pshichka [43]

Answer:

The correct option is B. The length of OB' is 3 units.

Step-by-step explanation:

The rule of dilation is D₀,₄. It means dilation by scale factor 4 with center of dilation is origin.

$\text{Scale factor}=\frac{\text{Distance between center and any point of the image}}{\text{Distance between center and corresponding point of the Preimage}}$

$\text{Scale factor}=\frac{OB'}{OB}$

$4=\frac{OB'}{\frac{3}{4}}$

$4\times \frac{3}{4}=OB'$

$3=OB'$

The length of OB' is 3 units. Therefore the correct option is option is B.

Correct answer gets brainlies show step by step

photoshop1234 [79]

Answer:

Step-by-step explanation:

Half of the 16 oz = 8 oz of peanuts.

2 oz are almonds.

1 oz is cashews.

3 oz are raisins.

So, we know 8+2+1+3 = 14 oz of stuff in detail.

We're told the rest is chocolate chips, which means 16 - 14 = 2 oz.

BUT always read the question.

It does not ask the weight of the chocolate chips. It asks the fraction.

That is

2/16 = 1/8
