Answer:
0.25 book/hour
Step-by-step explanation:
(1/6)/(2/3)=x/1
*Simplify the equation
1/4=x
*Rearrange the equation
x=1/4
x=0.25 book/hour
Answer:
x = 6
a = 18 ft
b = 36 ft
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
- Factoring/Expanding
- Solving quadratics
<u>Trigonometry</u>
- Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
Given: Right triangle
a = 3x
b = 6x
c = 40
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: (3x)² + (6x)² = 40²
- Evaluate: 9x² + 36x² = 1600
- Combine like terms: 45x² = 1600
- Isolate <em>x </em>term: x² = 320/9
- Isolate <em>x</em>: x = (±8√5)/3
- Evaluate: x = ±5.96285
Since it is not a quadrant triangle, we must use the positive value for <em>x</em>.
<u>Step 3: Find legs</u>
Leg a
- Define: 3x
- Substitute: 3(5.96285)
- Multiply: 17.8885
- Round: 18
Leg b
- Define: 6x
- Substitute: 6(5.96285)
- Multiply: 35.7771
- Round: 36
Answer:
x = 9.2
Step-by-step explanation:
6/cos(57) = 11.01647075 (hypotenuse)
6^2 + b^2 = 11.01647075^2
36 - 36 + b^2 = 121.3626278 - 36
√b^2 = √85.36262784
b = 9.239189783
x = 9.2
Answer:
see below
Step-by-step explanation:
A perpendicular bisector is a line that cuts a line segment connecting two points exactly in half at a 90 degree angle.
To find the perpendicular bisector of two points, all you need to do is find their midpoint and negative reciprocal, and plug these answers into the equation for a line in slope-intercept form.
If you want to know how to find the perpendicular bisector of two points, just follow these steps
midpoint = <u>(X₁ + X₂ </u> , <u> Y₁ + Y₂ )</u>

Answer: The answer would be D
Step-by-step explanation:
This is because all of the models on the graph show in the same place having the same middle but at different heights but not the same standard deviation.
