Woodland Bicycles makes two models of off-road bicycles: the Explorer, which sells for $250, and the Grande Expedition, which se
elena-s [515]

Answer:


Step-by-step explanation:

Let X be number of woodland bicyles and Y grande expedition

Our objective is to maximize profit

Z = 250x+350Y

Constraints are:  2x+3y<450 and

x+y<375

(given)

Solution gives negative y. Hence intersecting point is not within constraint.

So choices satisfying the constraints would be min of 225, 375 for x and min of 150,375 for x

i.e x=225 and y =150

To maximize revenue 225 Woodland and 150 Grande to be produced

6n+7-2n-14=5n+1 asap pls
polet [3.4K]
First, combine like terms to get 4n-7=5n+1

add 7 to both sides to get 4n=5n+8

subtract 5n from both sides to get -n=8

multiply both sides by -1 to get an answer of n=-8

In the last 10 years, the population of Indonesia has grown at a rate of 1.12% per year to 258,316,051. If this rate continues,
Reptile [31]

Answer:

Final population after 10 years

= 288911718

Step-by-step explanation:

Present population p = 258,316,051

Rate of growth R%= 1.12%

Number of years t= 10 years

Number of times calculated n = 10

Final population A

= P(1+r/n)^(nt)

A= 258,316,051(1+0.0112/10)^(10*10)

A= 258,316,051(1+0.00112)^(100)

A= 258,316,051(1.00112)^100

A= 258,316,051(1.118442762)

A= 288911717.6

Approximately A= 288911718

Final population after 10 years

= 288911718

Help please, need help
iren2701 [21]

Answer:

Step-by-step explanation:

B) Small triangle:

height = 20 - 15 = 5

base = 1

height to base =  5 :1

Medium triangle :

height = 60 -30 = 30

base = 2

height to base =  30 :2  = 15 :1

Large triangle:

height = 120 - 60 = 60

base = 4

height to base =  60 : 4 = 15 : 1

c) The ratios are same. This is true because wage and working hours are in direct proportion.

E) Take any two points. (1 , 15) & (2 , 30). Find the slope.

Slope = Change in y ÷ change in x

 m = (30-15) ÷ (2 -1) = 15/1 = 15

y -y1 = m(x -x1)

y - 15 = 15(x - 1)

y - 15 = 15x - 15

y = 15x - 15 + 15

y = 15x
