There are 13 clubs in a deck of card and 13 non face cards.
P(club of non face card) = 13/52 + 13/52 = 26/52 = 1/2

An isosceles triangle has an angle that measures 92° which other angles could be in that isosceles triangle choose all that appl

nignag [31]

Answer:

Step-by-step explanation:

The two base angles cannot both be 92 degrees because they would add up to 184 which is more degrees than any triangle has. The apex angle (the top angle) therefore has 92 degrees.

The base angles are equal and found as follows.

2*b + 92 = 180 Subtract 92 from both sides

2b +92-92 = 180-92

2b = 88 divide by 2

2b/2=88/2

b = 44

The only angle measurement that fits is 44

Ivan has cut 19 pieces of reinforcing bar (rebar) that are each 1.14 meters long. What is the total length of the rebar used fo

madreJ [45]

Answer:

The total length of rebar used is 21.66 meters.

Step-by-step explanation:

Given:

Ivan had cut a reinforcing bar in 19 pieces and length of each bar is 1.14 meters.

Number of pieces = 19

Length of each piece = 1.14

We need to find the total length of reinforcing bar.

To calculate the total length we will multiply number of pieces with length of each piece.

Hence,

Total length of rebar = Number of pieces × Length of each piece = $19\times1.14 = 21..66 m$

Rounding to nearest hundred = 21.66 m

Hence the total length of reinforcing bar is 21.66 meters.
