Answer:
C. 301
Step-by-step explanation:
Since the store marked up the price by 115%. You need to first find what is 100% of 140 and then 15% of 140. 100% of 140 is obviously 140. To find 15% of 140, you take 10%, which is 14, then add half of that which is 7 to 14. 15% of 140 is 21. So you add 140 and 21; it gives you 161, which is 115% of 140. Once you add 161 to 140, it gives you a total of 301.
Answer:
The distributive property needs to be applied to determine the value to add to the left side of the equation to balance the sides of the equation
Step-by-step explanation:
There is a factor of a outside of the parentheses on the right has side
We are really adding a( b^2/4a^2) to the right side
Simplifying we are adding b^2 /4a
This is what we need to add to the left side to be fair and equal.
We used the distributive property to determine what we were actually adding to the right side.

Answer:
5 right triangle
6 not a right triangle
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 12^2 = 13^2
25+144 = 169
160 = 169
This is true so this is a right triangle
15^2 +16^2 = 18^2
225 +256 = 324
481 does not equal 324
This is not a right triangle
Hi there! To find the circumference of a circle, you do pi (3.14) times the diameter. To find the area of a circle, you do p (3.14) times radius squared. That means you multiply the radius (half the circle) by itself. If you fo the formulas right, here are the right answers for this situation.
Circumference: 24.806 cm
Area: 48.99185 square centimeters
