the formula for the lateral area of a right cone is la = πrs, where r is the radius of the base and s is the slant height of the cone.

which are equivalent equations? check all that apply.

a. s = la/πr
b. s = πr/la
c. s = laπr
d. r = la/πs
e. r = laπs

The two correct answers are A and E. You can immediately eliminate C and E because to bring over something that is multiplied you have to divide (fraction). And B isn't the answer because to isolate s you divide by πr which would bring πr to the denominator, not the numerator.
Hope this helps!

Option A and D are correct.        

Step-by-step explanation:

Given the formula for the lateral area of a right cone is

LA = πrs

where r is the radius of the base and s is the slant height of the cone.

we have to select the equations which equivalent to the above

we have to solve the given equation for variable s and r.

Solve for s

Solve for r

Option A and D are correct.

The total length (in units) of the biking trail is:

                          10 units.

Step-by-step explanation:

We know that the distance between two points A(a,b) and B(a',b') is calculated by using the distance formula:

It is given that:

The trail starts at P(−2, 2) and goes to Q(5, 2).

This means that the distance traveled in this trail is:

and

The other trail goes from Q to R(5, −5) and then to S(8, −5).

i.e.

the distance traveled is:

Hence, the total length of the biking trail is:
