600%? Would it be if one is 100%?

sp2606 [1]3 years ago

It is 600% should be the answer:

because one block of tape diagram is 100 then 6 times 100 is 600.

Use the Pythagorean theorem:

$a^2+(2\sqrt3)^2=(4\sqrt3)^2\\\\a^2+2^2(\sqrt3)^2=4^2(\sqrt3)^2\\\\a^2+4\cdot3=16\cdot3\\\\a^2+12=48\ \ \ \ |-12\\\\a^2=36\to a=\sqrt{36}\\\\\boxed{a=6\to C.}$

Used:

$(a\cdot b)^n=a^n\cdot b^n\\\\(\sqrt{a})^2=a$

EFGH is a rhombus. Given EG = 16 and FH = 12, what is the length of one side of the rhombus?

Black_prince [1.1K]

Answer:

Step-by-step explanation:

It is given that EFGH is a rhombus and EG = 16 and FH = 12.

We know that the diagonals of the rhombus are the perpendicular bisectors, therefore OF=6, OH=6, OE=8 and OG=8.

Now, using the Pythagoras theorem in ΔOFG, we have

$(FG)^{2}=(OG)^{2}+(OF)^{2}$

$(FG)^{2}=(8)^{2}+(6)^{2}$

$(FG)^2=64+36$

$FG=\sqrt{100}$

$FG=10$

Thus, the value of the side of the rhombus will be 10 units.

Hence, option C is correct.
