Answer:

Step-by-step explanation:

there are 60 seconds in a minute so about 6 9 seconds in a minute. then there is 12 pages per 9 seconds and since there is 6 9 seconds then you can just multiply 6 by 9 to get the answer 72

4x^1/2 to radical form

Lyrx [107]

$x^ \frac{m}{n}= \sqrt[n]{x^m}$
pemdas, so exponent first before multiply
4(x^1/2)=4x^2
this is different from
(4x)^1/2

so

$x^ \frac{1}{2}= \sqrt[2]{x^1}$
times that by 4
4√x

Please hurry I will mark you brainliest

Slav-nsk [51]

Step-by-step explanation:

Let grandson's age be x.

Let grandpa's age be y {equation : y = 8+5x}

so,

x + y = 88

or, x + 8+ 5x = 88 (substituting the value of y)

or, 6x + 8 =88

or, 6x = 88-8

or, 6x = 80

or, x = 80/6

so, x = 13.33

so grandson's age = 13.33

grandpa's age = 8 + 5x = 8 + (5×13.33) = 74.65 yrs

A 20-gallon salt-water solution contains 15% pure salt. How much pure water should be added to it to produce a 10% solution?

Elanso [62]

15% of 20 gal = 0.15 * 20 gal = 3 gal, so the solution contains 3 gal of salt.

If we add x gal of water to the solution, we end up with (20 + x) gal of solution. We want the new mixture to have a concentration of 10%, or

10% of (20 + x) gal = 0.1 * (20 + x) gal = 2 + 0.1x gal

of salt.

The amount of salt in the tank hasn't changed. Solve for x :

2 + 0.1x = 3

0.1x = 1

x = 10 gal
