Answer:
The answer is A.
Step-by-step explanation:
First, divide two by nine. The result is the decimal zero point two repeating.
Second, the digit that repeats is two. So, since two is one digit, the answer is A.
The ends of the rectangle = 10*10*2 = 200
The long sides and bottom of the rectangle = 12*10*3 = 360
Vertical end of the triangle = 5*10 = 50
The sides of the triangle = 12*5*1/2*2 = 60
Triangle slope = 13*10 = 130
Total = 200 + 360 + 50 + 60 + 130 =
800 in sq
The nickels in the envelope is $0. 12
<h3>How to determine the number</h3>
From the information given, we have that;
Dimes + nickels = $1. 20
1/4 dimes + dimes = $ 1. 35
Let dimes = d
Nickels = n
d + n = 1. 20 equation a
d/4 + d = 1. 35 equation b
Make 'd' subject from equation a
d = 1. 20 - n
Substitute into equation b
1. 20 - n/ 4 + 1. 20 - n = 1. 35
0. 3 - 0. 25n + 1. 20 - n = 1. 35
collect like terms
- 1. 25n = 1. 35 - 1. 5
- 1. 25 = - 0. 15
n = -0. 15/ -1. 25
n = 0. 12
Thus, the number of nickels in the envelope is $0. 12

Answer:
Step-by-step explanation:
Both legs are equal, which implies the triangle is a 45-45-90.
The hypotenuse of this triangle is:
All the x values are made negative
X = 4
F(x) = 2x
F(4) = 2(4)
F(4)= 8
X = 4 (still)
F(-x) = 2(-x)
F(-4) = 2 (-4)
F(-4) = -8
