So there are 18 coins in total right?(4 quarters+3dimes+5nickels+6 pennies)
So the number of pennies is 6
So probability of pennies (6) out of the whole coins(18) is 6/18 right?
This can be simplified to 2/6(since the highest common factor is 3 and dividing both by 3 gives you 2 and 6)
So probability of a pennie out of the piggy bank is 2/6

A 92 ft path cuts diagonally from Mateo St. to Cove St. It makes an angle of 68° with Cove St. and an angle of 34° with Mateo St
ohaa [14]

Answer:

41.802 feet

Step-by-step explanation:

Given that a  92 ft path cuts diagonally from Mateo St. to Cove St. It makes an angle of 68° with Cove St. and an angle of 34° with Mateo St.

We can visualize a triangle formed by the three streets One side is 92 feet.

Angle opposite 92 feet = 180-68-34 = 78

Let x be length of Cove st and y length of Mateo st.

Using sine angle for triangles,

\frac{92}{sin 78} =\frac{x}{sin 34} =\frac{y}{sin 68}

Simplify to get

x=52.595

y=87.207

Distance saved= x+y-92\\= 139.802-92\\=41.802

AB = x + 3
torisob [31]

Answer:

Step-by-step explanation:

IF it is a SYMMETRIC kite

            CB = CD

         x + 4 = 2x - 1

x - x + 4 + 1 = 2x - x - 1 + 1

                5 = x

  AB = AD

x + 3 = 3x - y

5 + 3 = 3(5) - y

     8 = 15 - y

      y = 7
