Answer:
10
Step-by-step explanation:
The distance formula is useful.
d = √((x2 -x1)^2 +(y2 -y1)^2)
d = √((7 -1)^2 +(12 -4)^2) = √(6^2 +8^2) = √(36 +64) = √100
d = 10
The distance between P and Q is 10.

<em>Additional comment</em>
You may recognize the run : rise ratio of 6 : 8 = 3 : 4. This suggests a 3-4-5 right triangle with a scale factor of 2. If you're familiar with that Pythagorean triple, you can write down the answer as soon as you see the rise and run numbers.

I’m wrong but I need points to ask a question
Breanna used
pounds of clay for her project.
Step-by-step explanation:
Step 1; First, we must convert the mixed fractions into improper fractions. To do that we multiply the whole number with the denominator and add with it the numerator while the denominator remains the same. To convert this fraction 1
, we multiply 1 with 8 and then add 4 and keep the 8 as the denominator so we get
1
= (1 × 8) + 5 / 8 =
.
Step 2; After conversion, it's just a matter of subtraction. To calculate the clay she used for her project, we subtract the clay she had after from the clay she had before doing the project. While subtracting two fractions, if denominators are equal we subtract the numerators and keep the denominator the same.
