Step-by-step explanation:
Remark
Notice you are working with minus signs. You final answer must be "smaller" than what you started out with. In other words, your final answer must be more negative.
Givens
Beginning level below sea level = -1260 feet
rate of descent = 5 feet per minute
Number of minutes = 12 minutes
Equation
Final level = initial level - rate * time Substitute givens into equation.
Solution
Final Level = - 1260 - 5*12
Final Level = - 1260 - 60
Final level = - 1329
Answer: - 1320 feet
Answer: The scale is 5cm/m (5 cm in the drawing are equivalent to 1 meter on the actual pit)
Step-by-step explanation:
When we have an original measure M, and we redraw it with a new scale, where the new measure is m, the scale used is equal to:
scale = m/M.
In this case, we know that:
The pit is 3m, by 5m
and the drawing to scale is 15cm by 25cm
(15cm is the rescaled version of the 3m side, and 25cm is the rescaled version of the 5m side)
Using the equation above, we can find that the scale is:
Scale = 15cm/3m = 5cm/m
and, if we use the other side, we get:
Scale = 25cm/5m = 5cm/m
Both calculations give the same scale, as expected.
Then the scale is 5cm/m, which means that 5 centimeters in the drawing are equivalent to one meter in the real pit.
Answer:
The five dots above the number three represent the number of <u><em>students</em></u> that have three E-Mail accounts. The number of students that have three accounts is five.
Answer:
x = 10.5 in
Step-by-step explanation:
The rectangles are similar, thus the ratios of corresponding sides are equal.
that is = ( cross- multiply )
2x = 21 ( divide both sides by 2 )
x = 10.5
Round to the nearest significant number
275,000,000 = 2.75^8
2.75^8 is your answer
hope this helps
