Evgen [1.6K]3 years ago

Answer:

20 dimes and 2  quarters

Step-by-step explanation:

x = number of dimes

y  = number of quarters

minimum is greater than or equal to ≥

x+y ≥16

no more than is less than or equal to ≤ ,

value of dime is $ 0.10

value of quarter is $0.25 so

0.10x + 0.25y ≤ 3.00

Rewrite inequalities in terms of y:

y ≥16 - x

(0.25/0.25)y ≤ (3.00/0.25)-(0.10/0.25)x→

y≤12 - 0.4x

Is (-3, 2) a solution of -4r - 10y< - 9?
Blizzard [7]

Answer:

<em>The point (-3,2) is not a solution of the inequality</em>

Step-by-step explanation:

<u>Inequality</u>

Inequalities relate the left and the right side of an expression with an operator other than the equal sign.

The inequality given in the question is

-4r - 10y< - 9

There are many combinations of r and y that make inequality be true. For example, for r=1 and y=1

-4(1) - 10(1)< - 9

-14< - 9

This relation is true since -14 is less than -9.

Also, there are many combinations that make the given inequality be false.

For example, for r=2 and y=-1

-4(2) - 10(-1)< - 9

-8+10

2

This inequality is false.

Let's test the point (-3,2)

-4(-3) - 10(2)< - 9

12-10

2

Which is false, thus the point (-3,2) is not a solution of the inequality

If one of the pedestrian deaths is randomly selected, find the probability that the driver was not intoxicated. Please enter a d
Ivan

Using it's concept, it is found that there is a 0.8606 probability that the driver was not intoxicated.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

Researching the problem on the internet, it is found that there are 62 + 76 + 254 + 598 = 990 deaths, of which 254 + 598 = 852 did not involve an intoxicated driver, hence the probability is given by:

p = 852/990 = 0.8606

Mark just landed a great job as an engineer where he will make $65,000 a year. The company he will work for guarantees a 2% pay
dalvyx [7]

Answer:

65000(1.02)^n.

Step-by-step explanation:

Salary = 65000(1.02)^n   where n is the number of years he has worked for the company.

So after one year he earns $6500* 1.02 and after 2 years $65000 * 1.02^2.
