airplane a traveled 1273 miles in four hours.For airplane b y=621 x/2 represents rate of speed over the same four hours wichair plane traveled at a faster rate and by what factor?round to the nearest hundredth
Answer: Airplane A by a scale factor of 1.02
Step-by-step explanation:
Airplane A: 1273/4=318.25
Airplane B: Rate is the slope of equation, 621/2=310.5
So,
318.25/310.5=1.0249
Airplane 'a' is faster than airplane 'b' by a factor of 1.03 times.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, An airplane 'a' traveled 1273 miles in four hours.
∴ The airplane 'a' traveled (1273/4) = 318.25 miles per hour.
For airplane b y = (621x)/2 + 0b represents the rate of speed over the same four hours
∴ The rate of change per hour for airplane 'b' is (621/2) = 310.5 miles.
So, airplane 'b' is faster than airplane 'a' by a factor of (318/25/310.5) = 1.0257 = 1.03 times.

Wyatt is going to a carnival that has games and rides. Each game costs $1.25 and each ride costs $2.75. Wyatt spent $20.25 altogether at the carnival and the number of rides he went on is twice the number of games he played. Determine the number of games Wyatt played and the number of rides Wyatt went on.
Answer:
Wyatt played 3 games and went on 6 Rides
Step-by-step explanation:
Let games be represented as x
Let ride be represented as y
Each game cost $1.25
Each ride cost $2.75
Total money spent by Wyatt= $20.25
x1.25 + y2.75 = 20.25 ..... Equation 1
the number of rides he went on is twice the number of games he played
Y= 2x ... Equation 2
Substituting the value of y into equation 1
x1.25 + y2.75 = 20.25
x1.25 + 2(x)2.75 = 20.25
x1.25 + x5.5 = 20.25
x6.75= 20.25
x= 20.25/6.75
X= 3
Y= 2x
Y= 2(3)
Y= 6
Wyatt played 3 games and went on 6 Rides
Midpoint (24,-20), endpoint (16,-17)
Answer:
Endpoint = (32,-23)
Step-by-step explanation:
end point = (16,-17)
midpoint = 24,-20)
other point = (x,y)
(x + 16)/2 = 24
x + 16 = 24 * 2
x + 16 = 48
x + 16-16 = 48-16
x = 32

Marcelle claims that both these functions have the same discriminant.
Do you agree with Marcelle?
If you do, what is the value
of the discriminant?
If you disagree, explain why?
Answer:
Yes because they both only have one zero so the discriminant for both is 0
Step-by-step explanation:
explanation above lol
The two functions have the same discriminant b² - 4a = 0.
What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as its degree is two.
We know, Discriminant in a quadratic equation ax² + bx + c is, b² - 4ac.
Now, From the graph the discriminant and properties here,
D = 0 as the vertex of the parabola intersect only at one point.
b² - 4ac = 0.
The blue graph intersects at (2, 0) and the red graph intersects at (- 2, 0).
So, they have the same discriminant.

so multiply pizza by three too
to get 93
Answer:
93 students
