Answer:
The total cost to install the 1,200 ft of the pipe is $21000.
Step-by-step explanation:
Consider the provided information.
You buy 900 ft pipe with a cost of $15 per foot and the remaining 300 ft pipe with a cost of $25 per foot.
Therefore, the total cost is:
Hence, the total cost to install the 1,200 ft of the pipe is $21000.
Answer:
s = 53
Step-by-step explanation:
We know that the three angle measures in a triangle add up to 180°. so…
(s - 20°) + 2s + 41° = 180°
Step 1. Subtract 41 from both sides
(s - 20°) + 2s = 139°
Step 2. Combine like terms
3s - 20 = 139°
Step 3. Add 20 from both sides
3s = 159
Step 4. Solve for s
s = 159/3
s = 53
Answer:
the answer is 8:1 so 8/1
Step-by-step explanation:
Step-by-step explanation:
the area of a triangle is always
baseline × height / 2
where baseline and height are perpendicular (at a 90° angle) to each other.
so, in our case the area is
7 × 2 / 2 = 7 × 1 = 7 units²
Well, you are trying to simplify the numbers and the equation. You are trying to get the smallest possible number or solution. A difference between the two is that polynomials have factors and variables. Numbers are just numbers. With a polynomial, you have to combine like terms and try to reduce the length of the equation. You may not always fully solve a polynomial. With numbers, you probably will get an exact numeral answer.
