Answer:
(x - 3)² + (y + 4)² = 90 or [3√10)²
Step-by-step explanation:
We need to calculate the radius of this circle. To do this we calculate the distance from the center (3, -4) to the point (6, 5).
As we move from (3, -4) to (6, 5), x (the run) increases by 3 and y (the run) increases by 9. Thus, the distance between these points, according to the Pythagorean Theorem, is
r = √[3² + 9²], or r = √90, or r = 3√10.
Using the standard equation of the circle, (x - h)² + (y - k)² = r², we obtain
(x - 3)² + (y + 4)² = 90 or [3√10)²
Answer:
5 is the correct answer
Step-by-step explanation:
20 divide by 100 because it is in percent and 20 miltiply by 100 and there is the sign of multiply (of) is also known as multiply soo 20\100 * 25 will be the answer 5
Hi there,
So the problem is 2/7 ÷ 1/3
well the answer to this is 6/7
In order to solve this is to cross multiply so
2 x 3 and 7x3
which is the result of 6/7
In decimal form it is: 0.857
Hope this is correct :)
Have a great day

Step-by-step explanation:
Answer:
if Suzanne goal was to collect 600+ dollars in 16 weeks than she did achieve it
Step-by-step explanation:
I am not sure what the goal of this mathematical problem is but if you need a specific number of money to be collected multiply the by the number of weeks.
4 weeks ( 4*7)=28
160/28=5.71428571429
5.71428571429-(money per week saved by Suzanne)
if Suzanne continue continue with her saving for the next 12 months she will have a grand total of:
12+4= 16 ( total weeks)
7*16=112
112 * 5.71428571429 = 640
