An apartment complex allows small dogs that weigh less than 20 pounds. Show the possible weights of dogs that would be allowed.

A.
w < 20 and w must be a positive number.

B.
w < 20 and w may be a negative number.

C.
w > 20 and w must be a positive number.

D.
w > 20 and w may be a negative number.

Answers

since it is "less than," the inequality sign will be "<"

since a dog has to weigh something, and its weight cannot be negative, "w" will have to be a positive number

the correct answer is A

Solan and Julie each planted tulips. Of Solan's 20 tulips, 15 were red, while 10 of Julie's 20 tulips were red. Howmuch greater was Solan's fraction of red tulips than Julie's?

Answers

Answer: Fraction of red tulips of Solan is greater than fraction of red tulips of Julie by 0.75-0.5=0.25.

Step-by-step explanation:

Since we have given that

In case of Solan:

Number of red tulips = 15

Total number of tulips = 20

In case of Julie :

Number of red tulips = 10

Total number of tulips = 20

So, Fraction of red tulips of Solan is given by $(15)/(20)=0.75$

Fraction of red tulips of Julie is given by $(10)/(20)=0.50$

So, Fraction of red tulips of Solan is greater than fraction of red tulips of Julie by 0.75-0.5=0.25.

Answer:

Solan's tulip fraction was 1.5 times greater than Julie's.

Step-by-step explanation:

15/20 of Solan's tulips were red, while 10/20 of Julie's were red.

Solan's tulip fraction was 1.5 times greater than Julie's.
