Answer:
Let x be the number of albums to be bought and
let y be the number of movies to be bought.
The amount to be spent on albums is 10x and
The amount to be spent on movies is 30y.
As per the given condition: The total amout to be spent must equal $ 150.
then, we have
......[1]
Now, find x-intercepts and y-intercepts of equation [1];
x-intercepts defined as the graph crosses the x-axis.
Substitute y= 0 in [1] to solve for x;
10x =150
Divide both sides by 10 we get;
Simplify:
x = 15
y-intercepts defined as the graph crosses the y-axis.
Substitute value of x=0 in [1] to solve for y;
10(0)+30y = 150
30y =150
Divide both sides by 30 we get;
y =5
Now, plot these points (0, 5) and (15, 0) on graph and connect them with a line as shown in the figure below;
Answer:
x + 3y = 15
The graph is attached below.
Step-by-step explanation:
Given the price of album = $10.
and the price of movies = $30.
Let's assume she buys "X" albums and "Y" movies.
Cost would be (10X + 30Y).
She plans to spend a total of $150, so cost would be same as total expenditure.
10X + 30Y = 150
X + 3Y = 15
we can graph this equation of line on a graph paper as given below:-
The radius of the circle is 23 cm if the bicycle wheel has a diameter of 46 cm the answer is 23 cm.
It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
A bicycle wheel has a diameter of 46 cm
The bicycle wheel is in the shape of a circle.
The diameter of the circle D = 46 cm
As we know, the diameter of the circle is double the radius or the radius of the circle is half the diameter.
r = D/2
Here, r is the radius of the circle
D is the diameter of the circle.
r = 46/2
Divide by 2 on the numerator and denominator.
r = 23 cm
Thus, the radius of the circle is 23 cm if the bicycle wheel has a diameter of 46 cm the answer is 23 cm.
