A train travels a total of 42 km at a constant speed of 85 km/h.
How long is its journey? Give your answer in minutes and seconds, to the nearest seconds
Answer:
formula is speed equals distance/ time.
now, speed above is 85km/h and distance is 42km.
time therefore is 42/85 which is 0.494h
now, 0.494h× 60 minutes is 29.64minutes(which is your answer in minutes)
now,29.64minutes × 60secs is 1778.82 seconds to the nearest seconds is 1779 seconds( which is your answer in seconds)

−9x+y=10 10x−y=−9 What is the resulting equation?
Answer:
x=1, y=19. (1, 19).
Step-by-step explanation:
-9x+y=10
10x-y=-9
--------------
x=1
10(1)-y=-9
10-y=-9
y=10-(-9)=10+9=19
Answer: I was kind of confused but here: x=3, y=21. if i am wrong try to be more elaborate and i will try to help
A city's population has increased 40% in the last 5 years and is now 53,782 people.
What was the population 5 years ago?
Given:
A city's population has increased 40% in the last 5 years and is now 53,782 people.
To find:
The population 5 years ago.
Solution:
Let x be the population 5 years ago.
A city's population has increased 40% in the last 5 years.
So, present population is
[tex]x+x\times \dfrac{40}{100}=x+0.4x=1.4x[/tex]
It is given that the present population is 53782.
[tex]1.4x=53782[/tex]
[tex]x=\dfrac{53782}{1.4}[/tex]
[tex]x=38415.7142857[/tex]
[tex]x\approx 38416[/tex]
Therefore, the population 5 years ago was about 38416.

Answer:
108
Step-by-step explanation:
I believe its 108 because the angle above it is alternate exterior angles with bmd so its 72. And we know that the angle across it must be congruent as well. Straight line adds up to 180 so 180-72 is 108
I need help with finding the answer to a) and b). Thank you!
Answer:
[tex]\displaystyle \sin\Big(\frac{x}{2}\Big) = \frac{7\sqrt{58} }{ 58 }[/tex]
[tex]\displaystyle \cos\Big(\frac{x}{2}\Big)=-\frac{3 \sqrt{58}}{58}[/tex]
[tex]\displaystyle \tan\Big(\frac{x}{2}\Big)=-\frac{7}{3}[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \sin(x)=-\frac{21}{29}[/tex]
Where x is in QIII.
First, recall that sine is the ratio of the opposite side to the hypotenuse. Therefore, the adjacent side is:
[tex]a=\sqrt{29^2-21^2}=20[/tex]
So, with respect to x, the opposite side is 21, the adjacent side is 20, and the hypotenuse is 29.
Since x is in QIII, sine is negative, cosine is negative, and tangent is also negative.
And if x is in QIII, this means that:
[tex]180<x<270[/tex]
So:
[tex]\displaystyle 90 < \frac{x}{2} < 135[/tex]
Thus, x/2 will be in QII, where sine is positive, cosine is negative, and tangent is negative.
1)
Recall that:
[tex]\displaystyle \sin\Big(\frac{x}{2}\Big)=\pm\sqrt{\frac{1 - \cos(x)}{2}}[/tex]
Since x/2 is in QII, this will be positive.
Using the above information, cos(x) is -20/29. Therefore:
[tex]\displaystyle \sin\Big(\frac{x}{2}\Big)=\sqrt{\frac{1 + 20/29}{2}[/tex]
Simplify:
[tex]\displaystyle \sin\Big(\frac{x}{2}\Big)=\sqrt{\frac{49/29}{2}}=\sqrt{\frac{49}{58}}=\frac{7}{\sqrt{58}}=\frac{7\sqrt{58}}{58}[/tex]
2)
Likewise:
[tex]\displaystyle \cos \Big( \frac{x}{2} \Big) =\pm \sqrt{ \frac{1+\cos(x)}{2} }[/tex]
Since x/2 is in QII, this will be negative.
Using the above information, cos(x) is -20/29. Therefore:
[tex]\displaystyle \cos \Big( \frac{x}{2} \Big) =-\sqrt{ \frac{1- 20/29}{2} }[/tex]
Simplify:
[tex]\displaystyle \cos\Big(\frac{x}{2}\Big)=-\sqrt{\frac{9/29}{2}}=-\sqrt{\frac{9}{58}}=-\frac{3}{\sqrt{58}}=-\frac{3\sqrt{58}}{58}[/tex]
3)
Finally:
[tex]\displaystyle \tan\Big(\frac{x}{2}\Big) = \frac{\sin(x/2)}{\cos(x/2)}[/tex]
Therefore:
[tex]\displaystyle \tan\Big(\frac{x}{2}\Big)=\frac{7\sqrt{58}/58}{-3\sqrt{58}/58}=-\frac{7}{3}[/tex]

The population of a small town was 10,800 in 2003. Since then, the population has
decreased at a rate of 2.5% each year. What is the population of the town in 2021?
Answer: 5940
Step-by-step explanation: I don't know if it's for sure right but here
First I knew 10,800 was 100% and I wanted to find 2.5%
So I did:
10,800 divided by 100 and I got 108 = 1%
Than you want to do
108 x 2.5 = 270 ( 2.5% )
After that you wanted to find out how much years apart so
2021 - 2003 = 18
Then
18 x 270 = 4,860
Last of all you have to do
10,800 - 4,860 = 5940

Z is the centroid of A MVI. if MZ= 30, find ZR
Answer:
ZR = 15
Step-by-step explanation:
Centroid of a triangle is a point inside the triangle where all medians meet.
And centroid divides the medians in the ratio of 2:1
By this property,
ZM : ZR = 2 : 1
ZM = 30 [Given]
Let the measure of median MR = a units
Therefore, ZM = [tex](\frac{2}{2+1})(MR)[/tex]
30 = [tex]\frac{2}{3}(a)[/tex]
a = 45 units
Now, ZR = [tex](\frac{1}{2+1})(MR)[/tex]
ZR = [tex](\frac{1}{3})(45)[/tex]
ZR = 15
