Answer:
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean Theorem to solve for the sides.
where <em>a</em> and<em> b</em> are the legs and <em>c</em> is the hypotenuse. In this triangle, we know the legs are 9 centimeters and 11 centimeters, or:
Substitute these values into the formula.
Solve the exponents.
- (9 cm)²= 9 cm*9 cm=81 cm²
- (11 cm)²= 11 cm*11 cm= 121 cm²
Add the values on the left side.
Since we are solving for c, we must isolate the variable. It is being squared and the inverse of a square is the square root. Take the square root of both sides.
We are told to round to the nearest tenth.
The 1 in the hundredth place tells us to leave the 2 in the tenth place.
The hypotenuse is equal to <u>14.2 centimeters.</u>

its A

Its a because its A =)
Answer: The final answer to this question is 4:3
Step-by-step explanation:
The definition of a ratio is "the quantitative relation between two amounts showing the number of times one value contains or is contained within the other." In English, it's essentially how many "things" there are for every "other thing" there is. In this case, for every 8 girls there are, there are also 6 boys. There are many ways to write a ratio but the main one is with a colon.
So the ratio would be written like this 8:6
However, the statement requires it to be in simplest form so we need to simplify the ratio. We do that much like simplifying a fraction. Find the least common denominator, then divide both values by it. In this case the LCD is 2. So all we need to do now, is divide both the numbers in half, then we have our simplified ratio.
See :
8/2 = 4
6/2 = 3
So our new and final ratio is 4:3
Hope this helped you understand :)
Answer:
$13.5
Step-by-step explanation:
Given data
We are given that the tax per CD is $1.30
Hence for the 3 CDs the total tax = 3*1.3= $3.9
Also, the cost of the three CDs before tax = 44.4-3.9
=$40.5
Hence the cost of each CD before tax is
=40.5/3
=$13.5
