Add -5 on both sides
and you get y>-10
Answer:
Samantha worked 26 hours and Adriana worked 13 hours.
Step-by-step explanation:
Let s = the number of hours that Samantha worked
Let a = the number of hours that Adriana worked
s = 2a
s + a = 39
2a + a = 39
3a = 39
a = 13
To determine the radius of the cone, we make use of the lateral surface area of the cone. The lateral surface of an object is the area of all the sides of a certain object. For a cone, it is the product of pi, the radius and the slant height (lateral height). We calculate as follows:
Lateral Surface Area = πrh
47.1 = πr(6)
r = 2.5 cm
1,2,3,6,7,14,21,42 that's the factors
How to find the area of a circle:
The area of a circle can be found by multiplying pi ( π = 3.14) by the square of the radius
If a circle has a radius of 4, its area is 3.14*4*4=50.24
If you know the diameter, the radius is 1/2 as large.
