Answer: 76.2

Step-by-step explanation:

Perimetar of isiscales triangle is calculated using  equation;

P=b+2a

b=9

P=49

lets find sides of triangle.

P-b=2a

a=(P-b)/2

a=49-9/2

a=40/2=20

If another triangle is similar that means that his base and sides are proportional to first triangle.

Base of first trianlge b₁=9

Base of similar triangle is b₂=14

use proportion to find out side of similar triangle:

b₁:b₂=9:14

a₁:a₂=9:14

a₁=20

20: a₂=9:14

a₂=14*20/9=280/9=31.1

Perimetar of second triangle is:

P₂=b₂+2a₂

P₂=14+2*31.1=14+62.2=76.2

If y is a positive integer, for how many different values of y is RootIndex 3 StartRoot StartFraction 144 Over y EndFraction End
Lelechka [254]

The value of y will be 18 or 144.

Given information:

The given expression is \sqrt[3]{\frac{144}{y} }.

It is required to find the values of y which are whole numbers.

Now, factorize 144 as,

144=2\times2\times2\times2\times3\times3\\144=2^3\times2\times3\times3

So, for the value of given expression to be a whole number, the value of y should be,

2\times3\times3=18 or 144.

For the above values of y, the given expression will be,

\sqrt[3]{\frac{144}{y} }=\sqrt[3]{\frac{144}{18} }\\=\sqrt[3]{8} =2\\\sqrt[3]{\frac{144}{y} }=\sqrt[3]{\frac{144}{144} }\\=\sqrt[3]{1} \\=1

Therefore, the value of y will be 18 or 144.
