Answer:

n - m

Step-by-step explanation:

It will be written as n - m. Only 1 sign in the middle is needed to be written.

m - - n = m + n

m - + n = m - n

For Tran thank you appreciate it
Anestetic [448]

Step-by-step explanation:

Let alpha be the unknown angle. We can set up our sine law as follows:

\frac{ \sin( \alpha ) }{5 \: m}  =  \frac{ \sin(42) }{3.6 \: m }

or

\sin( \alpha )  =  \frac{5 \: m}{3.6 \: m} \times  \sin(42)  = 0.929

Solving for alpha,

\alpha  = arcsin(0.929) = 68 \: degrees

4m/5-2m/3=1 solve the equation
katen-ka-za [31]

Answer:

m = 7.5

Step-by-step explanation:

4m/5   - 2m/3  =1

We want to get rid of the fractions so multiply each side by 5*3 or 15

15 *(4m/5   - 2m/3 ) =1*15

15 *(4m/5)   -15( 2m/3 ) =1*15

Canceling like factors

3* 4m -5*2m = 15

Multiply

12m - 10m = 15

2m = 15

Divide each side by 2

2m/2 = 15/2

m = 7.5

Question 13
ArbitrLikvidat [17]

Answer:

C

Step-by-step explanation:

Here in this question , we are interested in calculating the total distance covered by the train in the 10 minutes that it ran.

From the first part of the question, we already know the distances in the first 5 minutes.

Now, to calculate the total distance in the second 5 minutes, we use the distance formula since we have the average speed and the time;

Mathematically; Total distance = average speed * time

From the question, average speed is 33km/h, while time is 5 minutes. To achieve a consistent unit, we convert 5 minutes to hours.

That would be 5/60 = 1/12 hours

So the total distance in the second 5 minutes is;

33 * 1/12 = 2.75 km

Now, to calculate the total distance traveled, let’s add up the distances in the first 5 minutes and convert to kilometers;

That would be;

68 + 127 + 208 + 312 + 535 = 1,250 m

Let’s convert this to km.

We simply divide by 1000 = 1250/1000 = 1.25 km

The total distance is thus ;

1.25 + 2.75 = 4 km
