#22: 10.2 gallons for $2.59 each = 10.2 x 2.59, which rounded is $26.42.
#23: 12 pieces that are 6.45 in wide each = 12 x 6.45, which is 77.4 in.
#25: Aaron started with $38.
$22.47 + $8.53 + $6.50 is $37.50.
38.00 - 37.50 is .50 or 50 cents.
Hope that helps!
The vertex is at (0, 3) so y=a(x-0)²+3, which is y=ax²+3
next, use a given point to find a: 10=a(3)²+3, so 9a=7, a=7/9
the equation is then y=
as for the first question, the shape is an ellipse, the domain is -5≤x≤5, the range is -3≤y≤3
the equation can be written as :
Answer:
Hence new dimension of new garden is 27 by 51
Step-by-step explanation:
Initial dimension of his square garden = X by X
Final dimension of his rectangular garden = L by B
Perimeter of his garden = 60 = 4X
Hence X = 60/4 = 15 ft
Area of the square garden = 15 x 15 = 225 ft²
New garden dimensions
L + 3 = 2W-----------------Eqn 1
2(L+W) = 60---------------Eqn 2 (since both shapes have the same perimeter)
solving both equations simultaneously
From equation one L = 2W-3, it's now substituted into equation 2
from equation 2, 2L+2W= 60
Hence 2(2W-3) + 2W = 60
W = 27 ft
L= 2(27)-3= 51 ft
Hence length and breadth of new garden is 27 by 51
<span>A two-column geometric proof consists of a list of statements, and the reasons that we know those statements are true. The statements are listed in a column on the left, and the reasons for which the statements can be made are listed in the right column. Every step of the proof (that is, every conclusion that is made) is a row in the two-column proof.</span>
Answer:
40%
Step-by-step explanation:
1.50 - 0.90 = 0.60
0.60 cents are saved.
0.4 = 40%
hope this helps :)
