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

24b

Step-by-step explanation:

hmmm.

the other answer says the volume of a wedge is

4/9 × pi×r³

but I read here only

4/9 × pi³

so, what is correct ?

if I assume my reading is correct, then the solution is actually

4/9 × pi×r³ = 4/9 × pi³

pi×r³ = pi³

r³ = pi²

[tex]r = \sqrt[3]{ {\pi}^{2} } [/tex]

and that would mean

r ≈ 2.145

The formula for the perimeter of a rectangle is 2L+2W=P where W is the width and L is the length. This is because we have our two sides that are lengths and our two sides that are widths (different values) and we add them together to see what the distance around the whole rectangle is.

So, let's insert these values into the equation.

2(2x+4)+2(x+8)=96

We use the distributive property to remove the parentheses (which is us multiplying our equations for length and width by two).

4x+8+2x+16=96

We combine the like terms.

6x+24=96

We subtract 24 from both sides.

6x=72

Divide both sides by 6.

x=12

Now that we have our value of x, we can plug it into our length and width equations to find those values.

LENGTH:

2x+4

2(12)+4

24+4

28

WIDTH:

x+8

12+8

20

So, our length is 28 and our width is 20.

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)

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

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)

A.

[tex] \sqrt{x } \div 2[/tex]

is the answer

The choice which is equivalent to [tex]\sqrt{\frac{2}{x}}\cdot\sqrt{\frac{x^2}{8}}[/tex] is given by (A) [tex]\frac{\sqrt{x}}{2}[/tex].

Expression is a mathematical term that involves variables, numbers and other mathematical quantities and operations or combinations of them.

The given expression is [tex]\sqrt{\frac{2}{x}}\cdot\sqrt{\frac{x^2}{8}}[/tex]

Calculating the expression we get,

[tex]\sqrt{\frac{2}{x}}\cdot\sqrt{\frac{x^2}{8}}=\sqrt{\frac{2}{x}\cdot\frac{x^2}{8}}=\sqrt{\frac{x}{4}}=\frac{\sqrt{x}}{2}[/tex]

So the expression equals to [tex]\frac{\sqrt{x}}{2}[/tex].

Hence the correct option is (A).

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.
