A rental truck costs $96 per day plus $0.60 per each mile. If Calvin can spend a maximum of $120, how many miles can he drive th
1 answer:
Cost of renting a truck for one day = $96
Money Calvin can spend = $120
Money left with Calvin after he spends on the daily rent :
Cost charged per mile = 0.60
Number of miles he can drive the rental truck :
Thus, number of miles he can run the truck = 40 miles
Therefore, Calvin can run the truck for 40 miles after he pays the daily fee.

Answer:
$0.54
Step-by-step explanation:
Given:
The jars of peanut butter that I buy cost $7.20 each and normally contain 500 grams.
At present, however, each jar contains an extra 20% free.
And additionally, the supermarket has a "buy 3 jars get another one free''.
Question asked:
By how much is the cost per 100 grams of peanut butter less than it normally is if I take full advantage of the supermarket's offer today?
Solution:
Cost of a jars of peanut = $7.20
Normally, weight of peanut butter in one packet = 500 gram
At supermarket offer, each jar contains an extra 20% free, means a packet of peanut butter contains = 500 + 20% of 500
And extra benefit = buy 3 jars get another one free, means we will get 4 jars by just giving price of only 3 jars.
That means, total weight of peanut butter you are getting by giving 3 packet's price = Each jar weigh number of jars
= 600 4 = 2400 gram
<u>Cost of each packet will be same as previously as during the offer;</u> $7.20
Cost of 3 packet's peanut (2400 gram) =
Now, we will calculate cost per 100 grams of peanut butter :
<u>During offer:</u>
Cost of 2400 grams of peanut butter = $21.6
Cost of 1 gram of peanut butter =
Cost of 100 gram of peanut butter =
<u>Normal day:</u>
Cost of 500 grams of peanut butter = $7.20
Cost of 1 gram of peanut butter =
Cost of 100 gram of peanut butter =
We found that cost of 100 gram of peanut butter in normal day is $1.44 while cost of 100 gram of peanut butter during offer is $0.9 means cost per 100 gram during offer is ($1.44 - $0.9 = )$0.54 less than cost during normal day.
<u>Conclusion:</u>
Therefore, cost per 100 grams of peanut butter is $0.54 less than it is normally if you take full advantage of the supermarket's offer today.
Answer:
a = 21
b = 63
c = 42√3
d = 21√3
Step-by-step explanation:
The sides of a 30°-60°-90° triangle have the ratios 1 : √3 : 2. The given side (42) is the longest side of the smallest triangle, and the shortest side of the largest triangle.
That means the other sides of the smallest triangle will be ...
a = 42/2 = 21
a+b = 2(42) = 84
b = (a+b) -a = 84 -21 = 63
d = 21√3 . . . . middle-length side of the smallest triangle
c = 42√3 . . . . middle-length side of the largest triangle
The values of the variables are ...
- a = 21
- b = 63
- c = 42√3
- d = 21√3
