Find the area of a square that is 1/2 yd on a side.

victus00 [196]

Answer:  " $\frac{1}{4}$ yd²  " .

______________________________________________________
The area of the square is:  " $\frac{1}{4}$ yd²  " .

or; write as: " 0.25 yd² " .
______________________________________________________
Explanation:
______________________________________________________
A "square", by definition, is a quadrilateral and a rectangle, with 4 (four) equal sides and 4 (four) equal angles.

The formula for the area of a square is:

" A = s² " ;

in which: " A = area of the square" ;

(in " square units "; in our case, " square yards " ;
or, write as: " yd² " .
______________________________________________________
" s = side length = " 1/2 yd " ; {given} .
______________________________________________________
To find the "Area, "A" ; of the square, which is what the question asks:

→ We plug in the given / known values into the formula, & solve:

→ " A = s² " ;

→ A = (1/2 yd)² ;

=  (1/2)² * yd² ;

  = (1/2) * (1/2) * yd² ;

   = (1 * 1) / (2 * 2) * yd² ;

  = " 1/4 yd² " .

Raul has 56 bouncy balls. He puts three times as many balls into red bags as he puts into green gift bags. If he puts the same n

Sati [7]

If we divide 56 by 4 we get 14. Why by4? So that one number is 3 times the other So he had 14 balls that went into the green bags and 42 (56-14) that went into the red bags. We could just answer the question and say 14 but I think they want to know how many in each green bag.
14 and 42 don't work because they are not the same number of balls. What number is a common factor? 7 is,
We could have 2 green bags and split the 14 balls into 2 groups of 7 and with the remaining 42 - put them into 6 red bags of 7 each.
And so the answer to your question is:
7 ball in each bag = 2 bags are green, and 6 bags are red
14 balls + 42 balls = 56 bouncy balls

the area of the first quadrant bounded by the y-axis, the line y=4-x, and the graph of y=x-cosx is approximately

zzz [600]

The curves $y=4-x$ and $y=x-\cos x$ intersect at approximately $x\approx1.8582$ . The area is then

$A\approx\displaystyle\int_0^{1.8582}((4-x)-(x-\cos x))\,\mathrm dx=\int_0^{1.8582}(4-2x+\cos x)\,\mathrm dx\approx4.9389$

45.3297 rounded to the nearest tenth would be?

Alex

45.3297 rounded to the nearest tenth is 45.3
3 is in the tenths place, so you look at the number to the right of it. If that number is 5 or more, you round up. If the number is 4 or less, you round down. So you round 45.3297 down to 45.3
