Calculate the

Answer:

Portion of walking in degrees = 72°

Step-by-step explanation:

The question is incomplete as the diagram is not shown in the question. I have attached the full question below. Consult it to understand the solution better

First calculate the percentage of walking from a total of all activities.

Percentage of walking = 10/50 · 100%

Percentage of walking = 20%

It means the portion of the circle(pie chart) for walking should be equal to 20% of the whole circle.

We know that the whole circle is equals to 360°

Circle = 360°

We need to calculate 20% of 360°, which will represent the portion of walking in degrees.

Portion of walking in degrees = 20/100 · 360°

Portion of walking in degrees = 72°

Which combination of integers can be used to generate the Pythagorean triple (5,12,13)

Kitty [74]

Answer:

x=3 and y=2

Step-by-step explanation:

The pythagorean triples are generated by two integrers x and y that can be found by solving the following system of equations:

$\left \{ {{x^{2}-y^{2}=5}\atop {2xy=12}} \atop {x^{2}+y^{2}=13}}\right.$

Solve the system of equations, and we get that the solution is x=3 and y=2.

Therefore, the combination of integrers that ca be used to generate the pythagorea triple are: x=3 and y=2
