creativ13 [48]

Answer:

50 deciliters

Step-by-step explanation:

Given that,

Jennifer buys a 2-liter bottle of apple juice and a 3-liter bottle of orange juice at the market.

Total = 2 L bottle of apple juice + 3 L bottle of orange juice

= 5 L

We need to find how many deciliters of juice does Jennifer buy in all.

Since, 1 L = 10 Deciliter

5 L = 50 Deciliter

So, she will buy 50 deciliters of juice.

Raphael is traveling in a straight line at a constant speed from point A to point B. His distance from point B in miles is -20t+
Rudik [331]

Answer:

Speed  = 20 mi/h

Explanation:

There are two points A and B

Distance between both the points are define with function -20t + 45 miles

where t represent the number of hours of travelling.

Now firstly we find the initial position. At starting time is 0, so we put t=0 in given function of t.

At t=0;

d₀ = -20(0) + 45 = 0 + 45 = 45 miles

Now we find the distance travell after starting first hour.

Than we put t = 1 in the given function

At t = 1;

d₁ = -20(1) + 45 = -20 + 45 = 25 miles

Difference between d₁ & d₀ is

45 - 25 = 20 miles

We see that in one hour, total distace is covered 20 miles

Now we use time, speed, distance relation

Speed = distance/time

Speed= \frac{20}{1}

Speed = 20 miles/hour

That's the final answer.

I hope it will help you.
