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>

Answer:
1,114 people
Step-by-step explanation:
The equation 
is the equation of the regression line that predicts the number of people attending a county fair, where x is the number of years after 2000.
To find the number of people that are expected to attend the fair in 2026, we determine how many years have passed and substitute into the equation.
From 2000 to 2026,
have passed.
The expected number who will attend the fair in 2026 is
To the nearest whole number 1,114 people will attend in 2026
To find the volume,we would first need to find the height of square pyramid, by it's base edge and slant height using Pythagoras theorem:
We can then use the pyramid formula to find the volume:
In this case,the volume will be:
10×_/69×1/3
=27.68874...
≈27.7 units^3
