Answer:

  • 9 ft 8 in
  • 12 gal 3 qt
  • 8 yd 1 ft 10 in

Step-by-step explanation:

There are several different ways you can work problems like this. The method you may prefer may be different from the one I prefer. At least, they include ...

  • You can treat the smaller units as a fraction of the larger unit: 23 7/12 -13 11/12. Then subtracting mixed numbers proceeds in any of the usual ways. You may even be able to use a calculator for this.
  • You can "subtract by adding": 8 inches added to the subtrahend makes it 14 ft 7 in; then adding 9 ft makes it 23 ft 7 in. The difference is then seen to be 9 ft 8 in.
  • You can subtract the different units separately, then "make change" or "borrow" as required. 23'7" -13'11" = 10'(-4)" = 9'8". (This is probably the method I prefer.)
  • An on-line calculator may be able to handle the mixed units to your satisfaction (see attached).

___

1. There are 12 inches in a foot.

  23 ft 7 in - (13 ft 11 in) = (23 -13) ft (7 -11) in = 10 ft (-4) in = 9 ft 8 in

__

2. There are 4 quarts in a gallon.

  18 gal 2 qt - (5 gal 3 qt) = (18 -5) gal (2 -3) qt = 13 gal (-1) qt = 12 gal 3 qt

__

3. There are 3 feet in a yard and 12 inches in a foot.

  21 yd 1 ft 7 in -(12 yd 2 ft 9 in) = (21 -12) yd (1 -2) ft (7 -9) in

  = 9 yd (-1) ft (-2 in)

  = 8 yd 2 ft (-2) in

  = 8 yd 1 ft 10 in

Answer:

RC = 40

Step-by-step explanation:

Note that the circumcentre is equally distant from the triangle's 3 vertices.

That is : PC = RC = QC

Equate any pair and solve for x

Using RC = PC, then

5x - 15 = 3x + 7 ( subtract 3x from both sides )

2x - 15 = 7 ( add 15 to both sides )

2x = 22 ( divide both sides by 2 )

x = 11

Hence

RC = (5 × 11) - 15 = 55 - 15 = 40 units

Show that triangle MPT =Triangle MTP​
exis [7]

Unusual notation.  I won't fuss with it.

a. We have isosceles PRT, so angle  RPT = angle RTP.

By the definition of angle bisector, angle MTP = angle MTF, and angle MPT = angle MPU.

We have m angle RTP = m angle MTF + m angle MTP = 2 m angle MTP

Similarly, m angle RPT = 2 m angle MPT

2 m angle MTP = 2 m angle MPT

angle MPT = angle MPT

That's the first part.

b. That makes MPT isosceles.

c. 2x+124=180

2x = 56

x = 28 degrees

MTP = 28 degrees

d.  We have angle RPT=angle RTP=56 so PRT=180-2(56)=68 degrees

PUT = 180 - UTP - UPT = 180 - 28 - 56 = 96 degrees

Bad drawing, PUT looks acute.

angle PRT = 68 degrees, angle PUT = 96 degrees
