I you think about it 12a with the 2 on the rope is actually 144 because it’s multiplied by 12 so maybe that helps?

What are the square roots of; (note: i think there are supposed to be 2 each) 36 12 1.96 0.64 400 25/36

Goryan [66]

Answer:

36 : 6 and -6

12 = $2\sqrt{3} , -2\sqrt{3}$

1.96 =1.4 and -1.4

0.64 : 0.8 and -0.8

400 : 20 and -20

25/36 = 5/6 and -5/6

Step-by-step explanation:

we know that

(-x)^2 = x^2

ALSO

(x)^2 = x^2

thus, square of both negative and positive number is same positive number.

_________________________________________________

36 = 6*6

36 = -6*-6

hence

square roots of 36 is both -6 and 6

12 = 4*3 = $2^2*\sqrt{3} *\sqrt{3}$

$\sqrt{12} = 2\sqrt{3}$

also

12 = $-2\sqrt{3} *-2\sqrt{3}$

$\sqrt{12} = -2\sqrt{3}$

___________________________________

1.96 = 196/100 = (14/10)^2

1.96 = 196/100 = (-14/10)^2

hence

$\sqrt{1.96} = 14/10 \ or -14/10$

_______________________________

0.64 = 64/100 = (8/10)^2 = 0.8^2

0.64 = 64/100 = (-8/10)^2 = (-0.8)^2

Thus, square root of 0.64 = 0.8 and -0.8

_________________________________

400 = 20^2

400 = (-20)^2

$\sqrt{400} = 20\\\sqrt{400} = -20\\$

__________________________________

25/36 = (5/6)^2

25/36 = (-5/6)^2

$\sqrt{ 25/36} = 5/6 \\\sqrt{ 25/36} = (-5/6$

Clive is making hamburgers for a cookout. How many 1/4- pounds hamburgers can he make from 2 and 3/4 pounds of ground beef

marshall27 [118]

Answer:

11 1/4- pounds hamburgers can be made from 2 and 3/4 pounds of ground beef.

Step-by-step explanation:

Here, the amount of beef uses in 1 hamburger = 1/4 pound = 0.25 pounds

Total amount of beef available = 2 3/4 pounds

Now, solving the mixed fraction,we get

$2\frac{3}{4} = 2 + \frac{3}{4} = 2 + 0.75= 2.75$

So, the total available beef = 2.75 pounds

Now, $\textrm{ Number of burgers made} = \frac{\textrm{Weight of available beef}}{\textrm{Beef used in 1 hamburger}}$

= $\frac{2.75}{0.25} = 11$

So, <u>the total number of hamburgers made = 11 </u>

Hence, 11 1/4- pounds hamburgers can be made from 2 and 3/4 pounds of ground beef.
