Answer:

23/6 or 3 5/6

Step-by-step explanation:

1 2/3 = 5/3

2 1/6 = 13/6

To add these we need to make the denominators the same. To do this we need to double the 5/3 and that will make the denominator 6 and then will be able to be added.

5/3= 5x2/ 3x2= 10/6

10/6 + 13/6 = 23/6 or 3 5/6

Hope I was able to help!

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

$x=y-2$

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

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

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

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

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

substitute in the formula

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

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

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

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

The positive real number is

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

Find the value of y

$y=x+2$

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

$y=3\sqrt{5}$

A diver descends 130 feet below the surface over 35 minutes. what was his average rate of descent

attashe74 [19]

I believe you would do the feet ,130, divided by the minutes ,35, to get how many feet per minute. It would get you a never ending decimal of 3.714285. So every minute he would drop about 4 feet. You will have to put it how it says to for what your answering is. If it says round to the whole number then he would drop 4 feet, but I hope this helps you in any way :)
