Answer:
<em>15 miles</em> is the correct answer.
Step-by-step explanation:
It is given that Post office is at the intersection point of First Street and Main Street and forms a right angle.
Please refer to the attached image, let us suppose post office is at point P.
Intersection of Oak street and First street is towards North and
Intersection of Oak street and Main street is towards East
PQ represents the Main Street and PR represents the First Street.
It is given that Car A drives 21 miles on main street to reach oak street
<u>To find:</u>
How far will car B have to travel on first street to get to oak street?
i.e. PR = ?
<u>Solution:</u>
By trigonometric rules we know that
Here , perpendicular is PQ i.e. 21 miles and Base is PR
Hence, <em>15 miles</em> is the correct answer.
X+1=y and 3y-7=2x are your two equations.
Substitute x+1 in for y
3(x+1)-7=2x
3x+3-7=2x
x-4=0
x=4
Plug in 4 for x in either equation to solve for y
x+1=y
4+1=y
5=y
x=4 and y=5
Hope I could help!
For this case we have that the change in the value of the chair is given by:
x-0.66x = 0.34x
The percentage of decrease is given by:
(0.34) * (100) = 34%
Therefore, the chair had a decrease in the cost of 34%
Answer:
c) 34% decrease
