A cistern is leaking 0.25 liters of water per minute. Approximately how many gallons of water is the cistern losing per hour?

1 answer:

6 0

Hello,

$0.25 \dfrac{l}{min} = \dfrac{0.25\ l}{ \dfrac{1\ min}{60}} =15\ \dfrac{l}{h} \\

= \dfrac{15\ \dfrac{l}{h} }{3.78541\ \frac{l} {US\ gallon} })\\

= 3,96258265... \dfrac{US\ gallon}{h}$

Plss help! Question: Find a,b and c

Roman55 [17]

Answer:

See below, please

Step-by-step explanation:

The right：

${(y + c)}^{2} - b \times (x + a) \\ = ( {y}^{2} + 2yc + {c}^{2} ) - bx - ba =$

$= {y}^{2} - bx + 2cy + {c}^{2} - ab$

The left:

$= {y}^{2} - 7x - 18y + 109$

So, after comparing the right side and the left side of this equation, we know

$b = 7$

$2c = - 18 \\ so \\ c = - 9$

${c}^{2} - ab = 109$

So,

$a = \frac{ {c}^{2} - 109}{b} = \frac{ { (- 9)}^{2} - 109}{7} = \frac{ - 28}{7} = - 4$

To polygons are congruent when their corresponding sides are equal in length and their corresponding angles are equal in measure.
so he's not true

Solve for x in the parallelogram. The solution is x= units.

natka813 [3]

$\textit{area of a parallelogram}\\\\ A=bh~~ \begin{cases} b=base\\ h=height\\[-0.5em] \hrulefill\\ b=13\\ A=104\\ h=x \end{cases}\implies 104=(13)(x)\implies \cfrac{104}{13}=x\implies 8=x$
