DochEvi [55]

Answer:

we predict 2,587 persons will adopt dogs

Step-by-step explanation:

out of 40 persons 23 adopt dogs

Then

out of 40×25 persons 23×25 adopt dogs

Then

out of 1000 persons 575 adopt dogs

Then

out of 1000×4.5persons 575×4.5 adopt dogs

Then

out of 4,500 persons 2,587.5 adopt dogs

Method 2 :

Let x Ben the number of persons we predict they will adopt dogs:

Here we have a proportional relationship:

Then

$\frac{4500}{40} =\frac{x}{23}$

$\Longleftrightarrow x = \frac{4500\times 23}{40} =2587.5$

22.Island A is 160 miles from island B. A ship captain travels 170 miles from island A and then finds that he is off course and

bixtya [17]

we know that

Applying the law of cosines:

c² = a² + b² - 2abcos(C)

where:

a,b and c are sides of the triangle and C is the angle opposite side c

let

a=170 mi

b=200 mi

c=160 mi

that is

160² = 170² + 200² - 2(170)(200)cos(C)

solve for C

25,600 = 28,900 + 40,000 - 68,000cos(C)

25,600 - 28,900 - 40,000 = -68,000cos(C)

-43,300=-68,000cos (C)

cos (C)=0.6367

C=arc cos(0.6367)--------> C=50.45°

hence,

he should turn in the direction of island b by

180 - 50.45 = 129.55 degrees

the answer is

129.55 degrees

B) B

Step-by-step explanation:

2 times 4 is 8, so in this case the option is option b as none of the other options show this.

In total,

2 * 4 = 8

60 * 4 = 240

240 + 8 = 248
