Answer:

Yes, the ratio is proportional

Step-by-step explanation:

given 4.2 : 1.5 =? 12.6 : 4.5 is it proportional

it must follow the means extremes property

\frac{a}{b} = \frac{c}{d}

a*d = b*c, so let's plug in the values

\frac{4.2}{1.5} =? \frac{12.4}{4.5}

(4.2)*(4.5) =? (1.5)*(12.6)

18.9 = 18.9 which is true; therefore the ratio is proportional

Answer:

No

All the numbers have to be multiplied by the same amount for it to be proportional

A proportional amount to 4:2:1:5 would be 12:6:3:15

They have all been multiplied by the same number 3

An artist is constructing a piece of art in the shape of rectangle. The artist wants to use string to tightly tie each vertex of
Liula [17]

Answer:

  65.8 ft

Step-by-step explanation:

The number of strings required to tie each vertex to the other three will be ...

  (4)(3)/2 = 6

Those strings will be perimeter strings plus two diagonal strings. The lengths of the perimeter strings are given as 12 ft and 7 ft. The lengths of the diagonal strings can be found using the Pythagorean theorem.

  d² = 12² +7² = 144 +49 = 193

  d = √193 ≈ 13.892

Then the total length of all strings is ...

  L = 2(12.0 +7.0 +13.9) = 65.8 . . . . feet

The artist will need 65.8 feet of string.

Answer:

perimeter =22m

area=28square meter

perimeter of rectangle=4l

22m=4l

22÷4=l

5.5=l

l=5.5m

area of rectangle =l×b

28=5.5×b

28÷5.5=b

5.09=b

b=5.09m

length =5.5m and breadth =5.09m answer !!!!
