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

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

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

Fraction of body weight that's water = 7/10
Weight 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.

$\sf \: 140 \times \frac{7}{10} \\ \sf = 14 \bcancel{0} \times \frac{7}{1 \bcancel{0}} \\ \sf = 14 \times 7 \\ = \boxed{\boxed{\bf \: 98 \: pounds}}$

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

Answer:

Step-by-step explanation:

x + 14 $\frac{13}{25}$ = -0.87

x + $\frac{363}{25}$ = - $\frac{87}{100}$

x + $\frac{1452}{100}$ = - $\frac{87}{100}$

x = - $\frac{87}{100}$ - $\frac{1452}{100}$

x = - $\frac{1539}{100}$

x -8 $\frac{5}{6}$ = 1.5

x - $\frac{53}{6}$ = $\frac{9}{6}$

x = $\frac{9}{6}$ + $\frac{53}{6}$

x = $\frac{62}{6}$

x = $\frac{31}{3}$

x - $\frac{7}{12}$ = - 7 $\frac{7}{16}$

x - $\frac{28}{48}$ = - $\frac{119}{16}$

x = - $\frac{357}{48}$ + $\frac{28}{48}$

x = - $\frac{329}{48}$

$\frac{8}{9}$ - x = 6 $\frac{1}{15}$

$\frac{8}{9}$ = $\frac{91}{15}$ + x

$\frac{40}{45}$ - $\frac{273}{45}$ = x

- $\frac{233}{45}$ = x

x = - $\frac{233}{45}$

-33.754 - x = 28.05

-33.754 - 28.05 = x

- 61.804 = x

x = - 61.804

a lab technician mixed a 690 ml solution of water and alcohol, if 3% of the solution is alcohol, how many milliliters of alcohol

neonofarm [45]

To get the milliliters of alcohol used, we must multiply 690 by 0.03. If we do this, we will get 20.70, which means that 20.70 milliliters of alcohol were used. On the other hand, we can get the milliliters of water used through two ways: the first one is by simply subtracting 20.70 from 690, which will give us the answer 669.30. Another would be by multiplying 690 by 0.97, which will also yield the answer 669.30. The number of milliliters of water used was 669.30.
