Answer:

1mm:3cm

Step-by-step explanation:

8mm:24cm

----------------     = 2mm:6cm

       4

2mm:6cm  divided by 2 equals 1mm: 3cm

The required simplest form of 8mm; 24cm is 1mm; 3cm.

We have to determine, the simplest form of 8 mm: 24 cm.

To obtain the simplest form of the equation calculation must be done in a single unit following all the steps given below.

The ratio is just a way to compare two quantities while the proportion is an equation that shows that two ratios are equivalent.

Here, 8 mm: 24 cm.

Therefore,

[tex]8mm \ ; 24cm[/tex]

Divided by 8 both sides,

[tex]= \dfrac{8mm}{24cm}\\\\= \dfrac{1mm}{3cm}[/tex]

Hence, The required simplest form of 8mm; 24cm is 1mm; 3cm.

Answer:

mean; the average of George's scores is the mean = 83.4

Step-by-step explanation:

The value that best describes George's scores is the mean that has a value of 83.4.

Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number. The mean makes use of all the data in the data set.

Mean = sum of the numbers / total number

(70+  92 + 70 + 90 +  95) / 5 = 83.4.

Answer:

x = 1

Step-by-step explanation:

[tex]\sqrt[3]{3x - 2} = 1[/tex]        Cube both sides of the equation

3x - 2 = 1

3x = 3

x = 1

Check:  [tex]\sqrt[3]{3(1) - 2} = \sqrt[3]{3 - 2} = \sqrt[3]{1} = 1[/tex]   Since x = 1 makes the original equation true, then x = 1 is the solution.

The correct solution for the given equation is x = 1.

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given is a cubic equation, [tex]\sqrt[3]{3x-2}[/tex] = 1

Solving for x,

[tex]\sqrt[3]{3x-2}[/tex] = 1

Cubing both the sides,

([tex]\sqrt[3]{3x-2}[/tex])³ = 1

3x - 2 = 1

3x = 3

x = 1

Hence, the correct solution for the given equation is x = 1.

Answer: red marbles = 140

White marbles = 98

Step-by-step explanation:

Let the number of white marbles be represented by x

Since there are 42 more red marbles in a jar than there are white marbles, red marbles will be: = x + 42

Since there are 238 marbles in the jar, this can be represented in an equation as:

x + x+42 = 238

2x + 42 = 238

2x = 238 - 42

2x = 196

x = 196/2

x = 98

White marbles = 98

Red marbles = x + 42

= 98 + 42

= 140

Answer:

3

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

Each of the green lines has 3 times the length of the corresponding blue line.  Thus the dilution factor is 3.

Slope can be found using the following equation:

slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

7) Let:

[tex](x_1 , y_1) = (-1 , -11)\\(x_2 , y_2) = (-6 , -7)[/tex]

Plug in the corresponding numbers to the corresponding variables:

m = [tex]\frac{-7 - (-11)}{-6 - (-1)} = \frac{-7 + 11}{-6 + 1} = \frac{4}{-5} = -\frac{4}{5}[/tex]

Slope: [tex]-\frac{4}{5}[/tex]

8) Let:

[tex](x_1 , y_1) = (-7 , -13)\\(x_2 , y_2) = (1 , -5)[/tex]

Plug in the corresponding numbers to the corresponding variables:

m = [tex]\frac{-5 - (-13)}{1 - (-7)} = \frac{-5 + 13}{1 + 7} = \frac{8}{8} = 1[/tex]

Slope: [tex]1[/tex]

9) Let:

[tex](x_1 , y_1) = (-5 , 3)\\(x_2 , y_2) = (8 , 3)[/tex]

Plug in the corresponding numbers to the corresponding variables:

m = [tex]\frac{3 - (3)}{8 - (-5)} = \frac{0}{8 + 5} = \frac{0}{13} = 0[/tex]

Slope: [tex]0[/tex]

10) Let:

[tex](x_1 , y_1) = (3 , -2)\\(x_2 , y_2) = (15 , 7)[/tex]

Plug in the corresponding numbers to the corresponding variables:

m = [tex]\frac{7 - (-2)}{15 - 3} = \frac{7 + 2}{15 - 3} = \frac{9}{12}[/tex]

Simplify the slope. Divide common factors from both the numerator and denominator:

[tex](\frac{9}{12})/(\frac{3}{3} ) = \frac{3}{4}[/tex]

Slope: [tex]\frac{3}{4}[/tex]

11) Let:

[tex](x_1 , y_1) = (-5 , -10)\\(x_2 , y_2) = (-5 , -1)[/tex]

Plug in the corresponding numbers to the corresponding variables:

m = [tex]\frac{-1 - (-10)}{-5 - (-5)} = \frac{-1 + 10}{-5 + 5} = \frac{9}{0} =[/tex] undefined.

Slope: undefined

12) Let:

[tex](x_1 , y_1) = (-4 , -2)\\(x_2 , y_2) = (-12, 16)[/tex]

Plug in the corresponding numbers to the corresponding variables:

m = [tex]\frac{16 - (-2)}{-12 - (-4)} = \frac{16 + 2}{-12 + 4} = \frac{18}{-8} = -\frac{18}{8} = ((-\frac{18}{8})/( \frac{2}{2}) = -\frac{9}{4}[/tex]

Slope: [tex]-\frac{9}{4}[/tex]
