A coin collection consists of dimes and nickels. If there are a total of 500 coins valued
at $39. how many dimes are there?

Answers

Answer:

There are 280 dimes

Step-by-step explanation:

A nickel is worth 5 cents while a dime is worth 10 cents

Let n be number of nickel

d the number of dimes

n + d = 39

Secondly

$39 is same as 3900 cents

So we have;

10d + 5n = 3900

From first equation;

n = 500-d

Put this in second equation;

10d + 5(500-d) = 3900

10d + 2500-5d = 3900

5d = 3900-2500

5d = 1400

d = 1400/5

d = 280

Find the slope and the y-intercept of the graph of the linear equation y=5/4x-7. The slope is ?, and the y-intercept is ?.

Answers

Answer:

Not Linear.

Step-by-step explanation:

Answer:

5/4 slope

-7 y intercept.

Step-by-step explanation:

The slope is the number in front of the x. The number in front of the x is 5/4. The slope is 5/4

1. The y intercept is whatever is behind the x or 0 if there is no number following the x.  

2. The y intercept is also characterized by being on the same side of the equation as the x.

3. Finally it has no x in it.

In this case the y intercept is -7

Examples

y + 2 = x    2 is not the y intercept. subtract 2 from both sides. y = x - 2. Therefore -2 is the y intercept.

2y = 4x + 6                4 is not the slope. You have to divide by y = 2x+3. So 2 is the slope and 0,3 is the y intercept.

Allan can make 8 pizzas in 15 minutes at the pizza restaurant where he works. 28. __________ If the number of pizzas varies directly with minutes, how many pizzas can Allan make in 3 hours?

Answers

Answer:

96 pizzas

Step-by-step explanation:

First, we have to determine how many pizza he can make in one minute = 8/15 = 0.533

Convert 3 hours to minutes = 3 x 60 = 180 minutes

The number of pizzas he would make in 3 hours = 180 x 0.533 = 96 pizzas

Two years ago, Jose bought $750 worth of stock in a cell phone company. Since then the value of his stock has been DECREASING at an average rate of 5 1/4 % per year. How much is the stock worth now?

Answers

Answer:

$671.25

Step-by-step explanation:

To get the amount by which the stock have reduced after 2 years, we will use the interest formula;

Interest = Principal * rate * time/100

Interest = 750*5 1/4 * 2/100

Interest = 750*21*2/400

Interest = $78.75

This means that the value of the stock has reduced by $78.75 after 2 years;

Amount that the stock worth now = $750 - $78.75

Amount that the stock worth now = $671.25
