Answer:
first blank: c(x) = 45x + 14
second blank: 7
Step-by-step explanation:
explanation for second blank:
set up the equation equal to 329:
45x + 14 = 329
subtract 14 from both sides:
45x = 315
divide by 45 to leave x alone:
x = 7

Answer:
23 in
Step-by-step explanation:
Volume of a Cube: V = a³
Step 1: Define
V = 12,167 in³
a = ?
Step 2: Solve for side length <em>a</em>
- <u>Substitute:</u> 12,167 = a³
- <u>Cube root both sides:</u> 23 = a
- <u>Rewrite:</u> a = 23
Step 3: Check
<em>Plug in a to verify it's a solution.</em>
- <u>Substitute: </u>V = (23 in)³
- <u>Evaluate:</u> V = 12,167 in³
A² + b² = c² ⇒ right triangle
a² + b² < c² ⇒ obtuse triangle
a² + b² > c² ⇒ acute triangle
a = 12 ft ; b = 15 ft ; c = 20 ft
12² + 15² = < > 20²
144 + 225 = < > 400
369 < 400 OBTUSE TRIANGLE
√369 = 19.21
20 - 19.21 = 0.79
<span>It is an obtuse triangle. About 0.8 foot needs to be removed from the 20-foot board to create a right triangle.</span>
20% = 0.20
50 * 0.20 = $10 discount
50 - 10 = 40
The price after 20% discount is $40
