Write a fraction equivalent to 60mi/4hr that has 2 in the denominator

30mi/2hr

Explanation: just divide both by two. It won’t always work like this. You can’t always divide something by 2 to get 2. Find a number that will go into the denominator two times and divide the numerator by it also.

point f has coordinated (8,-1), point g is symmetric to point f with respect to the line y=x, what are the coordinates of point
Alex17521 [72]
If points f and g are symmetric with respect to the line y=x, then the line connecting f and g is perpendicular to y=x, and f and g are equidistant from y=x.

This problem could be solved graphically by graphing y=x and (8,-1).  With a ruler, measure the perpendicular distance from y=x of (8,-1), and then plot point g that distance from y=x in the opposite direction.  Read the coordinates of point g from the graph.

Alternatively, calculate the distance from y=x of (8,-1).  As before, this distance is perpendicular to y=x and is measured along the line y= -x + b, where b is the vertical intercept of this line.  What is b?  y = -x + b must be satisfied by (8,-1):  -1 = -8 + b, or b = 7.  Then the line thru (8,-1) perpendicular to y=x is     y = -x + 7.  Where does this line intersect y = x?

y = x = y = -x + 7, or 2x = 7, or x = 3.5.  Since y=x, the point of intersection of y=x and y= -x + 7 is (3.5, 3.5).

Use the distance formula to determine the distance between (3.5, 3.5) and (8, -1).  This produces the answer to this question.

The sides AB , BC , and AC of a △ABC are tangent to a circle at points P, Q, and R respectively. Find AP, PB, BQ, QC, CR, and RA
Vsevolod [243]

Answer:

AP = RA = 1.5 cm

PB = BQ = 8.5 cm

QC = CR = 3.5 cm

Step-by-step explanation:

The distance from the vertex to the two nearest tangent points is the same. If we say the distance AP = RA = x, then PB = BQ = 10-x, and QC = CR = 5 -x.

Since we know

BQ +QC = 12

We can substitute the above expressions involving x to find what x is.

(10 -x) +(5 -x) = 12

15 -2x = 12

x = (15 -12)/2 = 1.5

This tells us ...

AP = RA = 1.5 cm

PB = BQ = 8.5 cm

QC = CR = 3.5 cm
