AlladinOne [14]

Answer:

G(x) =0.4/0.7

F(x)= 6.6/14

Step-by-step explanation:

G(x)= 0.4/0.7

F(x)= 4(0.4)+5

=6.6

4(0.7)+5

=14.

Nady [450]

Answer:

Total money he had left=629.85

Step-by-step explanation:

We can express Phil's earnings from pizza sales as;

Total earnings from pizza sales=(price per slice×number of pizza slices sold)+(price per whole pizza×number of whole pizzas sold)

where;

Price per slice of pizza=1.75

Number of pizza slices sold=76 slices

Price per whole pizza=9.50 whole pizzas

Number of whole pizzas sold=64

Replacing in the expression above;

Total earnings from pizza sales=(1.75×76)+(9.5×64)=741

Total money he had left=Total earnings from pizza sales-15% of Total earnings

where;

Total earnings from pizzas ales=741

15% of Total earnings=(15/100)×741=111.15

Replacing;

Total money he had left=(741-111.15)=629.85

Talja [164]

Answer:

the number of possibilities that can be drace himself up for the day is 216

Step-by-step explanation:

Given that

jun has 12 t-shirts,6 pairs of pants and 3 pairs of shoes

We need to find out the possibilities that can be drace himself up for the day

So here

$= 12C_1 \times 6C_1 \times 3C_1\\\\= \frac{12!}{1!(12 - 1)!} \times \frac{6!}{1!(6 - 1)!} \times \frac{3!}{1!(3 - 1)!}\\\\= \frac{12!}{1!(11)!} \times \frac{6!}{1!(5)!} \times \frac{3!}{1!(2)!}\\\\= 12 \times 6 \times 3\\\\= 216$

Hence, the number of possibilities that can be drace himself up for the day is 216

The same would be considered and relevant too

Hailey's mixing two different coffee blends. Represent them by x and y (in pounds). Then x + y = 5 lb, and x = 5 - y.How much puree Sum. beans are we talking about here?
0.20x +0.80y = 0.60(5 lb) Mult all 3 terms by 100 to get rid of factions:
20x + 80 y = 300. Substitute 5-y for x:
20(5-y) + 80y = 300 => 100-20y + 80y = 300 => 60y = 200, so y = 20/6 or 10/3 lb den x = 5-10/3, or x =5/3 lb
Use 5/3 lb of the first blend and 10/3 lb of the second blend to come up with 5 lb of a 60% blend.
