With six students absent, there are 26 students, so 78/26 = 3 colored pencils for each student.
Selection B is appropriate.
Answer:
3x - 12 is an expression equivalent to 3(x - 4)
Explanation:
Another way to write this expression is to simplify it. To simplify the given expression, multiply the number three by the x and negative four inside the parentheses.
3(x - 4)
3x - 12
Therefore, 3x - 12 is the simplified version of the expression 3(x - 4). In other words, 3x - 12 is an expression equivalent to 3(x - 4).
Answer:
192 
Step-by-step explanation:
Given that
Volume of spherical sculpture = 256 ft³
is used as 3.
To find:
Surface area of sculpture = ?
Solution:
First of all, let us learn about the formula for Volume and Surface Area of Sphere:
1. 
2. 
Given volume is 256 ft³.

Now, let us put r = 4 in the formula of Surface Area to find the value of Surface Area:

So, approximate surface area of sculpture is 192
.
Answer:
2
Step-by-step explanation:
sin²a + cos²a + sec²a - tan²a
sin²a + cos²a = 1
1 + tan²a = sec²a
So, sec²a - tan²a = 1
sin²a + cos²a + sec²a - tan²a
= 1 + 1 = 2
