The solution is Option A.
The equation which has a constant of proportionality k = 7 is 4y = 28x
What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the equation be represented as A
Now , the value of A is
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
Now , the equation is
4y = 28x
On simplifying the equation , we get
Divide by 4 on both sides of the equation , we get
y = 28x/4
y = 7x
y = 7x is of the form y = kx where the value of k is 7
Therefore, the value of k is 7
Hence , the value of proportionality constant is 7

3.17, because there are about 1.056 quarts in one liter.
1.056 times 3 = 3.168, which, rounded to the nearest hundredth, is 3.17.
hope this help :)
After rounding off the obtained value, the value obtained in quarts will be equal to 3.17 qt.
What is rounding off values?The act of simplifying a number so that its value remains near to what it was is known as rounding. The outcome of rounding off a figure is less precise but simpler to utilize. They directly involve if a number's digits are taken into account while rounding it.
As per the given information in the question,
As we know,
1 liter = 1.057 quarts
Then, the number of quarts in 3 L will be equal to,
3 × 1.057
= 3.171 ≈ 3.17 qt

What is division?Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
given that,
Julie uses 4 green beads and 6 blue beads in each bracelet she makes.
Julie will use when she uses 24 blue beads
we have to find the total number of green beads Julie will use when she uses 24 blue beads
so, we have,
4 green beads and 6 blue beads in each bracelet
i.e. green beads : blue beads = 4 : 6
now. let, x green beads Julie will use when she uses 24 blue beads
i.e. green beads : blue beads = x: 24
we get,
4 : 6 = x: 24
so. x = 4 * 24 / 6
24 divided by 6= 4
4x4=16
we get,
For every 6 blue beads Julie used she used 4 green and she made 4 brackets so times 4x4 getting you to 16
Hence. 16 green beads Julie will use when she uses 24 blue beads.
