Known facts:
A line shaft rotating at 250 rpm, a grinder shaft that turns at 1200 rpm diameter of grinder pulley is 5 inches.
1. Proportion equation
350/1200 = 5/x
2. Cross multiply
1200*5=250*x
x=(1200*5)/250 = (24*50*5)/(5*50) = 24
The big wheel diameter is 24 inches
Out of the two parallelograms shown, we can say that A. Both I and II; congruent diagonals property.
<h3>Which of the shapes is a rectangle?</h3>
Rectangles can be proven to be rectangles by the congruent diagonals property.
This states that rectangles should be able to have diagonal lines extending from all sides within the rectangle that are perpendicular to each other.
These lines should bisect each other. As shown in the daigram, both shapes have that quality and so are both rectangles.

Hope that helped
Step-by-step explanation:
<u>Step 1: Add 2cos(x) to both sides</u>


<u>Step 2: Subtract 9 from both sides</u>


<u>Step 3: Divide both sides by 9</u>


<u>Step 4: Find x</u>


Answer: 
Answer: C
<u>Step-by-step explanation:</u>
f(x) = 26.2 - 0.1x
f(100) = 26.2 - 0.1(100)
= 26.2 = 10.0
= 16.2
f(5-) = 26.2 - 0.1(50)
= 26.2 - 5.0
= 21.2

Answer: D
<u>Step-by-step explanation:</u>
f(x) = 2|x - 3| + 1
2 units right: f(x) = 2|x - (3 + 2)| + 1
= 2|x - 5| + 1
