Answer:

308.65 Pounds

Step-by-step explanation:

Since one kilogram is 2.20462 pounds you can multiply 140 by 2.20462 to get 308.6468 and rounded to the nearest hundredth it would be 308.65.

The weight of a 140 kilogram person in pounds is approximately 308.64 pounds, when rounded to the nearest hundredth.

To find the weight of a 140-kilogram person in pounds, we first need to understand that weight is a measure of the force of gravity on an object and can be calculated by multiplying the mass of the object by the acceleration due to gravity.

However, here, we are converting kilograms to pounds, which is a conversion of mass units, not weight. The conversion factor from kilograms to pounds is approximately 2.2046.

Therefore, to convert 140 kilograms into pounds, we multiply 140 by 2.2046:

140 kg * 2.2046 = 308.644 pounds.

And rounded to the nearest hundredth, we get 308.64 pounds.

Step-by-step explanation:

The saving balance is found by the equation;

Answer:

300 ft-lbs

Step-by-step explanation:

For work like this,

Just multiply 100 times 3.

You always just multiply the two numbers

Example:

Calculate the work done.

A crane lifts 5,000 newtons to the top of a roof which is 6 meters high.

3,000 ft-lbs

30,000 Nm

5,000 Nm

300 Nm

5,000 x 6 = 30,00

it can also be done like this

5 x 6 = 30

+ 00 = 30,00

The work done is 300 ft-lbs, the correct option is D.

The multiplication of the magnitude of displacement d and the component of the force that is in the direction of displacement is called work done.

Work done is positive when the energy leaves the system. Here, the system is making an effort on the surroundings.

A tractor pulls a heavy log with a force of 100 pounds.

The log moves 3 feet.

The work done is given by;

[tex]\rm Work \ done=Force \times Displacement\\\\Work \ done= 100 \times 3 \\\\Work \ done=300\ ft-lbs[/tex]

Hence, the work done is 300 ft-lbs, the correct option is D.

Step-by-step explanation:

Cause 8+1 =9

Answer:

8

Explanation:

to get the answer we have to use the opposite of addition which is subtraction. we flip around the equation so now it would be 9 - 1 = ?

9 minus 1 is 8.

that is how you get the answer.

The closing bracket ']' in the inequality solution set (–∞, 6.5] indicates that 6.5 is included, making it a solution to the inequality.

The solution to an inequality is (–∞, 6.5]. To determine if 6.5 is a solution to the inequality, we look at the notation used. The parenthesis '(' indicates that the number at this end of the interval is not included in the solution set, while the bracket ']' indicates that the number at this end is included. Since 6.5 is associated with a closing bracket, it means that 6.5 is indeed a solution to the inequality. Therefore, any number less than or equal to 6.5 is a solution to this particular inequality.

The correct explanation among the given options is the following:

"The solution includes numbers from negative infinity to 6.5. Because a bracket is used, the solution includes 6.5."

In interval notation, brackets ([ and ]) indicate that the endpoint is included in the solution, while parentheses (( and )) indicate that the endpoint is not included.

Here, with (-∞, 6.5], the closing bracket means 6.5 is included in the solution to the inequality.

Thus, 6.5 is a valid solution to the inequality.

The complete question is : The solution to an inequality is (-, 6.5]. Is 6.5 a solution to the inequality? Explain your answer

The solution includes numbers from negative infinity to 6.5. Because a bracket is used, the salution does not

include 6.5. The solution includes numbers from 6.5 to infinity. Because a parenthesis is used, the solution does not include 6.5.

The solution is the point(, 6.5). Because a bracket is used, 6.5 is a solution to the inequality.

The solution includes numbers from negative infinity to 6.5. Because a bracket is used, the solution includes 6.5.

To solve this you must use a proportion like so...

[tex]\frac{part}{whole} = \frac{part}{whole}[/tex]

60 is a percent and percents are always taken out of the 100. This means that one proportion will have 60 as the part and 100 as the whole

We want to know out of what number is 12 60%. This means 12 is the part and the unknown (let's make this x) is the whole

[tex]\frac{12}{x} =\frac{60}{100}[/tex]

Now you must cross multiply

12*100 = 60*x

1200 = 60x

To isolate x divide 60 to both sides

1200/60 = 60x/60

20 = x

This means that 60% of 20 is 12

It turns out that all three altitudes always intersect at the same point - the so-called orthocenter of the triangle. The orthocenter is not always inside the triangle. If the triangle is obtuse, it will be outside. To make this happen the altitude lines have to be extended so they cross.

Answer:

A.

Step-by-step explanation:

To find a significant figure you just count how many numbers are before and after the decimal place but if the first number is zero then it does not count.

Final answer:

The values with 3 significant figures are A. 10.1 and D. 129, as non-zero numbers are always significant, and there are no leading, captive, or trailing zeros to consider in these cases.

Explanation:

The values that have 3 significant figures are:

A. 10.1

D. 129

In A, all the digits are significant because they are all non-zero numbers. In D, similarly, all digits are significant since non-zero numbers are always counted as significant figures.

For the options not chosen:

B. 100.05 has 5 significant figures because zeros between non-zero numbers are significant and so are the ending non-zero numbers.

C. 120 may be seen as having 2 or 3 significant figures depending on whether the zero is considered significant; additional context such as writing the number in scientific notation or a decimal point (120.) is needed to clarify its significance.

Answer:

(3x - 4)(8x - 3)

Step-by-step explanation:

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 24 × 12 and sum = - 41

The required factors are - 32 and - 9

Use these factors to split the x- term

24x² - 32x - 9x + 12 ( factor the first/second and third/fourth terms )

= 8x(3x - 4) - 3(3x - 4) ← factor out (3x - 4) from each term

= (3x - 4)(8x - 3) ← in factored form

SA = 55 + 66 + 60

SA = 181

The answer is C) 181 cm²

Correct Option is C , 181 square cms.

l = 11cm

b = 10cm

Surface Area of Cuboid:

A cuboid has 6  rectangular faces, the surface area of the whole cuboid is the sum of 6 rectangular surface areas of cuboid.

surface area = l x b + b x h + h x l + l x b + b x h + h x l

Surface area of cuboid = 2 x ((l x b) + (b x h) + (h x l))

When the length of each side is cut in half so, l, b and h decreases by 2.

l =  [tex]\frac{l}{2}[/tex] = [tex]\frac{11}{2}[/tex] = 5.5cm

b = [tex]\frac{b}{2}[/tex] = [tex]\frac{10}{2}[/tex] = 5cm

h = [tex]\frac{h}{2}[/tex] = [tex]\frac{12}{2}[/tex] = 6cm

Surface Area of the cuboid = 2 x ((l x b) + (b x h) + (h x l))

=>  2 x ((5.5 x 5) + (5 x 6) + (6 x 5.5))

=> 2 x (27.5 + 30 + 33)

Answer:

The distance between the police station and the fire station is 4 miles

Step-by-step explanation:

* Lets study the situation in the problem to solve it

- In the city there are three places, library , police station and fire station

- The distance between the library and the police station is 3 miles

  less than twice the distance between the police station and the

  fire station

- The distance between the library and the police station is 5 miles

* Lets change all of these situation to equations

# Let the distance between the library and the police station is x

# Let the distance between the police station and the fire station is y

∵ The distance between the library and the police station (x) is 3 miles

  less than twice the distance between the police station and the

  fire station (y)

∴ x = 2y - 3

∵ The distance between the library and the police station is (x) 5 miles

∴ x = 5

- Substitute the value of x in the equation above

∵ x = 2y - 3

∵ x = 5

∴ 5 = 2y - 3 ⇒ add 3 to both sides

∴ 8 = 2y ⇒ divide both sides by 2

∴ 4 = y

∵ y is the distance between the police station and the fire station

∴ The police station is 4 miles apart from the fire station

* The distance between the police station and the fire station is 4 miles
