The value of the expression 6 (d - f) + f when d = 4 7/8 and f = 3 1/2 is 47/4 or [tex]11\frac{3}{4}[/tex] .
How to Solve Algebra expression?6 (d - f) + f
when d = 4 7/8 and f = 3 1/2
Given the data in the question;
d = 4 7/8 = f = 3 1/2 = What is 6 (d - f) + f = ?First, we convert the mixed fraction into an improper fraction
d = 4 7/8 = ( 8×4 + 7 )/8 = 39/8
f = 3 1/2 = ( 2×3 + 1 )/8 = 7/2
Now, we substitute the values of d and f into the expression.
234/8 - 42/2 + 7/2
234/8 - 168/8 + 7/2
33/4 + 7/2
33/4 + 14/4
47/4 or [tex]11\frac{3}{4}[/tex]
Therefore, the value of the expression 6 (d - f) + f when d = 4 7/8 and f = 3 1/2 is 47/4 or [tex]11\frac{3}{4}[/tex] .

Answers
The surface area and the volume of the cone is 816.4 km² and 7536 km³ respectively.
What is volume?Volume is the capacity of an object.
To calculate the surface area and volume of the cone shown above, we use equation 1 and equation 2 respectively.
Formula:
S = πr√(r²+h²)............. Equation 1V = πr²h.................. Equation 2Where:
S = Surface area of the coneV = Volume of the coner = Radius of the base of thye coneh = Vertical height of the cone.From the diagram,
Given:
r = 10 kmh = 24 kmπ = 3.14Substitute these values into equation 1 and equation 2 respectively.
S = 3.14×10[√(24²+10²)S = 31.4(√676)S = 31.4×26S = 816.4 km²Also for the volume of tyhe cone

Answers
Answer:
Lucas has 16 chocolate bars
Step-by-step explanation:
Let x = number of chocolate bars Lucas has
⇒ x - 2 = number of chocolate bars Caidon has
If they have 30 chocolate bars altogether then:
⇒ x + x - 2 = 30
⇒ 2x - 2 = 30
⇒ 2x = 32
⇒ x = 16
Therefore, Lucas has 16 chocolate bars (and Caidon has 14 chocolate bars).

if each polygon has 12 sides and each side length was 20 cm what is the area
Answers
Answer: approximately 4478.46096908264 square cm.
==========================================================
Explanation:
I'm assuming this is a regular 12-sided polygon
The area formula for regular polygons is
[tex]A = 0.25n*s^2*\cot(180/n)[/tex]
where in this case we have n = 12 sides and each side is of length s = 20
So,
[tex]A = 0.25n*s^2*\cot(180/n)\\\\A = 0.25*12*(20)^2*\cot(180/12)\\\\A = 0.25*12*(20)^2*\cot(15)\\\\A = 0.25*12*(20)^2*\frac{1}{\tan(15)}\\\\A \approx 4478.46096908264\\\\[/tex]
The area of this regular polygon is approximately 4478.46096908264 square cm.
Make sure your calculator is in degree mode when computing that value of cot(15) or 1/tan(15).
Area is measured in square units. This means that if we divide the shape into squares that are equal in size and count them up, the area is the total number of squares. Square units are always one unit of length long and one unit of length wide. In the song, the unit of length we use is feet. So each square unit is one foot long and one foot wide, or one square foot. Since there are 72 of these units in total, we say the area is 72 square feet. Square units can use other units of length, like inches or miles. Make sure you know what unit of length you’re using.

Maths problem in simultaneous equations

Answer:
Question 6: The cost of a chocolate bar is $1.20 and the cost of a box of gum is $0.75
Question 7: There were 7 students
Step-by-step explanation:
Question 6:We will be using system of equations which a set of one or more equations involving a number of variables. The solutions to systems of equations are the variable mappings such that all component equations intersect.
Our Variables:
- chocolate bar which will be represent as b in the equation
- box of gum which will be represent as g in the equation
Forming the equations:
Sally -
bought 2 chocolate bars (b)
bought 1 box of gum (g)
to a total of $3.15
so 2b + 1g = $3.15
Evans -
bought 1 chocolate bars (b)
bought 2 box of gum (1)
to a total of $2.70
so 1b + 2g = $2.70
Solving using substation:
2b + 1g = $3.15 we want to isolate b to input into the other equation
1b + 2g = $2.70
2b + 1g = $3.15 subtract 1g from both sides, divided both sides by 2
2b / 2 + 1g - 1g = $3.15 - 1g / 2
b = $3.15 - 1g / 2
Now substation b into the second equation
1b + 2g = $2.70 becomes 1($3.15 - 1g / 2) + 2g = $2.70
simplify,
$3.15 + 3g / 2 = $2.70 isolate g
$3.15 + 3g / 2 x 2 = $2.70 x 2 multiply both sides by 2
$3.15 + 3g = $5.40 subtract $3.15, divided by 3 from both sides
$3.15 - $3.15 + 3g / 3 = $5.40 - $3.15 / 3
g = $5.40 - $3.15 / 3
g = $2.25 / 3
g = $0.75
Now plug in g to get b into any equation:
If Sally equation is used
2b + 1g = $3.15
2b + 1(0.75) = $3.15 → 2b + 0.75 = $3.15
2b + 0.75 - 0.75 = $3.15 - 0.75
2b = $2.40 → 2b / 2 = $2.40 / 2
b = $1.20
If Evans equation is used
1b + 2g = $2.70
1b + 2(0.75) = $2.70 → 1b + 1.50 = $2.70
1b + 1.50 - 1.50 = $2.70 - 1.50
1b / 1 = $1.20 / 1
b = $1.20
Question 7:
Our Variables:
- adult which will be represent as A in the equation
- student which will be represent as S in the equation
Forming the equations:
- sample size: group of 30
- Adult cost $5 (A)
- Student cost $2 (S)
- Five members are free
to a total cost is $104
so A + S = 30 - 5
this is how many of each variable from the total group and we subtract 5 as 5 members were free
so 5A + 2S = $104
Solving using substation:
A + S = 25 we want to isolate a to input into the other equation
5A + 2S = $104
a = 18
s =7
