Answer:
Step-by-step explanation:
Each tick is 0.1
So for example:
2.8 would be the eighth tick between 2 and 3.
-0.9 would be between 0 and -1 and will be the ninth tick.
Same as before, to make the formula do
t(1) * (r)^n-1
So 5 * (-1/2)^n-1
Therefore
5*(-1/2)^5
0.078125
13. To find the angle of WZY you would have to grab the angle of a straight line (180) and subtract it from the already shown angle of 105. 180 - 105 = 75. 75 is the measure of WZY
14. WZ has a measure of 24 since the parallel side is also 24 (not too sure about this one)
15. XYZ Has the same angle as its corresponding angle of 105. The angle is also 105
ANSWER
$18,000
EXPLANATION
Ginny has $10,000 in a savings account.
The interest is 4% simple interest.
We want to calculate Ginny's total account balance after 20 years.
To do this, we will first caluclate the interest and then we will add it to the initial balance.
To calculate Simple Interest, we use:

P = principal = $10000
R = rate = 4%
T = time = 20 years
Therefore:

Therefore, her account balance after 20 years is:
Amount = $10000 + $8000 = $18,000
<span>3x + y= 17 (a)
4x + 2 y = 20 (b)
Multiply (a) by 2:
6x + 2y = 34 (a)
4x + 2y = 20 (b)
make: (a) - (b)
2x = 14 -----> x =7
-------------------------------
Replace the value of x = 7 in one of anterior equation:
</span>3x + y= 17
3 x 7 + y = 17
21 + y = 17
y = 17 - 21
y = -4
