Answer:

<h2>19.596 feet</h2>

Step-by-step explanation:

Use the pythagorean theorem.

a^2 + b^2 = c^2

a = 20ft

c = 28ft

400 + b^2 = 784

b^2 = 384

b = 19.596

Write the inequality!! Connie’s dog Fido weighs 35 pounds. Her vet placed Fido on a diet. What inequality can you write to find

Butoxors [25]

Answer: $\frac{35-28}{x} \leq 6$

Step-by-step explanation:

Let x be the average number of pounds Fido must loss.

Since, the initial weight of Fido is 35 pounds.

And, After losing the weight, the new weight of Fido in pounds = 28 pounds.

Then the time taken for losing the weight

= $\frac{\text{ The weight it losses}}{\text{ Average of losing weight per month}}$

= $\frac{35-28}{x}$

According to the question, it must lose weight within 6 months,

Thus, $\frac{35-28}{x}\leq 6$

Which is the required inequality to find the average number of pounds per month.

By solving it we, get, $x\geq \frac{7}{6}$
