Jack bought a car for $29,000. He sold it for $10,000 3 years later. What is the percentage loss that Jack made?

Answer and Step-by-step explanation:

Let us assume the number of calls be x

So

For Plan 1

Total monthly charges is $24 for unlimited calls

For Plan 2

There is a charge of $16 and $0.04 per call

We can write as

= 0.04x + $16

a)  Now the inequality equation is

0.04x + $16 > $24

0.04x > $8

x > 200

b)   Now if there are more than 200 calls than Plan 1 is more economical as compared with plan 2

Answer:

[tex]x\approx12.1940[/tex]

Step-by-step explanation:

So we want to find the value of x.

To do so, we can use the standard trigonometric ratios.

Focus on Angle B. The opposite side is 8, and the hypotenuse is x. Therefore, we can use the sine function.

Recall that sine is:

[tex]\sin(x)=opp/hyp[/tex]

Substitute 41 for x, 8 for the opposite, and x for the hypotenuse:

[tex]\frac{\sin(41)}{1}=\frac{8}{x}[/tex]

Cross multiply:

[tex]8=x\sin(41)[/tex]

Divide both sides by sin(41):

[tex]x=8/\sin(41)[/tex]

Use a calculator:

[tex]x\approx12.1940[/tex]

Answer:

Step-by-step explanation:

the slope of a function m: y2-y1/x2-x1

m=-3-(-3)/5-(-5)

m=0/10=0

The slope of the line drawn passing through (- 5, - 3) and (5, - 3) is zero, so option C is correct.

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Given:

straight line drawn passing through (- 5, - 3) and (5, - 3)

Calculate the slope of the line as shown below,

[tex]m = y_2 - y_1 / x_2 - x_1[/tex]

m = slope

m = -3 - (-3) / 5 - (-5)

m = 0 / 10

m = 0

Therefore, the slope of the line drawn passing through (- 5, - 3) and (5, - 3) is zero.

Answer:

You can put 1 + 6 into parentheses to make the answer correct.

Step-by-step explanation:

5 × 4 - (1 + 6) = 13

5 × 4 - (7) = 13

20 - (7) = 13

13 = 13

Answer:

5 • 4 - (1+6)=13

Step-by-step explanation:

5 • 4 - 1+6=13

Add parentheses to make this true

5 • 4 - (1+6)=13

Using PEMDAS

Parentheses first

5 • 4 - 7=13

Then multiply

Answer:

-6x + 3

Step-by-step explanation:

-3(2x - 1)

We use distributive property

so we mulitply the number that is outside of the paraenthesis (-3), to the numbers on the inside (2x - 1)

-3 × 2x = -6x

-3 × -1 = 3

So we have:

-6x + 3

And we cannot combine them so that is the answer.

UV=4 is the solution

The value of UV = 4.

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S.

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators. An equation can be formed without these as well, for example, 5 + 10 = 15. This is an arithmetic equation with no variables.

Given:

UV = 4x, VW = 3x, and UW = 7

UW= UV + VW

7 = 4x + 3x

7 = 7x

x= 7/7

x=1

Hence, UV = 4

Answer:

(4,7), (6,13), and (5,10)

Step-by-step explanation:

To determine if an ordered pair is a solution, substitute the coordinates in and check to see if they are true:

(2,2)

[tex]y=3x-5\\(2)\stackrel{?}{=}3(2)-5\\2\stackrel{?}{=}6-5\\2\neq1[/tex]

Thus, (2,2) is not a solution.

(4,7)

[tex]y=3x-5\\(7)\stackrel{?}{=}3(4)-5\\7\stackrel{?}{=}12-5\\7\stackrel{\checkmark}{=}7[/tex]

Thus, (4,7) is a solution.

(6,13)

[tex]y=3x-5\\(13)\stackrel{?}{=}3(6)-5\\13\stackrel{?}{=}18-5\\13\stackrel{\checkmark}{=}13[/tex]

Thus, (6,13) is also a solution.

Lastly, (5,10)

[tex]y=3x-5\\10\stackrel{?}{=}3(5)-5\\10\stackrel{?}{=}15-5\\10\stackrel{\checkmark}{=}10[/tex]

Thus, (5,10) is also a solution.

Answer:

x = 4

Step-by-step explanation:

RT = RS + ST

RT = 36

RS + ST = 36

6x + 1  + x + 7 = 36

6x + x + 1 + 7 = 36  {Combine like terms}

7x + 8 = 36   {Subtract 8 from both sides}

7x + 8 - 8 = 36 - 8

7x = 28   {Divide both sides by 7}

7x/7 = 28/7

x = 4

Answer:

2⁸ > 2.38 × 10² > 6³ > 2.16 × 10¹ > [tex]\sqrt{300}[/tex], 300%

Step-by-step explanation:

Given numbers are,

2.38 × 10², √300, 2⁸, 300%, 6³, 2.16 × 10¹

We have to arrange these numbers in the decreasing order(from greatest to least)

2.38 × 10² = 2.38 × 100 = 238

√300 = 10√3 ≈ 17.32

2⁸ = 256

300% = [tex]\frac{300}{100}[/tex] = 3

6³ = 216

2.16 × 10¹ = 21.6

Therefore, decreasing order (from the greatest to least) will be,

256 > 238 > 216 > 21.6 > 17.32 > 3

2⁸ > 2.38 × 10² > 6³ > 2.16 × 10¹ > [tex]\sqrt{300}[/tex], 300%

d. 2(x-11)

The algebraic expression that represents the word description: The product of two and the difference between a number and eleven is 2(x - 11). Hence, option d is the right choice.

An algebraic expression is a combination of variables and constants, as well as algebraic operations (addition, subtraction, etc.). Terms are the building blocks of expressions.

We are asked to find the algebraic expression that represents this word description The product of two and the difference between a number and eleven.

We let the unknown number be x.

We are said that the expression is the product of two and the difference between a number and eleven.

The difference between a number and eleven can be written as x - 11.

Now we need the product of this and two, that can be written as:

2(x - 11).

∴ The algebraic expression that represents the word description: The product of two and the difference between a number and eleven is 2(x - 11). Hence, option d is the right choice.
