8 pm to midnight (12 pm) = 4 hrs
so the temp dropped -16.8 in 4 hrs (because the temp started at 0)
-16.8/4 = -4.2....so it dropped 4.2 every hr.
temp at 9 pm (1 hr after 8) would be (0 - 4.2) = -4.2
You need to multiple both fractions so that they share a common denominator. In this case, it's 60.
7/12= 35/60
1/5= 12/60
You can see that they are not equal, and that 7/12 is greater than 1/5 :)
So a diver went 25.65 ft BELOW so it's negative.
then he went 16.5 ft further down, so that's negative also.
he then rose 12.45 ft, so that's positive.
so the expression is: -25.65+-16.5+12.45, the answer is 23.7
Answer:
i think it would be 5,000 but im not for sure
Step-by-step explanation:
Answer: Area = 28.2m²
Step-by-step explanation: The triangle YXZ is shown in the figure below.
Area of a triangle is calculated by the formula:
According to the figure, the base of this triangle is b = 8.3m.
Height is a perpendicular line created from one side and intersecting the opposite angle.
To determine the height, use trigonometric relations to angle 68:
h = 7.3*sin(68)
h = 7.3*0.93
h = 6.8
Now, area of triangle YXZ is
A = 28.2
Area of triangle YXZ is 28.2m².
