Janelle has 5 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the
VikaD [51]

Answer:

The distance cover by him walking back is 11.25 miles

Step-by-step explanation:

Given as :

Time for Janelle to spend on training = 5 hours

The  running speed of Janelle = 9 mph

The walking back with 3 mph

Let The distance for running and walking is same i.e  D miles

SO, Time = \frac{Distance}{Speed}

∴  5 =  \frac{D}{9} +  \frac{D}{3}

Or, 5 × 9 = D + 3 D

Or, 45 = 4 D

∴   D = \frac{45}{4} = 11.25 miles

Hence The distance cover by him walking back is 11.25 miles   Answer

Please help solve 1, and 2
Vadim26 [7]

Answer:

Step-by-step explanation:

1). WXYZ is a rectangle,

  Properties of a rectangle,

  i). Opposite sides are equal and parallel.

  ii). All interior angles measure 90°.

  iii). Diagonals are equal in measure.

a). WY = ZX = 30

 Therefore, ZT = \frac{1}{2}(ZX)

                    ZT=15

b). WY = ZX = 45

c). Since, WY = ZX,

    (4b - 16) = (3b + 5)

    4b - 3b = 16 + 5

     b = 21

2). GOAT is a rhombus and m∠OGA = 35°,

    a). m∠TGA = m∠OGA = 35°

    b). m∠GXO = 90°

    c). m∠GXT = 90°

    d). Since adjacent angles of a rhombus are supplementary,

         m∠OGT + m∠GTA = 180°

         70° + m∠GTA = 180°

         m∠GTA = 110°

         m∠GTO = \frac{1}{2}(m\angle GTA)

                        = \frac{1}{2}(110^{\circ})

                        = 55°

     e). Since, opposite angles of a rhombus are equal,

          m∠OGT = m∠OAT = 70°

     f). m∠GOA = m∠GTA = 110°
