Answer: 64cm

Step-by-step explanation:

length=3w\\width=w\\area=192cm^2\\perimeter=?

First, using the area formula, find length and width;

A=l*w

192=3w*w

192=3w^2

Divide by 3.

\frac{192}{3}=w^2

64=w^2

Extract the square root.

\sqrt{64}=w\\ 8=w

Now that you found the width; find length.

if length is three times width; multiply the width by 3.

8*3=24cm

Now that you have all the information, find the perimeter.

P=2(l+w)\\P=2(24+8)\\P=2(32)\\P=64cm

Answer:

x: length

y: wide

x = 3y and x*y =192

=> 3y^2 = 192

=> y = 8 => x =3x8 = 24

=> Perimeter = (x+y)*2 = (8+24)*2 = 64

Find the maxium valve C=6x+2y. Subject to the following constraints x≥0, x≤5, y≥0, 4x-y≥1
Vadim26 [7]

Answer:

The maximum value of C is 68

Step-by-step explanation:

we have the following constraints

x\geq 0 ----> constraint A

x\leq 5 ----> constraint B

y\geq 0 ----> constraint C

4x-y\geq 1 ----> constraint D

Find out the area of the feasible region, using a graphing tool

The vertices of the feasible region are

(0,0),(5,19),(5,0)

see the attached figure

To find out the maximum value of the objective function C, substitute the value of x and the value of y of each vertex in the objective function and then compare the results

C=6x+2y

For (0,0) -----> C=6(0)+2(0)=0

For (5,19) -----> C=6(5)+2(19)=68

For (5,0) -----> C=6(5)+2(0)=30

therefore

The maximum value of C is 68

In a large population, 57 % of the people have been vaccinated. If 3 people are randomly selected, what is the probability that
ollegr [7]

Answer:0.92

Step-by-step explanation:

Given

57\% of Population is vaccinated

So, Probability of a person being vaccinated is P=0.57

and simultaneously , probability of not vaccinated is 1-P

=1-0.57=0.43

Now, Probability that atleast one of them has been vaccinated is given by

=1-P(\text{None of them is vaccinated})

=1-0.43\times 0.43\times 0.43

=1-0.0795

=0.92

The larger of two numbers is one more than 3 times the smaller. Eight times the smaller decreased by
Zina [86]
L# = 1 + 3S#
8S# - 2L# = 10

8S# - 2(1 + 3S#) = 10
8S# - 2 + 6S# = 10
14S# = 12
S# = 6/7

L# = 1 + 3(12/14)
L# = 25/7
