4. figure A is a trapezoid the parallel sides are the bases and the other sides are the legs.
5. sum of interior angles is 360 to find the other answer subtract all known angles from 360.
6. figure B is a parallelogram. if angles are congruent that means they have the same measure. so if angle 1 is 128 then and 4 is 128.
7. the definition of a square : all interior angles each measure 90 degrees.
8. nonconsecutive means they aren't next to each other so in figure D angles d and b and angles a and c for figure E angle j and m and angle n and l
9. figure e is concave that means its got an angle that "caves in"
-13 because if you 33 and subtract 46 you would have -13 sorry dont really know how to explain
Sam's money will double faster.
The formula for compound interest is
A=p(1+r)ˣ, where A is the total amount in the account, p is the principal you invest, r is the interest rate as a decimal, and x is the amount of time.
If we want to represent the money being doubled, we would use 2p for A:
2p=p(1+0.09)ˣ
2p=p(1.09)ˣ
Divide both sides by p:
2p/p = p(1.09)ˣ/p
2 = 1.09ˣ
Using logarithms to solve this,
The formula for simple interest is
I = prt
If we want to find the amount of time to double the principal, this means the amount of interest would be equal to the principal invested:
p = p(0.09)t
Dividing both sides by p,
p/p = p(0.09)t/p
1 = 0.09t
Dividing both sides by 0.09,
1/0.09 = t
11.11 = t
