The perimeter of an equilateral triangle is 11 inches more than the perimeter of a square, and the side of the triangle is 6 inc
uysha [10]

Answer:

13 inches

Step-by-step explanation:

Let P(t) and P(s) be the perimeters of the equilateral triangle and square respectively. Similarly, t and s be the side lengths of equilateral triangle and square respectively.

According to the first condition :

(Perimeter of an equilateral triangle is 11 inches more than the perimeter of a square)

\implies P(t) = P(s) + 11

\implies 3t = 4s + 11....(1)

According to the second condition :

(The side of the triangle is 6 inches longer than the side of the square)

\implies t = s + 6....(2)

From equations (1) & (2)

3(s + 6) = 4s + 11

3s + 18 = 4s + 11

3s - 4s = 11 - 18

-s = - 7

s = 7 inches

\because t = s + 6

\because t = 7 + 6

\because t = 13\: inches

Thus the side of the triangle is 13 inches long.

Which dot plot has the largest range?
romanna [79]

Answer:

Calico Crayfish has the largest range ⇒ The range = 9

Step-by-step explanation:

∵ The rang is the difference between the largest value

   and the smallest value

In the Calico Crayfish the largest value is 10 and the smallest value is 1

∴ The range = 10 - 1 = 9

In the Zebra Mussel the largest value is 10 and the smallest value is 2

∴ The range = 10 - 2 = 8

In the Blue-back Herring the largest value is 10 and the smallest value is 4

∴ The range = 10 - 4 = 6

In the Shield Darter the largest value is 9 and the smallest value is 2

∴ The range = 9 - 2 = 7

∴ The largest range is 9 in Calico Crayfish
