Hello!

As we are multiplying by 10^-7, we will move the decimal to the right 7 times. This means we will have 6 0's before our number after the decimal.

0.0000004257

It appears that you switched around the 4 and the 2, but we know what you were referring too.

Therefore, our answer is D.

I hope this helps!

Triangle EFG is dilated by a scale factor of 2/3 to form triangle E'F'G'. What is the measure of side FG?
Illusion [34]

Answer:

Step-by-step explanation:

Since, the given question is incomplete but to solve these kind of questions,

Use the formula of the scale factor,

Scale factor = \frac{\text{Length of one dimension of the dilated image}}{\text{Length of one dimension of the preimage}}

From the question ΔE'F'G' is the image formed by the dilation of preimage ΔEFG.

Therefore, \frac{2}{3}=\frac{F'G'}{FG}

FG = \frac{3}{2}(F'G')

By substituting any value of F'G' given in the question we can evaluate the measure of side FG.

Chris read 1 /4 of a book in the morning, and he read some more at night. By the end of the day, he still had 1 /3 of the book l
Grace [21]

Answer:

5/12

Step-by-step explanation:

1/4 (what he already read)= 3/12

1/3 (what he had left) = 4/12

12/12 (whole book) - 4/12 (what he has left to read)= 8/12 (what he already read+what he read during the day)

8/12 - 3/12 (what he already read)= 5/12 (what he read during the day)

answer: 5/12
