Let
x-------> the width of the rectangular area
y------> the length of the rectangular area

we know that
y=x+15------> equation 1
perimeter of a rectangle=2*[x+y]
2x+2y <= 150-------> equation 2

substitute 1 in 2
2x+2*[x+15] <=150--------> 2x+2x+30 <=150----> 4x <=150-30
4x <= 120---------> x <= 30
the width of the rectangular area is at most 30 ft
y=x+15
for x=30
y=30+15------> y=45
the length of the rectangular area is at most 45 ft

see the attached figure

Find the value of X.

ch4aika [34]

Answer:

x= 60

Step-by-step explanation:

if y is the other missing side

y^2 = 64^2 + 48^2

y^2 = 4,096 + 2,304

y^2 = 6,400

100^2 = x^2 +y^2

x^2 = 10,000 - 6,400

x^2 = 3,600

x = 60

A certain portfolio consisted of 5 stocks, priced at $20, $35, $40, $45, and $70, respectively. On a given day, the price of one

saveliy_v [14]

Answer:

Option E: 35, 40, 45

Step-by-step explanation:

To solve this problem we can test the options, checking if the calculations will match the result.

A.

20, 35 and 70 remained constant.

The average price of a stoc in the portfolio before the changings were:

(20+35+40+45+70)/5 = 42

With an increase of approximately 2%, the average value will be approximately 42*1.02 = 42.84

If the average price of a stock in the portfolio rose, and the rise of one stock in percentage was bigger than the fall of the other stock, we need to choose the stock that has the bigger price as the one that increased its value.

An increase of 15% is calculated multiplying the base value by 1.15, and a decrease of 35% is calculated multiplying the base value by (1-0.35)=0.65.

So, if the stocks affected were the $40 and 45$, we have that:

(20+35+40*0.65+45*1.15+70)/5 = 40.55

That's not the correct answer.

B.

20, 45 and 70 remained constant.

Affected: 35 and 40

(20+35*0.65+40+45*1.15+70)/5 = 40.9

That's not the correct answer.

C.

20, 35 and 40 remained constant.

Affected: 45 and 70

(20+35+40+45*0.65+70*1.15)/5 = 40.95

That's not the correct answer.

D.

35, 40 and 70 remained constant.

Affected: 20 and 45

(20*0.65+35+40+45*1.15+70)/5 = 41.95

That's not the correct answer.

E.

35, 40 and 45 remained constant.

Affected: 20 and 70

(20*0.65+35+40+45+70*1.15)/5 = 42.7

That's the correct answer, with an increase in the average value of 0.7/42 = 0.0167 = 1.67%
