Chick-fil-A offers its customers a choice of regular and diet soda. Last night, Chick-fil-A served 50 sodas in all, 27 of which

soldier1979 [14.2K]

Answer:

54%

Step-by-step explanation:

We know Chick-fil-A served 50 sodas in all, 27 of which were regular. The fractional form of this is 27/50. Now, we can convert this to a fraction with a denominator with 100, then a percentage. 27/50 is equal to 54/100.

54/100 is 54%

Please help! find QPR

aleksley [76]

Answer:

m∡QPR = 25°

Step-by-step explanation:

solve for 'x':

8x + 7 + 9x + 16 = 40

17x + 23 = 40

17x = 17

x = 1

m∡QPR = 9(1) + 16

m∡QPR = 25°

What is 2x-3 I have no idea what it is

cricket20 [7]

Answer:

Step-by-step explanation:

2x - 3 is a linear expression. y = 2x - 3 is the equation describing y.

If x = 1, y = 2(1) - 3 = -1

If x = 2, y = 2(2) - 3 = 1

and so on.

Isn't there more to this problem that merely "2x - 3"?

Find the maximum and minimum values of the function f(x,y)=2x2+3y2−4x−5 on the domain x2+y2≤100. The maximum value of f(x,y) is:

ryzh [129]

First find the critical points of f :

$f(x,y)=2x^2+3y^2-4x-5=2(x-1)^2+3y^2-7$

$\dfrac{\partial f}{\partial x}=2(x-1)=0\implies x=1$

$\dfrac{\partial f}{\partial y}=6y=0\implies y=0$

so the point (1, 0) is the only critical point, at which we have

$f(1,0)=-7$

Next check for critical points along the boundary, which can be found by converting to polar coordinates:

$f(x,y)=f(10\cos t,10\sin t)=g(t)=295-40\cos t-100\cos^2t$

Find the critical points of g :

$\dfrac{\mathrm dg}{\mathrm dt}=40\sin t+200\sin t\cos t=40\sin t(1+5\cos t)=0$

$\implies\sin t=0\text{ OR }1+5\cos t=0$

$\implies t=n\pi\text{ OR }t=\cos^{-1}\left(-\dfrac15\right)+2n\pi\text{ OR }t=-\cos^{-1}\left(-\dfrac15\right)+2n\pi$

where n is any integer. We get 4 critical points in the interval [0, 2π) at

$t=0\implies f(10,0)=155$

$t=\cos^{-1}\left(-\dfrac15\right)\implies f(-2,4\sqrt6)=299$

$t=\pi\implies f(-10,0)=235$

$t=2\pi-\cos^{-1}\left(-\dfrac15\right)\implies f(-2,-4\sqrt6)=299$

So f has a minimum of -7 and a maximum of 299.

Paladinen [302]

1. 18
2. 33
3. 28

explain: division first so 6x3
multiply first so 12+21
multiply both then add so 12+16
