Answer:

Step-by-step explanation:

Let's say the numbers are x and y, and y is larger than x.

x + y = 27

y = 6 + 2x

Substitute:

x + (6 + 2x) = 27

3x + 6 = 27

3x = 21

x = 7

So x = 7 and y = 20.

Step-by-step explanation:

Final answer:

To solve the equation x^2 - 9|||-3 = log3 x, simplify both sides of the equation and then find the values of x that satisfy the equation.

Explanation:

To find the values of x that satisfy the equation, we can start by simplifying both sides of the equation.

On the left side, we have x^2 - 9|||-3. To simplify this, we first evaluate the absolute value of -3, which is 3. Then we have x^2 - 9(3), which simplifies to x^2 - 27.

On the right side, we have log3 x.

Setting the two sides equal to each other, we have x^2 - 27 = log3 x.

To solve this equation, we can graph both sides and find the intersection points, or we can use numerical methods like iteration or Newton's method to find the approximate solutions.

Answer:

9

Step-by-step explanation:

coefficients = numbers in front of variables (x, x^2 etc)

so 5 + 3 + 1 = 9

In the expression 3x^4 + 5x^2 + x, the coefficients are 3, 5, and 1. Adding these values together gives a sum of 9.

In the expression 3x^4 + 5x^2 + x, the coefficients are 3, 5, and 1 respectively. The term x is implied to have a coefficient of 1 though it is not written explicitly. We find the sum of the coefficients by simply adding all these values together. So the sum would be 3 + 5 + 1 = 9.

Answer:

346 trucks are needed

Step-by-step explanation:

We know that one acre equals 43560 feet ^ 2

In this case the area is 3 acres. So:

[tex]3\ acres * \frac{43,560\ ft^2}{1\ acre} = 130,680\ ft^2[/tex]

We know that 1 foot equals 12 inches. So:

[tex]24\ in * \frac{1\ ft}{12\ in} = 2\ ft[/tex]

So the volume of the contaminated area is:

[tex]V = 2* 130,680\ ft^3\\\\V = 261,360\ ft^3[/tex]

In a cubic yard there are 27 cubic feet. So:

[tex]28\ yard^2 * \frac{27\ ft^3}{1\ yard^3} = 756\ ft^3[/tex]

Finally if we have a volume of [tex]261,360\ ft ^ 3[/tex] and each truck can transport [tex]756\ ft ^ 3[/tex] then the amount of trucks x we need is:

Answer:

Step-by-step explanation:

The factors of each term are ...

So, the greatest common factor is 3a. Factoring that out gives ...

  3a(16a^2 -25) . . . . . . matches answer 2

The factor in parentheses is the difference of squares, so it can be factored. You have memorized the form for the difference of squares ...

  p^2 -q^2 = (p -q)(p +q)

so you know the factoring of this with p=4a and q=5 will be ...

  3a(4a -5)(4a +5) . . . . . . matches answer 4

__

Any pair of factors can be multiplied by -1 without changing the value of the expression. So, two more answers are equivalent:

   (-3a)(-(16a^2 -25) = -3a(25 -16a^2) . . . . . . matches answer 5

  (-3a)(-(4a -5)(4a +5) = -3a(5 -4a)(5 +4a) . . . . . . matches answer 6

Answer:

2 4 5 6

Step-by-step explanation:

The highest common factor is 3a That means that 48a^3 must be divided by 3a which means 48a^3 / 3a = 16a^2. Notice what happened. 48/3 = 16. a^3/a = a^2.

Now you have to pull out 3a from 75a. That wasn't done to Answer 1. So answer one is incorrect.

75a/3a = 25

So far what you answer looks like is

3a(16a^2 - 25) which is answer 2

===========================================

Answer 3 is wrong because one of the factor has to be - 5. Neither one is.

===========================================

Answer 4 is correct

16a^2 - 25 factors into (4a - 5)(4a + 5)

So what is written reflects those factors + the 3a

==============================================

Now we come to the brutal ones.

If you take out a minus sign from the brackets, it has the effect of turning the two terms inside the brackets around.

-3a(25 - 16a^2) is what the above sentence means. so 5 is correct

==============================================

The two terms inside the brackets still factor

-3a ( 5 - 4a)(5 + 4a) It is just that they are turned around.

6 is correct.

We easily have

[tex]3x=0\iff x=0[/tex]

So, one solution is x=0.

The other solutions depend on the quadratic equation:

So, the solutions are [tex]x=-4,\ 0,\ 1[/tex]

Answer:

D

Step-by-step explanation:

The difference in the x-coordinates is Δx = 6 - 3 = 3.

The difference in the y-coordinates is Δy = 8 - 2 = 6.

One third the difference is Δx/3 = 3/3 = 1 and Δy/3 = 6/3 = 2.

So the one-third point is at (3 + 1, 2 + 2) = (4, 4).

In general the segment from A to B has parametric equation

X = (1-t)A + tB

t=0 gives point A, t=1 gives point B, and in between we move linearly with t from A to B.

So if we want AX:BX=1:3, that's 1/(1+3)=1/4 of the way along from A to B, so corresponds to t=1/4.  So the point we seek is

X = (1 - 1/4)(3, 2) + (1/4)(6,8) = ((9+6)/4, (6+8)/4)=(15/4, 7/2)

Answer:

[tex]x^{1/4} y^{1/2}[/tex]

Step-by-step explanation:

When you have a power then a root like that, you have to divide the power by the root.

So, in this case, you have (x^2y^4) and a 8th root (8√).

So, you take your exponents from (x^2y^4) and divide them by the root (8), to get new powers of 2/8, or 1/4, and 4/8 or 1/2

As I already explained you in other questions, that leaves a fractional exponent that is equivalent to the regular exponent then rooted.

Final answer:

The sum of the first and twelfth terms of an arithmetic progression, whose first 12 terms sum to 156, is 26. This is determined by using the arithmetic progression sum formula and understanding that the sum of equidistant terms from the beginning and end of the series is constant.

Explanation:

To determine the sum of the first and twelfth terms of an arithmetic progression (AP) given the sum of the first 12 terms, we can use the properties of AP. The sum of an arithmetic progression can be expressed using the formula Sn = n/2(2a + (n-1)d), where Sn is the sum of the first n terms, a is the first term, n is the number of terms, and d is the common difference.

For this question, the sum of the first 12 terms (S12) is given as 156, and we want to find the sum of the first and twelfth terms. By properties of AP, the sum of equidistant terms from the beginning and end (first and last terms in this case) is the same. So the sum of the first and twelfth terms is equal to the sum of the second and eleventh terms, and so on. This sum is consistent and equals a + a + 11d, which simplifies to 2a + 11d.

Since S12 = 12/2(2a + 11d) and we know S12 = 156, we can simplify the formula to get 156 = 6(2a + 11d). However, to solve for 2a + 11d directly, we do not need the value of d; we only need the fact that the sum of the first and last terms will be constant and equal to the sum of 2a + 11d. Therefore, the sum of the first and twelfth terms is 156/6, which equals 26.

To calculate probability with and without replacements, we adjust the number of total outcomes depending on whether the card is replaced or not after each draw. For this specific scenario, when there is no replacement, the probability of drawing a red bird and then a lion is (5/20)*(5/19), while with replacement it is (5/20)*(5/20).

Your question involves the concepts of probability and specifically the difference between sampling with and without replacement. Let's assume, for the sake of this example, that there are 5 red bird cards and 5 lion cards in the deck of 20 cards.

1. Sampling without replacement: After the first card (a red bird) is taken out, it is not added back into the deck. So the deck now only has 19 cards. So, the probability of drawing a red bird card first is 5/20 or 1/4. Then, the probability of drawing a lion card second is 5/19.

2. Sampling with replacement: After the first card (a red bird) is pulled out, it is replaced back into the deck. So the deck continues to have 20 cards. So, the probability of drawing a red bird first is still 5/20 or 1/4 and the probability of drawing a lion card second is still 5/20 or 1/4.

a. On Graph B, at 0 minutes, the height of the graph will be 12 miles.

b. Then, the graph will decrease linearly until 15 minutes, when Adalyn reaches the school.

Certainly, let's delve a bit deeper into each part of Graph B in relation to Adalyn's journey from home to school and back:

a. Initial Point at 0 Minutes:

On Graph B, the vertical axis represents the distance from the school, while the horizontal axis represents time. At the start of her journey (0 minutes), Adalyn is at her home, which is 12 miles from the school. This is the farthest point from the school she will be during her trip. Therefore, the height of Graph B at 0 minutes must be the full distance to the school, which is 12 miles. This is the starting point for the graph on the vertical axis.

b. Graph Behavior from 0 to 15 Minutes:

As time progresses from 0 to 15 minutes, Adalyn is driving towards the school, getting closer every minute. On the graph, this is represented by a decreasing line, since the vertical distance from any point on the line to the horizontal axis represents her distance from the school, which is getting smaller. The rate of decrease is constant because we're assuming she's driving at a steady pace.

At exactly 15 minutes, Adalyn reaches the school. Since she is now at the school, her distance from it is 0 miles. On Graph B, this is represented by the graph touching the horizontal axis. At this point, the height of the graph is 0 miles, indicating that there is no distance between Adalyn and the school.

After 15 minutes, the graph would stay at 0 miles (the line would run along the horizontal axis) until she begins her journey back home. Once she starts the return trip, the graph would begin to increase linearly from 0, reflecting her increasing distance from the school as she drives back home.

If we were to continue completing Graph B based on Graph A, after the 15-minute mark, we'd see a flat line at 0 miles until 60 minutes when Adalyn starts her journey back home, at which point the line would ascend back to 12 miles by 75 minutes, mirroring the initial descent but in the opposite direction.

The word which completes the statement are,

12 miles,

Steady,

Decrease

Complete each statement about Graph B.

On graph B, at 0 minutes, the height of the graph will be 12 miles.

Then, the graph will remain steady until 15 minutes, the height of graph B will be decreased.

Therefore, graph B is the reverse of graph A which is the distance from the school to her home.

To determine if pentagon DEFGH has 5 congruent angles, Peter needs to consider if it is a regular pentagon. Regular pentagons have 5 congruent sides and angles. In such pentagons, each angle measures 108°.

Peter can determine if the pentagon has 5 congruent angles by checking if it is a regular pentagon. A regular pentagon is defined as having all its sides and angles equal. If the pentagon DEFGH is regular, it will have 5 congruent sides and 5 congruent angles.

The Pythagorean theorem would apply if DEFGH were a triangle, where D and L are sides with hypotenuse s. For pentagons, the theorem is not applicable. It's important to remember that the angles of any pentagon add up to 540°. So, in a regular pentagon, each angle measures 108° because 540°/5=108°.
