Step-by-step explanation:
Keywords:
perimeter, square, base, pyramid, kilometers, side
For this case we must find the perimeter of the base of a square pyramid, whose side of the square measures 160m. In addition, the measure obtained must be converted to kilometers. So, we have by definition the perimeter of a square is the sum of its sides, which is equivalent to , where "l" is the side of the square.
If, then:
Thus, the perimeter of the base of the pyramid is 640m.
On the other hand, by definition:
By making a rule of three we have:
1Km ---------> 1000m
x --------------> 640m
Where "x" represents the perimeter of the base of the pyramid in Km.
Thus, the perimeter of the base of the pyramid is 0.64Km
Answer:
The perimeter in kilometers is 0.64
Answer:To determine if the relationship between the amount of vinegar and oil in the salad dressing is proportional, you can compare the ratio of vinegar to oil used by Manuela to the ratio called for in the recipe.
The recipe calls for 3 parts oil to 1 part vinegar. This means for every 3 tablespoons of oil, you should use 1 tablespoon of vinegar.
Manuela used 6 tablespoons of oil and 2 tablespoons of vinegar.
Now, let's compare the ratios:
Manuela's ratio of oil to vinegar: 6 tablespoons of oil to 2 tablespoons of vinegar, which can be simplified to 3:1.
The recipe's ratio of oil to vinegar: 3 parts oil to 1 part vinegar, which is also 3:1.
Since both ratios are 3:1, Manuela's use of oil and vinegar is in proportion to the recipe's instructions. Therefore, it is a proportional relationship.
Answer:
1.2 hours
Step-by-step explanation:
Given the following :
Time taken by Adam to shovel driveway = 2 hours
Time taken by BEV to shovel highway = 3 hours
How long will it take them working together
Hence Adam's rate of shoveling per hour :
Reciprocal of time taken = 1/2 per hour
BEV's rate will also be ;
1/ 3 per hour
If both work together ; that is combining the rate :
1/2 + 1/3 = (3 + 2) = 5/6
Combined rate = 5/6
Total fraction of shoveled area = 1:
Time taken = area / rate
= 1 ÷ (5/6)
= 1 × (6 / 5)
= 6/5
= 1 1/5 hours = 1.2 hours
To solve the problem, the concept of replacement must be considered.
A letter is randomly chosen from the bag and then replaced. Then, a second letter is randomly chosen from the bag.
The probability of the two vowels chosen is 25/144.
Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
Given
The Hawaiian language has 12 letters.
Five vowels and seven consonants.
To find
The probability of two vowels is chosen.
1. Probability of first letter being vowel.
Total event = 12
Favorable event = 5
Then
2. Probability of second letter being vowel.
Total event = 12
Favorable event = 5
Then
The probability of both occurring will be
Thus, The probability of the two vowels chosen is 25/144.
