Question:
Because of a problem in the program, the timer in a video player did not begin counting until the video had been playing for several seconds. The player began counting at 0 seconds, even though the video had already played 190 frames. The video plays 25 frames per second.
How many frames had the video already played when the time was equal to [tex]3\dfrac{2}{5}[/tex]
Answer:
275 frames
Step-by-step explanation:
Given
[tex]Start\ time = 0s[/tex]
[tex]Rate =25frames/sec[/tex]
[tex]Played = 190\ frames[/tex]
Required
Number of frames played when [tex]time = 3\frac{2}{5}[/tex]
First, calculate the time taken to play 190 frames
[tex]Time = \frac{Frames}{Rate}[/tex]
[tex]Time = \frac{190}{25}[/tex]
[tex]Time = 7\frac{3}{5}[/tex]
So, when the time is at: [tex]3\frac{2}{5}[/tex]
The total time is:
[tex]Total = 7\frac{3}{5} + 3\frac{2}{5} -0[/tex]
[tex]Total =\frac{38}{5} + \frac{17}{5}[/tex]
Take LCM
[tex]Total =\frac{38+17}{5}[/tex]
[tex]Total =\frac{55}{5}[/tex]
[tex]Total =11s[/tex]
The number of frames is then calculated as:
[tex]Frames = Rate * Time[/tex]
[tex]Frames = 25 * 11[/tex]
[tex]Frames = 275[/tex]

Theo is an atletic trainer who works with high school football and baseball players of his clients 40% play football and the rest play baseball. Of the students who play football 30% are on the varsity team while 50% of theo's baseball clients are on the varsity team. What percent of theo's clients are on the varsity team
Answer:
42%
Step-by-step explanation:
For the Theo's clients, 40% play football. That means the 60% is playing baseball.
Of the 40% that play football, only the 30% are on the varsity team, that is:
40% * 30% = 12% of the Theo's clients are on the Varsity team of football
And of the 60% that play baseball, the 50% are in the varsity team, that is:
60% * 50% = 30% of the Theo's clients are on the varsity team of baseball.
The percent of theo's clients on the varsity team is:
12% + 30% =

A family buys 6 airline tickets online. The family buys travel insurance that costs
total cost is $1,014. Let x represent the price of one ticket. Write an equation for t
find the price of one ticket.
Answer:
6x + 102 = 1,140
Step-by-step explanation:
We're looking for the sum. The insurance cost 17 dollars per ticket, and there are 6 tickets, so we have to multiply. 17 times 6 is 102. Next, we subtract 102 from both sides. 6x = 1,038. Then, divide by 6. x = 173. So, one ticket costs 173. I don't know if the insurance is included, but if it is, then add 17 and you get 190.

A rectangle with a length of x + 5 has a perimeter of 4x + 14.
1. Write the expression for the width of the rectangle in terms of x.
2. Suppose the perimeter of the rectangle is 42 inches. What are the length and
width of the rectangle?
3. Write the expression for the area of the rectangle in terms of x.
4. What is the area of the rectangle when x = 7?
Show how t get the answer
Answer:
1. Width = x + 2
2. Length = 12; width = 9
3. x² + 7x + 10
4. 108
Step-by-step explanation:
perimeter = 4x + 14
length = x + 5
1. Perimeter of a rectangle = 2(length + width)
4x + 14 = 2{(x + 5) + width}
4x + 14 = 2x + 10 + 2width
4x + 14 - 2x - 10 = 2width
2x + 4 = 2width
Width = (2x + 4)/2
Width = x + 2
2. Perimeter of a rectangle = 2(length + width)
42 = 2{(x + 5) + (x + 2)}
42 = 2x + 10 + 2x + 4
42 = 4x + 14
42 - 14 = 4x
28 = 4x
x = 28/4
x = 7
length = x + 5
= 7 + 5
= 12
Width = x + 2
= 7 + 2
= 9
3. Area of the rectangle = length × width
= (x + 5)(x + 2)
= x² + 2x + 5x + 10
= x² + 7x + 10
4. Area of the rectangle = x² + 7x + 10
When x = 7
x² + 7x + 10
= 7² + 7(7) + 10
= 49 + 49 + 10
= 108

Each side of a square classroom is 8 yards long. The school wants to replace the carpet in the classroom with new carpet that costs $79.38 per square yard. How much will the new carpet cost?
Answer:
Total cost= $4,445.28
Step-by-step explanation:
Giving the following formula:
Each side of a square classroom is 8 yards long.
The new carpet costs $79.38 per square yard.
First, we need to calculate the total number of square yards needed:
Square yards of the classrom= 8*8= 56
Now, the total cost:
Total cost= total square yards*unitary cost
Total cost= 56*79.38
Total cost= $4,445.28

Han's garden has an area of 193.75
square feet. If the length of the garden
is 12.5 feet, what is the width
Answer:
15.5
Step-by-step explanation:
The equation to find area is Length × Width= Area
we have the area and the length, 12.5 × width= 293.75
to find the width, you will have to reverse engineer and divide the area by the length instead.
193.75 ÷ 12.5 =15.5
just to double check, 15.5 × 12.5 = 193.75
the width is 15.5
A system of equations is shown below. y=-x+3 y=3-/2 Does the ordered pair (-4, 6) satisfy the system? Justify your answer.
Answer:
(2.5, 5.5)
Step-by-step explanation:
The system of equation is not well written
Let the system of equations be;
y = x+3
y = 3x - 2
Equate both expressions to get x;
x + 3 = 3x - 2
x - 3x = -2-3
-2x = -5
x = 5/2
x = 2.5
Get the value of y;
y = x+3
y = 2.5+3
y = 5.5
Hence the required coordinate point is (2.5, 5.5)
Note that the second equation was assumed but the same steps can be taken to solve the given equation

A caterer is preparing a dinner for a party. Shecharges an initial fee of $16 and $8.25 per person. How manypeople can attend a dinner that costs $131. 50? Write an equationand solve.
Answer:
The nomber of people can attend a dinner that costs $131. 50 is 14.
Step-by-step explanation:
With the information provided, it can be said that the total cost of a dinner would be equal to the initial fee plus the result of multiplying the price per person for the number of people, which can be expressed as:
c=16+8.25x, where:
c is the total cost of he dinner
x is the number of people
Now, you can replace c with 131.50 that is the cost of a dinner and solve for x to find the number of people that can attend:
131.50=16+8.25x
131.50-16=8.25x
115.50=8.25x
x=115.50/8.25
x=14
According to this, the answer is that the nomber of people can attend a dinner that costs $131.50 is 14.
