Issouf claims that the scale factor is 1/2. which statement about his claim is correct? a- he is correct because cb is 4 and c' b' is 2. the scale factor is c'b'/cb = 2/4 = 1/2b- he is correct because he needs to subtract 2 from each side. a reduction has a scale factor that is a fraction, so it must be 1/2c- he is incorrect because it is 3. cb is actually 2+4 or 6. so one needs to multiply the pre-image length by 3 to get the image; 3 is the scale factor. d- he is incorrect because the scale factor is 1/3. cb is actually 2 + 4 = 6. cb is the pre-image, so the scale factor is c'b'/cb = 2/6 = 1/3.

The correct option is D.

Step-by-step explanation:

It is given that Issouf claims that the scale factor is 1/2.

From the given figure it is clear that

The scale factor of a figure is

The scale factor is 1/3 because CB is actually 2 + 4 = 6.

Therefore the correct option is D.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
