20

Formula for perimeter: length x 2 + width x 2

70x2 is 140 then subtract it from 180 and you’ll get 40, then you half it and get 20

An estate of $686,000 is left to three siblings. The eldest receives 2 times as much as the youngest. The middle sibling receive

gregori [183]

Answer:

The oldest gets -> $335,500

The middle gets -> $182,750

The youngest gets -> $167,750

Step-by-step explanation:

Step 1: Make an equation

686,000 = 2y + (15,000 + y) + y

Step 2: Solve for y

686,000 - 15,000 = 2y + 15,000 + y + y - 15,000

671000 / 4 = 4y / 4

167,750 = y

Step 3: Figure the amount of money the middle sibling gets

m = y + 15,000

m = 167,750 + 15,000

m = 182,750

Step 4: Figure the amount of money the oldest sibling gets

o = 2y

o = 2(167,750)

o = 335,500

Answer: The oldest gets -> $335,500

The middle gets -> $182,750

The youngest gets -> $167,750

The table below describes the smoking habits of a group of asthma sufferers. If one of the 1156 people is randomly selected, fin

Rashid [163]

Answer:

0.554

Step-by-step explanation:

In the figure attached, the table is shown

Total people: 1156

Nonsmoker men + occasional smoker men + regular smoker men + heavy smoker men + heavy smoker women = men + heavy smoker women = 601 + 39 = 640

Probability that the person is a man or a heavy smoker = 640/1156 = 0.554

(Notice that if you directly add heavy smoker and total men you will count twice heavy smoker men)

The Thompson family is buying a car that can travel 70 miles on two gallons of gas. Assume that the distance traveled in miles y

artcher [175]

70/2 = 35

The car gets 35 miles per gallons.

You can also find that out by looking at the slope of the equation. y = 35x. 35 is the slope here.

For your graph, plot the points:
(0,0)
(1,35)
(2,70)
(3,105)
(4,140)
(5,175)
(6,210)
(7,245)
(8,280)

And then draw a line through the points.
