Answer:
The number of small vehicles washed in total = 60
Step-by-step explanation:
Amount of money that soccer team selected at a car wash fundraiser = $800
Amount of money charged for small vehicles = $5
Amount of money charged for larger vehicles = $10
The amount collected can be modeled by the equation 5x + 10y = 800 , where x represents the number of small vehicles and y represents the number of larger vehicles
Now, the number of larger vehicles washed was 50 and we need to find the number of small vehicles washed.
So, y = 50 and find the value of x from the modeled equation
⇒ 5x + 10y = 800
⇒ 5x + 10 × 50 = 800
⇒ 5x + 500 = 800
⇒ 5x = 300
⇒ x = 60
Thus, The number of small vehicles washed in total = 60
An algebraic expression that can be used to represent the new y-coordinate after a translation of four yards south is y-4.
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Let's assume that 1 unit represents 1 mile.
Given that the present coordinate of the point is y. Now, if the point is moved towards the south, then the point will be shifted to 4 units sown. Therefore, we can write an algebraic expression to represent the new y-coordinate after a translation of four yards south as,
New-coordinate = y - 4
Hence, an algebraic expression that can be used to represent the new y-coordinate after a translation of four yards south is y-4.

Answer: y + (-4)
Step-by-step explanation:
A translation of four yards south involves moving 4 units in the negative y-direction. Given any initial y-coordinate, y, the algebraic expression that represents the y-coordinate after translation is y + (-4)
*edmentum answer*
B twice the force with which it was fired.
C one half the force with which it was fired.
D the same amount of force with which it was fired.
E one quarter the force with which it was fired.
Answer:
A zero, since no force is necessary to keep it moving
Step-by-step explanation:
Since, the space is friction less, the force exerted by the gun will be enough to keep the ball going. There will not be any depreciation in the initial force. Hence, the ball continues to move forward without any impediment.
Hence, the correct answer is
A zero, since no force is necessary to keep it moving
For a better understanding of the solution/explanation given here please go through the diagram in the file attached.
By definition, an angle bisector is a ray that divides an angle into two congruent angles.
In our question we have been given that GJ is the ray that is the angle bisector and that has been shown in the diagram.
Now, since, , therefore, the ray will divide the original angle into two congruent angles, and . Since, the division is equal, the values of both these angles will be half of the original angle. Thus, we will have:
Thus, the required value of
