Cone you need radius and height
Sphere you need radius

We can start with the basics. What we know is that this entire trip took 6 hours. So the travelers were able to walk on the level, uphill, and downhill in a total of 6 hours.

A level mile takes 1/4 of an hour (15 minutes). An uphill mile takes 1/3 of an hour (20 minutes). A downhill mile takes 1/6 of an hour (10 minutes). So, to go and return over the same mile takes half an hour. This means that in 6 hours, they went 12 miles and came 12 miles back. So they went a total of 24 hours.

If the 12 miles had been all level, it would have taken approximately 3 hours. It the 12 miles had been all uphill, it would have taken approximately 4 hours. When reaching the peak, 3.5 hours would have been the approximate time it took them to reach the top since it is in between. <span />

Please help anyone I’m so lost

The formula for the area of a triangle is A = 1/2 x b x height. But, we don't have the height here. To find the height, we can use the Pythagorean theorem.

With Pythagorean theorem, we'll be finding one of the legs. If we split the original triangle in 1/2 from the vertex to the base, we now have two right triangles. Both of these right triangles have a 30 cm hypotenuse and one 13 cm leg (remember we divided the entire original triangle in half).

30^2 = 13^2 + b^2

169 + b^2 = 900

b^2 = 731

b = $\sqrt{731}$

Now that we know the height of the triangle, we can find the area.

A = 1/2 x 26 x $\sqrt{731}$

A = 13 x $\sqrt{731}$

A = 351.48

The final area, rounded to the nearest whole number is 351 centimeters squared.

Note: Please know that depending on if the answer rounded $\sqrt{731}$ before using it to find the area, the final answer may then be rounded to 352.

Hope this helps! :)

Megan has $500 in short-term savings, $5,000 in her retirement savings account, $500 in credit card debt, and student loan debt

Given, the amount Megan has in short term savings = $500.

The amount in retirement savings account = $5000.

The amount in credit card debt = $500.

The amount in student loan debt = $6500.

So total assets of Megan = Sum of short term savings and retirement savings.

Total asset = $500 + $5000 = $ $(500+5000)$ = $ $5500$
