Jim is 4 years older than mark if the sum of their ages is 44 find the age of each person
Nataliya [291]

Answer:

jim is 24 years old,  Mark is 20 years old

Step-by-step explanation:

This prompt can be set up using this equation:

Let's represent Mark's age by variable m and Jim's age by variable J.

j + m = 44

m + 4 = j

m = j - 4

j + (j - 4) = 44

2j - 4 = 44

2j = 48

j = 24

So, jim is 24 years old, meaning mark must be 20 years old. 20 + 24 results in 44 years old together.

Island A is 150 miles from Island B. A ship captain travels 310 miles from Island A and then finds that he is off course and 200
wolverine [178]

Answer:

156.37°

Step-by-step explanation:

We solve this above question, using Cosine rule which is given as:

Cos C = a² + b² - c²/2ab

Let the Angle be represented as: x

Cos x = 310² + 200² - 150²/2 × 310 × 200

x = arc cos [ 310² + 200² - 150²/2 × 310 × 200]

x = 23.63°

The angle, in degrees, that he must turn through to head straight for Island B is given as:

180° - 23.63°

= 156.37°

Find the value of x in the triangle shown below. x = 56° 99°​
anyanavicka [17]

Answer:

x = 25 degrees

Step-by-step explanation:

All angles in a triangle should add up to 180 degrees. So to solve for x, set up an equation where all three angles added up equals 180.

180 = 99 + 56 + x

180 = 155 + x

25 = x

The unknown angle is equal to 25 degrees.

Which fraction is equivalent to 2/5?  <br> A. 4/10 <br> B. 2/10   <br> C. 1/2   <br> D. 4/6
Lelechka [254]
Hey there James!

So, just remember, 2/5 is almost half of 1.

When it is almost half of 1, this means that it would have to be 2.5/5

This would mean that 4/10 would be your answer, because it is almost half of 1 also.

Hope this helps.
