<u>Answer:</u>
○ 
<u>Step-by-step explanation:</u>
We know that:
,
where F is the length of the foot of a person, and S is their shoe size.
To solve for the length of a person's foot, we have to rearrange the given equation to make F the subject:
⇒ 
[adding 24 to both sides]
⇒ 
[dividing both sides by3]
⇒ [swapping the sides]
Answer:
City 1 and City 2
Step-by-step explanation:
The water is moving down stream, moving from City 1-2-3-4 in that order.
if water was taken a the X mark, the pollutants would have to have come from the cities above where the sample was taken.
Hope this helps!
Answer:
a) 3.507
b) 75.48
c) 78.41
Step-by-step explanation:
Problem A
The opposite side of the angle and the hypotenuse are involved in the question. Therefore you will be using the sine.
sin(26) = x / 8 Multiply both sides by 8
8*sin(26) = x Sin(26) = 0.4384
8*0.4384 = x Do the multiplication
3.507 = x
Problem B
The side adjacent and the hypotenuse are used in this problem. The angle is given, so you are working with the cosine.
Cos(58) = adjacent / hypotenuse
Cos(58) = 0.5299
0.5299 = 40/x Multiply both sides by x
0.5299 x = 40 Divide both sides by 0.5299
x = 40 / 0.5299
x = 75.48
Problem C
The opposite side and the adjacent side are involved and the angle is given.
Tan(71) = opposite / adjacent
tan(71) = 2.904
2.904 = x / 27 Multiply both sides by 27
2.904 * 27 = x Combine
x = 78.414
Y-axis, because what i’ve been taught with coordinates, is you crawl before you walk which means is first it’s x-axis then y-axis. so (0,4) would be on the y-axis. :)
72 minutes. First convert the height of the pool to inches by multiplying the height in feet by 12 which equals 36. Next multiply that by 2 because the pool is draining at -1/2 inches per minute, not -1 inch per minute.
