Answer:

$2.44

Step-by-step explanation:

Change the percentage into a decimal. Move the decimal point to the left two place values.

25% = 25/100 = 0.25

Multiply the two numbers:

3.25 x 0.25 = 0.8125

Subtract the number gotten from the original number. Remember to first simplify.

0.8125 = 0.81

3.25 - 0.81 = 2.44

$2.44 is your new price.

In the given case, Rashida can make approximately 9 cupcakes with 1 cup of flour.

To determine how many cupcakes Rashida can make with the 1 cup of flour she has, we need to calculate the conversion factor between the given measurement of 1 2/3 cups of flour and the available 1 cup of flour.

The conversion factor is found by dividing the available amount by the required amount

(1 cup ÷ 1 2/3 cups).

We can simplify the fraction to obtain a decimal,

1 ÷ (5/3) = 3/5 ≈ 0.6.

So, Rashida can make approximately

0.6 × 1 1/4 dozen = 0.6 × 15 = 9 cupcakes.

Answer:

x = 26.4      y= 17

Step-by-step explanation:

Set up proportions.

To find x:

Set 12 over x is equal to 10 over 22.

12 times 22 = 264

264 / 10  =x

x =  26.4

To find y:

Set y over 37.4 is equal to 10 over 22.

37.4 times 10 =  374

374 / 22

y = 17

Answer:

The answer is 2 times x.

Step-by-step explanation:

X is the number of students. If each of the student received 2 pencils then you multiply 2 by the number of students.

Answer:

The answer is 2 times x.

Step-by-step explanation:

X represents the number of students. If each of her student received 2 pencils, you would multiply 2 by the number of students.

It would be 7.

Here's why:

7 + - 6 = 1

1 = 1

It's a TRUE statement!

Hope this helps you!!!! :)

The integer value that makes the sentence true is 7, as in mathematics, adding a negative number 6 to a number, to yield 1, equates deducting 6 from that number to yield 1.

This is a mathematics problem involving the concept of integer addition. In mathematics, adding a negative number is equivalent to subtracting that number's absolute value. Therefore, to find the integer that makes the addition sentence true, you would need to identify the number that, when subtracted by 6, equals 1.

So, the equation can be rewritten as X - 6 = 1. If you add 6 on both sides of the equation to isolate the variable X on one side, the equation becomes X = 1 + 6. As a result, it is clear that the integer value X that would make the equation + -6 = 1 true is 7.

Answer:

A) -7.888

Step-by-step explanation:

The answer is A because it is an never ending number, which means it is irrational

The following numbers is irrational D) √0.025, which is an irrational number.

To determine which of the given numbers is irrational, we need to understand what an irrational number is. An irrational number is a real number that cannot be expressed as a fraction (i.e., it cannot be written as a ratio of two integers). Irrational numbers have non-repeating, non-terminating decimal expansions.

Let's evaluate each of the given options:

A) -7.8: This is a rational number because it can be expressed as -78/10 or -39/5, which is a ratio of two integers.

B) √25: This is a rational number because it is equal to 5, which can be expressed as 5/1. It's a ratio of two integers.

C) 25.8125: This is a rational number because it can be expressed as 258125/10000, which is a ratio of two integers.

D) √0.025: This is an irrational number. To see why, we can simplify it. √0.025 is the same as √(25/1000), which simplifies to √(1/40). The square root of 1 is 1, and the square root of 40 is a non-repeating, non-terminating decimal, making √0.025 an irrational number.

After withdrawing $40 from a checking account with a balance of -$30, Selene's checking account balance becomes -$70.

Selene's checking account balance is initially at -$30. When she withdraws an additional $40, the balance goes further negative.

To find Selene's checking account balance after the withdrawal, we need to subtract the withdrawal amount from the initial balance. Her initial balance is -$30, and she withdrew $40 more.

To find the new balance, you subtract $40 from -$30.

Account Balance Calculation:

Therefore, Selene's checking account balance after the withdrawal is -$70.

Final answer:

After withdrawing an additional $40 from an initial balance of -$30, Selene's checking account balance is -$70.

Explanation:

Selene's checking account balance after the withdrawal can be determined by subtracting the amount withdrawn from her initial balance. She starts with a balance of -$30. After withdrawing an additional $40, the new balance can be calculated as follows:

Initial balance: -$30
Withdrawal: -$40
New balance: -$30 - $40 = -$70

Thus, Selene's checking account balance after the withdrawal is -$70.

We can see here that the function can be written as:

f(x) = 66 + (12 × x)

To determine how many water bottles Lakita will buy, we need to consider the number of water bottles she already has (66) and the number of boxes she can afford to buy (up to 5). Each box contains 12 water bottles.

We can create a function to represent this situation:

Let's define:

x = the number of boxes Lakita will buy

The total number of water bottles Lakita will have is:

Total number of water bottles = 66 + (12 × x)

The reasonable domain for this function is 0 ≤ x ≤ 5, as Lakita can buy up to 5 boxes of water bottles.

The range of the function represents the total number of water bottles Lakita will have, which depends on the value of x. The range can be expressed as:

Range: 66 ≤ Total number of water bottles ≤ 126

So, the function can be written as:

f(x) = 66 + (12 × x)

Where:

x = the number of boxes Lakita will buy, and

f(x) = the total number of water bottles she will have.

Final answer:

The value of t on the interval [-2π,2π] for which sin(t)=1 is only at t=π/2, since this is where the sine function reaches its maximum value within the given range.

Explanation:

The question asks: For what values of t on the interval [-2π,2π] is sin(t)=1? To answer this, we must understand when the sine function reaches its maximum value of 1. In the unit circle, θ represents the angle in radians from the positive x-axis. The sine function reaches its maximum value of 1 at an angle of θ=π/2 radians. Therefore, within the interval [-2π,2π], sin(t)=1 only at t=π/2. However, the function is periodic with a period of 2π, meaning it repeats every 2π intervals. Even though the question's range allows for multiple cycles of sine's period, only π/2 falls within those bounds with the value of sin(t) exactly equal to 1.

Answer:

5 minutes to run 1 kilometer

Step-by-step explanation:

Alonzo takes 12 minutes to run 6 times around a 400-meter track.

6 times around a 400 m track

400 * 6 = 2400 meters

It take 12 minutes to run 2400 meters

2400 meters = 2400/1000 = 2.4km

distance = 2.4 km  and time = 12 minutes

Now we find our constant speed

[tex]Distance = speed * time[/tex]

2.4 = speed * 12

divide by 12 on both sides

speed = 0.2

so speed is 0.2 km per minute

Now we find out time when distance = 1km

Distance = speed * time

1 = 0.2 * t

divide by 0.2 on both sides

5 = t

So it take 5 minutes to run 1 kilometer

The other added polynomial is 6d^5-3c^3d^2+5c^2d^3-12CD^4+8.

To find the other polynomial, we need to subtract the given polynomial from the sum of the two polynomials. The sum of the two polynomials is 8d5-3c3d2+5c2d3-4CD4+9. The polynomial that is added is 2d5-c3d4+8CD4+1.

Subtracting the given polynomial from the sum, we get:

8d5-3c3d2+5c2d3-4CD4+9 - (2d5-c3d4+8CD4+1)

Simplifying the polynomial, we get:

Answer:

The value of k is 4.

Step-by-step explanation:

To find the missing coordinate, we can use the slope equation and plug in all known values.

m(slope) = (y2 - y1)/(x2 - x1)

-1 = (k - 0)/(-2 - 2)

-1 = k/-4

Now we can solve using cross multiplication.

-1 = k/-4

k*1 = -1*-4

k = 4

Answer:

y = 32

Step-by-step explanation:

4 + y = 36

to work out y you need to make it by itself

so take the 4 to the other side

36 - 4 = y

so y equals 32

Answer:

x = 4

Step-by-step explanation:

3x = 48

Divide both sides by 3

x = 16

Then do 16/4 since 4 of the sides equal the same amount

x = 4

Answer:

y = - 5x - 1

Step-by-step explanation:

The first thing to do (always) is pay attention to x =0. That at least gives you a partial answer. y = y' - 1. when you put 0 in for whatever y' is you get 0. What about the other numbers? How did they come about.

We have another clue. Whenever you put in a positive number for x, you get a negative answer for y. That's interesting. So y' has a minus sign associated with it.

y = -ax - 1    Make a>0 so there is only 1 minus sign. x cannot have an even power, because an even power would make everything positive except the -1.  

So we'll start with y= - ax - 1 We'll also make the assumption that a = 1

y = - x - 1 That won't work. a >1 otherwise x = 2 won't give - 11

y = -ax - 1

let x = 2

let y = - 11 Solve for a

y = - ax - 1

- 11 = -a*-2 - 1       add   1  to both sides

-11 + 1 = - a(-2) - 1 + 1

- 10 = -2a             Divide by - 2

- 10/-2 = -2a/-2

a = 5

Answer: y = - 5x - 1

Use the Pythagorean theorem:

[tex]x^2+4^2=10^2[/tex]

[tex]x^2+16=100[/tex]        subtract 16 from both sides

[tex]x^2=84\to x=\sqrt{84}\\\\x=\sqrt{4\cdot21}\\\\x=\sqrt4\cdot\sqrt{21}\\\\\boxed{2\sqrt{21}}[/tex]

Answer:

A: There is no solution

Step-by-step explanation:

This is not a very likable question.

Y=3x-4

9x-3y=14

Put the y value from the first equation into the second.

9x - 3(3x - 4) = 14               Remove the brackets

9x - 9x + 12 = 14               Combine like terms on the left

12 = 14                                 When you get this kind of conclusion, that means there is no solution. I'll graph these two for you.

Blue: y =3x - 4

Green: 9x - 3y = 14

They never touch they never meet: they are parallel. They don't give a solution.

Answer:

- 1/5

Step-by-step explanation:

the answer is the one highlighted #1

but to do this you must first change the decimal to a fraction. Personally i use a decimal calculator.

then you go to where the 3 is on the Y axes. since its positive 3 it would be 3 up instead of down.

then you count over how ever many the X is. this is 1/2 so you go over 1 time then up 2 times.

Personally I like the triangle method where u plot the +3 then draw on the line 1 over then 3 up

if u need to find out what the plot line u can keep doing that all the way up and just reverse it when u go down.

Answer:

Both set A and B.

Step-by-step explanation:

Set A: (-1, 0), (-2, 1), (4, 3), (3, 4)

Set B: (1, 4), (2, 3), (3, 2), (4, 1)

Set C: (2, 1), (3, 2), (2, 3), (1, 4)

In order for (x,y) to be a function, only one x get the value of y, but many x'es can get the value y.

Looking at the set A and B, and the definition above, we can say that they are functions.

What about set C? It is not a function, as x = 2 is equal 1 or 3, which does not meet the condition from the definition.

Final answer:

Both Set A and Set B are functions because each member of the domain in these sets maps to a unique value in the range. Set C is not a function because the same first element maps to different values in the range. Both set A and B are the answers.

Explanation:

To determine which set(s) represent a function, we need to ensure that each element of the domain maps to one and only one value in the range. By examining each set:

Set A: (-1, 0), (-2, 1), (4, 3), (3, 4): Every first element is unique, indicating a function.

Set B: (1, 4), (2, 3), (3, 2), (4, 1): Similarly, all first elements are unique, indicating a function.

Set C: (2, 1), (3, 2), (2, 3), (1, 4): The number 2 appears twice as a first element with different second elements, violating the definition of a function.

Therefore, both sets A and B represent functions since they each map every member of the domain to a unique member of the range, while set C does not.

The answer is b. Both Set A and Set B are functions.
