Answer:

Step-by-step explanation:

1. according to the condition

$\frac{price \ radio1}{price \ radio2} =\frac{x}{y}$

2. when the both prices are increased the ratio is

$\frac{x+20}{y+20}=\frac{5}{2}$

3. when the both prices are reduced the ratio is

$\frac{x-25}{y-25} =\frac{5}{1}$

4. using the equations written in steps 2&3 it is possible to make up the system of the two equations:

$\left \{ {{\frac{x+20}{y+20}=\frac{5}{2} } \atop {\frac{x-25}{y-25}= \frac{5}{1} }} \right.$

where x=160; y=52.

5. ration x:y=5.

If 90 feet of wire weighs 18 pounds, what will 110 feet of the same type of wire weigh

shtirl [24]

First, do 90/18, that will result in 5, 5 goes into 110 22 times, so I believe (I dont exacly think my methos is exactly enough) 110 ft of waire would weigh about 22 Pounds

You would calculate this answer with the Pythagorean theorem. The formula is a² + b² = c², which basically means that the sum of two sides squared would equal the side that is missing.
Currently, we are given 6.5 for side 1. The angle measurments we are given is 45º and 90º [the right angle], which means that if we subtract the sum of 45 and 90 from 180 [the total degree amount of every triangle] we can get the missing angle. With the missing angle, we can calculate the length of the second side.
45º + 90º = 135º. 180º - 135º = 45º.
Now that we have the angles of all three sides [45º, 90º, 45º] we can find the second length of the triangle. The fact that two angles are the same [45º] means that the length is also the same.
Thus proving that M is also 6.5 in length, we can square 6.5 and add both sides to each other once squared.
6.5² = 42.25.
42.25 + 42.25 = 84.5.
The square root of 84.5 is 9.19, or 9.2 rounded.
