Answer:

Rule is 4(5)^(n-1).

a7 = 62500.

Step-by-step explanation:

This is a geometric sequence with a1 = 4 and r = 20/4 = 5.

a7 is 4(5)^(7-1)

= 4 * 5^6

= 62500.

the general form of the given sequence is a(n) = 4 * 5ⁿ⁻¹ and a(7) is 62500.

A geometric sequence is a sequence of numbers that follows a pattern where the next term is found by multiplying by a constant called the common ratio, r.

Given a sequence  4, 20, 100, 500, ...

From the general formula of the nth term of the geometric sequence:

a(n) = arⁿ⁻¹

where,

a is the first term

r = ratio of two subsequent terms

in our case

a = 4

r = 20/4 = 5

thus, the general form of the given sequence

a(n) = 4 * 5ⁿ⁻¹

To find: a(7)

a(7) = 4 * 5⁶

a(7) = 62500

therefore, the general form of the given sequence is a(n) = 4 * 5ⁿ⁻¹ and a(7) is 62500.

Answer:

Chim is 34 years old, and Jared is 8 years old.

Step-by-step explanation:

Let c be Chim's age and j be Jared's age.

Chim's age after five years (c + 5)

is 3 times Jared's age after five years (3 * (j+5) )

#1: c + 5 = 3(j+5)

We can add Chim's age and Jared's age to get 42 (the "sum"):

#2: c + j = 42

This is a system of equations that we can solve through substitution:

c + 5 = 3(j+5)

c + j = 42

In Equation #2, we can subtract j from both sides:

c = 42 - j

Then replace c with 42 - j in the first equation

(42 - j) + 5 = 3(j+5)

47 - j = 3j + 15

32 = 4j

j = 32/4 = 8

Plug j = 8 into the second equation, then solve for c.

c + 8 = 42

c = 42 - 8 = 34

c = 34, j = 8

Check our work by plugging in c = 34 and j = 8 into the first equation:

34 + 5 = 3(8+5)

39 = 3*13

39 = 39

Plug c and j into the second equation:

34 + 8 = 42

42 = 42

Chim is 34 years old, Jared is 8 years old.

Answer:

A. mB = 40°

Step-by-step explanation:

In geometry, congruent figures are identical in form, coinciding exactly when superimposed.

From the diagram,

<CAB = 80°; <EFG = 40° and <FGE = 60°

From triangle ️ EFG,

<GEF + <EFG + <FGE = 180°

》<GEF = 180° - (<EFG + <FGE)

<GEF = 180° - (40° + 60°)

<GEF = 180° - 100°

<GEF = 80°

》<GEF = <CAB = 80°

Also,

》<ACB = <EGF = 60°

<ABC = <EFG = 40°

NB. <ABC = mB

Real numbers may be explained as all set of numbers which may be used for counting, fractions or decimals. Real numbers may be any set of natural, whole, integer, rational or irrational numbers.

• NATURAL NUMBERS which are all set of positive whole numbers from 1. Examples : (1, 3, 5, 8, 100)

• WHOLE NUMBER are set of all natural numbers .while numbers also include the value value (0, 1, 200, 500) are whole numbers

• INTEGERS : include all positive and negative natural or whole number values. They include (-1, - 10, 10, 5)

• RATIONAL numbers are real numbers which can be expressed in the form m/n where both m and n are integer values and the denominator, n ≠ 0 Examples : (1/2, 0.9, 10/1, √4, 3.5)

• IRRATIONAL numbers are real numbers which are not integer values and cannot be expressed in the form m/n Non-terminating and non-repeating decimal numbers are IRRATIONAL numbers. (√3, 1.43136..., 1.4141..., π)

Hi! I'm happy to help!

To solve this, we need to first find how much the car value decreased.

The car started at $32,000, but dropped down to $6,300. To find the value drop, we use subtraction.

$32,000-$6300

$25,700

Now we know that his car value dropped $25,700 in value over the course of 3 years. Now we need to figure out how much value it dropped per year. To do this, we split the money into 3 years.

$25,700÷3

$8,566.6666666...

We can round this to $8,567

On average, his car lost $8,567 in value, per year. Now, we need to find how much value his car had after one year in order to get our integer. (a fraction of 2 whole numbers)

$32,000-$8,567

$23,433

Now that we know what his can was worth after one year, we can say that his can was worth $23,433 out of the $32,000 originally was worth. Out of can mean division, or fraction, and because these are both whole numbers, and integer. This is our integer:

[tex]\frac{23433}{32000}[/tex]

Since we cannot simplify it, this is our integer that represents the average decrease in value per year.

Answer:

5w³

Step-by-step explanation:

To solve this, we can list the factors of each number and see which are common

25w⁵: separate this into 25 and w⁵ as one is a variable and one is not, so this will enable easier factorization. It is perfectly fine to separate these as these are multiplied by each other. For example, 5 is a factor of 25 but not of w⁵, but we can still factor 5 from 25w⁵ to get 5 (5w⁵)

factors of 25:

1, 5, 25

factors of w⁵:

1, w, w², w³, w⁴, w⁵

We know the factors of w⁵ because anything multiplied by 1 is equal to itself, w * w⁴ = w⁵, and w²*w³ = w⁵ due to exponent rules

Next,

factors of 5:

1, 5

factors of w⁴:

1, w, w², w³, w⁴

Finally,

factors of 15:

1, 3, 5, 15

factors of w³:

1, w, w², w³

For the constants, the greatest common factor is 5, and for the variables, the greatest common factor is w³

Because each value has both a constant and variable, we can use these two numbers to factor this out as

5w³(5w²+w + 3)

Step-by-step explanation:

Answer:

The answer is Jessica reads 24b books in 2 years where b is the number of books she reads each month.

Step-by-step explanation:

First, decide on your variable. You don't know how many books Jessica reads each month, but you know every month it is the same.

Let b equal the number of books Jessica reads each month.

Next, write a variable expression using b. In one month Jessica reads b books. In 2 months Jessica reads 2b books. The question asks for an expression that represents the total number of books Jessica reads in 2 years. There are 12 months in a year so there are 24 months in 2 years. So your expression is
