Answer:
The travel size costs 6 % as much as the regular size. Thus the regular size would be more economical and thus a better buy
Step-by-step explanation:
step 1
<em>Find out the unit rate of a regular tube of toothpaste</em>
we know that
To find out the unit rate, divide the total cost by the total weight
so

step 2
<em>Find out the unit rate of a travel size tube of toothpaste</em>
we know that
To find out the unit rate, divide the total cost by the total weight
so

step 3
Find out the percent of increase
we have that
The unit rate
represent the 100%
so by proportion
Find out what percentage represent the difference ($0.83-$0.78=$0.05 per ounce)

therefore
The travel size costs 6 % as much as the regular size. Thus the regular size would be more economical and thus a better buy
Using cosine law.
b= sqrt(38^2 + 18^2 - 2(38)(18) Cos 36)
using calculator solve.
b = sqrt (1444 + 324 - 1106.75)
b = 25.75
Answer:16

8+8=16
Answer:
x = 3
Step-by-step explanation:
1. 5x = 11 +4 (when the negative is moved, it turns positive)
2. 5x = 15
3. divide 15 by 5 and then you get your answer
The perimeter is 7500 yd because u multiple 50 by 300 to get 15,000 then divide that by 2 to get 7,500
