can someone please help me ?

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:

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

A 1000 times smaller

Step-by-step explanation:

whatever power it is to 10 is how many zero's so since it's -3 it goes back 3 zero's  

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]

are NOT power functions.

Answer:  -2x + 5y = 8

Step-by-step explanation:

Since the lines must be parallel, the slopes must be the same, so keep the coefficients of x and y

Substitute the values of x and y from the given coordinate  (6,4) to find the new constant, b, the y-intercept.

-2x + 5y = b

-2(6) + 5(4) = b

-12 + 20 = b

8 = b

Rewrite the original equation substituting the new b for the original -15

-2x + 5y = 8

Answer:

Step-by-step explanation:

Slope - intercept form

Given line

Converting the equation into slope-intercept form

Parallel lines have same slope of 2/5

Using point (6, 4) lets find it's y-intercept (b)

So the line is

Step-by-step explanation:

Answer:

$1670.22

Step-by-step explanation:

In order to solve this probelm we must first calculate the total amount that you  have to pay the bank which would be the amount you borrowed times the interest rate 12.6% or 0.126 (but add the one to add it to the amount borrowed) in decimal ...

$3450 * 1.126 = $3884.70

Now we have to find how much you have already paid by multiplying the amount per month by the amount of months you have paid, since you have been paying for 2 years that means it has been 24 months

92.27 * 24 = $2214.48

Finally we subtract the amount you paid from the total owed to find out how much you still owe

3884.70 - 2214.48 = $1670.22

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:

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:

exact area = 25(pi) m^2

approximate area = 78.54 m^2

Step-by-step explanation:

diameter = 10 m

radius = diameter/2 = 10 m / 2 = 5 m

area = (pi)r^2

area = (pi)(5 m)^2

area = 25(pi) m^2

area = 78.54 m^2

I got this question right on my assessment.

Answer:

chances of that would be a 5%

Answer:

100 probably

Step-by-step explanation:

Becuase it was bisected and bisect me as to divide in to two.. So when u get 50 deg.. The total is 100

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:

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: The entered points belong to a vertical line. There is no slope.

Equation: x = -3.

This is what i think..

The slope is the ratio of the rise to the run of a line. It is also called the rate of change or gradient. Therefore, the slope of the line is 0

Slope = Rise / Run

Rise = y2 - y1 = (13 - 3) = 10

Run = x2 - x1 = (-3 - (-3)) = (-3 + 3) = 0

Slope = Rise / Run = 10 / 0 = 0

Therefore, the slope of the line is 0
