41 coins, consisting of nickels and quarters, have a total value of $4.65. How many coins of each kind are there?
aivan3 [116]

You first have to make an simple equation.

x = How many pennies

y = How many quarters

After that, since a penny is 5 Cents and a quarter is 25 Cents, we make the equation as:

5x + 25y = 465 (cents)

To write the whole entire thing in an equation is:

x + y = 41

y = 41 - x    Since I brought the x from the left to right, we change the positive "x" to negative "y"

To bring the 'y = 41 - x' to 5x + 25y = 465, we get rid of the "y"s from both equations.

Now, you are left with the simplified equation:

5x+25(41-x)=465\\

25*41+5x-20x=465

-20x+25*41=465

-20x=465-(25*41)

-20x=465-1025

-20x=-560

20x=560

x=28

Now you find the y.

x = 28

28+y=41\\41-28=y\\y=13

Conclude:

So the y was the quarter and the x was the pennies.

Quarters = 13

Pennies = 28

Mark all the statements that are true . A. This graph is a function whose domain is the set 3 B. This graph is a function becaus
nika2105 [10]

The statements that are true are

  • This graph is a function because the value of x is the same for every value of y
  • The equation of this line is x = 3. Options B and D

This is further explained below.

<h3>What are the statements?</h3>

Generally, A relation is considered to be a function if it can be shown that each value from the set of first components of ordered pairs is connected with precisely one value from the set of second components of ordered pairs.

In conclusion, You may also consider this in terms of the fact that there is one and only one y associated with each x.

Although it is obvious that this is not the case, the calculation for the vertical line nevertheless uses these terms.

A company that makes hair care products at 9000 people try a new shampoo. Of the 9000 people, 18 had a mid allergic reaction. Wh
lara [203]

Answer:

0.2% of the people had mid allergic reaction.

Step-by-step explanation:

Given that:

Number of people tested for a new shampoo = 9000

Number of people who had allergic reaction = 18

Percent of people = \frac{People\ who\ have\ reaction}{Total\ number}*100

Percent of people = \frac{18}{9000}*100

Percent of people = 0.002 * 100

Percent of people = 0.2%

Hence,

0.2% of the people had mid allergic reaction.
