Terryn has 25 one-dollar bills and wants to give an even amount to each of his two children. How many bills do each of Terryn's
aleksley [76]

Answer:

Number of one-dollar bills each child gets: 12 dollars

Dollars left over: 1 dollar

Step-by-step explanation:

25/2=12.5

so round down to 12 cause 13(2) is 26 and you only have 25.

so 12(2)=24.

Each kid will get 12 dollars and there will be 1 dollar left over.

If line AD is a tangent to circle B at point C, and m∠ABC = 55º, what is the measure of ∠BAD?
4vir4ik [10]
The tangent AD at point C forms a right angle to circle B, such as ∠ACB=90° and ∠ABC=55°.

We also know that the summation of all angles in a triangle is 180°. Thus we have the expression below:
180°=∠ABC + ∠ACB + ∠BAD
180°=55°+90°+∠BAD
∠BAD=35°

Therefore, the answer is 35°.
