Answer:

x= (k - c) / 6

Step-by-step explanation:

6x + c = k

6x = k - c

x = (k - c) / 6

Answer:  [tex]x=\frac{k}{6} - \frac{c}{6}[/tex]

Step-by-step explanation:

6x + c = k    To solve for x first subtract c from both sides

    -c      -c

6x =k - c       Now divide both side by 6.

x=  k/6 - c/6

Answer:

$22

Step-by-step explanation:

So if a videotape was on a 40% discount, then the person who is buying it pays 60% of the original price (100 - 40 = 60)

call "x" the original price, then set up a proportion to explain the relationship

13.2/x = 60/100

simplify

13.2/x = 3/5

solve using cross products

13.2/x = 3/5

13.2 * 5 = 3 * x

66 = 3x

22=x

Answer:

chances of that would be a 5%

First quartile of the distribution is, Q = 39.

i.e 75% of students have scored more than 39.

So, total number of students scored more than 39 are :

[tex]n=\dfrac{416\times 75}{100}\\\\n=312[/tex]

Therefore, number of students scored higher than 39 are 312.

Hence, this is the required solution.

Answer:

A. equilateral triangle

B. square

D. regular hexagon

E. regular octagon

G. regular dodecagon

Step-by-step explanation:

The regular polygons could be used to make regular and semi-regular tessellations are equilateral triangle, square and regular hexagon. Therefore, the correct answers are A, B and D.

A regular tessellation is tessellation made up by using only one type of regular polygon. These are made up of completely congruent regular polygons all that connecting vertex to vertex.

Regular polygons have congruent straight sides. When we slide or rotate a regular polygon, the side of the original figure and the side of its translation will match.

Equilateral triangles, squares and regular hexagons are the only regular polygons that tessellate. Therefore, there are only three regular tessellations.

Therefore, the correct answers are A, B and D.

Answer:

p=£154,500

T=2years

R=4%

Compound Amount (CA) =?

Now,

CA=p(100+R/100)^T

=154500*(100+4/100)^2

=154500*(104/100)^2

=154500*(1.04)^2

=154500*1.0861

=167107.2

Therefore The value of the investment will be £167107.2 after 2year

The value of the investment at the end of 2 years is £167107.2.

Given that, principal =£154500, time period= 2 years and rate of interest =4%.

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

The formula used to find the compound interest = [tex]Amount=P(1+\frac{R}{100} )^{nt}[/tex]

Here, Amount = 154500(1+4/100)²

= 154500(1+0.04)²

= 154500(1.04)²

= 154500×1.0816

= £167107.2

Hence, the value of the investment at the end of 2 years is £167107.2.

Answer:

The numerical length of RS is 22 units

Step-by-step explanation:

∵ Point S is on the line segment RT

→ That means S divide RT into two parts RS and ST

∴ RS + ST = RT

∵ RS = 4x - 10

∵ ST = 2x - 10

∵ RT = 4x - 4

→ Substitute them in the statement above

∴ 4x - 10 + 2x - 10 = 4x - 4

→ Add the like terms in the left side

∴ (4x + 2x) + (-10 + -10) = 4x - 4

∴ 6x + (-20) = 4x - 4

∴ 6x - 20 = 4x - 4

→ Add 20 to both sides

∴ 6x -20 + 20 = 4x - 4 + 20

∴ 6x = 4x + 16

→ Subtract 4x from both sides

∴ 6x - 4x = 4x - 4x + 16

∴ 2x = 16

→ Divide both sides by 2 to find x

∴ [tex]\frac{2x}{2}=\frac{16}{2}[/tex]

∴ x = 8

→ Substitute the value of x in Rs to find its length

∵ RS = 4(8) - 10

∴ RS = 32 - 10

∴ RS = 22 units

The numerical length of RS is 22 units

Answer:

x<9

Step-by-step explanation:

Answer:

x < 9

Step-by-step explanation:

Step 1: Write inequality

x - 6 < 3

Step 2: Add 6 to both sides

x < 9

Here, we can see any x value that is smaller than 9 will work. So x can be 5, 2, 0, or even -1597239065723.

Answer: 49

Step-by-step explanation:

From your question, I think you mean the largest number. The answer is given below.

Let the five consecutive odd numbers be:

a, a+2, a+4, a+6 and a+8.

Thee sum of the first and double the last is 139. This can be written as:

a + 2(a+8) = 139

a + 2a + 16 = 139

3a + 16 = 139

3a = 139 - 16

3a = 123

a = 123/3

a = 41

The first number = 41

The largest number = a+8 = 41 + 8 = 49.

Answer:

Se requiere 30 botes de 0.25 litros para dos galones de pintura.

Step-by-step explanation:

Sabemos que un galón equivale a 3.7354 litros, para estimar en cuantos botes de 0.25 litros se puede distribuir dos galones, empleamos la siguiente expresión:

[tex]n = \frac{V_{total}}{V_{bote}}[/tex]

Donde:

[tex]V_{bote}[/tex] - Volumen del bote, expresado en litros.

[tex]V_{total}[/tex] - Volumen total, expresado en litros.

[tex]n[/tex] - Cantidad de botes a llenar, adimensional.

Si sabemos que [tex]V_{bote} = 0.25\,L[/tex] y [tex]V_{total} = 2\,gal[/tex], entonces:

[tex]n = \frac{(2\,gal)\cdot \left(3.7354\,\frac{L}{gal} \right)}{0.25\,L}[/tex]

[tex]n = 29.883[/tex]

Puesto que la cantidad de botes es representada por un número entero,la cantidad requerida se redondea por exceso al entero más cercano. En consecuencia, se requiere 30 botes de 0.25 litros para dos galones de pintura.

Answer and Step-by-step explanation: Power Functions are of the form:

[tex]f(x)=ax^{b}[/tex]

where a is scaling factor, which means, it moves the values of [tex]x^{b}[/tex] up or down;

and b is exponent or power, which determines the rate of growth or decay of the function.

The difference between exponential and power functions, is that in power functions, a variable base is elevated to a fixed exponent.

For that reason, Equations:

A. [tex]f(x)=2^{4\sqrt{x} }[/tex]

B. [tex]f(x)=\frac{\pi}{x}[/tex]

C. [tex]f(x)=2.3^{x}[/tex]

D. [tex]f(x)=2^{3\sqrt{x} }[/tex]

Answer:

$112

Step-by-step explanation:

To find the amount he got paid, subtract the current amount from the initial amount

so

287 - 175

= 112

Hey there!☺

[tex]Answer:\boxed{\$112}[/tex]

[tex]Explanation:[/tex]

Sanjai had $175 in his bank account before he got paid this week. And now his total is $287. Represent x as how many he got after he paid. So that means you do $175 + x = $287.

[tex]175+x=287[/tex]

We have to find x and see how much money he got paid to get 287 in his balance.

[tex]287-175=112[/tex]

x is equal to 112. Let's see if $112 makes x true.

[tex]175+112=287[/tex]

That makes x true which means he got paid $112.

Hope this helps!☺
