Answer:
[tex]160\ \text{s}[/tex]
Step-by-step explanation:
The inequality that represents the situation is
[tex]500-2.5t<100[/tex] where [tex]t[/tex] is the time in seconds
[tex]\Rightarrow -2.5t<100-500[/tex]
[tex]\Rightarrow -2.5t<-400[/tex]
[tex]\Rightarrow 2.5t>400[/tex]
[tex]\Rightarrow t>\dfrac{400}{2.5}[/tex]
[tex]\Rightarrow t>160\ \text{s}[/tex]
So, the time after which there will be less than 100 gallons of water is [tex]160\ \text{s}[/tex].
Determine the length of AC and DE, and the value of x.
Answer:
n = 16, AC = 60, DE = 30
Step-by-step explanation:
DE joins the midpoints of 2 sides of the triangle and is half the length of the third side, that is
DE = [tex]\frac{1}{2}[/tex] AC , substitute values
n + 14 = [tex]\frac{1}{2}[/tex] (3n + 12) ← multiply both sides by 2 to clear the fraction
2n + 28 = 3n + 12 ( subtract 2n from both sides )
28 = n + 12 ( subtract 12 from both sides )
16 = n
Then
AC = 3n + 12 = 3(16) + 12 = 48 + 12 = 60
DE = n + 14 = 16 + 14 = 30

At a carnival booth, customers had to guess the number of jelly beans in a jar. Samantha guessed there were 375 jelly beans. The actual amount of jelly beans in the jar was 250. What is Samantha's percent error?
Answer:
150
Step-by-step explanation:
The required percent error by Samantha is 50%, as of the given condition,
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
What is the error?Errors are discrepancies between values that are seen and natural truths.
Here,
Samantha guessed there were 375 jelly beans.
The actual amount of jelly beans in the jar was 250.
Error percentage = 375-250 / 250 × 100
= 0.5 × 100
= 50%
Thus, the required percent error by Samantha is 50%, as of the given condition.

Answer:

Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationships between sides and trig functions. The relevant relations here are ...
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
In your diagram, leg 'a' is opposite angle α and adjacent to angle β. Similarly, leg 'b' is opposite angle β and adjacent to angle α. The hypotenuse is 'c' in all cases.
So, filling the table is a matter of identifying adjacent and opposite legs. You will notice that the sine of α is the cosine of β and vice versa.

If sin y° = 9/c and tan y° = 9/d, what is the value of cos y°?
Answer:
d/cStep-by-step explanation:
Given:
sin y° = 9/c and tan y° = 9/dWe know that
tan α = sin α /cos α ⇒ cos α = sin α / tan αSolving for cos y°, by substituting values:
cos y° = sin y° / tan y° cos y° = 9/c ÷ 9/d = 9/c × d/9 = d/cAnswer:
the answer to your question is d/c
