Answer:
2) Subtraction Property of Equality Properties
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Addition Property of Equality - Adding on both sides
- Subtraction Property of Equality - Subtracting on both sides
- Multiplication Property of Equality - Multiplying on both sides
- Division Property of Equality - Dividing on both sides
- Transitive Property - If a = b and b = c, then a = c
- Symmetric Property - If a = b then b = a
Step-by-step explanation:
<u>Step 1: Define</u>
4m + 1 = 7 → 4m = 6
<u>Step 2: Identify</u>
We see that we <em>subtracted</em> on on both sides of the equation. Therefore, we would have to use the Subtraction Property of Equality. Therefore, 2 is our answer.
Answer:
it's not a regular polygon
Step-by-step explanation:
a central angle of a regular polygon is 360/n
360/n=35
n=360/35=10.28
it's not a regular polygon
Answer:
12π in³
Step-by-step explanation:
The right triangle formed by the radius (r), height (x), and slant height (y) is a 3-4-5 right triangle, with the dimension 4 inches being the perpendicular height from the base to the apex. That is, the Pythagorean theorem tells us ...
r² + x² = y²
x = √(y² -r²) = √(25 -9) = 4 . . . inches
The formula for the volume of a cone is ...
V = (1/3)πr²h . . . . . . . . h is the height, what you call x
Your cone has r = 3 in, h = 4 in. Filling in these numbers and simplifying, we get ...
V = (1/3)π(3 in)²(4 in) = 12π in³
The volume of the cone is 12π cubic inches.
Answer option D
Step-by-step explanation:
Two line with the same slope are parallel, if two parallel lines have a different y-intercept they will never cross each other.
(Any two lines with different slopes will always intersect at some point)
