Haley measured the distances between her house and two of her friends' houses. ellen's house is 1.41 miles away from haley's, an

Arada [10]

Answer: Ellen's house is farther away by 898 feet.

Step-by-step explanation:

Given: The distance between Haley's house and Ellen's house = 1.41 miles

We know that 1 mile = 5,280 feet

Then, $1.41\text{ miles}=1.41\times5,280\text{ feet}=7,444.8\text{ feet}$

The distance between Haley's house and Dirk's house = 6,547 feet

Clearly, 6,547<7,444.8

And $7444.8-6547= 897.8\approx898$

Therefore, Ellen's house is farther away by 898 feet.

The perimeter of the rectangular playing field is 320 yards. the length of the field is 4 yards less than triple the width. what

fgiga [73]

Let the width be X
Then the length is X + 70
The perimeter is the sum of all sides
There are 2 widths (left side and right side) and 2 lengths (top and bottom)
Perimeter = 2 * width + 2 * length
Perimeter = 2 * X + 2 * (X+70)
Perimeter: 2 X + 2 X + 140 = 380
4 X = 380-140
4 X = 240
X = 240 / 4
X = 60
Width = 60 - the smaller of two sides
Length = X + 70 = 60 + 70 = 130 - the larger of two sides

Check:
<span> 2 * 60 + 2 * 130 = 380 </span>
