangular prism is 130ft^2.
Determine surface areaThe surface area of a rectangular prism can be calculated by finding the area of each of the six faces and then adding them together.
The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
In this case, the length is 10ft, the width is 1ft, and the height is 5ft. Plugging these values into the formula, we get:
Surface area = 2(10ft)(1ft) + 2(10ft)(5ft) + 2(1ft)(5ft)
Surface area = 20ft^2 + 100ft^2 + 10ft^2
Surface area = 130ft^2

Visualizing Kruskal's algorithm involves representing the graph, its edges, and the minimum spanning tree in a visual format.
To visualize a Kruskal algorithm, you need to follow the steps below:
1. Sort all the edges in ascending order of weight.
2. Create a new graph G' with the same vertices as the original graph G, but no edges.
3. Start with the smallest edge and add it to G' if it doesn't create a cycle. Repeat this step until you have added all the edges or you have a minimum spanning tree.
4. If you have a minimum spanning tree, you can visualize it by drawing the graph with the edges included in G'.
Here is an example:
