Step-by-step explanation:

Mr Lee has a family of 6 people and Mrs Scarlett has a family of 4. They were given 15 kg of chocolate
when they visited a chocolate factory for work. If they decide to share it so that each family
member gets an equal amount, determine the required ratio and hence calculate how much
chocolate Mr Lee and Mrs Scarlett will each take home to their families.

Answers

Answer:

Mr. Lee takes home 9 kg of chocolate.

Mrs. Scarlet takes home 6kg of chocolate.

Step-by-step explanation:

Mr. Lee has a family of 6 people, and Mrs. Scarlett has a family of 4 people.

Together, the total number of people is 6 + 4 = 10

If we divide evenly the chocolate between all 10, then each one gets the same amount.

Then we need to do the quotient:

15kg/10 = 1.5kg

This means that each person gets 1.5kg of chocolate.

And Mr. Lee has 6 on his family, then the amount of chocolate that Mr. Lee takes home is 6 times 1.5 kg

6*1.5kg = 9kg

Mr. Lee takes home 9 kg of chocolate.

Mrs. Scarlett has a family of 4 people, then she takes home 4 times 1.5kg of chocolate, this is:

4*1.5kg = 6kg

Mrs. Scarlet takes home 6kg of chocolate.

Answers

Answer:Rounding a decimal to the nearest whole number means to write down the whole number that the decimal number is closest to.

The decimal number of 1.3 is in between the whole numbers of 1 and 2.

1.5 is directly in between 1 and 2.

1.3 is closer to 1 than it is to 2 because it is on the left of 1.5.

MULTIPLE CHOICE 9th grade math: help me find the formula to the nth term:

Answers

Answer:

[tex]a_{n}[/tex] = - 5n - 2

Step-by-step explanation:

There is a common difference between consecutive terms, that is

- 12 - (- 7) = - 17 - (- 12) = - 5

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 7 and d = - 5, then

[tex]a_{n}[/tex] = - 7 - 5(n - 1) = - 7 - 5n + 5 = - 5n - 2

x = 12°

Detailed explanation down below.

Step-by-step explanation:

Ill be delighted to help

8° + 6x is an exterior angle. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.

In this situation, those two angles are 30° and 4x+2°

So lets put this in an equation

30° + 4x + 2° = 8° + 6x

4x + 32° = 6x + °8

Now lets subtract 8° from both sides to make it simpler

New equation =

4x + 24° = 6x

Lets evaluate X=

6x - 4x = 24°

2x = 24°

x= 24/2

x= 12°

what does the a in y=a(1+r)x represent?

Answers

Answer:

The function is of the form y = a(1 − r)t, where 1 − r < 1, so it represents exponential decay. Use the decay factor 1 − r to find the rate of decay. Write an equation. Solve for r.

The "a" in the expression y = a (1+r)ˣ represents the initial amount.

What is the expression?

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.

Given, a exponential expression  y = a (1+r)ˣ

The exponential growth can alternatively be calculated using the formula f(x) = a(1 + r)ˣ, where the function is denoted by the f(x) term. The initial value of your data is represented by the variable. The growth rate is represented by the r variable.

Therefore, the initial amount is been represented by "a" in the given expression.
