Abby feeds her dog 1 1/2 cups of food each day, and Braxton feeds his dog 4 1/2 cups of food each day. In one week, how many tim
ddd [48]

Solution:

<u>Note that:</u>

  • Abby's dog: 1.5 cups of food
  • Braxton's dog: 4.5 cups of food

Looking at the information we got, we can say that Braxton's dog eats more. Let's put them into ratio form (Braxton's dog:Abby's dog)

  • => (Braxton's dog:Abby's dog) = 4.5:1.5

<u>Now, put them into fractions.</u>

  • => 4.5:1.5 = 4.5/1.5 = 3

We can conclude that Braxton's dog eats 3 times more food.

Johanna can jog 3,000 feet in 5 minutes. If she jogs at the same rate, how many feet can she jog in 8 minutes? *
olya-2409 [2.1K]
The answer is B (4,800)

Why?

Because we divide 3,500 feet by 5 and that will give us 600. Why we had to divide is because we need to find how many feet in minutes. So we do 600 times 8 and that gives us 4,800. Please mark me as branlist! Hope this helped! :)

Which statement is true about the function f(x)= -x?
rosijanka [135]

Answer:

The domain of the graph is all real numbers less than or equal to 0.

Step-by-step explanation:

Hello,

We know that we cannot take square root of negative numbers, so we must have

-x\geq 0 \ \text{ ***multiply by -1, it changes the inequality, so*** } \\ \\\large \boxed{\sf \ \ x\leq0 \ \ }

So the domain of the graph is all real numbers less than or equal to 0.

For information, I attached the graph so that we can verify it.

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
