At a pumpkin patch, if Armando guesses the weight of his pumpkin within 0.3 pounds, he gets to take the pumpkin home for free. I

Reil [10]

Answer: last option

Step-by-step explanation:

You know that the weight of his pumpkin 4.9 pounds and that, if he guesses its weight within 0.3 pounds, he will get the pumpkin for free.

Then, to find the minimum weight he can guess in order to get his pumpkin for free, it's necessary to write the expression:

$x-0.3=4.9$

Rewriting it:

$x-4.9=0.3$

To find the maximum weight he can guess in order to get his pumpkin for free, it's necessary to write the expression:

$x+0.3=4.9$

Rewriting it:

$x-4.9=-0.3$

A park is rectangular with a length of ⅔ miles. If the area of the park is 3/9 square miles, what is the width?

Zielflug [23.3K]

Answer:

Area of the rectangular park = 2/3 square mile

Let us assume the width of the rectangular park = x

Then

The length of the rectangular park = 2 2/3 * x mile

= 8x/3 mile

Then

Area of the rectangular park = Length * Width

2/3 = (8x/3) * x

2/3 = 8x^2/3

(2 * 3)/3 = 8x^2

2 = 8x^2

x^2 = 2/8

x^2 = 1/4

x^2 = (1/2)^2

x = 1/2

So the width of the park is 1/2 feet.
