A circular swimming pool is 21 feet in diameter. What is the circumference of the swimming pool? Use 22/7 for pie

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:-

Answer:

95

Step-by-step explanation:

To round 95.131 to the nearest whole number consider the tenths’ value of 95.131, which is 1 and less than 5. Therefore, we have to round down: the whole number ones place value of 95.131, 95, remains 95, and the decimal point and all digits (.131) are removed.

95.131 rounded to the nearest whole number = 95

Answer:

95.13 !

Explanation:

Its 131 so its 1 away from 130, which is the closest hundredth. Also, we don't really need the 0, so its 95.13, instead of 95.130!
