Answer:
401
Step-by-step explanation:
The perimeter is three times the old.
Because if the formula is
P= a+b+c and you triple each side you get P= 3a+3b+3c so it would be three times as big as the old perimeter.
For example if your equation is
P=3+2+5 (which equals 10) and then you multiply each side by 3 your new formula is P= (3•3) (3•2) (3•5) which equals 30. 30 is three times larger than 10.
Hope this helps!
Answer:
Step-by-step explanation:
A(10,10) B(b,10b)
ax-2y=30
Divide both parts of the equation by 10:
a=5
Hence,
5x-2y=30
5(b)-2(10b)=30
5b-20b=30
-15b=30
Divide both parts of the equation by -15:
b=-2
Thus,
a=5 b=-2
Divide both parts of the equation by 2:
2.5x-15=y
The equation of the perpendiqular bisector
Hence,
Answer:
Since, company A charge of $423.5 is less than company B charge of $450
Hence,
Company A should be hired to get the better deal.
Step-by-step explanation:
Dimension of room: 11 * 14 foot
Area of rectangle is given by length * width
Thus,
area of room using above formula = 11*14 square foot = 154 square foot
For company A
charge for 1 square foot = $2.75
Charge for room = charge for 1 square foot * area of room
= 2.75 * 154 = 423.5
Thus, Total money charged by company A as calculated above is $423.5
Given,
company B charges $450 per room
Since, company A charge of $423.5 is less than company B charge of $450
Hence,
Company A should be hired to get the better deal.
