Step-by-step explanation:  V= Voltage

                                               I= Current

                                               R= Resistance

Ohm's Law Mathematically expressed as: I= V/R or V= IR or R= V/I

V= 500

I= ?

R= 250

I= V/R

I= 500/250

Answer:

(11,-2)

Step-by-step explanation:

11+5 /2=  8

6+-2= -4/2=-2

Answer:

(11,-2)

Step-by-step explanation:

The one point you have is P(5,6)

The midpoint is (8,2)

The other point is (x,y)

(x + 5) /2 = 8

(x + 5) = 8*2

x + 5 = 16

x = 16-5

x = 11

===========

(y + 6)/2 = 2

y + 6 = 2*2

y + 6 = 4

y = 4 - 6

y = - 2

Answer:

2/3

Step-by-step explanation:

rise over run so you go done then over

Answer:

2/3

Step-by-step explanation:

When counting the slope from points, I like to use this method. Pick 2 points you see the line crosses through and then count the steps up/down and to the side one is from the other. In this case, you can count like this:

"Up 2, over 3"

Now we know the slope is 2/3.

$319.68

Step-by-step explanation:

First, you have to add up all the hours. 4 + 4.5 + 7.25 + 12 = 27.25. Then, you multiply that times the amount of money per hour (11.52) and get $319.68 for the whole week. Hope this helped! If it did, please mark me as brainliest. Thanks!

Answer:

Step-by-step explanation:

At home depot

Price of Christmas tree = $149.00

Discount = 15%

Amount discounted = 15% of $149

Amount discounted = 15/100 * $149

Amount discounted = 15 * 1.49

Amount discounted = $22.35

Amount she paid = $149-$22.35

Amount she paid = $126.65

At Lowe's:

Price of Christmas tree = $175.00

Discount = 260%

Amount discounted = 20% of $175

Amount discounted = 20/100 * $175

Amount discounted = 0.2 * 175

Amount discounted = $35

Amount she paid = $175-$35

Amount she paid at Lowe's = $140

From the prices above, it can be seen that Home Depot has a better deal since the price after removing discount is lower than that of Lowe's.

Amount she will save will be $140 - $126.65 = $13.35

Answer:

Step-by-step explanation:

Step one:

given that the box is 30 ounce of cereal.

for Jiro----who ate 3/10 of the 30 ounce

=3/10*30

=9 ounce

Jiro ate 9 ounce

step two:

for Joey----who ate 5/10 of the 30 ounce

=5/10*30

=15 ounce

Joey ate 15ounce

the total ounces that both of them ate is

=9+15

=24

therefore the ounce left

=30-24

=6 ounce of cereal

The left over is 6 ounce of cereal

Step-by-step explanation:

Answer:

Step-by-step explanation:

Step one:

given data

needed amount= $80

the amount already saved= $8

earnings per hour= $9

let the number of hours worked be n

and let y represent the total

the situation represented linearly is

y=mn+c

Step two:

substituting our data to find n

9n+8>80

9n>80-8

9n>72

divide both sides by 9

n>72/9

n>8

Therefore he must work a minimum of  8houees

Step-by-step explanation:

Answer:

The correct answer for me was true

Step-by-step explanation:

Answer: x=3

Step-by-step explanation:

1. First lets do the parenthesis 3(4x+2) to get 12x+6

2. 12x+6=8x+24-2x (combine like terms) first lets do 8x and 2x first so its 8-2= 6x

3. 12x+6=6x+24 (now subtract 12x by 6x to get 6x)

4. 6x+6= 24 (now subtract 24 by 6 to get 18)

5. 6x= 18 (now divide 18 by 6 to get 3)

Answer:

Step-by-step explanation:

[tex]3(4x+2)=8x+24−2x[/tex]

Expand and simplify

We have

[tex]12x + 6 = 8x + 24 - 2x \\ 12x + 6 = 6x + 24[/tex]

Move 6x to the left side of the equation

[tex]12x - 6x + 6 = 24 \\ 6x + 6 = 24[/tex]

Move 6 to the right side of the equation

[tex]6x = 24 - 6 \\ 6x = 18[/tex]

Divide both sides by 6

[tex] \frac{6x}{6} = \frac{18}{6} \\ [/tex]

We have the final answer as

Answer:

Pat Pet's Palace

Step-by-step explanation:

Price of dog food at Pat Pet's Palace = $3 per pound

Price of dog food at Mark's Mutt Market can be estimated using the graph given.

The graph is a proportional graph, thus, the constant of proportionality between cost and pound = y/x

Using the coordinates of a point on the line, (2.5, 10), constant of proportionality or unit rate = y/x = 10/2.5 = 4.

This means the price of dog food at Mark's Mutt Market is $4 per pound.

Therefore, Milo would pay a lower price per pound for dog food at Pat Pet's Palace.

Answer:

  The domain is always discrete when it is found from a table.

Step-by-step explanation:

A table necessarily lists a finite number of discrete points. The domain, as found from a table, is always discrete.

__

If the table is said to be a representation of a continuous function, then the domain of that continuous function will be continuous.

Your question seems to have to do with a table alone, not a table and an equation, or a table and a graph. A table (of points) alone cannot express a continuous domain.

__

Additional comments

One can conceive of tables that would have continuous domains, as, for example, a table with entries ...

  (x, y) = (0 ≤ x < 3, 3x+2), (3 ≤ x < 6, 4x-1), ...

Such a table is not a list of points, but is a piecewise function definition. We presume this is not what you're concerned with.

Answer:

The probability that the next customer will pay with credit card is approximately 0.33

Step-by-step explanation:

The given parameters are;

The number of customers that paid cash = 80 customers

The number of customers that used a debit card = 7 customers

The number of customers that used a credit card = 42 customers

The total number of different payments made = 80 + 7 + 42 = 129 payment

Probability = The number of desired outcome/(The number of possible outcome)

The probability that the next customer will pay with credit card = (The number of customers that used a credit card)/(The total number of different payments made)

∴ The probability that the next customer will pay with credit card = 42/129 ≈ 0.33 to the nearest hundredth.

Answer:

6/36

Step-by-step explanation:

1/36 + 5/36 = 6/36 OR 1/6

Answer:

1/5 of the farmers land has potatoes and pea plants growing on it

Step-by-step explanation:

so we are trying to figure out how much of the land is covered in potatoes and pea plants together so we add their fractions together

1/36 + 5/36 = 6/36

we then simplify the fraction by dividing both numbers by 6 since 6 can go equally within the fraction:

6/36 divided by 6  = 1/5

so 1/5 of his land is covered by potatoes and pea plants

Step-by-step explanation:

The slope of the perpendicular line will be - 5/8.

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (2, 1) and (7, 9).

Now,

Since, We know that;

The slope of the line passing through the points (x₁ , y₁) and (x₂, y₂) is;

⇒ m = (y₂ - y₁) / (x₂ - x₁)

So, The slope of the line passing through the points (2, 1) and (7, 9) is;

⇒ m = (y₂ - y₁) / (x₂ - x₁)

⇒ m = (9 - 1) / (7 - 2)

⇒ m = 8 / 5

Since, The product of the slope of the perpendicular lines is - 1.

Here,  Line b is perpendicular to a.

So, The slope of the line b is,

m₂ = - (1/8/5)

    = - 5/8

Thus, The slope of the perpendicular line will be - 5/8.

The value of c that completes the square  [tex]x^2+2x+c[/tex] is 1

Step-by-step explanation:

We need to find the value of c that completes the square  [tex]x^2+2x+c[/tex]

The formula used will be: [tex]a^2+2ab+b^2=(a+b)^2[/tex]

In the question given the value c can be found by breaking the middle term. we are given 2x while the general formula is 2ab for middle term so,

2(x)(1) = 2x

so, c= 1

Solving:

[tex]x^2+2x+c\\=x^2+2(x)(1)+(1)^2-(1)^2\\=(x+1)^2-1[/tex]

So, the value of c that completes the square  [tex]x^2+2x+c[/tex] is 1

Answer: She can make 20 liters of chai.

Step-by-step explanation:

As per given,

1 liter of chair requires 0.15 g of secret ingredient.

So , for 1 g of secret ingredient , quantity of chai she would make = [tex]\dfrac{1}{0.15}=\dfrac{100}{15}[/tex]

For 3g  of secret ingredient , quantity of chai she would make = [tex]\dfrac{100}{15}\times3[/tex]

[tex]=\dfrac{100}{5}=20[/tex]

Hence, she can make 20 liters of chai.

She will need 20 litres of chili for 3g of the ingredient

If Sarah is making chili she has 0.15 g of a secret ingredient to each liter of chili, this is expressed as:

0.15g = 1 chili

To get the amount of chili needed for 3g, we can write;

3g = x

Divide both expression

0.15/3 = 1/x

x = 3/0.15

x = 20

Hence she will need 20 litres of chili for 3g of the ingredient
