Answer:

The scale factor is 0.5

Step-by-step explanation:

Figure A is 4 blocks wide and 4 blocks tall, Figure B is 2 blocks tall and 2 blocks wide, to get Figure B from Figure A you would need to scale it down by half (0.5)

Answer:

x = 3\sqrt{13} = 10.8

Step-by-step explanation:

Both problems are done the same way.  I will do the first one and you do the second one.  OK?

Move the radius x to make a right triangle.  The 6 unit segment bisects the chord.  So, the legs of the right triangle are 6 and 9

The use the Pythagorean theorem to find x, which is the hypotenuse of the right triangle.   Now,

6^{2}  + 9^{2}  = x^{2}

x^{2} = 36 + 81 = 117\\x = \sqrt{117} = 3\sqrt{13}= 10.8

None of the answer choices are to the nearest tenth.  So, I am confused about that.

In  the second problem, the answer should be 11.2

One-third of a storeâs inventory is childrenâs clothing. Two-fifths of its inventory is womenâs clothing. What fraction of the t
Eva8 [605]

Answer:  C. 11/15

Step-by-step explanation:

Given : The fraction of stores inventory is children's clothing=\dfrac{1}{3}

The fraction of stores inventory is women's clothing=\dfrac{2}{5}

Since both events are independent.

Therefore, the fraction of the total inventory is children's or women's clothing =  (Fraction of stores inventory is children's clothing ) + (Fraction of stores inventory is women's clothing )

=\dfrac{1}{3}+\dfrac{2}{5}=\dfrac{5+2(3)}{15}

=\dfrac{11}{15}

∴ The fraction of the total inventory is children's or women's clothing =\dfrac{11}{15}

Hence, the correct answer is C. 11/15 .
