Answer:
1.26 corect answer
Step-by-step explanation:
the surface area of a sphere is 4*pi*r^2
so r is sqrt(20/pi) which is sqrt(1.59) = 1.26
1. Take out the constants
-(2 x 3 x 4 x 2)xxyy^3
2. Simplify 2 x 3 x 4 x 2 to 48
-48xxyy^3
3. Use Product Rule: x^ax^b = x^a+b
-48x^1+1y^1+3
4. Simplify 1 + 1 to 2
-48x^2y^1+3
5. Simplify 1 + 3 to 4
-48x^2y^4
Answer:
Y intercept is the value of y when x is equaled 0.
Step-by-step explanation:
Slope intercept form is
y = mx + b
In this equation, b is the y intercept.
Answer:
This is what I got, the second one, the third one, and the fifth one.
Step-by-step explanation:
A + s = 504
s = a + 54
a + (a + 54) = 504
2a + 54 = 504
2a = 504 - 54
2a = 450
a = 450/2
a = 225 <=== adults
a + s = 504
225 + s = 504
s = 504 - 225
s = 279 <=== students
