The mixed fraction equations which are true are C , D and E
What are Mixed Numbers?A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
Given data ,
Let the mixed number equation be represented as A
Now , the value of A is
To solve each equation, we can convert mixed numbers to improper fractions, then multiply the fractions, and simplify the result if possible.
A)
A = 5/6 × 4 2/3 = (5/6) × (4×3 + 2)/3
A = (5/6) × 14/3 = 35/9, which is not equal to 3 8/9.
Therefore, equation A is false.
B)
B = 1 1/10 × 8 3/5 = (11/10) × (43/5)
B = 473/50 = 9 23/50, which is not equal to 9 1/2.
Therefore, equation B is false.
C)
C = 3 2/9 × 2 1/6 = (29/9) × (13/6)
C = 377/54 = 6 53/54
Therefore, equation C is true.
D)
D = 2 3/7 × 1 7/8 = (17/7) × (15/8)
D = 255/56 = 4 23/56 = 2 3/8
Therefore, equation D is true.
E)
E = 7/12 × 4 = 7/3 = 2 1/3
Therefore, equation E is true.
Hence , the equations that are true are C, D, and E

Given the funtion f(x) =g(x-3)+2, describe transformation of f(x) on a coordinate plane relative to g(x). Please show work...
Answer:
Given function:
f(x) =g(x-3)+2This is a translation right and up:
h(x) = g(x - 3) indicates horizontal translation of 3 units rightf(x) = h(x) + 2 indicates vertical translation of 2 units upPQ and QR are 2 sides of a regular 12-sided polygon.
PR is a diagonal of the polygon.
Work out the size of angle PRQ.
You must show your working.
The size of the angle m∠PRQ for the polygon is equal to 15°
How to calculate for the angle PQR using interior angle of the polygonTo calculate the sum of interior angles of a polygon, you can use the following formula:
Sum of interior angles = (n-2) x 180 degrees
Where "n" represents the number of sides (or vertices) of the polygon.
Given the 12 sided polygon;
(12 - 2) × 180 = 1800
one interior angle = 1800/12 = 150°
The angle PQR is a base angle of the Isosceles triangle ∆PQR with one interior angle of the 12-sided polygon so;
m∠PRQ = (180 - 150)/2
m∠PRQ = 15°.
Therefore, the size of the angle m∠PRQ for the polygon is equal to 15°

Anita needs to construct ten cones for a class project. How many square feet of material will she need? Use 3.14 for π. Enter your answer in the box. Th radius is 6 ft and the height is 12 ft.
Assuming that Anita needs hollow right circular cones, we are solving for its lateral surface area, which is given by the formula πr√ (h²+r²), where r is the radius and h is the height.
r = 6 ft / 2 = 3 ft
Solving for the lateral surface area of one cone:
LSA = (3.14) (3) [√ (12²+3²) ] = 116.52 sq ft.
Since she needs 10 cones:
10 * 116.52 sq. ft = 1,165.2 sq ft.
She will need 1,165.2 sq ft of material.

b Pete won the first heat in 13 minutes 39 seconds. Jacob won the second heat in 14 minutes 16 seconds. Who ran faster? By how much? t
In accordance with the research problem we were given, Pete outran Jacob by 37 seconds.
A second of angle is what?Minutes are the 60 equal pieces that make up each degree. Thus, 7 to 8 inches can also be written as seven degrees and thirty minutes, or seven°30'. For example, 2 ° 5 minutes and 30 seconds are represented by the notation 2° 5' 30 since each minutes is further subdivided into 60 equal seconds.
Then, we have Pete's time: First, we convert minutes into seconds. 13 minutes and 39 seconds is equal to 13 * 60 + 39, or 819 seconds.
Jacob's period: 14 minutes and 16 sec. = 14 * 60 + 16 sec. = 856 sec.
Jacob outpaced Pete by 856 – 819 = 37 seconds.
Pete ran 37 seconds faster as a result.

Mark buys Apple stock for $100 and its value increases by a factor of 1.5 each week. Which equation represents the relationship between the number of weeks past since purchase, t, and the current value of the stock, V?
Given:
Initial value of the stock = $100
Growth factor = 1.5 each week.
To find:
The equation that represents the relationship between the number of weeks past since purchase and the current value of the stock.
Solution:
Let V be the current value of the stock after t week.
The exponential growth model is:
[tex]V=ab^t[/tex]
Where, a is the initial value of stock, b is the weekly growth factor, t is the number of weeks.
Substituting [tex]a=100,b=1.5[/tex], we get
[tex]V=100(1.5)^t[/tex]
Therefore, the required equation for the given situation is [tex]V=100(1.5)^t[/tex].

Write the exact value of the side length of each square. If the value is not a whole number, estimate the length.
area exact side length estimite side length
100 square units ------ units
95 square units bettween ----- and -----
36 square units -------units
30 square units bettween ----- and -----
Given:
The area of the squares are given.
To find:
The exact side length or estimate side length of the square.
Solution:
We know that, the area of a square is
[tex]A=a^2[/tex]
Where, a is the side length of the square.
[tex]a=\sqrt{A}[/tex]
Area of the square is 100 square units. So, the side length is:
[tex]a=\sqrt{100}[/tex]
[tex]a=10[/tex]
Therefore, the side length is 10 units.
Area of the square is 95 square units. So, the side length is:
[tex]a=\sqrt{95}[/tex]
It is not exact. We know that [tex]\sqrt{81}<\sqrt{95}<\sqrt{100}[/tex].
Therefore, the side length is between 9 and 10.
Area of the square is 36 square units. So, the side length is:
[tex]a=\sqrt{36}[/tex]
[tex]a=6[/tex]
Therefore, the side length is 6 units.
Area of the square is 30 square units. So, the side length is:
[tex]a=\sqrt{30}[/tex]
It is not exact. We know that [tex]\sqrt{25}<\sqrt{30}<\sqrt{36}[/tex].
Therefore, the side length is between 5 and 6.
