Answer:
12.25
Step-by-step explanation:
Remember PEMDAS!!
You would divide 3.5 to 2 first which is 1.75, then add 10.5 and 1.75 which equals 12.25.
P = ( )
E = exponents
M/D = Multiply/Divide

In this questions, there are a few functions with more/less than and equal to symbol.
1. Answer: f(x)= 3
f(x)= 2<x ≤3
The x is [more than 2] and [less than 3] or [equal to 3]. The number that will fulfill the condition would be only 3 since 3 is [more than 2] and [equal to 3].
2. f(x)= 1
f(x)= 0<x ≤1
The x is [more than 0] and [less than 1] or [equal to 1]. The number that will fulfill the condition would be only 1 since 1 is [more than 0] and [equal to 1].
3. f(x)= x
f(x)= 1≤x ≤2
The x is [more than 1] or [equal to 1] and [less than 2] or [equal to 2]. The number that will fulfill the condition would be
1, since 1 is [equal to 1] and [less than 2]
2, since 2 is [more than 1] and [equal to 2]
The graph that follow the value would be: f(x)= x
4. Answer: f(x)= 4
f(x)= 3<x ≤4
The x is [more than 3] and [less than 4] or [equal to 4]. The number that will fulfill the condition would be only 4 since 4 is [more than 3] and [equal to 4].
Answer:
<u>-53</u>, f(n) = -6(n-1) + 13
Step-by-step explanation:
given the equation to this linear/arithmetic sequence for the nth term: f(n) = -6(n-1) + 13
f(12) = -6(12-1) + 13
f(12) = -6(11) + 13
f(12) = -66 + 13
f(12) = -53
*substitute and simplify*
______________
f(n) = f(1) + d(n-1)
given f(1) = 13, f(2) = 7, and f(3) = 1
7-13 = 1-7 = <u>-6</u> = d
= f(1) + d(n-1)
f(1) = <u>13</u> so
the equation must be f(n) = <u>13</u> <u>-</u><u> </u><u>6</u>(n-1) or -6(n-1) + 13
You divide the width of the book by the number of sheets of paper in order to get the thickness of each of the pieces of paper.
The artist needs 180.5 square inches of material to create the kite.
Step-by-step explanation:
Step 1; The area of a kite is calculated by multiplying 
with the product of the diagonal lengths. Assume p is the diagonal length from the left to the right side and q is the diagonal length from the top to bottom.
p = 9.5 inches + 9.5 inches = 19 inches.
q = 7 inches + 12 inches = 19 inches.
Step 2; Area of the given kite is found using p and q by the following method;
Area of the kite = × (19 × 19) = 180.5 square inches.
So the 
option is the amount of material she requires.
