The width of a rectangle is only 15% of its length. If the perimeter of the rectangle is 46, what is the length

sveta [45]

Answer:

20 units

Step-by-step explanation:

Let the length be x. According to the question,

Length = x
Width = 15% of the length

➝ Width = 15% of the length

➝ Width = 15/100x

➝ Width = 3/20x

We have the perimeter of the rectangle that is 46 units.

$\longrightarrow \sf {Perimeter_{(Rec.)} = 2(L + W) } \\$

$\longrightarrow \sf {46= 2\Bigg \lgroup x + \dfrac{3}{20}x \Bigg \rgroup } \\$

$\longrightarrow \sf {46= 2\Bigg \lgroup \dfrac{20x + 3x}{20} \Bigg \rgroup } \\$

$\longrightarrow \sf {46= 2\Bigg \lgroup \dfrac{23x}{20} \Bigg \rgroup } \\$

$\longrightarrow \sf {\dfrac{46}{2}= \dfrac{23x}{20}} \\$

$\longrightarrow \sf {23= \dfrac{23x}{20}} \\$

$\longrightarrow \sf {23 \times 20 = 23x} \\$

$\longrightarrow \sf {460= 23x} \\$

$\longrightarrow \sf {\cancel{\dfrac{460}{23}} = x} \\$

$\longrightarrow \underline{\boxed{ \bf {20\; units = x}}} \\$

Therefore, length of the rectangle is 20 units.

PLZ HELP I WILL MARK BRAINLIEST A rectangular prism has a base that is 5 cm by 7 cm and a height of 12 cm. If all dimensions are

Aliun [14]

Answer:

When the dimensions are doubled, the volume is eight times the original volume.

Step-by-step explanation:

difference in volume = volume of prism with dimensions doubled / original volume of prism

Volume of a prism = length x width x height

original volume of prism = 7 x 5 x 12 = 420

doubled dimensions of prism = (7x2) x (5x2) x (12 x 2)

volume = 14 x 10 x 24 = 3360

3360 / 420 = 8
