Your answer is therefore D.

I hope this helps! :)

Answer:

D) 4502

Step-by-step explanation:

It is given that,

Points for first place = 4 points

Second place = 2 points

Third place = 1 point

Thus, First Place Vote : 4 × 867 = 3468

Second Place Vote: 2 × 301= 602

Harold moves no more than 43 of his sheep and goats into another field. Fewer than 22 of his animals are goats.

Let s represent the number of sheep and g represent the number of goats identify two inequalities that represent this situation.

A. g<22
B. s>22
C. s+<43 with the line under
D. s-g<45 with the line under

Answers

Answer:Options 'A' and 'C' are correct.

Step-by-step explanation:

Let the number of sheep be 's'.

Let the number of goats be 'g'.

According to question, we have given that

the number of sheep and goats are not more than 43.

The number of goats are fewer than 22.

So, the inequalities would be

[tex]g<22\\\\and\\\\s+g<43[/tex]

Hence, Options 'A' and 'C' are correct.

The two inequalities for Harold's sheep and goats situation are A. g < 22 and C. s + g ≤ 43.

To represent the situation described about Harold's sheep and goats, we need to set up two inequalities based on the given information:

A. g < 22: This inequality indicates that the number of goats (g) is fewer than 22.C. s + g ≤ 43: This inequality means that the total number of sheep and goats combined (s + g) is at most 43.

Using these inequalities, we can help Harold determine how to distribute his sheep and goats in the new field.

HELPPPPPPP Consider the equation 3/4 y = 2.4x. Solve the equation for y. What is the constant of proportionality?

Answers

1.8y is the answer because first you do 3/4y into a decimals number and then it’s 0.75 then I times it by 2.4 which is 1.8y

Final answer:

To solve the equation 3/4 y = 2.4x for y, we multiply both sides of the equation by 4/3 to eliminate the fraction. Simplifying the equation gives us y = 3.2x. The constant of proportionality in this equation is 3.2.

Explanation:

To solve the equation 3/4 y = 2.4x for y, we need to isolate y on one side of the equation. First, we can multiply both sides of the equation by 4/3 to eliminate the fraction:

3/4 * y = 2.4x

y = (2.4x)/(3/4)

Next, we can simplify the equation by multiplying the numerator and denominator of the fraction by the reciprocal of 3/4, which is 4/3:

y = (2.4x) * (4/3)

y = (9.6x)/3

y = 3.2x

Therefore, the equation 3/4 y = 2.4x can be solved for y to give the expression y = 3.2x. The constant of proportionality in this equation is 3.2, which indicates that y is directly proportional to x with a scale factor of 3.2.

Answers

Answer:

The height of the prism is [tex]1\frac{1}{6}[/tex] units ⇒ answer a

The number of blocks needed is 133 ⇒ answer c

Step-by-step explanation:

* Lets explain how to solve the problem

- The volume of a rectangular prism is

→ V = Area of the base × its height

- The volume of the rectangular prism is [tex]3\frac{25}{36}[/tex] units³

- The area of its base is [tex]3\frac{1}{6}[/tex] units²

- Substitute the values of the volume and area of the base in the rule

∴ [tex]3\frac{25}{36}=3\frac{1}{6}*h[/tex]

- Divide the two sides by [tex]3\frac{1}{6}[/tex]

∴ [tex]h=\frac{7}{6}=1\frac{1}{6}[/tex] units

* The height of the prism is [tex]1\frac{1}{6}[/tex] units

- The volume of each cubic block is [tex]\frac{1}{36}[/tex] units³

- The number of blocks = volume of the prism ÷ volume of the block

∵ The volume of the prism is [tex]3\frac{25}{36}[/tex] units³

∵ The volume of each block is [tex]\frac{1}{36}[/tex] units³

∴ The number of blocks = [tex]3\frac{25}{36}[/tex] ÷ [tex]\frac{1}{36}=133[/tex]

∴ The number of blocks = 133

* The number of blocks needed is 133

Write the equation of the circle in general form. Show all of your work.

Answers

Answer:

x^2 + y^2 + 6x - 8y + 21= 0.

Step-by-step explanation:

The center of this circle is (-3, 4) and the radius id 2.

So in Standard form, the equation is:

(x + 3)^2 + ( y - 4)^2 = 2^2

Converting to General form we have:

x^2 + 6x + 9  + y^2 - 8y + 16 = 4

x^2 + y^2 + 6x - 8y + 9 + 16 - 4 = 0

x^2 + y^2 + 6x - 8y + 21= 0.

In a game a die numbered 9 through 14 is rolled. What is the probability that the value of a roll will be a multiple of two or ten?

Answers

Answer:

Step-by-step explanation:

This is a special die.  Its six sides bear the numbers {9, 10, 11, 12, 13, 14}.

There are three possibilities for getting a multiple of two:  {10, 12, 14}, and

there is only one possibilities for getting a multiple of ten:  {10, 12, 14}

The probability here of getting a multiple of two is 3/6, and that of getting a multiple of ten is 1/6.  But one of the outcomes is found in both result sets:  10.  Getting a multiple of 10 is already included in the event that the outcome is a multiple of two.  My answer here would be 3/6, or 1/2.

the probability of rolling a multiple of two or ten is 4/6, which simplifies to 2/3.

The probability of rolling a multiple of two or ten on a die numbered 9 through 14 can be calculated as follows:

Numbers that are multiples of two in the given range are 10, 12, and 14, which are 3 possibilities.Numbers that are multiples of ten in the given range are 10, which is 1 possibility.Therefore, the total favorable outcomes are 3 (for multiples of two) + 1 (for a multiple of ten) = 4. The total possible outcomes from 9 through 14 are 6.Hence, the probability of rolling a multiple of two or ten is 4/6, which simplifies to 2/3.

The equation h = ?16t2 + 40t + 30 models the projectile's h height at t seconds. How long will it take for the projectile to hit its target on the ground? (to the nearest tenth of a second)

Answers

Answer:

t = 3.1 seconds

Step-by-step explanation:

Set the equation h = -16t^2 + 40t + 30 equal to 0 (0 represents ground level).

Then h = -16t^2 + 40t + 30 = 0

Applying the quadratic formula with a = -16, b = 40 and c = 30,

      -40 ± √( 1600 - 4[-16][30] )

t = -----------------------------------------

                  2(-16)

      -40 ± √ 3520

t = -------------------------

             -32

                                                                               -40 - 59.33

Only the positive t value makes sense.  It is t = ------------------

The sum of two numbers is equal to 63 and their difference is equal to 12. Find the numbers.

Answers

Answer:

a + b = 63

a - b = 12

So, a - b = 12 which can also be written as a = b + 12

Then use substitution and plug in (b + 12) for a in the first equation

(b+12) + b =63

-12              -12

---------------------

2b  =  51 so b=25.5

Now, you know b which can be used to find a

Which of the following is equal to sqrt. (50(a^6) (b^7))

Answers

Answer:

5 · a³ · b³ · √5b

Step-by-step explanation:

Start with √(50a^6b^7).  Rewrite 50 as the product of the largest possible perfect square and a multiplier:  50 = 25 · 2.  Then √50 = 5√2.

a^6 is already a perfect square, so find its square root:  √a^6 = a^3.

b^7 = b · b^6, so √b^7 = b^3√b

Now rewrite (50(a^6) (b^7)) as √(50a^6b^7).

Then rewrite √(50a^6b^7) as 5√2 · a³ · b³ · √b.

This latter result can be simplified to 5 · a³ · b³ · √5b

This matches possible answer #1.

What are the domain and range of the piecewise function below? HELP ASAP

Answers

The domain is the set of all point where you can evaluate the function.

As you can see, the first piece is defined from -infinity to 2 (included).

The second piece is defined from 2 to 6 (excluded).

The third piece is defined from 6 (excluded) to +infinity.

So, the domain of the function is composed by all the real numbers which are not 6:

[tex](-\infty,6)\cup(6,\infty) = \mathbb{R}\setminus\{6\} = \{x \in \mathbb{R}\ :\ x\neq 6\}[/tex]

As for the range, it is the set of all values taken by the function. We can see that the first piece spans the y axis from 0 to infinity.

The second piece is constantly equal to 2, so it adds nothing.

The third piece spans the y axis from -2 to -infinity, so the range is

[tex](-\infty,-2)\cup[0,\infty) = \mathbb{R}\setminus [2,0) = \{x \in \mathbb{R}\ :\ x\geq 0\ \lor\ x<-2\}[/tex]

The domain is the set of all point where you can evaluate the function.

As you can see, the first piece is defined from -infinity to 2 (included).

The second piece is defined from 2 to 6 (excluded).

The third piece is defined from 6 (excluded) to +infinity.

So, the domain of the function is composed by all the real numbers which are not 6:

As for the range, it is the set of all values taken by the function. We can see that the first piece spans the y axis from 0 to infinity.

The second piece is constantly equal to 2, so it adds nothing.

What is amplitude?

Amplitude: The amplitude of a periodic function is the measure of its maximum displacement from its average or equilibrium position.

Period: The period of a periodic function is the distance along the x-axis between one cycle of the function and the next identical cycle.

Vertical Shift: The vertical shift (or translation) of a function is a vertical displacement of the entire graph either upward or downward.

Phase Shift: The phase shift is a horizontal displacement or translation of a function.

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

[tex]t=10\ years\\ A=\$50,000\\ r=0.043\\n=365[/tex]  

substitute in the formula above  

[tex]\$50,000=P(1+\frac{0.043}{365})^{365*10}[/tex]  

[tex]P=\$50,000/[(1+\frac{0.043}{365})^{3,650}]=\$32,526.28[/tex]
