So I was ordering me food that cost $16.13. And I have $15 and 4 quarters, 1 dime and 5 pennies. How can I make it work? Can I use the extra dollar with the 4 quarters so that I have $16?

Answers

Yes that would work since 4 quarters equals a dollar, 1 dime is equal to 10 cents and 5 pennies is equal to 5 cents and all of those added up is equal to $16.15, so you would have 2 cents in change.

Answer:

Technically, it already works because you have $16.15

Step-by-step explanation:

Let A be the event that there are at least two fives among the four rolls. Let B be the event that there is at most one five among the four rolls. Find the probabilities P(A) and P(B) by finding the ratio of the number of favorable outcomes to the total (i.e., P(A) = #A #Ω and P(B) = #B #Ω ).

Answers

Answer:

P(A) = 31/1296

P(B) = 125/1296

Step-by-step explanation:

Here, we want to find P(A) and P(B)

Let’s start with A

In a roll of a die, the probability that there will be a 5 is 1/6

The probability of not having a 5 is therefore 1-1/6 = 5/6

So out of four rolls , we want to find the probability of having at least two fives

This means there could be 2, 3 or 4 fives;

For two fives;

We have 2 fives and two non-fives

= (1/6 * 1/6 * 5/6 * 5/6) = 25/1296

For 3 fives;

we have 3 fives and 1 non five

= 1/6 * 1/6 * 1/6 * 5/6 = 5/1296

For 4 fives;

= 1/6 * 1/6 * 1/6 * 1/6 = 1/1296

So the probability of at least two fives is;

1/1296 + 5/1296 + 25/1296 = 31/1296

Event B is the probability that there is at most one five among the four rolls

That means there are 3 non fives and 1 five

P(B) = 1/6 * 5/6 * 5/6 * 5/6 = 125/1296

The expression are

        [tex]\Delta E  = \Delta E _1 + \Delta E_2[/tex]

and

     [tex]\Delta E  = \Delta E _3 + \Delta E_4[/tex]

Step-by-step explanation:

Generally from the diagram  the energy change from state A to  state B is  

        [tex].\  \ \Delta E_2 \ \ \ \ \  \  \ \ \Delta E_2  \\A  \ \ \to \ \ \  C \ \ \ \to \ \ \  B\\[/tex]

Your weld settings are 17.5 volts and 125 amps. use ohm's law to count how much resistance is in your welding circuit.

Answers

Answer:

0.14 ohms

Step-by-step explanation:

We know that ohms law is given by the expression

V=IR

In the problem, we are given that

voltage v= 17.5volts

currents I=125 amps

Substituting our data into the expression we have

17.5=125*R

R=17.5/125

R=0.14 ohms

Hence the current is 0.14 ohms

I don't understand why the answer is y=3x+1.
I got y =3x-6
please help me.​

Answers

Answer: Answer is y= 3x+1

Step-by-step explanation:

Use point slope form y-y°=m(x-x°)

Find m, the slope: subtract the y values of the points, and divide that with the number you get when you subtract the x values of the points.

You should get m=3

Take either of the points, I’ll choose (0,1) because they are easy to use. Substitute 0 for x° and 1 for y°.

y-(1)=3(x-(0)) Substitute (0,1)

y-1=3x Simplify

y=3x+1 Add 1 to both sides and you’re done

Step-by-step explanation:

In this problem, we can't find a specific value of x. In this case, we will find a range of value suitable for x.

[tex]\frac{x}{6} -6 < 8[/tex]

Add 6 to both sides

[tex]\frac{x}{6} <14[/tex]

Point A is located at negative 4 over 6 and point B is located at negative 1 over 6. What is the distance between points A and B?

negative 4 over 6 minus negative 1 over 6 = negative 3 over 6; therefore, the distance from A to B is absolute value of negative 3 over 6 equals negative 3 over 6 units
negative 4 over 6 minus negative 1 over 6 = negative 3 over 6; therefore, the distance from A to B is absolute value of negative 3 over 6 equals 3 over 6 units
negative 4 over 6 plus negative 1 over 6 = negative 5 over 6; therefore, the distance from A to B is absolute value of negative 5 over 6 equals 5 over 6 units

determine the effects on the graph of the parent function f(x)=x+10 when g(x)=0.3f(x)

Answers

Answer:

First, remember the definition of a vertical contraction/dilation.

If we have a function f(x), and we dilate it with a factor A, such as:

g(x) = A*f(x).

If A is larger than 1, then we are dilating the graph of f(x)

if A is smaller than 1, then we are contracting the graph of f(x).

In this case we have:

f(x) = x + 10 and g(x) = 0.3*f(x) = 0.3*x + 0.3*10 = 0.3*x + 3.

A = 0.3

then we have a contraction.

From this, we can conclude that the effects of this transformation in the graph will be that the graph of g(x) will be a vertical contraction of the graph of f(x).

(Where contracting means that in a given interval [x1, x2] the associated interval [f(x1), f(x2)] will be larger than [g(x1), g(x2)])

Below you can see both graphs, and see the difference between them, where green is f(x) and blue is g(x)

Item 1 Find the volume of the prism. A rectangular prism with length of start fraction 4 over 5 end fraction millimeter, width of one-half millimeter, and height of start fraction 3 over 8 end fraction millimeter. The volume is $$ cubic millimeter.

Answers

Answer:

The volume of the rectangular prism is 3/20 (or 0.15) mm³.

Step-by-step explanation:

The volume of the rectangular prism can be calculated as follows:

[tex] V = l*w*h [/tex]     (1)

Where:

l: is the length = 4/5 mm

w: is the width = 1/2 mm

h: is the height = 3/8 mm  

By entering the values of l, w, and h into equation (1) we can find the volume:

[tex] V = l*w*h = \frac{4}{5} mm*\frac{1}{2} mm*\frac{3}{8} mm = \frac{3}{20} mm^{3} = 0.15 mm^{3} [/tex]

Therefore, the volume of the rectangular prism is 3/20 (or 0.15) mm³.

To compute the date, you can use this algorithm, invented by the mathematician Carl Friedrich Gauss in 1800: 1. Let y be the year (such as 1800 or 2001). 2. Divide y by 19 and call the remainder a. Ignore the quotient. 3. Divide y by 100 to get a quotient b and a remainder c. 4. Divide b by 4 to get a quotient d and a remainder e. 5. Divide 8 * b 13 by 25 to get a quotient g. Ignore the remainder. 6. Divide 19 * a b - d - g 15 by 30 to get a remainder h. Ignore the quotient. 7. Divide c by 4 to get a quotient j and a remainder k. 8. Divide a 11 * h by 319 to get a quotient m. Ignore the remainder. 9. Divide 2 * e 2 * j - k - h m 32 by 7 to get a remainder r. Ignore the quotient. 10. Divide h - m r 90 by 25 to get a quotient n. Ignore the remainder. 11. Divide h - m r n 19 by 32 to get a remainder p. Ignore the quotient. Then Easter falls on day p of month n. For example, if y is 2001: a = 6 h = 18 n = 4b = 20, c = 1 j = 0, k = 1 p = 15d = 5, e = 0 m = 0 g = 6 r = 6Therefore, in 2001, Easter Sunday fell on April 15.
