A garden is going to be built in the city park in the shape of a parallelogram with a rectangular walkway through it. The garden

lesya692 [45]

Left triangle area
.. (1/2)*(30 ft)*(72 ft) = 1080 ft^2

Middle walkway area
.. (20 ft)*(72 ft) = 1440 ft^2

Right triangle area
.. same as left triangle area, 1080 ft^2

Total area
.. 1080 ft^2 +1440 ft^2 +1080 ft^2 = 3600 ft^2

_____
Check:
Parallelogram area = base*height = (50 ft)*(72 ft) = 3600 ft^2

Find the LCM of 7 and 13

Korolek [52]

LCM stands for Least Common Multiple.

The LCM of two numbers is the lowest number that can divide into the two original numbers.

For most numbers, you can find the LCM by simply multiplying the two numbers:

$7 \cdot 13 = \boxed{91}$

The LCM of 7 and 13 will be 91.

4. What is the system of equations that describes the following graph?

GarryVolchara [31]

Answer:

The system of inequalities is

$y$

$y>0.25x$

Step-by-step explanation:

step 1

Find the equation of the dashed line with negative slope

The line passes through the points

(0,-2) and (-2,0)

Find the slope

$m=(0+2)/(-2-0)=-1$

Find the equation of the line in slope intercept form

$y=mx+b$

we have

$m=-1\\b=-2$

substitute

$y=-x-2$

The solution of the inequality is the shaded area below the dashed line

therefore

The equation of the inequality A is

$y$

step 2

Find the equation of the dashed line with positive slope

The line passes through the points

(0,0) and (4,1)

Find the slope

$m=(1-0)/(4-0)=0.25$

Find the equation of the line (direct variation)

$y=kx$

we have

$k=0.25$

substitute

$y=0.25x$

The solution of the inequality is the shaded area above the dashed line

therefore

The equation of the inequality B is

$y>0.25x$

therefore

The system of inequalities is

$y$

$y>0.25x$
