Bred has a total of 771 ways to paint the wall, taking into account that he can use at most two colors for the stripes or just one.

The subject matter pertains to the field of combinatorics, a branch of mathematics dealing with combinations and permutations. The task requires finding the number of ways to paint 8 stripes on a wall using up to 2 colors from a selection of 3 colors, namely: blue, red, and white. Since we have more paint than stripes, the limiting factor in this problem is the number of stripes, not the quantity of paint.

As Bred can use at most two colors for the stripes, the combinations we can have with two colors are: blue and red, blue and white, red and white. In each of these combinations, there are 2^8 (or 256) ways to paint 8 stripes (exploration of all binary possibilities). So, for three combinations, it will be 3*256 = 768 ways.

Now, let's look at the single color options. He can also paint the stripes all in one color, but since he has only three colors, he has three ways for this.

Hence, in total, Bred has 768 (from two-color combinations) + 3 (from single color option) = 771 ways to paint a wall.

The unit rate in the equation 64t = 384 is 64.

The unit rate in the equation 64t = 384 is 64.

To find the unit rate, we divide the total value by the number of units. In this case, the total value is 384 and the number of units is 64. When we divide 384 by 64, we get the unit rate of 6.

Therefore, the unit rate in the equation is 64.

Answer:

[tex]\large\boxed{b)\ y=\dfrac{3}{4}x-1}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b = y-intercpt → (0, b)

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (4, 2) and (0, -1) - y-intercept → b = -1.

(we see this already which equation. Only in b) y-intercept is b = -1).

Anyway, calculate the slope:

[tex]m=\dfrac{-1-2}{0-4}=\dfrac{-3}{-4}=\dfrac{3}{4}[/tex]

Finally we have the equation:

[tex]y=\dfrac{3}{4}x-1[/tex]

Answer:

Divide each side by -4

3/-4 g = -4x/-4

-3/4 g =x

The slope of the line is [tex]\frac{13}{6}[/tex].

A slope of a line is the change in y coordinate with respect to the change in x coordinate.

If [tex]P(x_{1} ,y_{1} )[/tex] and [tex]Q(x_{2} ,y_{2} )[/tex] are the two points on a straight line, then the slope formula is given by:

Slope, m = Change in y-coordinates/Change in x-coordinates

[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

According to the given question.

We have a two points (1, 6) and (-5,-7).

Therefore, the slope of the line from these points is given by

[tex]slope = \frac{-7-6}{-5-1} = \frac{-13}{-6} =\frac{13}{6}[/tex]

Hence, the slope of the line is [tex]\frac{13}{6}[/tex].

The Answer is hundredths

this is the answer to your equation

The solutions to the equation x² = -63 in simplified, rationalized form are:

x = 3√7 * i

x = -3√7 * i

Isolate x²: In this case, x² is already isolated on one side of the equation.

Apply the Square Root Property: Take the square root of both sides of the equation to eliminate the exponent on x²:

√(x²) = √(-63)

Simplify and Introduce Imaginary Unit: Recall that the square root of a negative number is an imaginary number. We introduce the imaginary unit 'i,' defined as √(-1):

x = ±√(63) * √(-1)

x = ±√63 * i

Simplify and Rationalize: √63 cannot be simplified further, but we can rationalize it by multiplying both the numerator and denominator by √3:

x = ±√63 * i * √3 / √3

x = ±3√7 * i

Answer:

3 times 10

Step-by-step explanation:

first off, let's solve the "given" line for "y", that way we can put it in slope-intercept form to see what its slope might be.

[tex]\bf 10x+2y=-2\implies 2y=-10x-2\implies y=\cfrac{-10x-2}{2} \\\\\\ y=\cfrac{-10x}{2}-\cfrac{2}{2}\implies y=\stackrel{\stackrel{m}{\downarrow }}{-5}x-1\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

well, a parallel line to that one, will have the same exact slope, so then, we're really looking for the equation of a line whose slope is -5 and runs through (0 , 12)

[tex]\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{12})~\hspace{10em} slope = m\implies -5 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-12=-5(x-0) \\\\\\ y-12=-5x\implies y=-5x+12[/tex]

False, .0034 is 1/10 of .034

The statement that 0.034 is 1/10 of 0.0034 is incorrect. In fact, 0.034 is 10 times larger than 0.0034. Thus, it's correct to say 0.0034 is 1/10 of 0.034.

No, the statement that 0.034 is 1/10 of 0.0034 is not correct. When comparing the two numbers, we can see that 0.034 is actually 10 times larger than 0.0034, not 1/10. To confirm this, we can perform the division operation: 0.034 ÷ 0.0034 = 10. Therefore, we can say that 0.0034 is 1/10 of 0.034, but not the other way around.

Answer:

35 ft²

Step-by-step explanation:

We set up a system of linear equations describing this rug and then solve it:

Perimeter:  P = 2L + 2W

L = (1  2/5)W = 1.4W

Going back to the Perimeter equation, and knowing that P here is 24 ft, we have:

24 ft = 2(1.4W) + 2W, or 2.8W + 2W, or 4.8W.

Solve for W (width) by dividing both sides of this equation by 4.8:

W = 24 ft  / 4.8  = 5

The width of the rug is 5 ft; the length is 1.4(5 ft), or 7 ft.

Thus the area of the rug is A = L * W, or A = (7 ft)(5 ft) = 35 ft²

The total cost of the regular price for a group of x people is represented by the equation C = 22x, while the total cost of the group special is represented by C = 18x + 24.

Equations for Total Cost

1. Total Cost of Regular Price: Ms. Chen can calculate the total cost for x people with the regular price by using the equation C = 22x. Here, C represents the total cost, and x is the number of people in the group.

2. Total Cost of Group Special: To calculate the total cost for x people with the group special, Ms. Chen would use the equation C = 18x + 24. C is still the total cost, x is the number of people, and 24 represents the additional fee for the private room.

By comparing the results of both equations for a specific number of people, Ms. Chen can determine which option is more cost-effective.

Option B is correct since both the lines given in option B have same slope so both the lines do not intersect each other and hence have no common solution.

The given equations are of the form

ax + by = c ......(1)

Slope for the equation of line is given by [tex](\dfrac{-a}{b} )[/tex]

We can  clearly see that in option B the lines given are

4x + 2y = 12 .......(2)

20x + 10y = 30....... (3)

Slope of equation (2)

[tex](\dfrac{-4}{2} )= -2[/tex]

Similarly slope of equation (3)

[tex](\dfrac{-20}{10} )= -2[/tex]

Which concludes that both are parallel to each other.

Since parallel lines can not have any common solution so  they never intersect each other. Hence option B is correct.

Step-by-step explanation:

This problem bothers on the law of indices

Given the expression

3^4x=27^x-3

We can also simplify it using the law

3^4x= 3^3(x-3)

Equating the powers we have

4x= 3(x-3)

Opening bracket

4x= 3x-9

Collecting like terms we have

4x-3x=-9

x=-9

Indices are used to show numbers that have been multiplied by themselves. They can also be used to represent roots, such as the square root, and some fractions. The laws of indices enable expressions involving powers to be manipulated more efficiently than writing them out in full.

Step-by-step explanation:

Consider the factors of the constant term ( - 42) which sum to give the coefficient of the x- term ( - 1)

The factors are - 7 and + 6, since

- 7 × 6 = - 42 and - 7 + 6 = - 1
