Answer:
Cost: $14.349
Markup: $15.649
Step-by-step explanation:
1. Rewrite the percent as decimal. Divide it by 100, as following:
109/100=1.09
3. Now, knowing that Baby blankets sell for $29.99 after a markup rate based on cost of 109%, you can write the following expresion:

Where x is the cost.
4. You must solve for x, then, you obtain:

5. The markup is:

Answer:
a) 1/800 or 0.00125
b) i) 0.0013
ii) 0.001
c) 60%
Step-by-step explanation:
T = [tan(2×30)+1][2cos(30)-1] ÷ (y²-x²)
T = (tan60 + 1)(2cos30 - 1) ÷ (41² - 9²)
T = (sqrt(3) + 1)(sqrt(3) - 1) ÷ 1600
T = (3-1)/1600
T = 2/1600
T = 1/800
T = 0.00125
Error: 0.002 - 0.00125
0.00075
%error
0.00075/0.00125 × 100
60%
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x + 5 ← is in slope- intercept form
with slope m = 
• Parallel lines have equal slopes, hence
y =
x + c ← is the partial equation of the parallel line
To find c substitute (- 6, 0) into the partial equation
0 = - 2 + c ⇒ c = 0 + 2 = 2
y =
x + 2 → C
Answer:
Not Independent
Step-by-step explanation: Because the red ballsdon't have to worry because they have a larger number
-8y = -4x + 16
Y = 4/8x - 2
