Add 1 to both sides
13=-9y
13/-9 = -1.4 repeated or -1 4/9
1 mile is 5280 feet, therefore, we have 60 miles, and each mile is 5280 feet, so we multiply 5280 and 60, you get the answer of 316,800 feet.

A) Diagram
Below is a sketch of the recctangular lawn (the inside rectangle) and the gravel border.
6 ft + 150 yards + 6 ft

B) How many square feet of the gravel will surround the lawn?
Conversion: 1 yard = 3 feet
=> 80 yard = 80*3 feet = 240 feet
=> 150 yard = 150 * 3 feet = 450 feet
Area of the external rectangle = (6 ft + 240 ft + 6 ft) (6 ft + 450 ft + 6 ft) = 252 ft * 462 ft = 116,424 ft^2
Area of the internal rectangle = 240 ft * 450 ft = 108,000 ft^2
Area of the gravel border = 116,424 ft^2 - 108,000 ft^2 = 8424 ft^2
answer: 8424 ft^2
C) volume
volume = area of the base * depth
2 inches = 2/12 ft = 1/6 ft
=> volume = 8424 ft^2 * 1/6 ft = 1404 ft^3
answer: 1404 ft^3
C) cost
1 yard^3 = $ 30
1yard ^3 = (3 feet)^3 = 27 ft^3
=> cost = $ 30 / 27 ft^3
=> 1404 ft^3 * $30 / 27 ft^3 = $ 1560
answer: $ 1560
Answer:
1/16
Step-by-step explanation:
There is a 50% chance of it being a boy or a girl also known as 1/2
So the first baby has a 1/2 chance, same for the second, and third, Which means that there is a 1/2, then another 1/2 and another 1/2. So you would have to multiply them all, 1/2*1/2*1/2 = 1/8. For the girl, again, it is 1/2 chance of being a girl, while the other 1/2 is a boy. So 1/8*1/2 is 1/16. So the probability so the women having 3 boys then a girl, is 1/16.
Hope this helps
