Answer:
6.2
Step-by-step explanation:
(A) The ratio of the model to the surface area of original 81 : 4.
(B) The ratio of the height of the model to the height of the original 9 : 2.
(C) The ratio of the volume of the model to the volume of the original 729 : 8.
What is ratio?Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
The scale factor = 2 : 9
(A)
The surface area of the model to the surface area of original
= (9)² : (2)²
= 81 : 4
= 20.25
(B)
The ratio of the height of the model to the height of the original
= 9 / 2
= 4.5
(C)
The ratio of the volume of the model to the volume of the original
= (9)³ : (2)³
= 729 : 8
= 91.125

Answer: 12/40
Step-by-step explanation:
Basically you gotta add up all of the number of students who are getting each of the food, then you have to put the number of student that want a hamburger. You also have to create the fraction which is 12/40
Step-by-step explanation:
Total = 8 + 12 + 14 + 6 = 40
The amount of people who had a hamburger is = 12
So twelve over forty will be the probability of the next student who picks a hamburger

Answer:
75.4m²
Step-by-step explanation:
The shape shown is a cylinder
The volume of a cylinder can be calculated using this formula:
[tex]V=\pi r^2h[/tex]
where r = radius and h = height
The cylinder shown has a radius of 2m and a height of 6m
Using this information we plug in the values into the formula
[tex]V=\pi 2^26\\2^2=4\\4\pi =12.56637\\12.56637*6=75.39822[/tex]
So the area of the cylinder is 75.39822
Our final step is to round to the nearest hundredth
The final answer would be 75.4m²
Ms. Geiger made 100 cupcakes. 60/100 were chocolate, 2/10 were vanilla, and the rest were red velvet. What fraction of the cupcakes were red velvet?
Answer:
2/10
Step-by-step explanation:
Ms. Geiger made 100 cupcakes.
a) Number of chocolate
60/100 were chocolate
= 60/100 × 100 = 60 chocolate cup cakes
b) Number of vanilla
2/10 were vanilla
Hence:
2/10 × 100 = 20 vanilla cup cakes
c) the rest were red velvet.
Number rod red velvet = 100 - (60 + 20)
= 100 - 80
= 20 velvet cupcakes
What fraction of the cupcakes were red velvet?
Converting to fraction
Number of velvet cupcakes/Total number of cakes
= 20/100
= 2/10

According to the figure,
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
What is the tangent of the circle?It is the line which intersects the circle exactly at one point.
(a) Find m ∠AOC
Sum of three angles of a triangle is = 180°
So, in Triangle AOC = 180°
∠A + ∠O + ∠C = 180°
See in Image, ∠A and ∠C are 90° and 32°
∠A + ∠O + ∠C = 180°
We can substitute these values,
∠O = 180 - ∠A - ∠C
∠O = 180 - 90 - 32
∠O = 58°
∠AOC = 58°
(b) ∠BDC is a parallelogram,
So,
Opposite angle is equal,
∠BDC = ∠ABC
∠BDC = 32° ( since ∠ABC = 32° )
(c) Find m ∠ACD
Sum of three angles of a triangle is = 180°
So, in Triangle ACD = 180°
∠A + ∠C + ∠D = 180°
See in Image, ∠A and ∠D are 90° and 32°
∠A + ∠D + ∠C = 180°
We can substitute these values,
∠C = 180 - ∠A - ∠D
∠C = 180 - 90 - 32
∠C = 58°
Now,
∠ACD = 90 + 58
∠ACD = 148°
Therefore,
The circumference of tangent to the circle,
(a) ∠AOC = 58°
(b) ∠BDC = 32°
(c) ∠ACD = 148°

y = [tex]\frac{-5}{4}[/tex]x + 3
Step-by-step explanation:As shown in the graph, the line is a straight line. Therefore, the general equation of a straight line can be employed to derive the equation of the line.
The general equation of a straight line is given by:
y = mx + c or -------------(i)
y - y₁ = m(x - x₁) -----------------(ii)
Where;
y₁ is the value of a point on the y-axis
x₁ is the value of the same point on the x-axis
m is the slope of the line
c is the y-intercept of the line.
Equation (i) is the slope-intercept form of a line
Steps:
(i) Pick any two points (x₁, y₁) and (x₂, y₂) on the line.
In this case, let;
(x₁, y₁) = (0, 3)
(x₂, y₂) = (4, -2)
(ii) With the chosen points, calculate the slope m given by;
m = [tex]\frac{y_2 - y_1}{x_2-x_1}[/tex]
m = [tex]\frac{-2-3}{4-0}[/tex]
m = [tex]\frac{-5}{4}[/tex]
(iii) Substitute the first point (x₁, y₁) = (0, 3) and m = [tex]\frac{-5}{4}[/tex] into equation (ii) as follows;
y - 3 = [tex]\frac{-5}{4}[/tex](x - 0)
(iv) Solve for y from (iii)
y - 3 = [tex]\frac{-5}{4}[/tex]x
y = [tex]\frac{-5}{4}[/tex]x + 3 [This is the slope intercept form of the line]
Where the slope is [tex]\frac{-5}{4}[/tex] and the intercept is 3

A square picture with a side length of 4 inches needs to be enlarged. The final area needs to be 81 square inches. Which equation can be used to solve for x, the increase in side length of the square in inches? x2 + 4x – 81 = 0 x2 + 4x – 65 = 0 x2 + 8x – 65 = 0 x2 + 8x – 81 = 0
Given the initial side length = 4in
Initial area = L²
L is side length of the square
Initial area = 4²
Initial area = 16 square inches
Area of the enlarged square = 81 square inches
To get the constant term of the expression, we will find the difference in the areas
Difference = 85 - 16
Difference = 65 square units
The coefficient of x will be the 2 *initial area of the square
Given the standard form of an expression as
ax^2 + bx + c
a = 1, b = 2*4 = 8, c = -65
Substitute
x^2 + 8x - 65
This gives the required expression
