Answer:

B) 12

Step-by-step explanation:

Hope the measure are the sides of right triangle.

Here c is the hypotenuse.

According to the Pythagorean theorem.

a^2 + b^2 = c^2

Now plug in a =16 and c = 20, we get

16^2 + b^2 = 20^2

256 + b^2 = 400

b^2 = 400 - 256

b^2 = 144

Taking square root on both sides, we get

b = √144

b = 12

Hope this will helpful.

Using the Pythagorean Theorem:

a^2 + b^2 = c^2

16^2 + b^2 = 20^2

256 + b^2 = 400

b^2 = 400 - 256

b^2 = 144

b = √144

b = 12

Two equations are given below: a – 3b = 22 a = b – 2 What is the solution to the set of equations in the form (a, b)? (–10, –8)
aliya0001 [1]
Hi Kristian

a - 3b = 22
a = b - 2

We need to solve a = b -2 for a
First, we need to substitute b - 2 for a in a - 3b = 22
a - 3b = 22
b - 2 - 3b = 22
-2b - 2 = 22
 -2b = 22 + 2
-2b = 24
b = 24/-2
b = -12

Now substitute -12 for b in a = b - 2
a = b -2
a= -12 - 2
a= -14

Thus, the solution is a = -14 and b = -12

The correct option is the last one (-14,-12)


If you have questions about my answer, please let me know.


Good luck!

Han can run 100 meters in 20 seconds how long will it take him to run 3000 metres
Juliette [100K]

Answer:

600 seconds

Step-by-step explanation:

In this case we have to calculate the speed;

Speed = Distance/Time

Speed = 100/20 = 5 mph

Next to get our answer we have to calculate the amount of time

Time = Distance/Speed

Time = 3000/5 = 600 seconds
