Answer:

When x = 5, y = 8.

Step-by-step explanation:

y is inversely proportional to X.

This means that we solve this using the rule of three for inversely proportional variables, that is, we apply line multiplication instead of cross multiplication.

y = 20, x = 2

Work out y when x = 5

20 - 2

x - 5

Applying line multiplication

[tex]5y = 40[/tex]

[tex]y = \frac{40}{5}[/tex]

[tex]y = 8[/tex]

When x = 5, y = 8.

Answer:

17 1/4 miles per hour

Step-by-step explanation:

First let's convert the mixed number to a fraction so it is easier to work with:

5 3/4 = (5*4 + 3)/4 = 23/4 miles.

Because she travelled it in a third of an hour, she could do it 3 times in 1 hour.

Because of this to get speed we divide the distance by the time taken.

23/4 divided by 1/3 is the same as saying 23/4 times 3:

(3*23)/4 = 69/4 = 17 1/4 miles per hour

Answer:

17 1/4

200,000 identification numbers are possible

Step-by-step explanation:

For the first digit, there are only two possible outcomes, 0 or 1.

For the next five digits, there are 10 possible outcomes(0,1,2,3,4,5,6,7,8,9).

How many identification numbers are possible?

Answer:

45 feet.

Step-by-step explanation:

Given that a model of a lighthouse has diameter 8 inches and height 18 inches, and the actual diameter of the lighthouse is 20 feet, in order to find its actual height, the following calculation has to be made:

20 feet = 240 inches

240 / 8 = 30

Scale ratio: 1:30

18 x 30 = 540

540 inches = 45 feet

Therefore, the actual height of the lighthouse is 45 feet.

Answer:

45 ft

Step-by-step explanation:

The number of way to select 2 employees from 40 is 40C2.

The number of way to select 2 employees from 22 is 22C2.

So the probability of the two employees having single-vision correction is just the number of ways to select the 22 employees (22C2) divided by the total number of ways to select 2 employees (40C2).

22C2 / 40C2 = 77/260

We can use the same technique for the bifocal employees.

18C2 / 40C2 = 51/260

Step-by-step explanation:

Answer:

a.) May or may not a polynomial function ( depends on c)

b.) Not a polynomial function.

c.) Not a polynomial function.

d.) It is a polynomial function.

Step-by-step explanation:

A polynomial function is of the form - [tex]a_{n}x^{n} + a_{n-1} x^{n-1} + a_{n-2} x^{n-2} + .....+ a_{1}x + a_{0}[/tex]

where n is positive integer and n[tex]\neq[/tex] 0

a.)

P(x) = 2x³ + 32 - 4x + 4c

It may or may not a polynomial function because we did not know about the constant c.

b.)

H(x) = 4[tex]x^{\frac{1}{2} }[/tex] - 3x⁴

It is not a polynomial function because [tex]\frac{1}{2}[/tex] is not integer.

c.)

G(x) = 2[tex]x^{-3}[/tex] + 5

It is not a polynomial function because -5 is not a positive integer.

d.)

F(x) = 2x³ - 5x + 33x²

It is a polynomial function.

The standard form of a polynomial is expressed as;

[tex]p(x)=a_nx^n+x_{n-1}x^{n-1}+x_{n-2}x^{n-2}+...[/tex]

The leading power of a polynomial must be greater than 2 and must be a positive integer.

a) For the polynomial [tex]P(x)=2x^3+3x^2-4x+4c[/tex]

This is a polynomial since the leading degree of the polynomial is greater than 2 and a positive integer.

b) For the function [tex]G(x)=2x^{-3}+5[/tex]

This is not a polynomial because the leading degree of the polynomial is a negative integer

c) For the function [tex]H(x) =4x^{\frac{1}{2} }-3x^4[/tex]

This is not a polynomial because the leading degree of the polynomial is a fraction.

d) For the polynomial [tex]P(x)=2x^3-5x+3+3x^2[/tex]

This is a polynomial since the leading degree of the polynomial is greater than 2 and a positive integer.

The worth of CD after 3 years will be $853.07 at the given rate of interest.

Compound interest is applicable when there will be a change in the principle amount after the given time period.

For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.

Given that,

Principle amount P = $750

Rate of interest R = 4.3%

Time period T = 3 years

Number of times interest compounded annually (n) = 12

The compound interest formula is given by;

A = P[1 + R/n]^nT

A = 750[ 1 + 4.3/1200]¹²⁽³⁾

A = $853.07

Hence "The worth of CD after 3 years will be $853.07 at the given rate of interest".

Answer:

x=56

Step-by-step explanation:

(2x-3)degrees+71 degrees=180 degrees because they are supplementary angles

This simplifies to 2x+68=180 because -3+71 is 68.

2x+68=180

2x=180-68

2x=112

x=112/2

x=56

Answer:

Omar could invite 19 friends.

Answer:

105%

Step-by-step explanation:

We'll analyse the question one step at a time

Let the original price be x.

Let y be the 40% increase

[tex]y =x + 40\% *x[/tex]

Express as decimal

[tex]y =x + 0.40 x[/tex]

[tex]y =1.40x[/tex]

Let z be the 25% off sale

[tex]z = (1 - 25\%) * y[/tex]

Express as decimal

[tex]z = (1 - 0.25) * y[/tex]

[tex]z = (0.75) * y[/tex]

[tex]z = 0.75y[/tex]

Substitute 1.40s for y

[tex]z = 0.75*1.40x[/tex]

[tex]z = 1.05x[/tex]

Express 1.05 as a fraction

[tex]z = 105\% * x[/tex]

The percentage is 105%

x = 6

Step-by-step explanation:

Since the given triangles ΔLMN and ΔCBQ are similar,

Their corresponding sides will be proportional.

[tex]\frac{LM}{CB}= \frac{MN}{BQ}=\frac{NL}{QC}[/tex]

Since, [tex]\frac{LM}{CB}= \frac{MN}{BQ}[/tex]

[tex]\frac{(5x-6)}{6}=\frac{52}{13}[/tex]

5x - 6 = 24

5x = 30

x = 6

Therefore, x = 6 will be the answer.

Answer:

The answer is 254.34 in².

Step-by-step explanation:

Given that the diameter is 2 times the radius. So the radius will be 9 in. Next, you have to find the area of circle, A = π × r² :

A = π × r²

Let π = 3.14, r = 9,

A = 3.14 × 9²

A = 254.34 in²
