Answer:
(C) $1.12
Step-by-step explanation:
Multiply .75 by 7 to get the total pen cost. Then subtract that from $9.73 to get the total pencil cost, which is $4.48. Then divide by 4 since that is the amount of pencils.
Hope this helps
Answer:
2 Years, 9 Months, 3 Weeks, 5 Days and 1 Hour
Step-by-step explanation:
2,798.5 miles from L.A. to New York, an ant travels at 3 inches a second, we multiply 3 by 60 to get 120 inches a minute convert that into feet to get 10 feet, now multiply that by another 60 to get 600 feet an hour now multiply 600 by 24 to get 14,400 feet a day convert that into miles to get 2.72 miles a day now take 2.72 miles and divide that by the distance between the 2 cities to get about 1030 days, now if we put that into years, months, weeks, days and hours we get 2 Years, 9 Months, 3 Weeks, 5 Days and 1 Hour
The distance between both lines is 2.24 units
Step-by-step explanation:
There is no straight method to find the distance between two lines. The distance can be found out by finding a point on one line and then finding the distance of that point from the other line. The y-coordinate of point is obtained by putting any value of x in equation . The x and y combined give us the point.
Given
![y=2x\\Putting\ x=1\\y=2(1)\\y=2\\So, the\ point\ on\ y=2x\ is\ (1,2)](https://tex.z-dn.net/?f=y%3D2x%5C%5CPutting%5C%20x%3D1%5C%5Cy%3D2%281%29%5C%5Cy%3D2%5C%5CSo%2C%20the%5C%20point%5C%20on%5C%20y%3D2x%5C%20is%5C%20%281%2C2%29)
We have to find the distance of this point from y=2x+5
![y=2x+5\\Subtracting\ y\ from\ both\ sides\\y-y=2x+5-y\\2x-y+5=0](https://tex.z-dn.net/?f=y%3D2x%2B5%5C%5CSubtracting%5C%20y%5C%20from%5C%20both%5C%20sides%5C%5Cy-y%3D2x%2B5-y%5C%5C2x-y%2B5%3D0)
The formula for finding distance of a point (x,y) from a line is:
![d=\frac{|Ax+By+C|}{\sqrt{A^2+B^2}}](https://tex.z-dn.net/?f=d%3D%5Cfrac%7B%7CAx%2BBy%2BC%7C%7D%7B%5Csqrt%7BA%5E2%2BB%5E2%7D%7D)
A=2
B=-1
C=5
Putting the values in the formula
![d=\frac{|(2)(1)+(-1)(2)+5|}{\sqrt{(2)^2+(-1)^2}}\\d=\frac{|2-2+5|}{\sqrt{4+1}}\\d=\frac{|5|}{\sqrt{5}}\\d=\frac{5}{\sqrt{5}}\\d=2.236\ units](https://tex.z-dn.net/?f=d%3D%5Cfrac%7B%7C%282%29%281%29%2B%28-1%29%282%29%2B5%7C%7D%7B%5Csqrt%7B%282%29%5E2%2B%28-1%29%5E2%7D%7D%5C%5Cd%3D%5Cfrac%7B%7C2-2%2B5%7C%7D%7B%5Csqrt%7B4%2B1%7D%7D%5C%5Cd%3D%5Cfrac%7B%7C5%7C%7D%7B%5Csqrt%7B5%7D%7D%5C%5Cd%3D%5Cfrac%7B5%7D%7B%5Csqrt%7B5%7D%7D%5C%5Cd%3D2.236%5C%20units)
