Answer:

3 and 18

Step-by-step explanation:

let x be the first number

let 6x be the second number

x + 6x = 21

7x=21

x=21/7

x=3

second number =6x

second number 6x3= 21

Answer:c

Step-by-step explanation:

This is how it should be when you are representing an exponential equation to a logarithmic equation

[tex]y=a^{x}[/tex]→log y base a =x

therefore the answer is c

The exponential equation which rewrites the logarithmic equation is given by 6ˣ = 18

The power to which a number must be increased in order to obtain another number is known as the logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm

The properties of Logarithm are :

log A + log B = log AB

log A − log B = log A/B

log Aⁿ = n log A

Given data ,

Let the logarithmic equation be represented as A

Now , the value of A is

log₆ 18 = x

From the properties of logarithm , we get

log Aⁿ = n log A

On simplifying , we get

6ˣ = 18

where the value of x = 1.61314

Hence , the exponential equation is 6ˣ = 18

Answer:

66.6% (see below)

Step-by-step explanation:

Each sphere 4/3[tex]\pi[/tex]r²=4/3[tex]\pi[/tex](4²)=268.08cm³

Assuming the tube is the same width and height as the three spheres,

V=[tex]\pi[/tex]r²h=[tex]\pi[/tex](4²)24=1206.37

The three spheres are 268.08*3=804.24cm³

The tube is 1206.37cm³

I’m not sure if your question is asking the percentage of the tube that’s filled, or the percentage that’s unfilled.

Filled: 804.24÷1206.37=0.66666=66.6%

Unfilled: 1206.37-804.24=402.13

402.13÷106.37=0.33333=33.3%

Answer:

Percentage of Tube Unfilled : 33 and 1/3%

Step-by-step explanation:

It's most likely that we want to calculate the percentage of the tube unfilled, as the tube itself wouldn't be provided otherwise. We can start by calculating the volume of the tube --- (1)

The volume of a cylinder is represented by πr²h. Substituting we would receive π(4)²h. h is represented by 3 times the diameter of each sphere, as it is aligned such. Diameter = 2 * r = 2 * 4 = 8, so h = 3 * 8 = 24. Therefore Tube Volume = π(4)²(24) = π(16)(24) = 384π.

Now let's solve for the volume of a sphere, multiplying by three to receive the total volume of all 3 spheres --- (2)

Volume of 1 Sphere : 4 / 3πr³ = 4 / 3π(4)³ = 4 / 3π * 64 = 256 / 3π

Volume of all 3 Spheres : 256 / 3π * 3 = 256π

And now the volume of the tube that is unfilled, will be 384π - 256π = 128π. The total volume of the tube is 384π, so the percentage of the unfilled tube will be 128π / 384π or 128 / 384 = 0.333333333 * 100 = 33.33333...%. Therefore the percentage of the tube that is not filled will be 33.33% approximately, or 33 and 1/3% in exact terms.

Step-by-step explanation:

Hey, there!!

Let me explain you very simply, ok.

Here, according to the question,

[tex]{x}^{2} = \frac{25}{144} [/tex]

X is square so, which finding the value of x you must take it to the right side (in root form ). so,

[tex]x = \sqrt{ \frac{25}{144} } [/tex]

Now, as we know that,

sq.root of 25 = 5

sq.root of 144 = 12

Now, you write it as,

[tex]x = \sqrt{ \frac{ {5}^{2} }{ {12}^{2} } } [/tex]

[tex]or \: x = \sqrt{( { \frac{5}{12} )}^{2} } [/tex]

Now, square root and (5/12) square ( square root , square gets cancelled).

You will get as,

[tex]x = \frac{5}{12} [/tex]

And its your simplified answer.

920/100x110/92

After this you will get 11 dollars.

That is the amount to send 110 text messages.

The cost to send 110 text messages is $11.

Given that, it cost Paisley $9.20 to send 92 text messages.

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Let the cost to send 110 text messages be x.

Now, 9.20:92::x:110

⇒ 9.20×110=92×x

⇒ 92x=1012

⇒ x=1012/92

⇒ x=$11

Hence, the cost to send 110 text messages is $11.

Answer: 14

Step-by-step explanation:

Given the sequence : 55 176 539 1628

Each number after the first is derived by multiplying by x and then adding y;

If x and y are > 0 and they are integers.

Taking 55 and 176:

176 = 55*x + y

539 = 176*x + y

55x + y = 176 - - - (1)

176x + y = 539 - - (2)

From (1) y = 176 - 55x

Substitute y = 176 - 55x into (2)

176x + 176 - 55x = 539

121x = 539 - 176

121x = 363

x = 363 / 121

x = 3

Put x = 3 in y = 176 - 55x

y = 176 - 55(3)

y = 176 - 165

y = 11

x = 3, y = 11

x + y = 3 + 11 = 14

Tallness of the apple tree = x

Tallness of the elm tree= 3 1/2x

Apple tree = 10 2/3 feet tall

Elm tree = 3 1/2x

Where x= 10 2/3

Elm = 3 1/2 (10 2/3)

[tex]x = \frac{w}{(u + r)} [/tex]

Step-by-step explanation:

ux + rx = w

x(u + r) = w

x = w/(u + r)

the dash '/' represents fraction

The required solution is x = w/(u + r).

It is required to find the value of x.

A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.

Given:

The given equation is

u x + r x = w

Taking common x  we get,

x(u + r) = w

Divide (u + r)  on both sides we get,

x = w/(u + r)

Therefore, the required solution is x = w/(u + r).

The expression that shows the total number of songs on Iris playlist is 120 + 4w

A linear expression is an expression that has only one variable. The single variable is raised to the power of 1.  An example of a linear expression is x + 10  

Iris already has 120 songs on her playlist. She increases her playlist every week by four songs.

This means that each week, her playlist increases by 4. This can be represented with the expression : 4 x w = 4w

Where w represents the number of weeks.

In week 10, her playlist increases by: 4 x 1 = 4 songs

In week 10, her playlist increases by : 4 x 10 = 40 songs

But Iris already has 120 songs

This can be represented with the expression 120 + 4w

After 1 week, the total songs she would have is 120 + 4 = 124 songs

After 10 weeks, the total songs she would have is 120 + 40 = 160 songs
