The possible outcome could be 4 or 3

Step-by-step explanation:

Answer:

2/3

Step-by-step explanation:

There are 12 possible outcomes. Of the 12, 6 are even and 4 have B's. That would give up 10/12. But then you would subtract the possible outcomes that are BOTH even AND have a B. Only 2 possible outcomes have an even number and the letter B. So 10 minus 2 is 8. That would give you 8/12. Simplify and you will get your answer of 2/3!

Just took the test, so trust me on this fellow K12ers!

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:

6d5-3c3d2+5c2d3-12CD4+8

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

Answer:

x = 57.22754579  

Step-by-step explanation:

We know cos 63 = adjacent/ hypotenuse

                  cos 63 =  15 sqrt(3)/x

Multiply each side by x

x cos 63 =15 sqrt( 3 )

Divide each side by cos 63

x cos (63)/ cos (63) = 15 sqrt(3)/cos (63)

  x = 15 sqrt(3)/ cos 63

x = 57.22754579  

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.

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.

Answer:

This equation has no solution

Step-by-step explanation:

To find our many solution the system of equation has, we need to  solve simultaneously, we can either solve by substitution method, by elimination method or both method.

We will be using substitution method to solve.

Here are the system of equation;

y= -4x+2 ----------(1)

24x+6y=6---------(2)

First, we are going to substitute equation (1) in equation (3)

{what we mean by substituting equation (1) in equation (2) is then any where we see y in equation (2),  we will be replacing it by[-4x + 2]}

24x + 6(-4x + 2)  = 6

Then, we will go ahead and open the bracket

24x  -  24x  +  12  =6

This simply shows that there is no solution to this system of equation

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:

The cost of one box of oranges = $3.3

Step-by-step explanation:

Let x be cost of one box of oranges and y be the cost of one box of grapefruit.

We have been given that Mrs. Whitten purchased 3 boxes of oranges and 2 boxes of grapefruit from a student for a total of $22.50. We can represent this information as:

[tex]3x+2y=22.50...(1)[/tex]  

Mr. Rutig purchased 1 box of oranges and four boxes of grapefruit, spending a total of $28.50. We can represent this information as:

[tex]x+4y=28.50...(2)[/tex]

We will solve our system of linear equations using substitution method.

From equation (1) we will get,

[tex]y=\frac{22.50-3x}{2}[/tex]

Substituting y's value in equation (2) we will get,

[tex]x+4*(\frac{22.50-3x}{2})=28.50[/tex]

[tex]x+2*(22.50-3x)=28.50[/tex]

Upon distributing 2 we will get,

[tex]x+45-6x=28.50[/tex]

[tex]x-6x=28.50-45[/tex]

[tex]-5x=-16.5[/tex]

[tex]x=\frac{-16.5}{-5}[/tex]

[tex]x=3.3[/tex]

Therefore, the cost of one box of oranges is $3.3.

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:

A protractor.

Step-by-step explanation:

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.

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.

Step-by-step explanation:

The explicit formula used for calculating the account's balance is given by:

A= P(1+R)^T

where: A= Amount (account's balance)

P= Principal  (700)

R= Rate (5%)

T= Time   (3 years) [since, the balance is calculated in the beginning of the  forth year]

A= P(1+R)^T

A = 700(1+0.05)^3

  = 700(1.05)^3

  = 700*1.157

  = 810.34

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.

Answer:

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.
