A lawn mower cost $470 when new and is expected to last 10 years. What will it be worth in 7.5 years? (Assume the lawn mower has
USPshnik [31]
Answer: 117.5
Explanation: Assuming that after 10 years the lawn mower would have a value of 0. We can evenly divide $470 by the amount of years.
$750/10 = $75
We would then multiply 75*7.5 years to then realize the value lost over that amount of time would be $352.5, subtracting that from the original value of $470 would then be 117.5

If l is a vertical line passing through points A(a, b) and B(c, d), then what can you say about a and c?
KonstantinChe [14]

Answer:

a and c have the same x value

Step-by-step explanation:

The line is going up, so that means there is a change in the y-values

If the line was horizontal, then there would be a change in the x-values.

Just picture it or draw it out, it would also help

Find the value of y for which line a is parallel to line b
Vsevolod [243]
As is shown in the figure attached:

1. "A" and 76º are congruents, because they are Alternate Interior angles, so A=76º.
 
 2. "D" and "x" are congruents, because they are Alternate Interior angles, so x=38º.
 
 3. "A", "B" and "C" form a the triangle ABC. Then, we remember sum of the interior angles of a triangle is 180º, so we have:
 
 76º+38º+B=180º
 B=180º-76º-38º
 B=66º
 
 4. By definition, an exterior angle of a triangle is equal to the sum of the opposite interior angles to it. So, we can calculate the exterior angle "y" of the triangle ABC, as follows:
 
 The opposite angles are: 76º and 66ª. Then, we obtain:
 
 y=76º+66º
 y=142º

 Therefore, the answer is: The value of y is 142º.
