Answer:
b = 6
Step-by-step explanation:
You probably already know the general equation from the my last couple of answer.
In this question, we have:
a=8
b= ?
c= -10 , c is the value of the foci
surprisingly, you can solve the value for a, b, and c using the same equation as the Pythagorean theorem.
c² = a² + b²
we need to solve for b so lets rearrange the equation.
b² = c² - a²
b = ±√(c² - a²)
b = ±√((-10)² - (8)²)
b = ±√((-10)² - (8)²)
b = ±√(100 - 64)
b = ±√(36)
b = ±6
b = 6
37.5 pounds if you multiply 45x14 which equals 630 and then 6x20 which equals 120 add it together to get 750 and then divide by the total number of dogs, 20 to get the average weight.
Answer:
x=-b/2a
Step-by-step explanation:
Answer: You could add the strings together to get 22 inches.
For a diagram of this simply draw two line segments that are right next to each other.
You could measure and label the smaller one with 7 units and the larger one with 15 units. Then, anyone could just count to 22 to find the total.
90/17
You would take 45/8.5, but that’s an improper fraction so you’d multiply top and bottom by two, resulting in 90/17. As far as I know, that fraction will not simplify down further. You could write it as a whole number with a fraction— 5 and 5/17 but I’d assume that’s not what they’re looking for
