Step-by-step explanation:
Answer:
the height of the cross section is 3 feet
Step-by-step explanation:
The computation of the height of the cross section is shown below:
Area = 1 ÷ 2 × (a + b) × h
39 = 1 ÷ 2 × (20 + 6) × h
39 = 1 ÷2 × 26 × h
39 = 26 ÷ 2 × h
39 = 13 × h
h = 39 ÷ 13
= 3 feet
hence, the height of the cross section is 3 feet
Answer:
C = $5 + $1.5(w)
Step-by-step explanation:
Given the following information :
Total shipping cost :
One time fee + fee based on package weight
Given the table :
Weight in pounds - - - - Total shipping cost($)
___4__________________11
___8__________________17
___12_________________23
___16_________________29
We can deduce from the table
For a package that weighs (w) 4 pounds
Total shipping cost = $11
Let one time fee = f
Fee based on weight = r
f + 4(r) = 11 - - - - - (1)
For a package that weighs (w) 8 pounds
Total shipping cost = $17
One time fee = f
Fee based on weight = r
f + 8r = 17 - - - - - (2)
From (1)
f = 11 - 4r - - - (3)
Substitute f = 11 - 4r in (2)
11 - 4r + 8r = 17
-4r + 8r = 17 - 11
4r = 6
r = 6/4
r = 1.5
Put r = 1.5 in (3)
f = 11 - 4(1.5)
f = 11 - 6
f = 5
Hence one time fee = $5
Charge based on weight = $1.5
Hence, Total shipping cost 'C' for a package weighing 'w' will be :
C = $5 + $1.5(w)
Answer:
14 - 13x
Step-by-step explanation:
take 13x + 1 away from 15
15 - (13x + 1) = 15 - 13x - 1 = 14 - 13x
Answer:
The answer is - x² - 12x + 9
Step-by-step explanation:
1. Using (a-b)²= a²-2ab+b², expand the expression
2. Collect the like terms.
