The eastern continental trail is 15 times longer than the Erie canal way trail. The combined length of the hiking trails is 5,76

Lena [83]

The length of eastern continental trail is 5400 miles and length of erie canal trail is 360 miles.

Step-by-step explanation:

Given,

Combined length of both trails = 5760 miles

Let,

x be the length of eatern continental trail.

y be the length of Erie canal trail.

According to given statement;

x+y=5760 Eqn 1

x = 15y Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$15y+y=5760\\16y=5760$

Dividing both sides by 16

$\frac{16y}{16}=\frac{5760}{16}\\y=360\\$

Putting y=360 in Eqn 2

$x=15(360)\\x=5400$

The length of eastern continental trail is 5400 miles and length of erie canal trail is 360 miles.

Rectangle ABCD was dilated to create rectangle A'B'C'D. Triangle A B C D is dilated to form triangle A prime B prime C prime D.

MArishka [77]

Answer:

AB=6 Units

Step-by-step explanation:

Given the following lengths of rectangle ABCD and its dilation A'B'C'D' respectively

A'B' = 15 Units
B'C' = 9.5 Units
BC = 3.8 units

We are to determine the length of AB. To do this, we first determine the dilation factor.

$D$ilation Factor =\dfrac{B'C'}{BC} =\dfrac{9.5}{3.8} =2.5$

Therefore:

$\dfrac{A'B'}{AB} =2.5\\\\\dfrac{15}{AB} =2.5\\$Cross multiply \\ 2.5 AB =15 \\AB=15 \div 2.5\\$Therefore, AB=6 Units$
