a marble travel 300 cm in 6 seconds on the roller coaster what is the marble speed
Answer:
50
Step-by-step explanation:
Answer: 50 cm/s
Step-by-step explanation:
The formula for speed is: s=d/t
s=speedd=distancet=time----------------------------------------------------------------------------
Given
d=300 cm
t=6 s
Solve
s=d/t
s=(300)/(6)
s=50 cm/s
Hope this helps!! :)

Jamal has $15.00 to spend at the concession stand. He buys nachos for $7.50, and he wants to purchase some sour straws for $1.50 each. How many sour straws can Jamal purchase with the money that he has? (With x and you have to find the x)
Answer:
5
Step-by-step explanation:
Equation: 7.5 + 1.5x = 15
Subtract 7.5 from both sides you get 1.5x = 7.5
Divide both sides by 1.5 you get 5.
He can buy a total of 5 sour straws.
Hope this helps :)
Determine whether the following function is a one-to-one function. If it is one-to-one, list the inverse function by switching coordinates, or inputs and outputs. f={(9,7), (7,9), (6,7)} (1 point) The function f is not a one-to-one function. The function is one-to-one. The inverse is f−1={(−9,7), (−7,9), (−6,7)}. The function is one-to-one. The inverse is f−1={(−7,−9), (−9,−7), (−7,−6)}. The function is one-to-one. The inverse is f−1={(7,9), (9,7), (7,6)}.
Answer: An easy way to determine whether a function is a one-to-one function is to use the horizontal line test on the graph of the function. To do this, draw horizontal lines through the graph. If any horizontal line intersects the graph more than once, then the graph does not represent a one-to-one function.
i dont know the exact answer but its a lil sum
Step-by-step explanation:
We know that for any two inverses f(x) = g(y), meaning that if we take f(x) for any x in the domain of f(x), then g(y), where y is the outcome of f(x), should output x. So that is a simple test to see if two functions are inverses.
Consider the following equation
3x + 9y = 8y - 2
Step 2 of 2: Find the equation of the line which passes through the point (13,5) and is perpendicular to the given line. Express your answer in
slope-intercept form. Simplify your answer.
Answer:
The perpendicular line is:
y = 1/3 x + 2/3
Step-by-step explanation:
The given equation can be reduced to its slope-intercept form as shown below:
3x + 9y = 8y - 2
subtract 8 y from both sides
3 x + y = -2
subtract 3 x from both sides
y = - 3 x -2
therefore we know that the slope of this line is -3, and then, a perpendicular line to it must have slope given by the "opposite of the reciprocal" of this slope. That is, the slope of any perpendicular line to this one must be: 1/3
We use this slope to find the equation of the line passing through the point (13. 5)
y = 1/3 x + b
passing through (13, 5) means:
5 = 1/3 (13) + b
therefore, we can find b from the above equation
b = 5 - 13/3 = 15/3 - 13/3 = 2/3
Then the equation of this perpendicular line is:
y = 1/3 x + 2/3

Answer:
0.00446
Step-by-step explanation:
We need to find the value of the following expression :
[tex]\dfrac{(\dfrac{95}{17})^{-3}}{(\dfrac{15}{17})^{-2}}[/tex]
We know that, [tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]
So,
[tex]\dfrac{(\dfrac{95}{17})^{-3}}{(\dfrac{15}{17})^{-2}}=(\dfrac{95}{17})^{-3}\times (\dfrac{17}{15})^2\\\\=0.00446[/tex]
So, the value of the given expression is 0.00446.

Alia buys a computer. The original price of the
computer is $379.99. She uses a coupon for 15%
off any item. She must pay 6.75% sales tax on the
sale price. How much money will Alia spend on the
computer? (Hint....tax goes on the sales price!)
Answer:
$344.79
Step-by-step explanation:
379.99 decrease 15% =
379.99 × (1 - 15%) = 379.99 × (1 - 0.15) = 322.9915
322.9915 increase 6.75% =
322.9915 × (1 + 6.75%) = 322.9915 × (1 + 0.0675) = 344.79342625

what is the value of x ?
Enter your answer in the box . ° ?
Answer:
307°
Step-by-step explanation:
The sum of all the angles of a hexagon is equal to 900°.
So,
112+x+120+100+128+133 = 900
593+x = 900
x = 900-593
x = 307°
So, the value of x is equal to 307°.
