Answer
Find out the how much twine will he needs to pack 29 cartons today .
To proof
As given
uhammad, a shipping and receiving clerk, uses 1 yard, 2 feet, 4 inches of twine to wrap each carton he packs.
As given in the question
Convert the answer to larger units .
As between yard is the largest unit between yard, feet and inches.
and
Convert 2 feet into yard
Convert 4 inches into yard
twine to wrap each carton packs
L.C.M of (3 , 36) = 36
than the equation becomes
=1.77777778 yard
Now twine to wrap pack 29 cartons = 29× 1.77777778
= 51.5555556 yard
Now twine to wrap pack 29 cartons is 51.55 yard ( approx)
Hence proved
Cross-multiply:
7 * 3 = 5 * x
Divide each side by 5 :
X = 7 * 3 / 5 = 4.2
Step-by-step explanation:
x = 112°
y = z = 180° - 112° = 68°
Answer:
Step-by-step explanation:
(x^2+y^2)^2=(x^2)^2+2x^2y^2+(y^2)^2
Adding and substracting 2x^2y^2
We get
(x^2+y^2)^2=(x^2)^2+2x^2y^2+(y^2)^2 +2x^2y^2-2x^2y^2
And we know a^2-2ab+b^2=(a-b)^2
So we identify (x^2)^2 as a^2 ,(y^2)^2 as b^2 and -2x^2y^2 as - 2ab. So we can rewrite (x^2+y^2)^2=(x^2 - y^2)^2 + 2x^2y^2 + 2x^2y^2= (x^2 - y^2)^2+4x^2y^2= (x^2 - y^2)^2+2^2x^2y^2
Moreever we know (a·b·c)^2=a^2·b^2·c^2 than means 2^2x^2y^2=(2x·y)^2
And (x^2+y^2)^2=(x^2 - y^2)^2 + (2x·y)^2
Wait i will tell you soon dont worry, im out now sorryy ^.^
