Answer: Edgur eats 12 ounces of popcorn. Before he ate any, he had 2 pounds of popcorn. How much popcorn, in ounces, of popcorn does Edgur have now? Edgur has 20 ounces of popcorn.
Step-by-step explanation:
Pounds to ounces: 1 pound = 16 ounces.
2 * 16 = 32.
He ate 12 of those ounces. 32 - 12 = 20.
Final answer:
To solve a problem involving subtraction of pounds and ounces, convert everything to ounces, subtract, and convert back if necessary. In this example, after removing 3 pounds 5 ounces from 9 pounds 8 ounces, the remaining weight is 6 pounds 3 ounces.
Explanation:
Let's create a subtraction problem involving pounds and ounces. Imagine you have a sack of potatoes weighing 9 pounds 8 ounces, and you remove a bag of potatoes weighing 3 pounds 5 ounces. How much does the sack of potatoes now weigh?
First, we need to ensure that both weights are in the same units. We have:
Initial weight: 9 pounds 8 ounces
Weight removed: 3 pounds 5 ounces
To subtract these weights, we will convert pounds to ounces for each weight, then subtract, and finally convert back to pounds and ounces if necessary.
Convert 9 pounds to ounces: 9 × 16 = 144 ounces
Therefore, the initial weight in ounces is 144 ounces + 8 ounces = 152 ounces.
Convert 3 pounds to ounces: 3 × 16 = 48 ounces
The weight removed in ounces is 48 ounces + 5 ounces = 53 ounces.
Subtract the smaller weight from the initial weight: 152 ounces - 53 ounces = 99 ounces
Now we convert 99 ounces back to pounds and ounces. Since 1 pound is 16 ounces:
99 ÷ 16 = 6 pounds with a remainder of 3 ounces.
So, the sack of potatoes now weighs 6 pounds 3 ounces.
Line FH and line Ik are parallel lines
Which angles are corresponding angles?
Corresponding angles are the ones that occupy the same relative position where a third line intersects two other lines. If lines FH and IK are parallel, the corresponding angles are FHB and IKB; and BHJ and BKL. They are always equal in measure if the lines are parallel.
Explanation:In geometry, lines that are parallel have several corresponding angles. Corresponding angles are the angles that occupy the same relative position at each intersection where a line intersects two other lines. If lines FH and IK are parallel and intersected by another line (Let's call it line B for easier understanding), the corresponding angles would be as follows:

if logM/N = 4 and logP/N =7, what can you say about the relationship between M and P?
A. P= 3M
B. M= 3P
C. P= 1000M
D. P= 100M
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

A recipe for ricotta cheese calls for 1/2 cup of whole milk for every 1/4 cup of heavy cream. How much whole milk should be used for every one cup of heavy cream
A. 1/8 cup
B. 1/4 cup
C. 2 cups
D. 4 cups
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.
Explanation: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.) 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
marta is solving the equation s=2πrh+2πr^2 for h. which should be the result?
s/2πr-r=h
s-r/2πr=h
s-r/2π=h
s-2π/r=h
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.

It is made up of a rectangular prism and a right angled triangular prism.Also, if B is the base area of the rectangular prism (i.e. square base) and h is it's height then the volume of the Rectangular prism is:[tex]Volume=Bh[/tex]
Also, for the triangular prism the base area is halved and hence the base area of triangular prism is: B/2
Hence, the total volume of Triangular prism is: [tex]\dfrac{1}{2}Bh[/tex]
Hence, the total volume of figure is:

B) The algebraic function has a lower minimum value.
C) The graphed function has a greater maximum value.
D) The graphed function has a lower minimum value.
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.
