Explanation:
An <em>explicit function</em> returns a value based only on the arguments given.
y = f(x)
__
A <em>recursive function</em> returns a value based on the arguments given and on other values of the function.
y = f(x, f(g(x))
Answer:
15 units
Step-by-step explanation:
If one side of a triangle is 5 units you multiply that by 3 (3 sides in a triangle)
= 15 units
Hope this helped :)
Since 10% = 0.10 by moving the decimal two spots to the left, we can say that 0.10L is the amount of alcohol with 10% concentration in L liters. Similarly, 0.60L is 60% for L liters and 0.30L is the amount of liters with 30%. If the amount of 10% alcohol solution in liters is x and the 60% in y, we get 0.10x+0.60y=0.30L due to that the liters add up to get a 30% amount of alcohol (this equation represents the amount of alcohol). Next, x+y=L. Since we know that we have 90 liters of 0.60, y=90 and we have
0.10x+54=0.30L
x+90=L. Plugging x+90 for L, we get 0.10x+54=0.3(x+90)=0.3x+27. Subtracting 27 and 0.1x from both sides, we get 0.2x=27. Next, we can multiply both sides by 5 (since 1/0.2=5) to get x=135 liters
Answer:
The number of baseball card to begin with is 143
Step-by-step explanation:
Let The number of baseball cards = x
The number of sold baseball card = 60% of x
= 0.6 x
The number of left baseball card = x - 0.6 x = 0.4 x
The number of card gave away = 30 % of left cards
= 0.3 × 0.4 x = 0.12 x
The number of card left in his possession = 40
So, 0.6 x + 0.12 x + 40 = x
Or, 40 = x - 0.6 x - 0.12 x
Or, 40 = 0.28 x
∴ x = 
= 142.85 ≈ 143
Hence The number of baseball card to begin with is 143 Answer
Answer:
45/50= 9/10
Step-by-step explanation:
If 5 packs were left after the sale, then 50-5=45 is the number of packs sold
Then the fraction sold would be the number of packs sold divided by the total number of packs.
45 sold/50 total
