A=(pie) squared times 1/2
I think this is correct but I’m not sure
Wel have to use the Pythagorean theorem (a^2) + (b^2) = (c^2)
look at the top triangle inside the big triangle. we know it's 2 sides but not the hypotenuse. one side would be 25 - 9 = 16 and other side is x. So so from theorem we know
16^2 + x^2 = h^2
with bottom triangle we can see the same thing but with 9 and x as the sides so:
9^2 + x ^2 = H^2 (capital H to distinguish them)
we also know that in the main triangle:
h^2 + H^2 = 25^2
now all we have to do is find a way to use these 3 equations to get the answer
we know what h^2 and H^2 both equal and can plug them into equation in orsee to get rid of one and solve for the other. So we use:
9^2 + x ^2 = H^2
and plug it into
h^2 + H^2 = 25^2
and get
h^2 + 9^2 + x ^2 = 25^2
solve for h^2
25^2 - x^2 - 9^2 = h^2
now plug what we got for h^2 into:
16^2 + x^2 = h^2
and get:
16^2 + x^2 = 25^2 - x^2 - 9^2
2x^2 = 25^2 - 16^2 - 9^2
2x^2 = 288
x^2 = 144
x = 12
there is your answer
Answer: 140%
Step-by-step explanation:
From the question, we are informed that price increases from $50 to $120. The percentage change will be:
= (New price - Old price)/Old price × 100
= (120 - 50)/50 × 100
= 70/50 × 100
= 1.4 × 100
= 140%
The answer is: False, because, by definition, the distance (which is a scalar quantity) is the absolute value of the displacement. This means that the distance cannot be negative, but the displacement (which is define as a vector quantity can be positive or negative.
There are seven days in the week, and the 4th of July could be on any of them, so it has a 1/7 chance of being on a Sunday.
