This could be an adding fractions problem. We can add the two fractions together and then determine how many miles she walked.

9 1
--- +
10 3

First, we need to find a common denominator. It would be 30, since this is the smallest number both 3 and 10 go into.

So, after that, we need to multiply each numerator by the number we needed to multiply our denominator by to get to 30.

So, 10 times 3 equals 30. So, we need to multiply 9 by 3 as well, which is 27.

Our new fraction here would be:

27

30

Next, to get 30, we need to multiply 3 by 10 to get 30. So, we also need to multiply 1 by 10, which is 10.

Our new fraction would be:

10
---
30

So lets take a look at our new equation.

27 10
--- +
30 30

Lets add them together. Remember the denominators need to stay the same:

37

30

Now that we have an improper fraction, we need to simplify it. 37 goes into 30 once, and we have 7 left over.

So, our final answer would be:

1 and 7
of a mile.
30

Answer from: Quest

angle q= 92 degree

step-by-step explanation:

the solution is in the picture

when a quadrilateral is inscribed in a circle, the opposite angles are supplement to each other. in other words, the sum of the 2 angle is 180 degree

Answer from: Quest

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

= 2×(-2)+(-8)×(6)+(-8)×(-5)

= -4-48+40

= -12

hence, v.w= -12
