Answer:
2.25×3
Step-by-step explanation:
2 1/4 is equal to 2.25. So a expression could be 2.25×3.
Answer:
The answer to your question is Area = 37500 ft²
Step-by-step explanation:
Data
lawn 1 lawn 2
width = 550 ft width = 250 ft
Area = 181500 ft² Area = ?
Process
1.- Find the length of lawn 1
Area = length x width
-solve for length
length = Area/width
-Substitution
length = 181 500 ft²/ 550
-result
length = 330 ft
2.- Find the length of lawn 1 using ratios and proportions
550 : 330 :: 250 : x
x = (250 x 330) / 550
x = 150 ft
3.- Find the area of lawn 2
-Substitution
Area = 250 x 150
-Result
Area = 37500 ft²
Answer:
the answer is A
Step-by-step explanation:
b and d are wrong based on the first part of the polynomial being of a low value (3x^10 is highest) and c is wrong based on the fact that 2x^2 is higher than x^6.

Answer:
(x)^2 (y)^2
---------- + --------- = 1

Step-by-step explanation:
The standard equation for an ellipse is
(x-h)^2 (y-k)^2
---------- + --------- = 1
a^2 b^2
The center is at (h,k)
The vertices are at (h±a, k)
The foci are at (h±c,k )
Where c is sqrt(a^2 - b^2)
It is centered at the origin so h,k are zero
(x)^2 (y)^2
---------- + --------- = 1
a^2 b^2
The center is at (0,0)
The vertices are at (0±a, 0)
The foci are at (0±c,0 )
The vertices are (±2,0) so a =2
The foci is 1
c = sqrt(a^2 - b^2)
1 = sqrt(2^2 - b^2)
Square each side
1 = 4-b^2
Subtract 4 from each side
1-4 = -b^2
-3 = -b^2
3= b^2
Take the square root
b=sqrt(3)
(x)^2 (y)^2
---------- + --------- = 1
