Answer:
Musah's final point from the centre = 60.355 steps
Step-by-step explanation:
From the given information:
Musah stands at the centre of a rectangular field. He first takes 50 steps north, then 25 steps west and finally 50 steps on a bearing of 315°
The sketch for this information can be seen in the attached file below.
How far west is Musah's final point from the centre?
In order to determine how far west is Musah's,
Let d be the distance of how far;
Then d = QR + RS cos θ
In the North West direction,
cos θ = cos 45°
d = 25 + 50( cos 45°)
d = 25 + 50( 
)
d = 25 + 50( 0.7071)
d =25 + 35.355
d = 60.355 steps
Musah's final point from the centre = 60.355 steps

Here you go
Step-by-step explanation:
i just drew it/. you werent specific so this is it
We are given that this is an ideal gas, and that the volume and presumably the number of moles of gas are constant. We can use Gay-Lussac's Law, which describes volume and pressure. We have that pressure is directly proportional to volume. For a change in a gas, we can write the equation as
,
where i denotes initial and f denotes final.
We have that
,
, and
. We need to find
. To do so, let's first rearrange Gay-Lussac's equation to solve for
.
Now, we plug in our values to get
.
.
This seems like a reasonable value, because as temperature goes up, pressure goes up, and an increase in temperature corresponds to an increase in pressure.
Technically, you were given values with only one significant figure, so you can only report the value as
, but this depends on how your instructor usually does these problems!
Answer:
C.
Step-by-step explanation:
In total, Sophie needs $230.40.
Let's form an equation. 230.40 = 12.80x
You'll need to divide both sides by 12.80 to get the variable, x, by itself.
18 = x
Therefore the answer is C.
If 3/4 lb of bananas cost $0.90, then 1 lb of bananas cost $1.20.
