How much would you pay for one roll of tape, two note pads, two highlighters, and two pens?

A. $4.50
B. $6.38
C. $8.07
D. $5.72

Answers

Answer 1
Hello!

Find the cost of each individual item.

1.28 / 2 = 0.64

Each roll of tape costs $0.64.

0.87 / 3 = 0.29

Each notebook costs $0.29.

Each highlighter costs $1.59.

1.98 / 2 = 0.99

Each pen costs $0.99.

One roll of tape is $0.64, two notepads are $0.58 two highlighters cost $3.18, two pens are 1.98.

Add them up: .

0.64 + 0.58 + 3.18 + 1.98 = 6.38

ANSWER:

You would pay B. $6.38.
Answer 2
We have to determine what it costs for one single item and then divide or multiply by the quantity needed.

1 roll Tape= $1.28÷2= $0.64

2 rolls Notepads= 0.87÷3= 0.29x2= $0.58

2 Highlighters= $1.59x2= $3.18

2 Pens= $1.98

Add these totals:
+0.64
+0.58
+3.18
+1.98
=$6.38

ANSWER: B) $6.38

Ashur solves the following system of linear equations.

Which statement about the solution to this system can he say is true?
The values of a and b are both equal to –4.
The values of a and b are both equal to 4.
The value of a is equal to 4, and b is equal to –4.
The value of a is equal to –4, and b is equal to 4.

Answers

a. first choice

The values of a and b are both equal to –4.

The given equations that make up the systems are:

-3a+7b=-16...................(Equation 1)

-9a+5b=16...................(Equation 2)

To find the values of a and b we will have to solve the two equations. To solve the equations let us employ the method of elimination.

Let us multiply (Equation 1) by -3. This will give us:

[tex] -3\times (-3a+7b=-16)=9a-21b=48 [/tex]...........(Equation 3)

Let us now add (Equation 2) to (Equation 3) to eliminate a. This will give us:

-16b=64

[tex] \therefore b=-4 [/tex]

Plugging this value of b in any of the equations we will get the value of a. Let us plug it in (Equation 1). This gives:

[tex] -3(-4)+7b=-16 [/tex]

[tex] 12+7b=-16 [/tex]

[tex] \therefore b=\frac{-28}{7}=-4 [/tex]

Thus, out of the given options, the first option is the correct one. The values of a and b are both equal to –4.

at 4:00 am,there were 800,000 gallons of water remaining at a reservoir.after 4 hours of irrigation,there were 100,000 gallons of water remaining.write an equation that describes the number of gallons of water as a function of the time the field has been irrigated

Answers

Let the[tex]x-axis[/tex] presents the time, and the [tex]y-axis [/tex] the gallons of water remaining, so our first point will be (4,800000). We know from the problem that after 4 hours, at 8:00 am, there were 100000 gallons, so our second point will be (8,100000).
To relate those two points we are going to use the point slope formula:
[tex]m= \frac{y_{2}-y_{1} }{x_{2}-x_{1} } [/tex]
where
[tex]x_{2}[/tex] is 8
[tex]x_{1}[/tex] is 4
[tex]y_{1}[/tex] is 800000
[tex]y_{2}[/tex] is 100000

So, [tex]m= \frac{100000-800000}{8-4} [/tex]
[tex]m= \frac{-700000}{4} [/tex]
[tex]m=-175000[/tex]

Now that we have our slope, we are going to use the point-slope formula to find our equation:
[tex]y-y_{1} =m(x-x_{1} )[/tex]
[tex]y-800000=-175000(x-4)[/tex]
[tex]y-800000=-175000x+700000[/tex]
[tex]y=-175000x+1500000[/tex]

The equation that describes the number of gallons of water as a function of the time the field has been irrigated is [tex]y=-175000x+1500000[/tex]
where
[tex]y[/tex] are the remaining gallons of water in the reservoir after [tex]x[/tex] hours 
[tex]x[/tex] is the time the field has been irrigated in hours

which is the directrix of parabola with equation x^2=4y

Answers

Answer:

[tex]y=-1[/tex]

Step-by-step explanation:

We have been given an equation of parabola [tex]x^2=4y[/tex]. We are asked to find the directrix of our given parabola.    

First of all, we will divide both sides of our given equation by 4.

[tex]\frac{x^2}{4}=\frac{4y}{4}[/tex]      

[tex]\frac{x^2}{4}=y[/tex]      

[tex]y=\frac{x^2}{4}[/tex]      

Now, we will compare our equation with vertex form of parabola:

[tex]y=a(x-h)^2+k[/tex], where, (h,k) represents vertex of parabola.

We can see that the value of a is [tex]\frac{1}{4}[/tex], [tex]h=0[/tex] and [tex]k=0[/tex].

Now, we will find distance of focus from vertex of parabola using formula [tex]p=\frac{1}{4a}[/tex].

Substituting the value of a in above formula, we will get:

[tex]p=\frac{1}{4*\frac{1}{4}}[/tex]

[tex]p=\frac{1}{1}=1[/tex]

We know that directrix of parabola is [tex]y=k-p[/tex].

Substituting the value of k and p in above formula, we will get:

[tex]y=0-1[/tex]

[tex]y=-1[/tex]

Therefore, the directrix of our given parabola is [tex]y=-1[/tex].

Factor completely. x^2−3x−40

Answers

This expression is a generic quadratic expression, so the first thing we need to look at is the last term (-40). Is it negative or positive? What are the factors of it? If the last term is negative, we know that one binomial is a subtraction while the other binomial is an addition. You may be asking, "an addition or subtraction of WHAT?" A binomial factored out of a quadratic expression would look something like this: (x + ____). The blank would equal a factor of the last term. In this case, a pair of factors that would fit is 8 and 5. 
8x5 = 40 and -8 + 5 = -3.

Plug it into the binomial example I provided above and....
(x - 8)(x+5)=40

Voila! You have your factored quadratic expression, hope this helps! 



To factor the quadratic expression x² -3x -40, we find that the expression factors into (x - 8)(x + 5).

The question involves factoring the quadratic expression x² -3x -40 completely. To factor this expression, we look for two numbers that multiply to -40 and add to -3. The numbers that meet these conditions are -8 and 5, since

(-8) * 5 = -40 and

(-8) + 5 = -3.

Therefore, the expression can be factored into (x - 8)(x + 5).

50 points! Dustin and Melanie are playing a game, where two standard, six-sided number cubes are rolled, and the sum of their outcomes is found. Each player gets a chance to guess the correct sum, and the player that guesses the correct sum wins the game.

Dustin decides to guess a sum of six. Melanie decides to guess a sum of seven.

Which player made the better decision? ________

Answers

Answer:

Melanie is the right answer

Step-by-step explanation:


Melanie made the better decision if Dustin and Melanie are playing a game, where two standard, six-sided number cubes are rolled.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

Dustin and Melanie are playing a game, where two standards, six-sided number cubes are rolled.

If the sum is 6:

The possible outcomes are = {(3,3), (2,4), (4,2), (1,5), and (5,1)}

Total outcomes = 5

If the sum is 7:

The possible outcomes are = {(1,6), (6,1), (5,2),( 2,5), (3, 4), (4,3)}

Total outcomes = 7

Thus, Melanie made the better decision if Dustin and Melanie are playing a game, where two standards, six-sided number cubes are rolled.

#SPJ2

A line includes the points (2, 10) and (1, 4). what is its equation in slope-intercept form?

Answers

Hi!

This problem has two parts. First you need to find the slope, so let's do that. The equation for the slope is m = y2-y1/x2-x1

We can now plug the two given points into the equation. 
m = 10-4/2-1
m = 6/1
m = 6

Now that we know the slope, and one point we can put this in slope intercept form. Slope intercept form is y=mx + b

So now we can plug in one point and the slope to find b

10 = 6(2) + b
10 = 12 + b
-2 = b

Now that we know both m and b, we can plug only those two into the equation y=mx + b, and we have the equation.

The equation is y = 6x - 2

side BC is opposite to angle A

Option 1 is correct. The side opposite to angle A is side BC, which is the hypotenuse.

In a triangle, the side opposite the right angle is known as the hypotenuse. Since angle A is given as a right angle in △ABC, the side opposite this right angle will be the hypotenuse.

In △ABC:

Side AB is adjacent to angle A, forming one leg of the right triangle.

Side AC is also adjacent to angle A, forming the other leg of the right triangle.

Side BC is opposite angle A and is the longest side of the triangle, making it the hypotenuse.

What is the solution of the equation 5x – 1 = 45? Round your answer to the nearest ten-thousandth

Answers

Final answer:

The solution to the equation 5x – 1 = 45 is x = 9.2, rounded to the nearest ten-thousandth.

Explanation:

The solution of the equation 5x – 1 = 45 is x = 9.2.

To solve this equation, we can start by isolating the variable x. Add 1 to both sides of the equation to get 5x = 46. Then, divide both sides by 5 to solve for x, giving us x = 9.2.

Therefore, the solution to the equation 5x – 1 = 45 is x = 9.2, rounded to the nearest ten-thousandth.
