The highest elevation in California is 14,494 feet, on Mount Whitney. The lowest elevation in California is -282 feet in Death Valley. Find the RANGE of elevation in California.

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:

The cow has a greater heart rate than the horse.

Step-by-step explanation:

The question demand we calculate the heart beat of each animal in relation to time . The number of heart beat per unit time can be computed as follows .

The horse heart rate is 440 heart beat in 10 minutes . The heart rate can be simplified as  

Rate = 440/10

Rate = 44 heart beat per minute

The cow heart rate can be simplified as

Rate = 390/6

Rate = 65 heart beat per minute

From the Heart rate calculated above the cow has a higher heart rate than the horse.
