Answer:
2.915 × 10^9
Step-by-step explanation:
you count the from right to left since its a positive number until you get one number in front. That's where you place your decimal. Since there's 9 numbers behind the 2 it will be 10 to the power of 9.
$52.5
Explanation:
$10.50 × 5 = $52.5
The exact value of the cone is the answer corresponding with B
Answer: EP is 12 and EO is about 10.91.
To find the length of EP, we can use the Pythagorean Theorem with the 2 legs of the right triangle it would form, EC and CP. CP would be 5 because it is the midpoint of the side.
5^2 + (EP)^2 = 13^2
EP = 12
Now, to find EO, we write and solve another Pythagorean Theorem equation using 12 for EP.
5^2 + (EO)^2 = 12^2
EO equals the square root of 119 or about 10.91.
