The human body consists mainly of three elements. About 1/10 of a body's weight is hydrogen, 16/25 is oxygen, and 1/5 is carbon.

What is the weight of the hydrogen, oxygen, and carbon in the body of a person who weighs 134 lb?

Answer:

Hydrogen = 13.4

Oxygen = 85.76

Carbon =  26.8

Step-by-step explanation:

H= 13.4

When you multiply by 1/10 all you have to do is move the decimal point to the LEFT.

So... 134←. = 13.4

_______________________________________________________

O= 85.76

134×\frac{16}{25}=85.76

________________________________________________________

C= 26.8

134×\frac{1}{5}=26.8

Alex
Here, we need to find the area of a circle.
So, area of a circle = πr²
= 3.14 * (10, 000)²
= 3.14 * 100,000,000
= 314,000,000 ft²

In short, Your Answer would be Option A

Hope this helps!

Consider the surface defined by the equation x3 + y3 + z3 = 3xyz. Use implicit differ- ∂z entiation to find ∂x. (Note z is not a
Aloiza [94]

Answer:    

   \frac{∂z}{∂x}=\frac{(3yz-3x^{2})}{3z^{2} -3xy}

Step-by-step explanation:

Given equation is x^{3}+y^{3}+z^{3}=3xyz ………………(1)

we use derivative formula \frac{d}{dx}(x^{n})  = n x^{n-1}

\frac{d}{dx}(x^{3)}  = 3 x^{2}

\frac{d}{dx}(z^{3)}  = 3 z^{2}

And also apply 'u v' formula

\frac{d}{dx}(uv})  = u\frac{d}{dx}(v)+v\frac{d}{dx}(u)

Differentiating  equation (1) partially with respective to 'x' , we treated 'y' as constant.

(3x^{2} +0+3z^{2}\frac{∂z}{∂x}) =3y(x\frac{∂z}{∂x}+z(1))   ( here y treated as constant so the derivative of constant function is zero in addition but in multiplication the constant is keep as like 'y').

on simplification , we get

(3x^{2} +0+3z^{2}\frac{∂z}{∂x}) =(3yx\frac{∂z}{∂x}+3yz)

again simplification, we get

3z^{2}\frac{∂z}{∂x}- 3yx\frac{∂z}{∂x}=3yz-3x^{2}

taking common '\frac{∂z}{∂x} on left on side , we get

(3z^{2}- 3yx)\frac{∂z}{∂x}=3yz-3x^{2}

dividing '(3z^{2}- 3yx) on both sides, we get

\frac{∂z}{∂x}=\frac{(3yz-3x^{2})}{3z^{2} -3xy}

<u>Final answer</u>:-

\frac{∂z}{∂x}=\frac{(3yz-3x^{2})}{3z^{2} -3xy}

Find the value of z.<br> X<br> 7<br> Y<br> 3 <br> Z <br><br> Z = √[?]
sweet-ann [11.9K]

Answer:

z = \sqrt{30}

Step-by-step explanation:

using the Altitude- on- Hypotenuse theorem

(leg of big Δ )² = (part of hypotenuse below it ) × (whole hypotenuse)

z² = 3 × (3 + 7) = 3 × 10 = 30 ( take square root of both sides )

z = \sqrt{30}

Is there an x intercept in the equation 60*1.15^x
Natali [406]

Answer:

No

Step-by-step explanation:

The equation 60*1.15^x is an exponential function. Exponential functions do not cross the x-axis unless they have been shifted down through subtraction in the function. All exponential functions have asymptotes that the function approaches but never crosses or touches. This function has an asymptote at the x-axis.

Does anyone know the answer??
Viktor [21]

Answer:

175°

Step-by-step explanation:

If angle x = 058° and angle y = 127° then the bearing A from point O is 360 minus angle x plus angle y.

Solution:

360° - (058° + 127°) = 175°

This is because the complete turn from north to north is 360°.
