A parachutist's speed during a free fall reaches 264 feet per second. What is this speed in meters per second? At this speed, how many meters will the parachutist fall during 10 seconds of free fall? In your computations, assume that 1 meter is equal to 3.3 feet. Do not round your answers.
Speed:
Distance fallen in 10 seconds:
Answer: They will fall 800 meters. And they are falling 80 meters per second.
Step-by-step explanation: You must first take 264 divided by 3.3 which equals 80, then multiply is by 10.
Total distance fallen in 10 seconds is given by the equation A = 800 meter
What is Speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the total distance fallen in 10 seconds be represented as A
Now , the value of A is
The parachutist's speed during free fall = 264 feet/second
Now , 1 meter = 3.3 feet
So , 1 feet = ( 1/3.3 ) meter
So , the value of 264 feet = 264 x ( 1/3.3 ) meter
On simplifying the equation , we get
The value of 264 feet/second = 80 meter/second
Now , the distance traveled by the parachutist every second = 80 meter
So , the distance traveled by the parachutist in 10 seconds = 10 x distance traveled by the parachutist every second
Substituting the values in the equation , we get
The distance traveled by the parachutist in 10 seconds A = 10 x 80
On simplifying the equation , we get
The distance traveled by the parachutist in 10 seconds A = 800 meter
Therefore , the value of A is 800 meter
Hence , the total distance is 800 meter

Tracy is saving to buy a new guitar that costs $253.77 (including tax). Tracy has saved $136.27, and she can save $23.50 each week.
Which equation could you use to find how long it will take to save for the guitar?
$253.77 + $136.27 = $23.50 w
$253.77 - w = $136.27 + $23.50
$136.27 + $23.50 w = $253.77
$23.50 w = $253.77

Sasha hasn’t won any of the 40 games she has played with her four friends so far. She wants to win at least 20%. How many does she need to win in a row to get 20%?
Answer:
10
Step-by-step explanation:
Given that Sasha has won 0 games in the 40 games she has played.
Let she needs to win x game in a row, so
Total game she played = 40 + x
The number of the game she won is x, which is 20% of the total game she played, so
x = 20% of (40+x)
[tex]\Rightarrow x = 0.2(40+x) \\\\\Rightarrow x = 8+0.2x \\\\\Rightarrow x-0.2x=8 \\\\\Rightarrow 0.8x = 8 \\\\\Rightarrow x = 8/0.8=10.[/tex]
Hence, she needs to win 10 games in a row.

system using substitution or elimination).
Letr represent
Let c represent
I
Answer:
Number of Roses sold = 132
Number of Candy Grams sold = 85
Step-by-step explanation:
Let the number of Roses sold = [tex]r[/tex]
Let the number of Candy Grams sold = [tex]c[/tex]
Cost of one Rose = $1.50
Cost of [tex]x[/tex] Roses = $1.50 [tex]r[/tex]
Cost of one Candy Gram = $2.00
Cost of [tex]y[/tex] Candy Grams = [tex]\$2.00 \times c[/tex]
Total number of Roses and Candy Grams sold = 217
i.e.
[tex]r+c=217 ..... (1)[/tex]
Total cost = $368
Writing equation as per question statement:
[tex]\$1.50r+\$2.00c=\$368 ..... (2)[/tex]
Using elimination method, let us eliminate [tex]y[/tex] of the two equations.
Multiplying equation (1) with 2 and subtracting equation (2) from it:
[tex]0.50r=2\times 217 - 368\\\Rightarrow 0.50r=434 - 368\\\Rightarrow 0.50r=66\\\Rightarrow r=132[/tex]
By equation (1):
[tex]c=217-132\\c=85[/tex]
So, the answer is:
Number of Roses sold = 132
Number of Candy Grams sold = 85

Free cookies Just answer this question! Elena solves the equation x^2=7x by dividing both sides by x to get 7. She says
the solution is 7. Lin solves the equation x^2=7 by rewriting the equation to get
x^2-7=0. When she graphs the equation x^2-7=0, the x-intercepts are (0,0) and
(7,0). She says the solutions are 0 and 7. Why should Elena not divide by x?
x could be equal to zero, and we can't divide by zero, so we shouldn't divide by x.
Why should Elena not divide by x?
Here we have the quadratic equation:
[tex]x^2 = 7x[/tex]
Notice that we don't know the value of x, so technically, x could be equal to zero, and we can't divide by zero, so we shouldn't divide by x.
The quadratic equation can be rewritten as:
x^2 - 7x = 0
x*(x - 7) = 0
(x - 0)*(x - 7) = 0
So the two solutions are x = 0 and x = 7, because x = 0 is a solution, we see that x can be equal to zero, so we can't divide by x.
