X= 30/r is the answer because if you divide both sides by r you are left with x=30/r because you cant divide 30 by r

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

NNADVOKAT [17]

Answer:

l=102 feet, w=68 feet

Step-by-step explanation:

Let w=width and l=length

P=2l + 2w

And we know that w=2/3l

So, using substitution...

340=2l + 2(2/3l)

340=2l + 4/3l

340=6/3l + 4/3l

340=10/3l (now multiply both sides by 3 to get rid of fraction)

1020=10l

So l=102

Now plug in to get w

2(102)+2w=340

204+2w=340

2w=136

w=68

Now check:

2(102)+2(68)=

204+136=

340 It works!

A particular model rocket kit uses the scale 1:144. The actual rocket is 168 ft tall. How tall will the model rocket be when com

Svetlanka [38]

Our basis is the given ratio of 1:44. The actual rocket is obviously larger than the model rocket. Thus, it means that for every 44 ft of the actual rocket, the scale of the model rocket would be 1 ft. Through ratio and proportion, the solution is as follows:

1/44 = x/168
x = 3.818 ft

<em>The height of the model rocket, is approximately 3.8 ft.</em>

Lee and Maya are collecting leaves for an art project lee collects 25/100 of the total number leaves needed. Maya collects 4/10

MrRissso [65]

Answer: The answer is $\dfrac{13}{20}.$

Step-by-step explanation: Given that Lee and Maya are collecting leaves for an art project. Let'x' be the total number of leaves needed in the project.

Then, the number of leaves collected by Lee is given by

$L_\ell=\dfrac{25}{100}x,$

and the fraction of the leaves collected by Maya is given by

$M_\ell=\dfrac{4}{10}x.$

Therefore, the total number of leaves collected by Lee and Maya altogether is

$L=L_\ell+M_\ell=\dfrac{25}{100}x+\dfrac{4}{10}x=\dfrac{25+40}{100}x=\dfrac{65}{100}x=\dfrac{13}{20}x.$

Thus, the total fraction of the leaves collected by Lee and Maya is

$\dfrac{13}{20}.$
