Answer:
Step-by-step explanation:
1. 882/24 = 36.75 or 37 crates of milk
2. 3712 x 6 = 1902 yoghurts were sold
3. 94291 - 63512 = 30779
4. 91429 is greater by (91429-42929) = 48500.
10. 7 hours 55 mins
1 month and 3 days or 33 days.

Answer:
Side length of each booth is 8.35 ft approximately.
Step-by-step explanation:
There are 11 companies set up equal sized square booths in a row along one wall of a convention center.
Now, refer the diagram to answer the problem.
It is given area is 1200.
So, length x width =1200
(11x+24)(x+2)=1200
Multiply using FOIL method.
+22x+24x+48=1200
+46x+48-1200=0
+46x-1152=0
Solve using quadratic formula
x=
x=
x=
Simplify it
Simplify to get two values for x.
x=8.35; x=-12.67
Here negative does not work.
Side length of each booth is 8.35 ft.
Answer:
X=7
Step-by-step explanation:
-5×2+3x=11
(-5×2)+3x=11
-10+3x=11
3x=11+10
3x=21
x=21÷3
x=7
Answer:
Perimeter is 130r units
Area is n*r^2 square units
Step-by-step explanation:
So, something special happens to perimeter and area if you scale a figure by some factor. let's say you make a figure twice as big, well, the perimeter also gets twice as big. Area though will get 4 times as big. more generally, if you scale a figure by x, the perimeter also scales by x, while the area scales by x^2.
So for this triangle, the perimeter of abc is 30 + 40 + 60, then when you scale them by r the perimeter becomes 30r + 40r + 60r or (30 + 40 +60)r. of course 30 + 60 + 40 is 130 so the perimeter of xyz is 130r
Now for area, the problem just vices us the area as n. Scaling the sides by r makes the area n*r^2. This is for all shapes. If you want to check try on a random triangle, or more easily a square
