You have a fifty-fifty chance, so you would expect it to land on heads five times and for it to land on tails five times. Hope this helps!
Answer:
The perimeter of EFGH is 30.5
Step-by-step explanation:
figure ABCD is similar to figure EFGH (hence the ~ sign)
A -> B= <u>12</u>
B -> C= <u>12 </u>
C -> D= <u>12</u>
A -> D= <u>25</u>
EFGH has sides that are half of the size of ABCD
there are two ways you can solve this:
A) divide the perimeter of ABCD by 2 (making it half)
61 / 2 = 30.5
or
B) adding all of the sides together
E -> F =6 so therefore so do F-> G and G -> H
6 + 6 + 6 + 12.5 = 30.5
The distributive properties of addition and subtraction can be used to rewrite expressions for a variety of purposes. In each case, you are distributing the outside multiplier to each number in the parentheses, so that multiplication occurs with each number before addition or subtraction occurs.
