The amount of fluid excreted as urine each day averages approximately less than how many liters?

Dafna11 [192]

Answer: Averages less than 2litres per day

Step-by-step explanation:

The normal range of urine excreted per day is between 1 to 2 litres, but the kidney must produce a minimum urine volume of 500mL per day, to get rid of body waste, anything below that is abnormal, and not good for the body

60% of a sum of money is $120.00. calculate 40% of tha same sum of money

Cerrena [4.2K]

If 60% is $120, then by diving both the percent and the balance by 3, we se that 20% is $40.

Now multiply the 20% and $40 by 2, and you see 40% is $80.

1) "Subtract -7a+1 from 7+a" means -7a+1 is getting taken away from 7+a, so this can be mathematically expressed as:

Starting expression: (7+a)-(-7a+1)

Distributive property with negatives: 7+a+7a-1

Combine like terms: 6+8a

So the answer for the first one is 6+8a

2) "Subtract -4v-2 from -2-5v" means -4v-2 is getting taken away from -2-5v, so this can be mathematically expressed as:

Starting expression: (-2-5v)-(-4v-2)

Distributive property with negatives: -2-5v+4v+2

Combine like terms: -v

So the answer for the second one is -v

Hope these explanations are clear.

A positive real number is 2 less than another. When 4 times the larger is added to the square of the smaller, the result is 49.

Kobotan [32]

Answer:

The numbers are

$-2+3\sqrt{5}$ and $3\sqrt{5}$

Step-by-step explanation:

Let

x -----> the smaller positive real number

y -----> the larger positive real number

we know that

A positive real number is 2 less than another

so

$x=y-2$

$y=x+2$ ----> equation A

When 4 times the larger is added to the square of the smaller, the result is 49

so

$4y+x^2=49$ ----> equation B

substitute equation A in equation B

$4(x+2)+x^2=49$

solve for x

$x^2+4x-41=0$

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^2+4x-41=0$

so

$a=1\\b=4\\c=-41$

substitute in the formula

$x=\frac{-4\pm\sqrt{4^{2}-4(1)(-41)}} {2(1)}$

$x=\frac{-4\pm\sqrt{180}} {2}$

$x=\frac{-4\pm6\sqrt{5}} {2}$

$x=-2\pm3\sqrt{5}$

so

The positive real number is

$x=-2+3\sqrt{5}$

Find the value of y

$y=x+2$

$y=-2+3\sqrt{5}+2$

$y=3\sqrt{5}$
