Answer:
V = -9
Step-by-step explanation:
-15V - 40 = 23 - 8V
The objective is to get V alone. To do this, first subtract -15V from both sides. Since -15V is a negative, subtracting it will be adding a positive.
-40 = 23 + 7V
Now that there is only one term with the variable V, subtract 23 from both sides.
-63 = 7V
Finally, divide both sides by 7 to get V completely isolated.
-9 = V.
The final answer is V = -9.
The correct answer is B
325-45=280
8x35=280
The second one is the correct answer. Plug in -3 into the equation.
The maximum possible measurement is 1.25 Kg
and the minimum possible measurement is 1.15 kg
<u>Solution:</u>
Given mass of an ostrich egg is 1.2 Kg
We have to find the minimum and maximum possible measurements to the nearest tenth of a kilogram
The greatest possible error in measurement nearest tenth of a kilogram, is a half a tenth of a kilogram which is:-

Now, the maximum value will be equal to calculated amount plus the error in measurement of value .i.e.

Now, the minimum value will be equal to calculated amount minus the error in measurement of value .i.e.

Hence, maximum possible measurement is 1.25 Kg
And the minimum possible measurement is 1.15 kg
The height of the chimney above the floor of the observation deck is 52.4 ft
Two right angle triangle will be formed.
<h3>Right angle triangle:</h3>
Right angle triangle are triangle that has one of its angle as 90 degrees.
Therefore, using trigonometric ratio,
adjacent side = distance of observer from the bottom edge of the Delaware River drawbridge observation deck
Therefore,
tan 40 = opposite / adjacent
Where
x = height of the observer to the top of the observation deck
tan 40 = x / 200
x = 200 tan 40
x = 167.819926235
x = 167.82 ft
tan 30 = opposite / adjacent
y = height of the observer to the bottom of the observation deck
tan 30 = y / 200
y = 200 tan 30
y = 115.470053838
y = 115.47 ft
The height of the chimney above the floor of the observation deck = height of the observer to the top of the observation deck - height of the observer to the bottom of the observation deck
The height of the chimney above the floor of the observation deck = 167.82 - 115.47 = 52.35 ft
