Answer:A
Step-by-step explanation:
A ratio shows us the number of times a number contains another number. The correct option is C.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that a recipe calls for 3 cups of pecans for every 5 cups of walnuts. Therefore, the ratio of pecans to walnuts is,
Pecans/ Walnuts = 3 cups / 5 cups
Now, the number of cups of pecans that should be added to 8 cups of walnuts is,
Pecans/ Walnuts = 3 cups / 5 cups
Pecans/ 8 cups = 3 cups / 5 cups
Pecans = (8×3)/5 cups
Pecans = 4.8 cups
Hence, the correct option is C.

Definition of equilateral triangle
Answer:
An equilateral triangle has all its 3 angles the same.
Hope this helped. :)
Equilateral triangle:
An equilateral triangle is a triangle having three equal sides, or what is sometimes referred to as a "regular" triangle. Because all three sides of an isosceles triangle are equal, an equilateral triangle is a particular case of an isosceles triangle.
Additionally, an equilateral triangle has three equal angles of 60 degrees.
Equilateral Triangle Perimeter:
In geometry, any polygon's perimeter is equal to the sum of its sides. The perimeter of an equilateral triangle is equal to the sum of its three sides.
In the event that ABC is an equilateral triangle, then its perimeter is;
Perimeter = AB + BC + AC
P = a + a + a
P = 3a [where "a" is the triangle's side length.]

Write the quadratic equation whose roots are - 5 and -4, and whose leading coefficient is 3.
Answer:
The quadratic equation is
3x^2+ 27x + 60
Step-by-step explanation:
Here, we have the roots -5 and -4 and the leading coefficient of 3
Mathematically, we simply have this done to the roots;
x = -5 implies x+ 5
x = -4 implies x + 4
The product of this two will be;
(x + 5)(x + 4)
= x^2 + 5x + 4x + 20
= x^2 + 9x + 20
we add the leading coefficient
that would be;
3(x^2 + 9x + 20)
= 3x^2 + 27x + 60

Answer:
A: [tex]\frac{1}{2\sqrt{x-1} }[/tex]
B:[tex]\frac{1}{4\sqrt[4]{x^{3} } }[/tex]
c: 2x
Step-by-step explanation:
To find the derivative of x raised to the nth power we use the following template
[tex]x^{n}=nx^{n-1}[/tex]
Something else to keep in mind is that
[tex]\sqrt[n]{x^{y}}=x^{y/n}[/tex]
So knowing this we can rewrite a as follows
[tex]\sqrt{x-1} =(x-1)^{1/2}[/tex]
so we can use the template above and get
[tex]\frac{1}{2}(x-1)^{.5-1}[/tex]
So that simplifies to
[tex]\frac{1}{2}*(x-1)^{-\frac{1}{2}[/tex]
[tex]\frac{(x-1)^{-.5}}{2}[/tex]
[tex]\frac{1}{2\sqrt{x-1} }[/tex]
B: Same kind of deal here
[tex]\sqrt[4]{x}=x^{\frac{1}{4} }[/tex]
[tex]\frac{1}{4} *x^{\frac{1}{4}-1}[/tex]
[tex]\frac{x^{-\frac{3}{4}}}{4} =\frac{1}{4\sqrt[4]{x^{3} } }[/tex]
C: this one is by far the easiest because the derivative of a constant is 0 so we can just apply the same template from before and get

Answer:
X=48
Step-by-step explanation:
x^2+y^2=z^2
but in this case it's z^2-y^2=x^2
so 73^2= 5329
and 55^2=3025
5329-3025=2304
Square Root of 2304 is 48, meaning X=48

A line passes through the points (0, 14) and (18, 15) . What is its equation in slope-intercept form?
Answer:
y= 1/18x + 14
Step-by-step explanation:
Well we can first right the equation like : to find the slope
14- 15
____ = -1/-18 = 1/18
0-18
Now we know the slope is 1/18
we can substitute one point in the equation and the slope to find the equation
let's take 0,14
14= 1/18 ( 0 ) + b
14=b
so b= 14
the y-intercept is 14
the equation is
y= 1/18x + 14

Step-by-step explanation: Draw a line through the apparent center of the scattered dots. See where that line intersects 9 in the time scale (x-axis numbers) and the dollars earned scale (y-axis numbers)
It could be 50 or 55, but since there are a few more dots below the apparent midline, it may be best to use the lower estimate.

Felix surrounds a 12 in. by 8 in. photo with a frame that is x inches wide. Which quadratic function represents the combined area A of the picture and the frame?
A. A(x) = x^2 + 20x + 96
B. A(x) = x^2 + 40x + 96
C. A(x) = 4x^2 + 20x + 96
D. A(x) = 4x^2 + 40x + 96
Answer:
D: A(x) = 4x² + 40x + 96
Step-by-step explanation:
Dimensions of photo is;
Length; L = 12 inches
Width; W = 8 inches
Now, this picture is surrounded by a frame that is "x" inches wide. Thus, new dimensions are;
L_new = 12 + x + x = 2x + 12
W_new = 8 + x + x = 2x + 8
New area is;
A_new = (2x + 12) × (2x + 8)
A_new = 4x² + 24x + 16x + 96
A_new = 4x² + 40x + 96

Over what interval is f(x) negative? Justify your answer.
Answer in interval notation is (-3, 1)
This is the same as saying -3 < x < 1
=====================================================
Explanation:
Since y = f(x), this means we're looking for points on the red curve such that they have a negative y coordinate. Visually, we're looking for points that are below the horizontal x axis.
These points are shown in the diagram below. I've marked the section we're after in blue. This blue section spans from x = -3 to x = 1. We exclude both endpoints because each x value leads to f(x) = 0, but we want f(x) values smaller than zero.
