Answer: $0.25

Step-by-step explanation:

Let x be the total money was in her wallet and m be the cost of each petunia,

From the given table , the money left in wallet after purchasing 2 petunia =$6.50

Then we have the following equation :-

[tex]6.50=x-2m-----(1)[/tex]

Also, the money left in wallet after purchasing 8 petunia =$5

Then, we have

[tex]5=x-8m---------(2)[/tex]

Subtracting (2) from (1) , we get

[tex]6.50-5=-2m-(8m)\\\\\Rightarrow\ -2m+8m=1.50\\\\\Rightarrow\ 6m=1.50\\\\\Rightarrow\ m=\dfrac{1.50}{6}=0.25[/tex]

Answer:

The answer is option A.

Answer:

C. 2 cups

Step-by-step explanation:

So since it says for every 1/2 cup of whole milk, you need 1/4 of heavy cream, that means you will need twice as much whole milk as you do heavy cream.

So for every one cup of heavy cream, that means you need 2 cups of whole milk.

This is because 1/2 is twice as much as 1/4.

To scale up the given ratio of 1/2 cup of whole milk to 1/4 cup of heavy cream to 1 cup of cream, you need to multiply the quantity of milk by 4. This gives you 2 cups of milk for 1 cup of cream.

The question asks us to calculate the quantity of whole milk that should we used for every cup of heavy cream, based on a given ratio. The ratio given is 1/2 cup of milk for every 1/4 cup of cream. Ratios can be scaled up or down while keeping the same relationship between quantities. In this case, we want to know how much milk to use for 1 cup of cream. Since 1 cup is 4 times larger than 1/4 cup, we simply multiply the quantity of milk by 4 as well, which gives us 1/2 cup * 4 = 2 cup. Hence, the answer is C. 2 cups of milk should be used for every cup of heavy cream.

ANSWER

A) The algebraic function has a greater maximum value.

EXPLANATION

The given function is

[tex]f(x) = - 8 {x}^{2} + 4x + 2[/tex]

This can be rewritten as:

[tex]f(x) = - 8( {x - \frac{1}{4} })^{2} + \frac{5}{2} [/tex]

The maximum value of this function is 2.5

The maximum value of the graph is less that zero.

This means that that the maximum value of the algebraic function is greater than the maximum value of the graph.

Answer:

Option A.

Step-by-step explanation:

Algebraically expressed function is f(x) = -8x² + 4x + 2

As we know in a quadratic equation f(x) = ax² + bx + c, if a is negative then the vertex will be maximum.

and the maximum value will be represented by [tex]c-\frac{b^{2}}{4a}[/tex]

From the given quadratic equation

a = -8

b = 4 and c = 2

Now we place these values in the equation.

Maximum = [tex]2-\frac{4^{2}}{4(-8)}[/tex]

                = 2 + 0.5

                = 2.5

From the graph attached we can easily conclude that vertex of the parabola is less than 0.5

Therefore, algebraic function has the greater maximum value.

Option A. is the answer.

Answer:

33

Step-by-step explanation:

Each holds 2.5*12 = 30 eggs.

1000/30 = 33.333333

So he fills 33 flats.

The number of flats he could fill is 33

Peterson needed to pack 1000 eggs into flats that held 2 1/2 dozen eggs. To find out how many flats he could fill, we need to calculate the total dozen eggs in 1000 and then divide by 2.5 dozen since each flat holds 2 1/2 dozen eggs.  One dozen equals 12 eggs. Therefore, 1000 eggs would be equivalent to 1000/12 = 83.33 dozen. To find the number of flats, we divide the total dozen eggs by the capacity of each flat in dozen: 83.33 dozen / 2.5 dozen = 33.33. This means Peterson can completely fill 33 flats, with a partial amount of eggs left over not sufficient to fill another flat completely.

Answer: First option.

Step-by-step explanation:

Marta needs to subtract [tex]2\pi r^2[/tex] from  both sides of the equation:

[tex]s=2\pi rh+2\pi r^2[/tex]

[tex]s- 2\pi r^2=2\pi rh+2\pi r^2- 2\pi r^2[/tex]

[tex]s- 2\pi r^2=2\pi rh[/tex]

Now she needs to divide both sides of the equation by [tex]2\pi r[/tex], then:

[tex]h=\frac{s- 2\pi r^2}{2\pi r}[/tex]

Rewriting:

[tex]h=\frac{s}{2\pi r}-\frac{2\pi r^2}{2\pi r}[/tex]

Simplifying, she should get:

[tex]h=\frac{s}{2\pi r}-r[/tex]

This matches with the first option.

Answer:

[tex]\frac{s}{2\pi r}-r=h[/tex]

Step-by-step explanation:

Given equation is [tex]s=2\pi rh+2\pi r^2[/tex].

Now we need to solve this equation for "h" and match with the given choices to find the correct choice.

[tex]s=2\pi rh+2\pi r^2[/tex]

[tex]s-2\pi r^2=2\pi rh[/tex]

[tex]2\pi rh=s-2\pi r^2[/tex]

[tex]h=\frac{s-2\pi r^2}{2\pi r}[/tex]

[tex]h=\frac{s}{2\pi r}-\frac{2\pi r^2}{2\pi r}[/tex]

[tex]h=\frac{s}{2\pi r}-r[/tex]

[tex]\frac{s}{2\pi r}-r=h[/tex]

Hence first choice [tex]\frac{s}{2\pi r}-r=h[/tex] is correct choice.

Answer:

C. P= 1000M

Step-by-step explanation:

[tex]log(\frac{M}{N} )=4[/tex]

Using the quotient rule of logs we can write:

log(M) - log(N) = 4

or

log(M) - 4 = log(N)                                       (Equation 1)

[tex]log(\frac{P}{N} )=4[/tex]

Using the quotient rule of logs we can write:

log(P) - log(N) = 7

or

log(P) - 7 = log(N)                                         (Equation 2)

Comparing equation 1 and 2, we can write:

log(M) - 4 = log(P) - 7

-4 + 7 = log(P) - log(M)

log(P) - log(M) = 3

[tex]log(\frac{P}{M} )=3[/tex]

Converting the log to exponential form we get:

[tex]\frac{P}{M}=10^{3}\\\\\frac{P}{M}=1000\\\\P=1000M[/tex]

Thus, option C gives the correct answer.

Final answer:

The relationship between M and P is that P is 1000 times greater than M; hence, the correct option is P = 1000M.

Explanation:

Given the two equations log(M/N) = 4 and log(P/N) = 7, we need to find the relationship between M and P.

To understand this relationship, we use the property of logarithms that equates to a multiplication by 10 for each unity increase in logarithmic value.

From the first equation, M/N = 10⁴, and from the second equation, P/N = 10⁷. Simplifying these, M = 10⁴ N and P = 10⁷ N.

To find the relationship between M and P, we can divide the equation for P by the equation for M:

P/M = (10⁷ N) / (10⁴ N) = 10³ = 1000.

Therefore, P is 1000 times M, which means P = 1000M
