Answer:
O weight in kilograms = 25 x 3.5 ÷ 2.2
Step-by-step explanation:
As a butcher, you sell beef in 3.5-pound packages. You anticipate needing 25 packages for the next two days.
Therefore, the total number of pounds for the 25 packages =
3.5 pound packages × 25
= 87.5 pounds
We are told that : The wholesaler from whom you purchase large pieces of meat measures the weight of the beef in kilograms.
Note that:
2.2 pounds = 1 kg
Hence:
87.5 pounds =
= 87.5÷ 2.2
= 39.772727273 kg
He needs to buy 39.772727273kg from the wholesaler
The equation can you use to determine the weight of the beef, in kilograms, that you need to purchase from the wholesaler is:
O weight in kilograms = (25 x 3.5) ÷ 2.2
The value of X is equal to 7
Answer:
4 / 5 = 8 / 10
Step-by-step explanation:
4:5 is a ratio which can be rewritten as 4/5.
Any number that is multiplied by both the 4 and the 5 is an equivalent ratio to 4:5.
For example, if we multiply 2 by both sides, we have 8 to 10 which is equal to 4 to 5.
1.Do you think a similar rule is true for cosine? That is, does -cos (θ) = cos (-θ)? Pick a value of θ and test this theory.
It is not the same.
To prove it, let's choose a value of the angle:
θ = 45 degrees:
-cos (θ) = cos (-θ)
-cos (45) = cos (-45)
- (root (2) / 2) = (root (2) / 2)
answer:
NOT fulfilled: -cos (θ) = cos (-θ) (false)
2. Using your example above, speculate on a rule that might be true for cos (-θ).
cos (θ) = cos (-θ)
To prove it, let's choose a value of the angle:
θ = 45 degrees:
cos (θ) = cos (-θ)
cos (45) = cos (-45)
(root (2) / 2) = (root (2) / 2)
answer
A rule for cosine can be:
cos (θ) = cos (-θ)
Using the arrangement formula, it is found that there are 
possible seating arrangements.
The number of possible arrangements of n elements is given by the <em>arrangement formula</em>, as follows:
- It is used when n elements are arranged in n positions.
In this problem, <u>28 students are arranged on 28 desks</u>, hence 
, and:
Hence, there are possible seating arrangements.
