Prove a||b

we know that

if two lines are parallel, then their slopes are equal

that means

If a||c and b||c

then

ma=mc and mb=mc

so

by the transitive property

if ma=mc and mb=mc

then

ma=mb

the slopes of the lines a and b are equal

therefore

lines a and b are parallel

Answer:

44 options

Step-by-step explanation:

In order to solve this problem you would simply need to multiply the options specifics together. In this scenario, these are the color and style. Therefore since the individual can choose from 11 colors and 4 styles you simply multiply 11 by 4. This is because every single color chosen has 4 styles to choose from,  meaning that all 4 styles also have 11 colors to choose from and vice versa.

11 * 4 = 44

Therefore, we see that an individual looking to buy a car has a total of 44 options to choose from.

In the question, we can draw the conclusion that, according to the formula, it will take them 10 days to get from City A to City B if they continue travelling at their current average speed of \(415 miles\)per day.

A formula is a set of mathematical signs and figures that demonstrate how to solve a problem.

Formulas for calculating the volume of \(3D\) objects and formulas for measuring the perimeter and area of \(2D\) shapes are two examples.

A formula is a fact or a rule in mathematical symbols. In most cases, an equal sign connects two or more values. If you know the value of one, you can use a formula to calculate the value of another quantity.

We need to know the average pace at which they went to figure how long it would take to get from City A to City B at the same rate.

total distance / time taken = average speed

\(415 miles\) per day \(2075/ 5\), it would take them \(10\) days to get from City A to City B because

Time taken = \(2075/415\) per days \(= 5 days\)

Therefore it will take them 10 days to get from City A to City B if they continue travelling at their current average speed of \(415 miles\)per day.

Answer:

The error is the use of wrong trigonometric ratio formula.

Sine was used instead of tangent.

It should be: \( tan(A) = \frac{36}{84} \)

Step-by-step explanation:

Side length, 36, is opposite to <A. Side length, 84, is the adjacent side. Therefore, the right trigonometric ratio formula to use is:

\( tan(A) = \frac{opposite}{adjacent} \)

\( tan(A) = \frac{36}{84} \)

\( A = tan^{-1}(\frac{36}{84}) \)

m<A ≈ 23°

The error made was the use of wrong trigonometric ratio formula.

Answer:

Step-by-step explanation:

36/78 = 0.46153,,,, nope.. not a choice

36/123 = 0.2926.... so the last answer looks good

The surface area of the composite figure is 2005 in².

To find the surface area of the composite figure, we need to calculate the sum of the areas of its individual components.

Let's break down the figure into its different parts and calculate the surface area step by step:

Rectangular Prism: The rectangular prism has dimensions of 20 in, 11 in, and 5 in. The surface area of a rectangular prism can be found by adding the areas of its six faces. The total surface area of the rectangular prism is given by:

Surface Area of Rectangular Prism = 2lw + 2lh + 2wh

Plugging in the values, we have:

Surface Area of Rectangular Prism = 2(20)(11) + 2(20)(5) + 2(11)(5) = 440 + 200 + 110 = 750 in²

Rectangular Prism: Another rectangular prism has dimensions of 19 in, 12 in, and 12 in. Following the same process as above, we can calculate the surface area of this rectangular prism:

Surface Area of Rectangular Prism = 2lw + 2lh + 2wh

Plugging in the values, we have:

Surface Area of Rectangular Prism = 2(19)(12) + 2(19)(12) + 2(12)(12) = 456 + 456 + 288 = 1200 in²

Base: The base is a rectangle with dimensions 11 in and 5 in. The surface area of a rectangle is given by the formula:

Surface Area of Rectangle = lw

Plugging in the values, we have:

Surface Area of Rectangle = (11)(5) = 55 in²

Finally, to find the total surface area of the composite figure, we add the surface areas of the individual components:

Total Surface Area = Surface Area of Rectangular Prism + Surface Area of Rectangular Prism + Surface Area of Rectangle

Total Surface Area = 750 in² + 1200 in² + 55 in² = 2005 in²

$3,708.33 is withheld monthly for state taxes.

Some states have a graduated income tax that involves a different tax rate for each of several levels of income. The tax rate increases as income increases.

Tax Withheld per Pay Period = Annual Tax Withheld/ Number of Pay Periods per Year

Here, we are given that Kerry McCarthy is a news traffic reporter with an annual gross pay of $44,500.

Thus, the Annual Tax Withheld = $44,500.

He is paid on a monthly basis ⇒ Number of Pay Periods per Year = 12

Hence, we get-

Tax Withheld per Pay Period = 44,500/ 12

= 3,708.33

Thus $3,708.33 is withheld monthly for state taxes.

By answering the presented question, we may conclude that To prepare ratio 5 litres of cold drink, we'll need 625 millilitres of pure fruit concentrate.

In mathematics, ratios demonstrate how frequently one number is contained in another. For example, if there are 8 oranges and 6 lemons in a fruit plate, the ratio of oranges to lemons is 8 to 6. In a similar vein, the orange-to-whole-fruit ratio is 8, whereas the lemon-to-orange ratio is 6:8. A ratio is an ordered pair of integers a and b represented as a / b, where b is not zero. A ratio is an equation that equates two ratios. For example, if there is one male and three girls (for every boy she has three daughters), 3/4 are girls and 1/4 are boys.

If the concentrate-to-water ratio is 1:7, it signifies that the final product requires 7 parts water for every 1 part concentrate. As a result, the total number of components in the combination is 1+7=8.

To produce 5 litres of the cold drink, we must first establish the quantity of concentrate necessary to make 8 parts, and then multiply this figure by 5 litres.

As a result, we need 1 part concentrate and 7 parts water to create 8 parts.

As a result, we require 1/8th of 5,000 millilitres of concentrate, or 625 millilitres.

To prepare 5 litres of cold drink, we'll need 625 millilitres of pure fruit concentrate.

Elise's number is 38.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

If you subtract 17 from my number and multiply the difference by negative 6​, the result is negative 126​.

let the number be x

So, the equation can be

-6(x- 17) = -126

Now, solving for x

Divide by -6

x-17= 21

Add 17 both side

x- 17+ 17 = 21 + 17

x= 38

Answer:

D. 3

Step-by-step explanation:

Assuming the model represents an equation, the following can be deduced:

On the left side of the equation, the model shows we have 3 "x's", and 6 "1's". Let this represent:

3x + 6

On the right side of the equation, we have 2 "x's" and 9 "1's". Let this represent:

2x + 9.

The model would represent the equation below:

\( 3x + 6 = 2x + 9 \)

Solve for x

\( 3x + 6 - 2x = 2x + 9 - 2x \) (Subtracting 2x from both sides of the equation)

\( x + 6 = 9 \)

\( x + 6 - 6 = 9 - 6 \) (subtracting 6 from both sides of the equation)

\( x = 3 \)

Answer:

  not equivalent; signs don't match

Step-by-step explanation:

Apparently, you want to compare the expressions ...

The distributive property allows you to eliminate parentheses by multiplying each term inside parentheses by the factor outside.

When we do that to the first expression, we get ...

  -0.5(3x +5) = (-0.5)(3x) +(-0.5)(5) = -1.5x -2.5

Note that the signs of the terms inside parentheses are the same, and the signs of the terms after removing parentheses are the same. (Both terms have their signs changed by the negative factor multiplying the parentheses.)

The expanded expression -1.5x -2.5 is not equivalent to -1.5x +2.5, which has terms of different signs.

Answer:

The zeroes of the equation are -2 and -6.

Step-by-step explanation:

(x + 2)(x + 6) = 0

=> x = -2, -6
