joshua swims 25 meters in 1 minute.Draw a graph of meters swam versus time.Find the value of the slope and interpret it in words
Answer:
Given,
The number of meters covered by Joshua in 1 minute = 25 meters,
So, the number of meters covered by him/her in x minutes, ( say y ) = 25x minutes,
⇒ y = 25x,
Which is the equation of line passes through origin,
If x = 1, y = 25,
If x = 2, y = 50,
So, by joining the points (1, 25) and (2,50) we will get the graph,
∵ Slope of a line y = mx + c is m,
By comparing,
The slope of the above line is 25 that shows the rate of change in meters per minute.
Note : x ≥ 0, because number of minutes can not be negative.

What is unitary Method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Lori had $126.89 in her bank account.
She deposited $21.49 into it and then wrote a check for her car repairs for $156.61.
After deposit her balance would be
=126.89 + 21.49
=148.38
and, the balance after paying for the repair
=148.38 - 156.61
=$ (-8.23)

Convert to the given unit. 40 m to cm A. 0.4 cm B. 4 cm C. 400 cm D. 4000 cm
Final answer:
To convert 40 meters to centimeters, multiply by 100, since there are 100 centimeters in a meter. The result is 4000 centimeters.
Explanation:
To convert 40 meters to centimeters, we need to determine the correct conversion factor between meters and centimeters. Since we are going from a larger unit to a smaller unit, we will multiply.
There are 100 centimeters in one meter, so we use this as our conversion factor.
The conversion is as follows:
40 m × 100 cm/m = 4000 cmTherefore, 40 meters is equal to 4000 centimeters.

Which are solutions to y=x-4? Choose all correct answers. (4,0), (3,-1), (6,3), (2,-4)
The coordinates (4, 0) and (3, -1) represents the solution of the function f(x).
We have a function -
y = f(x) = x - 4
We have to identify the possible solutions of this function from the ones mentioned.
What do you understand by the Solution of a function -y = f(x)?The solution of the function is the possible values of x (say a) for which f(a) equals to y.
According to the question -
y = f(x) = x - 4
Case 1 : P(4, 0)
0 = 4 - 4 = 0
P(4, 0) represents a solution
Case 2 : P(3, -1)
-1 = 3 - 4 = -1
P(3, -1) represents a solution
Case 3 : P(6, 3)
3 = 6 - 4 ≠ 2
P(6, 3) does not represents a solution
Case 4 : P(2, -4)
-4 = 2 - 4 ≠ -2
P(2, -4) does not represents a solution
Hence, the coordinates (4, 0) and (3, -1) represents the solution of the function f(x).

writing an inequality for x that would give this rectangle a perimeter of at least 300 ft.
Length: 3ft
width formula: x+5ft
please show steps!
Answer:
142≤ x.
Step-by-step explanation:
Given : rectangle a perimeter of at least 300 ft and Length: 3ft and width formula: x+5ft.
To find : Writing an inequality for x that would give this rectangle a perimeter.
Solution : We have given length = 3 ft.
Width = x + 5 ft .
Perimeter = 300 feet .
Perimeter = 2 ( length + width ) .
Plugging the values and greater than equal to sign for at least.
300 ≤ 2( 3 + x +5).
300≤ 2( 8 +x) .
300≤ 16 + 2x
On subtracting both sides by 16.
300 -16 ≤ 2x .
284 ≤ 2x.
On dividing both sides by 2.
142≤ x.
We can say x is at least 142.
Therefore, 142≤ x.

On the album 1989 by Taylor swift, Blank space is 12 seconds longer than shake it off. If the combined time of the two songs is 7 minutes and 30 seconds, how long is Shake It Off? Give your answer in minutes and seconds.
Answer:
Givens:
Blank Space is 12 sec longer than Shake It Off.The duration combined is 7 minutes and 30 seconds, which is 420 seconds.Lest's call [tex]B[/tex] Blank Space and [tex]S[/tex] Shake it Off, the relations would be
[tex]B=12+S\\B+S=420[/tex]
Now, we replace the first equation into the second equation and solve for [tex]S[/tex]:
[tex]12+S+S=420\\2S=420-12\\2S=408\\S=\frac{408}{2}=204[/tex]
Then, we replace this value into the first equation
[tex]B=12+S\\B=12+204=216[/tex]
This means that Shake It Off is 204 seconds long and Blank Space is 216 seconds long.
Therefore, if we express in minutes and seconds, we would have:[tex]204sec\frac{1min}{60sec}=3.4min=3 \ min \ and \ 24 sec[/tex]
[tex]216sec\frac{1min}{60sec}=3.6 min=3 \ min \ and \ 36 sec[/tex]
