2*256=512

The area of both playgrounds combined is 512 square meters

I want answer

KIM [24]

(Assuming all these lines are parallel to each other)

Angle x = 70, because it is corresponding to the 70 angle.

Angle y = 70, because it is corresponding to x

Angle z = 70, because angle z and angle y are alternate angles

(corresponding angles and alternate angles are equal to each other with the condition of parallel lines)

each morning a gardener uses 24 3/4 gallons of water from a barrel. each afternoon, she adds 15 1/4 gallons of water to the barr

Nimfa-mama [501]

Answer:

$47\frac {1}{2}\ gallons$

Step-by-step explanation:

Assuming that the tank is only for agricultural use, also no significant leakages then at the end of the day, the amount consumed will be equivalent to $24\frac {3}{4}-\ 15\frac {1}{4}=9\frac {1}{2}$

For 5 days, the quantity reduces by 9.5*5=47.5 gallons

Therefore, the barrel would have changed by $47\frac {1}{2}\ gallons$
