c)  22 points

d)  -11 points

Step-by-step explanation:

a)  20 * 3 = 60 points (all answered correct)

b)   0 point (Minimum score if you don't answer any of the questions)

c)  10 * 3 = 30 points

    (14 - 10)  * -2 = -8 points

d)  5 * 3 = 15 points

A fruit juice company makes two kinds of juice blends, each in 1 gallon bottles. the regular mix uses 1/2 a gallon of orange jui
Snowcat [4.5K]

Answer:

56 regular   37 tropical             Maximum profit   $204.75

Step-by-step explanation:

 Constraints are:  

r ≥ 0  

t ≥ 0  

2r+ 3t ≤ 125  

2r + 1t ≤ 150

I will multiply the second by -3 to cancel  t  variable and see what  is the maximum amount for the regular

2r + 3t ≤  225

-6r - 3t ≤   -450

ADD BOTH

-4r    ≤ -225

r≤ 56.5  

Since we need to pick whole bottles ,not a fraction of a bottle we need ro round down.It should be less  than 65.5.So we need 56 bottles of regular

2*56 +3t  ≤ 225

112+3t ≤ 225

3t ≤ 113

t≤  37.6666    

37 bottles of tropical

2*56 + 3*37 =  112+111 =223       223<225

2*56 +37  =  112 +37  =149          149<150

$2.5*56 = $140

$1.75*37 = $64.65

Total profit   $204.75

o-na [289]

9514 1404 393

Answer:

  (a)  64/25

Step-by-step explanation:

The relevant properties of exponents are ...

  a^0 = 1 . . . . a ≠ 0

  (a^b)^c = a^(bc)

  (ab)^c = (a^c)(b^c)

__

Your expression simplifies to ...

  \left(\dfrac{2^3\cdot3^0}{5}\right)^2=\dfrac{2^{3\cdot2}\cdot1^2}{5^2}=\dfrac{2^6}{5^2}=\boxed{\dfrac{64}{25}}

Describe and correct the error in writing an equation of the line with a slope of 2 and a y-intercept of 7.
olganol [36]

Answer:

The mistake they made was they switched the slope and y-intercept.

The correct answer is y=2x+7 because when we write an equation in slope intercept form (y=mx+b) you replace m with the slope and b with the y-intercept.

Hope this helps! <3
