k=2
k = 2/3
k = 3/2
k= 3

Answers

Answer:

The constant of proportionality is k = [tex]\frac{2}{3}[/tex] ⇒ B

Step-by-step explanation:

The form of the equation of the proportionality is y = k x, where

k is the constant of proportionality

∵ Marjorie made 4 wreaths in 6 hours

→ Let y the number of wreath and x is the time of making them

y = k x

y = 4 and x = 6

→ Substitute them in the equation

4 = k(6)

∴ 4 = 6k

→ Divide both sides by 6 to find k

∵ [tex]\frac{4}{6}[/tex] = [tex]\frac{6k}{6}[/tex]

[tex]\frac{2}{3}[/tex] = k

Let us use the other information to be sure it will give us the same value of k

∵ She made 6 wreaths in 9 hours

y = 6 and x = 9

→ Substitute them in the equation

6 = k(9)

∴ 6 = 9k

→ Divide both sides by 9 to find k

∵ [tex]\frac{6}{9}[/tex] = [tex]\frac{9k}{9}[/tex]

[tex]\frac{2}{3}[/tex] = k

The constant of proportionality is k = [tex]\frac{2}{3}[/tex]

Option D is correct,  4⁴×4⁻⁷ is equivalent to the expression 1/64

What is Expression?

An expression is combination of variables, numbers and operators.

The given expression is 1/64

One divided by sixty four

We need to find the expression which is equivalent to One divided by sixty four.

We know that 4×4×4 is 64

Which means 4³=64

4⁴×4⁻⁷ = 4⁻³

1/64 = 1/4³

= 4⁻³

So 4⁴×4⁻⁷  is equal to 1/64

Hence, Option D is correct,  4⁴×4⁻⁷ is equivalent to the expression 1/64

Step-by-step explanation:

work out a & e

Answers

Answer:

a = 14

b = 15

c = 15

d = 18

e = 18

Step-by-step explanation:

The stratified sampling works as follows:

stratified sampling = (Population of subgroups)*(total sample size)/(entire population)

in this case, sample size = 80

entire population = 140 + 150 + 150 + 180 + 180 = 800

Population sample is the number of students of each year (for year 7, the population of subgroup is 140, and so on)

whith this equation we can find all the missing values:

a = (140)*(80/800) = 14

b = (150)*(80/800) = 15

c = (150)*(80/800) = 15

d = (180)*(80/800) = 18

e = (180)*(80/800) = 18

Simplify: 4(36)?????

Answers

Answer:

To reduce this fraction, simply divide the numerator and denominator by 4 (the GCF). So, 436 = 4÷436÷4 = 19. Thus, 436 is equivalent to 19 in the reduced form.

Step-by-step explanation:

The solution for the expression 4(36) after you simplify can be expressed as 144.

What is 4(36) when you simplify?

To simplify the expression 4(36), we need to perform the multiplication operation.

4 multiplied by 36 can be calculated as follows:

4 x 6 = 24 (multiplying the units digit)

4 x 30 = 120 (multiplying the tens digit)

Now, we add the results together:

24 + 120 = 144

Therefore, the number 4 multiplied by the number 36in brackets is equals to 144.
