Answer:
80.029
Step-by-step explanation:
(8)(10)+2+1/100+9(1/1000)
=80+2+1/100+9(1/1000)
=80+201/100+9(1/1000)
=8201/100+9(1/1000)
=8201/100+9/1000
=82019/1000
Answer:
11.40
Step-by-step explanation:
If we were to divide the shape into a rectangle and triangle, we would have the base of the triangle as 9 because two sides of the rectangle are equal, and 7 for the side because two sides of rectangle are equal and 14/2 is 7. Now we have two sides of a triangle 9 and 7. We know X is the hypotenuse because it is opposite to the right angle. We will plug it into the pythagorean theorem.
a^2+b^2=c^2
9^2+7^2=c^2
81+49=c^2
130=c^2
