If ghj=lmk with a scale factore of 5:6 find perimeter of ghj
jeyben [28]

Perimeter of the triangle GHJ is 35cm.

<h3>What is perimeter?</h3>

A perimeter is a closed path that includes, encircles, or delineates a one-dimensional length or a shape with two dimensions.

The perimeter's units are equal to the sides of a polygon's length.

Given Data

The perimeter of a triangle is, by definition, the total length of its sides.

Next, the triangle LMK's perimeter is:

ΔLMK = 14+ 11 + 17

ΔLMK = 42

The perimeter of the triangle LMK must be multiplied by the scale factor if both triangles are congruent and the scale factor is 5:6 (which can be written as a fraction: \frac{5}{6}).

Next, you have that the triangle GHJ perimeter is:

ΔGHJ = 4(\frac{5}{6})

ΔGHJ = 35

Perimeter of the triangle GHJ is 35cm.

Jeffrey and Frank walk at different speeds.Frank’s walking speed can be represented by the equation y=85x, where is the time in
kolezko [41]

Answer:

Option (C)

Option (C)

Option (A)

Step-by-step explanation:

Part A.

Frank's walking speed can be represented by the equation.

Equation representing the speed is,

y = 85x

\frac{y}{x}=85

Therefore, walking speed of Frank = 85 meters per minute.

Option (C) will be the answer.

Part B.

Distance walked over the time by Jeffrey is given by the graph attached.

Equation for the speed will be,

y = (\frac{400}{5})x

y = 80x

Therefore, walking speed of Jeffrey = 80 meters per minute

Difference in the speed of Frank and Jeffrey = 85 - 80 = 5 meters per minute.

Jeffery walks 5 meters per minute slower than Frank.

Option (C) will be the answer.

Part (C)

Distance traveled by Frank in 16 minutes,

y = 85(16) = 1360 meters

Time taken to travel the same distance by Jeffrey will be,

1360 = 80x

x = \frac{1360}{80}=17 meters per minute

Option (A) will be the answer.
