What’s the equation of the circle with center (9, –1) and radius r = 7?

avanturin [10]

$\bf \textit{equation of a circle}\\\\ 
(x- h)^2+(y- k)^2= r^2
\qquad 
center~~(\stackrel{9}{ h},\stackrel{-1}{ k})\qquad \qquad 
radius=\stackrel{7}{ r}
\\\\\\\
[x-9]^2+[y-(-1)]^2=7^2\implies (x-9)^2+(y+1)^2=49$

At the time this question was written, one US Dollar equaled 0.88 Euros. What would 50 Euros equal in US Dollars? Round your ans

KengaRu [80]

Answer:

$56.82 US dollars

Step-by-step explanation:

Set up a proportion where x is how many US dollars there are in 50 Euros:

$\frac{1}{0.88}$ = $\frac{x}{50}$

Cross multiply and solve for x:

0.88x = 50

x = 56.82

So, 50 Euros is approximately equal to $56.82 US dollars

Find two numbers given that their sum is 60 and

likoan [24]

Answer:

12 and 48

Step-by-step explanation:

let n be the larger number , then $\frac{1}{4}$ n is the smaller number and their sum is

x + $\frac{1}{4}$ x = 60 ( multiply through by 4 to clear the fraction )

4x + x = 240 , that is

5x = 240 ( divide both sides by 5 )

x = 48

smaller number = $\frac{1}{4}$ × 48 = 12

The 2 numbers are 12 and 48
