An architect designs a rectangular flower garden such that the width is exactly two-thirds of the length. If 340 feet of antique

KIM [24]

Answer:

The dimensions of the garden is 102 feet by 68 feet

Step-by-step explanation:

Here, we want to get the width and length of the garden

The perimeter is represented by the length of the fencing

From the question;

w = 2l/3

The formula for the perimeter is;

P = 2(l + w)

Thus;

340 = 2(l + 2l/3)

170 = (l + 2l/3)

Multiply through by 3

510 = 3l + 2l

5l = 510

l = 102 feet

w = 2/3 * l

w = 2/3 * 102

w = 68 feet

How are the solutions to the following two equations related m+5=72 m+72=5

EastWind [94]

To see how they are related, let us solve the two equations.

FIRST EQUATION

$m + 5 = 72$

$\rightarrow \: m = 72 - 5$

$\rightarrow \: m = 67$

SECOND EQUATION

$m + 72 = 5$

$\rightarrow \: m = 5 - 72$

$\rightarrow \: m = - 67$

Hence the solutions to the two equations are ADDITIVE INVERSE of each other.

Can any math genius help me with this

vovangra [49]

Here's my working for 1) You need to find the exterior angle, then divide by 360 to find the number of sides:

Applying these steps : 

180 (Interior Angles) - 162 = 18 (Exterior angle)

360 ÷ 18 is 20 sides 

For 2)

Its the same method, so apply the steps:

180 - 175 = 5

360 ÷ 5 = 72 sides 

Hope it helps! :)
