One-third of x will also give one-third of y. The correct option is D.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that two quantities, x and y, are directly proportional. If x is directly proportional to y it means that x varies directly with y.
x ∝ y
If multiply the value of x by ( 1 / 3 ) the value of y will also be multiplied by ( 1 / 3 ).
Therefore, one-third of x will also give one-third of y. The correct option is D.

4. FH bisects ∠GFI, m∠EFG = 4y + 8 and m∠HFI = 2y + 6. Find m∠EFH.
please help me solve this
Answer:
m∠EFH=134
Step-by-step explanation:
FH bisects ∠GFI
So m<GFH=m<HFI
m∠EFG = 4y + 8 and m∠HFI = 2y + 6
m<GFH=2y+6
[tex]m<EFG+m<GF+m<HFI= 180[/tex] because its a linear pair
[tex]4y+8+2y+6+2y+6=180[/tex]
combine like terms and solve for y
[tex]8y+20=180[/tex]
Subtract 20 from both sides
[tex]8y=160[/tex]
Divide both sides by 8
y=20
m∠EFH=m<EFG+m<GFH
m∠EFH=[tex]4y+8+2y+6=6y+14=6(20)+14=134[/tex]

Of video game that originally cost $25.99 is on sale for 50% off if you have $14 would you have enough money to buy the video game explain (estimate)
Final answer:
After calculating 50% of $25.99, which is approximately $13, we find that the estimated sale price of the video game is $13. Therefore, if the student has $14, they will have enough money to buy the discounted video game.
Explanation:
The student is asking whether $14 would be enough to purchase a video game that is on a 50% off sale from its original price of $25.99. To find the sale price, we can take 50% of the original price and subtract it from the original price itself.
First, calculate 50% of $25.99: (0.50) imes $25.99 = $12.995. Since we are estimating, round the 50% value to $13. Now, subtract that from the original price to get the sale price: $25.99 - $13 = $12.99 (rounded to $13 for easier calculation).
In this estimate, the sale price is $13, which means that if the student has $14, they would have enough money to buy the video game on sale because $14 is greater than $13. Therefore, they will have $1 left after the purchase.

A drawing of a garden uses a scale of 1 in 3 ft. Find the length of the drawing is 13 inches
The length of the original drawing will be 39 feet.
Given scale:
1 inch = 3 feet
Length of the drawing = 13 inches
What is a scale factor?A scale factor is a factor by which the dimensions of an object are enlarged.
1 inch = 3 feet
So, 13 inches =13*3 feet
13 inches =39 feet
So, the length of the original drawing =39 feet.
Hence, the length of the original drawing will be 39 feet.

what is the function of delta sign in maths
Final answer:
The delta sign (Δ) in mathematics indicates a change in a certain quantity, calculated by subtracting the initial value from the final value, commonly used for indicating displacement in physics.
Explanation:
The delta sign (uppercase Greek letter delta, Δ) is commonly used in mathematics to denote a change in a certain quantity. When we say Δx, it signifies the 'change in x' or the difference between the final and initial values of 'x'. This is typically calculated by subtracting the initial value xo from the final value xf. For instance, if we're calculating displacement, which is a change in position, we subtract the starting position xo from the ending position xf to get Δx. The SI unit for displacement is the meter, but other units such as kilometers may also be used, requiring conversion to meters for consistency in calculations.

The function f(x) is graphed on the coordinate plane.
What is f(−2) ?
Enter your answer in the box.
f(−2)=
Answer:
The value of f(-2) is, -2
Step-by-step explanation:
The graph which is shown on the coordinate plane passes through the two points i.e, (2,0) and (0, -1).
First find the equation for this line:
Using Point-Slope form for the equation of line: [tex]y-y_{1}=m(x-x_{1})[/tex] ..[1]
where m is the slope given by ;
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
First find the slope:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{-1-0}{0-2}[/tex]
⇒ [tex]m=\frac{-1}{-2} =\frac{1}{2}[/tex]
Now, substitute the value of m=[tex]\frac{1}{2}[/tex] , [tex]x_{1}[/tex]= 2and [tex]y_{1}[/tex]=0 in equation [1];
[tex]y-0=(\frac{1}{2})(x-2)[/tex] or
[tex]y=\frac{1}{2}\cdot (x-2)[/tex]
In this graph x represents the input of the process and Y the output of the process and f the function of the variable x i.e, y=f(x)
∴ [tex]y=f(x)=\frac{1}{2}(x-2)[/tex] ....[2]
now, we put the value of x=-2 inequation [2] to solve for f(-2).
[tex]f(-2)=\frac{1}{2}(-2-2) =\frac{1}{2} \cdot (-4)[/tex]
Simplify we get;
[tex]f(-2)=-2[/tex]

There are 16 sixth graders and 20 seventh graders in the robotics club. For the first project the club sponsor wants to organize the club members into equal size groups. Each group will have only sixth graders or only seventh graders how may students will be in each group if each group has the greatest possible numbers of club members?
Answer:
There will be 4 students in each group and there will be 9 groups.
Step-by-step explanation:
There are 16 sixth graders and 20 seventh graders in the robotics club.
As we have to find the number of students that will be in each group if each group has the greatest possible numbers of club members, so we will find the HCF or highest common factor of 16 and 20.
16 = 2 x 2 x 2 x 2
20 = 2 x 2 x 5
HCF = 2 x 2 = 4
So, 16 sixth graders will be divided in [tex]\frac{16}{4}=4[/tex] groups
20 seventh graders will be in [tex]\frac{20}{4}=5[/tex] groups
total groups = [tex]4+5=9[/tex]
Hence, total there will be 9 groups with 4 students in each group.

1. Write the ratio in the simplest form. 16:24 (1 point) 1:2 4:3 3:4 2:3
Any ratio can be simplified into its simplest form by dividing the numerator and denominator by the common factor.
The given ratio is 16:24. To bring the ratio in its simplest form we will look for the factors of 16 and 24 and look for the greatest number that divides both 16 and 24.
The greatest number that divides both 16 and 24 is 8.
16÷8=2
24÷8=3.
The ratio 16:24 in its simplest form is 2:3
The solution for the ratio in the simplest form is, 2 : 3
Given that,
16:24 is the specified ratio.
Now, By finding the largest integer that divides both 16 and 24 and the factors of 16 and 24, we may reduce the ratio to its most basic form.
Hence, 8 splits both 16 and 24 to the maximum possible extent.
So, we get;
16 / 8 = 2
24 / 8 = 3
Thus, the simplest form of the fraction is,
⇒ 16 : 24
⇒ 16 / 24
⇒ 2 / 3
It can be written as,
⇒ 2 : 3
So, the simplest form is,
⇒ 2 : 3
