A study showed that 7/10 of the human body weight is water. If a person weighs 140 pounds, how many pounds is water?

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

Okay, so first let's note down the points we've in the question.

Fraction of body weight that's water = 7/10Weight of the person = 140 pounds.Number of pounds that's water = ?

To find how many pounds of the person who weighs 140 pounds is water, we need to multiply 140 into 7/10.

⇨ Let's solve it now.

[tex] \sf \: 140 \times \frac{7}{10} \\ \sf = 14 \bcancel{0} \times \frac{7}{1 \bcancel{0}} \\ \sf = 14 \times 7 \\ = \boxed{\boxed{\bf \: 98 \: pounds}}[/tex]

A person who weighs 140 pounds will be approximately 98 pounds water.

Does America live up to its core values?

Answers

The core values of America are summed up by Freedom, Justice, and Equality. Although there are many people who say that America has no problem with this, one may argue that it does not. Since the beginning of the start of America becoming a country, slavery and assimilation has been a major issue that has caused setbacks for many minorities and racial groups. Slavery and discrimination both play a part in why Natives and African Americans have high poverty rates, the loss of culture, ect. When it comes to the policing of African Americans, have been disproportionately incarcerated vs White Americans. This includes also being stopped, said they look suspicious, and the way things are handled.

10. The Earth’s escape speed (the speed you need to get away forever) is about 25,000 miles per hour. Escape speed depends on the gravity of the object trying to hold the spacecraft from escaping. Based on your understanding of gravity, how will the escape speed from the Moon compare to the escape speed from Earth?
a. The Moon’s escape speed will be greater than Earth’s
b. The Moon’s escape speed will be smaller than Earth’s
c. The Moon’s escape speed will be exactly the same as Earth’s
d. The Moon’s escape speed will change depending on whether it’s a crescent Moon or a full Moon
e. The Moon’s escape speed will be balanced by the Earth being so close and it will be zero

Answers

“Escape speed depends on the gravity of the object trying to hold the spacecraft from escaping”
Gravity on the moon is less than on Earth, because the mass of the moon is small than then mass of Earth.

Since gravity on the moon is less and escape speed depends on that gravity,
=> the moon’s escape speed will be smaller than Earth’s.

Her jump rope Ella can make 17 jumps in 15 second.at this rate how make jumps can she make in20 minute?

Answers

Answer:

1360

Step-by-step explanation:

there are 1200 seconds in 20 minutes. if Ella can do 17 jumps in 15 seconds, you would divide 1200 by 15 (which equals 80) because that would be the number of 15 seconds in 20 minutes. then you would divide 80 by 17, which gives you your final answer of 1360 jumps in 20 minutes.

According to data, as education level increases the unemployment rate decreases. This is an example of
what type of correlation?

Answers

I don’t think I just want points

As education level increases the unemployment rate decreases this is a negative linear type correlation.

What are the main types of correlation ?

There are three main types of correlations they are positive linear correlation where both the variables related to each other increase or decrease simultaneously.

In negative linear correlation between two variables if one variable is increasing the other starts to decrease and vice versa and the third type of correlation is where there is no correlation increase and decrease happen in random way that is quite difficult to form in terms of numerical form or graphing them.

According to the given statement as education level increases the unemployment rate decreases.

This is an example of negative linear correlation as one variable increases the other related to it decreases.

Increase in education level decreases unemployment as with higher education people learn new skills,they become more aware of their surroundings and most importantly education teaches us to think logically these are the things that a co-operate world wants.

What is -2/3 - (-1/2)

Answers

Answer: -1/6

Step-by-step explanation: Start by changing the minus a negative

to plus a positive, so we have -2/3 + 1/2.

Since our denominators of 3 and 2 have no factors in common,

our least common denominator is 3 · 2 or 6.

In order to get a denominator of 6 in each fraction,

we multiply top  and bottom of the first fraction by 2

and top and bottom of the second fraction by 3.

That gives us -4/6 + 3/6 which simplifies to -1/6.

Katarina asks Dacia how she can you derive the formula r= x2+y2. Which of Dacia's replies are correct?

Answers

Options A and B are correct. If Katarina asks Dacia how she can derive the formula r= x²+y², then the following statements should be Dacia's reply.

Because r is the hypotenuse of a right triangle, with legs x and y, you can use the Pythagorean theorem to determine 'r

r is a straight line distance from the point and can be projected onto x and y axes where x = rcosθ, y = rsinθ. Writing sinθ = y/r, Cosθ = x/r and using the identity sin²θ+cos²θ = 1

Given the equation by Katarina expressed as:

r = √x²+y²

One of the ways Katarina can derive the equation is to use the Pythagoras theorem which states that the sum of the square of the hypotenuse is equal to the sum of the other two sides. Let:

r be the length of the hypotenuse

x and y be the other two sides

According to the theorem:

r² = x² + y²

Take the square root of both sides

√r² = √x² + y²

r = √x² + y²

Also, Katarina can use the trigonometry identity. According to a right triangle where:

sinθ = y/r

Cosθ = x/r

According to trigonometry identity, sin²θ+cos²θ = 1

(y/r)² + (x/r)² = 1

y²/r² + x²/r² = 1

(y²+x²)/r²  = 1

y²+x²  = r²

Swap

r²=y²+x²

This shows that the first two options are correct.

Because r is the hypotenuse of a right triangle, with legs x and y, you can use the Pythagorean theorem to determine 'r

r is a straight line distance from the point and can be projected onto x and y axes where x = rcosθ, y = rsinθ. Writing sinθ = y/r, Cosθ = x/r and using the identity sin²θ+cos²θ = 1
