Answer:
1500
Step-by-step explanation:
we can do simple triangle numbers to do this. 4 more seats per row. we take 10 which is the first row and add the last row which 110 because 4*25 rows is 100 more. now we can half the rows to 12.5 and multiply that by the 120 and we get 1500 and we are done

Answer:
The perimeter is approximately 18 units.
Step-by-step explanation:
The dilation causes the rectangle to shrink, so the side lengths shrink as well. The side with 10 units go down to 7.5, and the sides with 2 units go down to 1.5.
These numbers multiplied by 2 and then added together gives an answer of 18 units.
Answer:
m∠R = 39 degrees
Step-by-step explanation:
As complementary angles add up to 90 degrees, we can set up an equation to get x then find the measure of ∠R:
m∠R + m∠S = 90
2x+7+4x-13=90
6x+7-13=90
6x-6=90
6x=96
x=16
Since m∠R = (2x+7), 2x+7 would be 2(16)+7 or 39 degrees. So in conclusion, m∠R = 39 degrees
Answer:
$484.97.
Step-by-step explanation:
For a minimum amount of wall/fencing the garden has to be a square.
That would make each side of the garden = √48 dollars.
So the smallest amount would be √48 * 3 * 20 +√48 * 10
= $484.97.
