Answer:

122 1/4

Step-by-step explanation:

Hope this helps! :)

(12x12) 12x \frac{2}{3\\} x12) / (3/2 x3/2)

PEMDAS = parathesis exponents multiplictation division add subtract.

12x12=24

3/2x3/2=9/4

12x2/3=8x12=96

so 24+96=120

9/4 can be like 4x2=8 so i remaing

120+2=122 1/4?

6. Kiera is comparing the cost of two swimming pool memberships to determine which she will buy. Pool K charges a $30 membership
balandron [24]

Answer:

Pool K cost equation : 30 + 5V , Pool M cost equation : 10 + 10V

Pool K slope & intercept  = 30 & 5 , Pool M slope & intercept = 10 & 10

Step-by-step explanation:

Total cost  [Pool] = Fixed (membership) cost + Variable cost (per visit)

<u>Intercept</u> is part at which equation line intersects x or y axis. In pools case, it is  fixed (membership) cost. <u>Slope </u> is change in y due to change in x. In pools case, it is variable cost (per visit)

Pool K cost equation : 30 + 5V , Pool M cost equation : 10 + 10V

where V = number of visits.

Pool K slope & intercept  = 30 & 5 , Pool M slope & intercept = 10 & 10

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

a shopkeeper had 60 kg apples with him in the morning of a particular day during the day time he could sell only 43 kg 700 gram.
yan [13]
He has 16 kg 300 grams of apples left with him.

Explanation:
60 kg = 60 x 1000 = 60000 grams
43 kg 700 grams = 43700 grams

Left = 60000 - 43700 = 16300 grams = 16 kg 300 grams
