Marni has 24 ounces of walnuts. she needs 14 ounces for one recipe and 1/2 pounds for another. how many total ounces does she need to make her recipes?
The total ounces she needs to make her recipes is 22 ounces
Calculating quantityFrom the question, we are to determine how many total ounces Marni needs to make her recipe
From the given information,
Marni has 24 ounces of walnuts
Also,
She needs 14 ounces for one recipe
and
1/2 pounds for another
First, we will convert 1/2 pounds to ounces
NOTE: 1 pound = 16 ounces
∴ 1/2 pound = 8 ounces
Then, we can rewrite that
She needs 14 ounces for one recipe
and
8 ounces for another
The total ounces she needs to make her recipes = 14 ounces + 8 ounces
The total ounces she needs to make her recipes = 22 ounces
Hence, the total ounces she needs to make her recipes is 22 ounces

A deck of cards contains 52 different cards a card is drawn at random what is the probability that the card drawn is a queen
Answer: 4/52 = 1/13
Step-by-step explanation: We know that a full deck of cards is 52 and there are 4 suits in a deck. Which means that there are 4 queens in each deck. Now, we can add that up together which gives us 4/52, and can be simplified down to 1/13 because 4/52 isn't the smallest we can get our fraction.
Hope this helps :)

Answer:
x = 80
Step-by-step explanation:
The diagram shows that arc AB is 80 degrees, and the measure of an arc defined as being equal to the central angle(the minor angle of the arc). Because the arc AB is 80, the central angle x is 80 degrees as well. Although if point O wasn't at the center of the circle, x might not be 80.

Problem 9
The instructions aren't stated anywhere, but I'm assuming your teacher wants you to find the equation of each parabola.
The vertex here is (h,k) = (-6,-4) which you have correctly determined.
This means
[tex]y = a(x-h)^2 + k\\\\y = a(x-(-6))^2 +(-4)\\\\y = a(x+6)^2 - 4\\\\[/tex]
Next we plug in one of the other points on the parabola. We cannot pick the vertex again. Let's pick the point (-4,0) which is one of the x intercepts. We'll do this to solve for 'a'
[tex]y = a(x+6)^2 - 4\\\\0 = a(-4+6)^2 - 4\\\\0 = a(2)^2 - 4\\\\0 = a(4) - 4\\\\0 = 4a-4\\\\4a-4 = 0\\\\4a = 4\\\\a = 4/4\\\\a = 1\\\\[/tex]
This means
[tex]y = a(x+6)^2 - 4\\\\y = 1(x+6)^2 - 4\\\\y = (x+6)^2 - 4\\\\[/tex]
represents the equation of the parabola in vertex form.
Answer: [tex]y = (x+6)^2 - 4\\\\[/tex]========================================================
Problem 10
The vertex is (h,k) = (-2,-6)
So,
[tex]y = a(x-h)^2 + k\\\\y = a(x-(-2))^2 + (-6)\\\\y = a(x+2)^2 - 6\\\\[/tex]
Now plug in another point on the parabola like (-1,-8) and solve for 'a'
[tex]y = a(x+2)^2 - 6\\\\-8 = a(-1+2)^2 - 6\\\\-8 = a(1)^2 - 6\\\\-8 = a(1) - 6\\\\a-6 = -8\\\\a = -8+6\\\\a = -2\\\\[/tex]
Answer: [tex]y = -2(x+2)^2 - 6\\\\[/tex]For each equation, you could optionally expand things out to get it into y = ax^2+bx+c form, but I think it's fine to leave it as vertex form.
Answer:
[tex]\textsf{9)} \quad y=(x+6)^2-4[/tex]
[tex]\textsf{10)} \quad y=-2(x+2)^2-6[/tex]
Step-by-step explanation:
Vertex form of a parabola:
[tex]y=a(x-h)^2+k[/tex] where (h, k) is the vertex
Question 9From inspection of the graph, the vertex is (-6, -4)
[tex]\implies y=a(x+6)^2-4[/tex]
To find [tex]a[/tex], substitute the coordinates of a point on the curve into the equation.
Using point (-4, 0):
[tex]\implies a(-4+6)^2-4=0[/tex]
[tex]\implies a(2)^2-4=0[/tex]
[tex]\implies 4a=4[/tex]
[tex]\implies a=1[/tex]
Therefore, the equation of the parabola in vertex form is:
[tex]y=(x+6)^2-4[/tex]
Question 10From inspection of the graph, the vertex is (-2, -6)
[tex]\implies y=a(x+2)^2-6[/tex]
To find [tex]a[/tex], substitute the coordinates of a point on the curve into the equation.
Using point (-1, -8):
[tex]\implies a(-1+2)^2-6=-8[/tex]
[tex]\implies a(1)^2-6=-8[/tex]
[tex]\implies a-6=-8[/tex]
[tex]\implies a=-2[/tex]
Therefore, the equation of the parabola in vertex form is:
[tex]\implies y=-2(x+2)^2-6[/tex]

Which values are solutions to the inequality below? Check all that apply.
x^2 > 16
A. 4
B. -6
C. -1
D. 5
Answer:
B. -6 and D. 5
Step-by-step explanation:
x^2 - 16 > 0
y = (x - 4)(x + 4) > 0
The critical point are x = -4 and x = 4
When x < -4, y > 0
When x > 4, y > 0
When -4 < x < 4, y < 0
When x = -4 and x = 4 , y = 0.
So the values that apply are

Find the area of the circle
r = 6 ft
If the radius of the circle is 6 feet. Then the area of the circle will be 113.097 square feet.
What is a circle?It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.
The radius of the circle is 6 feet.
Then the area of the circle will be
Area = πr²
where r is the radius of the circle. Then we have
Area = π × 6²
Area = 36π
Area = 113.097 square feet

[tex]\textsf{Given}:y=\log (x \sin x)[/tex]
[tex]\textsf{Let }u=x \sin x \implies y=\log(u)[/tex]
Using the product rule, differentiate y with respect to [tex]u[/tex]:
[tex]\textsf{If }y=\log(u) \implies \dfrac{dy}{du}=\dfrac{1}{u}\implies \dfrac{dy}{du}=\dfrac{1}{x \sin x}[/tex]
----------------------------------------------------------------------------------------
Differentiate [tex]u=x \sin x[/tex] with respect to x using the product rule:
[tex]\implies \textsf{Let }f(x)=x \implies f'(x)=1[/tex]
[tex]\implies \textsf{Let }g(x)=\sin x \implies g'(x)=\cos x[/tex]
[tex]\implies \dfrac{du}{dx}=x \cos x + \sin x[/tex]
----------------------------------------------------------------------------------------
Use the chain rule to differentiate y with respect to x:

[tex]\implies \dfrac{dy}{dx}=\dfrac{1}{x \sin x} \times (x \cos x + \sin x)[/tex]

Answer:
[tex]\displaystyle \large{\dfrac{d}{dx}[\log(x\sin x)] = \dfrac{1}{x\ln 10} + \dfrac{\cot x}{\ln 10}}[/tex]
Step-by-step explanation:
Given:
[tex]\displaystyle \large{y=\log (x\sin x)}[/tex]
Recall the (common) logarithmic differentiation & chain rules:
[tex]\displaystyle \large{\dfrac{d}{dx}[\log (u)] = \dfrac{u'}{u\ln 10}}[/tex]
Let [tex]\displaystyle \large{u=x\sin x}[/tex] then:
[tex]\displaystyle \large{\dfrac{d}{dx}[\log(x\sin x)] = \dfrac{(x\sin x)'}{x\sin x \ln 10}}[/tex]
Recall product rules:
[tex]\displaystyle \large{[f(x)g(x)]' = f'(x)g(x)+f(x)g'(x)}[/tex]
Hence:
[tex]\displaystyle \large{\dfrac{d}{dx}[\log(x\sin x)] = \dfrac{(x)'\sin x + x(\sin x)'}{x\sin x \ln 10}}\\\\\displaystyle \large{\dfrac{d}{dx}[\log(x\sin x)] = \dfrac{\sin x + x\cos x}{x\sin x \ln 10}}\\\\\displaystyle \large{\dfrac{d}{dx}[\log(x\sin x)] = \dfrac{\sin x}{x \sin x \ln 10} + \dfrac{x \cos x}{x\sin x \ln 10}}\\\\\displaystyle \large{\dfrac{d}{dx}[\log(x\sin x)] = \dfrac{1}{x\ln 10} + \dfrac{\cot x}{\ln 10}}[/tex]
From above, recall that:
[tex]\displaystyle \large{\dfrac{d}{dx}(\sin x) = \cos x}\\\\\displaystyle \large{\dfrac{A\pm B}{C} = \dfrac{A}{C} \pm \dfrac{B}{C}}\\\\\displaystyle \large{\dfrac{\cos x}{\sin x} =\cot x}[/tex]
Hence, the answer is:
[tex]\displaystyle \large{\dfrac{d}{dx}[\log(x\sin x)] = \dfrac{1}{x\ln 10} + \dfrac{\cot x}{\ln 10}}[/tex]
Triangle ABC is dilated by a scale factor of 1.5 to create triangle A'B'C'. Which of
the following it not a true statement?
A. The image is larger than the pre-image.
B. The orientation of triangle ABC is preserved.
C. Segment AB is congruent to segment A'B'.
D. The angle measures in triangle ABC are equal to the angle measures in triangle
A'B'C'.
Answer:
C. Segment AB is congruent to segment A'B'.
Step-by-step explanation:
Since ABC is being dilated by 1.5, it means that A'B'C will be bigger than ABC.
So, since A'B'C will be bigger than ABC, it sides will also be bigger than the sides in ABC.
And since the sides/segments are bigger than the original, they are not congruent (congruent means equal).

To find x°
From above figure, angle AOC = angle AOB + angle BOC
Now angle AOB = 53°, angle AOC = 90°
90° = 53° + angle BOC

if the box is to be made out of wood that costs $4 per square foot, which of your designs would be less expensive to produce? Explain.
The second box is less expensive to make since it has a smaller surface area and hence requires less wood to construct the sides.
What is a cuboid?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape.
Here some data is not given, so we are assuming the volume of the box is 24 cubic feet.
If the volume is 24 cubic feet, the box's three dimensions must multiply to equal 24.
We can make two designs:
2 × 2 × 6 and 2 × 3 × 4.
Now, finding the surface area for each design.
First box
SA = 2wl + 2wh + 2hl
SA = 2×2×2 + 2×2×6 + 2×2×6
SA = 56 square feet
Second box
SA = 2×2×3 + 2×2×4 + 2×3×4
SA = 52 square feet
At $4 per square foot
For 56 ft², the price is $224
For 52 ft², the price is $208
Thus, the second box is less expensive to make since it has a smaller surface area and hence requires less wood to construct the sides.
