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.

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.

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

∵ 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]

Answer: 40 . 2 and 40 + 40

Step-by-step explanation:

The expression which shows the saving is 40 + 40 and 40 x 2. The correct options are C and D.

The mathematical expression combines 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 the amount of money saved by Erica is $40. The expression which represents the savings will be,

40 + 40 = 80

40 x 2 = 80

Therefore, the expression which shows the saving is 40 + 40 and 40 x 2. The correct options are C and D.

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

Answer:

D. 4^4 x 4^-7

Step-by-step explanation:

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

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
