Square NOPQ is dilated by a scale factor of to form square N'O'P'Q'. Side N'O' measures 4. What is the measure of side NO?

KIM [24]

$\begin{gathered} \text{NOPQ was dilated to N'O'P'Q'} \\ \text{The scale factor is }\frac{2}{3} \\ N^{\prime}O^{\prime}=4 \\ N^{\prime}O^{\prime}=\frac{2}{3}NO \\ 4=\frac{2}{3}NO \\ \text{cross multiply} \\ 12=2NO \\ NO=\frac{12}{2} \\ NO=6 \end{gathered}$

Solve for x: -2(x + 3) = -4x + 20

Phantasy [73]

Answer:

Step-by-step explanation:

Lets start with 13

-2(13 + 3) = -4(13) + 20

-32 = -52 + 20

-32 = -32

x = 1 basically

now 19

-2(19 + 3) = -4(19) +20

-44 = -76 + 20

-44 = -56

so divide those

-2(31 + 3) = -4(31) + 20

-68 = -124 + 20

-68 = -104

divide them

-2(37 + 3) = -4(37) + 20

-80 = -148 + 20

-80 = -128

A 2800 gallon swimming pool is being fr

Nimfa-mama [501]

The pool is drained at 700 gallon per hour , so you need to multiply the number of hours ( t) by 700 to find the total number of gallons after a certain amount of hours, this would be written as 700t.

You would then need to subtract that amount from the starting value of 28,000.

This would make the equation g = 28,000 - 700t.

The value of q varies directly withp2,andq=16whenp=2.What is the value of q whenp=12?

lisov135 [29]

$\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------$

$\bf \textit{q varies directly with p}^2\qquad q=kp^2
\\\\\\
\textit{we also know that }
\begin{cases}
q=16\\
p=2
\end{cases}\implies 16=k2^2\implies \cfrac{16}{2^2}=k
\\\\\\
4=k\qquad therefore\qquad \boxed{q=4p^2}
\\\\\\
\textit{when p = 12, what is \underline{q}?}\qquad q=4(12^2)$
