Quadrilateral SQUA is a square with sides measuring 25mm. Quadrilateral AQER is also a square.What is the length diagonal RQ

svet-max [94.6K]

The square has 4 sides of the same measure.

If square SQUA has a side measuring 25 mm, it means side QU measures the same.

Also, if quadrilateral AQER is a square two, then its diagonals bisect each other, then QU is equal to UR.

Thus, QR measures:

$\begin{gathered} QR=QU+UR \\ QR=25\operatorname{mm}+25\operatorname{mm} \\ QR=50\operatorname{mm} \end{gathered}$

The answer is 50 mm

A farmer pumps water from an irrigation well to water his field. the time it takes to water the field varies inversely with the

KonstantinChe [14]

In order to answer this question, we use the concept of ratio and proportion wherein we use the equation,
R1 / T2 = R2 / T1
where R is for rate and T is for time. Substituting the known values to the equation,
(600)/x = (400)/ 20
The value of x from the equation is 30. Thus, it will take 30 hours if the rate was adjusted to 400 gallons per minute.

Use matrices to write the equation of the function in the form y = mx + b that contains the points

Fofino [41]

The line has a slope of -6 and a y intercept of 7.

The linear equation is given by:

y = mx + b;

where m is the slope of the line, b is the y intercept, y, x are variables.

The equation of the line passing through the points (6.-29) and (-4,31) is:

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-(-29)=\frac{31-(-29)}{-4-6}(x-6)\\\\y+29=-6(x-6)\\\\y=-6x+7$
