To convert George the giraffe's height from feet to inches, multiply 18 feet by the conversion factor of 12 inches per foot, resulting in George being 216 inches tall.

If George the giraffe is 18 feet tall and you want to convert his height to inches, you need to know that one foot is equal to 12 inches. To find out how many inches tall George the giraffe is, you multiply his height in feet (18 feet) by the number of inches in one foot.

Here's the calculation step by step:

Therefore, George the giraffe is 216 inches tall.

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:

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

Answer:

The line intercepts the y-axis and [tex]y = 8[/tex]

Step-by-step explanation:

The intersection on the y-axis of a line is found to be [tex]x = 0[/tex].

That is, the intercept with the y-axis is the value of the function when x is equal to zero.

In this case we know the following points of the function:

x  : -2    -1    0    1     2    3

y  : 16    12   8    4    0   -4

Note that when [tex]x = 0[/tex] then [tex]y = 8[/tex].

Therefore the line intercepts the y-axis and [tex]y = 8[/tex]

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:

a.) 1.38 seconds

b.) 17.59ft

Step-by-step explanation:

h(t) = -16t^2 + 22.08t + 6

if we were to graph this, the vertex of the function would be the point, which if we substituted into the function would give us the maximum height.

to find the vertex, since we are dealing with something called "quadratic form" ax^2+bx+c, we can use a formula to find the vertex

-b/2a

b=22.08

a=-16

-22.08/-16, we get 1.38 when the minuses cancel out. since our x is time, it will be 1.38 seconds

now since the vertex is 1.38, we can substitute 1.38 into the function to find the maximum height.

h(1.38)= -16(1.38)^2 + 22.08t + 6 -----> is maximum height.

approximately = 17.59ft -------> calculator used, and rounded to 2 significant figures.

for c the time can be equal to (69+sqrt(8511))/100, as the negative version would be incompatible since we are talking about time. or if you wanted a rounded decimal, approx 1.62 seconds.

Answer:

a) [tex]h(t)=-16(t-0.69)^2)+13.62[/tex]

b)The maximum height is 13.62 feet.

c) 1.84 seconds

Step-by-step explanation:

The function that models the height in feet of the hammer above the ground is

[tex]h(t)=-16t^2+22.08t+6[/tex]

Factor  -16 as shown;

[tex]h(t)=-16(t^2-1.38t)+6[/tex]

Add and subtract  the square of half the coefficient of t.

[tex]h(t)=-16(t^2-1.38t+(-0.69)^2)--16(-0.69)^2+6[/tex]

[tex]h(t)=-16(t^2-1.38t+(-0.69)^2)--16(-0.69)^2+6[/tex]

Rewrite the first three terms as a perfect square trinomial;

[tex]h(t)=-16(t-0.69)^2)+13.62[/tex]

This function is now in the form;

[tex]h(t)=a(t-h)^2)+k[/tex]

where (h,k)=(0.69,13.62)

This implies that; the hammer reached its maximum height at t=0.69 seconds.

b) The maximum height is the y-value of the vertex.

The maximum height is 13.62 feet.

c) To answer this question we need to find the difference between the  x-intercepts.

[tex]h(t)=-16t^2+22.08t+6[/tex]

a=-16,b=22.08,c=6

[tex]t_2-t_1=\sqrt{(t_1+t_2)^2-4t_1t_2}[/tex]

[tex]t_2-t_1=\sqrt{(\frac{-b}{a})^2-4(\frac{c}{a})}[/tex]

[tex]t_2-t_1=\sqrt{(\frac{-22}{-16})^2-4(\frac{-6}{-16})  }=1.84[/tex]

Hence the hammer was in the air for 1.84 seconds

The simplified value of the expression [tex]\frac{27^2}{27 ^{4/3}}[/tex]  using properties of exponents is 3² or 9.

Given Expression: [tex]\frac{27^2}{27 ^{4/3}}[/tex]

To Simplify the expression, use the following Exponents properties

Now, let's factorize the number of prime factors

27 = 3 x 3 x 3 or 3³

So, the Expression [tex]\frac{27^2}{27 ^{4/3}}[/tex] can  be written as

[tex]\frac{27^2}{27 ^{4/3}}[/tex] = [tex]\frac{(3^3)^2}{(3^3)^{4/3}}[/tex]

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.

Step-by-step explanation:

Part A:

Like Pasta / Like Rice: A = 20

Like Rice / Do not like Pasta: B = 60

Total: C = 80

Do not like rice / Like Pasta: D = 40

Do not like rice & Pasta: E = 80

Total F = 120

Total G = 60

Total H = 140

Total I = 200

Part B: Using the rule of three:

If 200 represents 100%, then how much 80 represents?

(80 * 100) / 200 = 40%

40% did not like pasta nor rice.
