Answer:
25.2
Step-by-step explanation:
6/5 is 1.2, so it takes 1.2 minutes to run one lap.
This means 21 x 1.2 = the minutes it takes to run 21 laps around the track.
Therefore it takes 25.2 minutes to run around the track 21 times.

A new arcade opened up in town. A play package is available to purchase. It includes 15 tokens for games,plus 5 dollars off. Let x represent the cost per token
Answer:
The total cost of the games (play package)
= 15x - 5
Step-by-step explanation:
Number of tokens in the games = 15
The cost per token = x
Discount off the total cost = $5
Therefore, the cost of the play package = 15x - 5
where x is in dollars
However, ‘x’ can also assume any value.
Check:
If x = $15
The total cost of the game can be said to be 15(10) - 5 = $220

The graph of equation y = - 2x - 1 and the y-intercept (0, - 1) is shown in image.
We have to given that,
To plot the equation y = - 2x - 1 and the y-intercept on the graph.
Since, The equation of line in slope intercept form is,
y = mx + c
Where, m is slope and c in y - intercept.
Here, Equation is,
y = - 2x - 1
After comparing,
y - intercept = - 1
So, y - intercept of equation (0, - 1)

The question implies the two angles are equal because of the positioning of the named vertices. m∠A = m∠E so to say.
You can substitute the values and solve the inequality to find x, then solve for m∠A.
m∠A = m∠E; Given (Inferred)
6x - 8 = 4x + 1; Substitution
6x = 4x + 9; Addition Property of Equality

Write a multiplication equation that represents the question: how many 38s are in 54? DO NOT tell me the answer just show me how you worked it out using MULTIPLICATION. Thanks.
Answer:
[tex]38 x = 54[/tex]
Step-by-step explanation:
Required
Determine the number of 38 in 54
We start by representing the number of 38 in 54 with x
To determine the number of 38 in 54, we have to represented it as thus:
[tex]38 * x = 54[/tex]
Simplify the expression as follows:
[tex]38 x = 54[/tex]
The expression can be left like that or simplified further by dividing through by 2:
[tex]19x = 27[/tex]
Hence, the solution to the question is:
[tex]19x = 27[/tex] or [tex]38 x = 54[/tex]

In a certain country the fines for speeding in a school zone are $160 plus an additional $4 for every mile per hour over the speed limit. A. Write a function to represent the speeding fines
Answer:
T= 160 + 4x
Step-by-step explanation:
Giving the following information:
The $160 fine is a fixed cost. It will remain constant.
The $4 additional fine acts as a variable cost. It varies with the number of miles per hour.
To calculate the total cost (T), we need to use the following formula:
T= 160 + 4x
x= miles per hour exceeding the speed limit.

The period of a pendulum is the time the pendulum takes to swing back and forth. The function relates the length L= 0.81t in feet of a pendulum to the time t in seconds that it takes to swing back and forth. A convention center has a pendulum that is 90 feet long. Find the period.
Answer: 111.11 seconds
Step-by-step explanation:
Given: The period of a pendulum is the time the pendulum takes to swing back and forth
The function relates the length [tex]L= 0.81t[/tex] in feet of a pendulum to the time t in seconds that it takes to swing back and forth.
If L= 90 feet then put this in the above function, we get
[tex]90=0.81t\\\\\Rightarrow\ t=\dfrac{90}{0.81}\\\\\Rightarrow\ t=111.1111111\approx111.11\text{ seconds}[/tex]
Hence, the period = 111.11 seconds

The value of sin(2x) is [tex]\sin(2x) = - \frac{\sqrt{15}}{8}[/tex]
How to determine the value of sin(2x)The cosine ratio is given as:
[tex]\cos(x) = -\frac 14[/tex]
Calculate sine(x) using the following identity equation
[tex]\sin^2(x) + \cos^2(x) = 1[/tex]
So we have:
[tex]\sin^2(x) + (1/4)^2 = 1[/tex]
[tex]\sin^2(x) + 1/16= 1[/tex]
Subtract 1/16 from both sides
[tex]\sin^2(x) = 15/16[/tex]
Take the square root of both sides
[tex]\sin(x) = \pm \sqrt{15/16[/tex]
Given that
tan(x) < 0
It means that:
sin(x) < 0
So, we have:
[tex]\sin(x) = -\sqrt{15/16[/tex]
Simplify
[tex]\sin(x) = \sqrt{15}/4[/tex]
sin(2x) is then calculated as:
[tex]\sin(2x) = 2\sin(x)\cos(x)[/tex]
So, we have:
[tex]\sin(2x) = -2 * \frac{\sqrt{15}}{4} * \frac 14[/tex]
This gives
[tex]\sin(2x) = - \frac{\sqrt{15}}{8}[/tex]
