Can I get help on number 7!!!!!
Ratling [72]

Answer:

C =(43/55)R; C - R = 8t; 48 mi  

Step-by-step explanation:

Let C = the distance a coyote can run in t hours.

Let R = the distance a rabbit can run in t hours.

(1) C = 43t

(2) R = 35t

A. <em>Two equivalent expressions </em>

(a)   C/R = 43/35

           C = (43/55)R

(b) C – R = 43t – 35t

    C – R  = 8t

B. <em>Distance advantage of coyote </em>

Let the difference D = C - R

D = 8t

D = 8 × 6

D = 48 mi

In 6 h, the coyote can run 48 mi further than the rabbit.

What is 25% of 400 5% of 20
stiks02 [169]

Hello there!


What is 25% of 400?

\frac{25*400}{100}

= \frac{10,000}{100}

= 100

Thus,

25% of 400 is 100


What is 5% of 20?

Well, we just need to follow the previous steps.

\frac{5*20}{100}

= \frac{100}{100} = 1

Thus,

5% of 20 is 1


I hope this answer helps. Let me know if you have additional questions about the answer. As always, it is my pleasure helping student like you.
