Sophia earned $18 for working 2 1/4 hours. How much did she earn per hour?

Answer:

8,000

Step-by-step explanation:

you have to move the decimal to the right 3 times. so you take 8 and move the decimal 3 times. which gives you 8000.

or 8,000

The solution is: 8x10^3 in standard notation is 8,000.

Here, we have,

given that,

the expression is: 8 x 10^3

now, we have to write 8 x 10^3 in standard notation.

we know that,

A standard notation is a form of writing a given number, an equation, or an expression in a form that follows certain rules.

For example, 4.5 billion years is written as 4,500,000,000 years.

we know,

To change a number from scientific to standard notation, move the decimal point the number of places shown in the exponent of 10.

here, we have,

8 x 10^3

= 8 x 1000

so, we have to move the decimal to the right 3 times. so we take 8 and move the decimal 3 times. which gives 8000.

we get,

8 x 10^3 = 8000

Hence, The solution is: 8 x 10^3 in standard notation is 8000.

Answer: 43 should be divided into 0.37 to find “x”.

Step-by-step explanation:

Step-by-step explanation:

Let x be the amount of tickets sold for $25 and y be the amount of tickets sold for $40, since there are 6000 seats theatre then;

x+y = 6000 .............. 1

If x tickets cost $25 and y tickets are sold for $40 with total revenue of ​$174,000, then;

25x + 40y = ​174,000................ 2

From 1, x = 6000-y ............ 3

Substitute equation 3 into 2:

25x + 40y = ​174,000.

25(6000-y) + 40y = ​174,000

150,000-25y + 40y = 174,000

150,000+15y = 174,000

15y = 174,000-150,000

15y = 24,000

y = 24,000/15

y = 1600

Substitute y = 1600 into equation 3:

x = 6000-y

x = 6000-1600

x = 4400

Hence 4400 $25 tickets and 1600 $40 tickets must be sold to generate a revenue of $174,000

Answer:    Éstos son los pasos para usar la estrategia del valor absoluto. Para sumar dos enteros con el mismo signo, suma sus valores absolutos. Luego, coloca el mismo signo de los dos enteros originales a la respuesta. Para sumar dos enteros con signos diferentes, resta el valor absoluto menor al valor absoluto mayor.

Step-by-step explanation: Ojalá esto ayude !

Answer:

El valor absoluto de un número consiste en su valor, sin importar su signo. Cuando tomamos el valor absoluto de un número, éste es siempre positivo o cero. ... Por ejemplo, el valor absoluto de 5 es 5. El valor absoluto de -5 es también 5.

Answer:

a. R(x) = 90x b. -1500 -10x - 0.2x c. 148

Step-by-step explanation:

a. Since we have x jackets produced at a rate of  $90 per jacket, the revenue function, R(x) = rate × number of jackets = 90 × x = 90x

R(x) = 90x

b. Since the cost function is C(x) = 1500 + 100x + 0.2x, the profit function P(x) = Revenue function - cost function = R(x) - C(x) = 90x - (1500 + 100x + 0.2x)

P(x) = -1500 + 90x - 100x - 0.2x

P(x) = -1500 - 10x - 0.2x

c. For a profit, P(x) > 0

-1500 - 10x - 0.2x > 0

0.2x + 10x + 1500 < 0

10.2x + 1500  < 0

10.2x < -1500

x < -1500/10.2

x < -147.05

x < -147

So, ABX Clothing needs to produce greater than 147 jackets to make a profit. So, they need to make 148 jackets to make a profit.

The number of red and white stripes = 666

Given, A model of the American flag was made out of 1,776 colored tiles.

The star field took 444 blue tiles.

The rest of the tiles were split evenly to form the red and white stripes.

Number of red or white stripes =  (Total number of colored tiles - number of blue tiles)/2  

= (1776 - 444)/2

= (1332)/2

Answer:

x > 2

Step-by-step explanation:

Original Equation:

4x + 0.5(2x + 4) > 12

0.5 multiplied by 2x = 1x

0.5 multiplied by 4 = 2

4x + 1x + 2 > 12

4x + 1x = 5x

5x + 2 > 12

Subtract 2 from both sides.

5x > 10

Divide both sides by 5

x > 2

Answer:

Base area = 36

Volume of the pyramid = 132

Step-by-step explanation:

Volume of a pyramid = Base Area × Height/3

Base area = Length × Length (since base of the pyramid is a square)

Given the side length of the square = 6

Base area = 6×6

Base area = 36

Given height of pyramid =11

Volume of the pyramid = 36×11/3

Volume of the pyramid = 12×11

Volume of the pyramid = 132

Answer:

The minimum cost for this number of passengers is Rs.36.05

Step-by-step explanation:

The cost to build an amusement park ride by a certain contractor is represented by the function:

[tex]Cost = 2x^2 - \frac{10}{x}+ 36y + 25[/tex]

x : Number of people able to be on the ride at once.

Differentiate the function w.r.t x

[tex]\frac{\partial cost}{\partial x}=4x-(\frac{-10}{x^2})=0[/tex]

[tex]x^3=\frac{-5}{2}[/tex]

x=-1.3572

Differentiate the function w.r.t y

[tex]\frac{\partial cost}{\partial y}=36=0[/tex]

Minimum cost =[tex]2x^2 - \frac{10}{x}+ 36y + 25[/tex]

Minimum cost = [tex]2(-1.3572)^2 - \frac{10}{(-1.3572)}+ 36(0) + 25[/tex]

Minimum cost = 36.05

Hence the minimum cost for this number of passengers is Rs.36.05

The answer is y=5/4x-5

Step-by-step explanation:

The required equation of the line that goes through the point (4, 0) and has a slope of 5/4 is y = 5/4x - 5.

In the equation intercept is the value of the linear function where either of the variables is zero.

The equation of a line with slope m and passing through the point (x₁, y₁) can be found using the point-slope formula:

y - y₁ = m (x - x₁)

Plugging in m = 5/4, x₁ = 4, and y₁ = 0, we get:

y - (0) = 5/4 (x - (4))

Simplifying, we get:

y = 5/4x - 5

Thus,  the equation of the line is y = 5/4x - 5

Answer:

No, I disagree

Step-by-step explanation:

2n^4

let's put n to a real number. How about 2.

(2*2)^4=256

(2*4)^4=4096

No, I disagree, it doesn't double the expression.

Disagree. When you double the value of n, you quadruple the value of the expression.

In mathematics, proportionality indicates that two quantities or variables are related in a linear manner. If one quantity doubles in size, so does the other.

Now the given expression is,

2n^4

Let y = 2n^4

Since 2 is the constant and y and n are variables.

Thus we can write,

y ∝ n^4

This means when value of y increases one time, the value of n increases 4 times.

Thus,you Disagree. When you double the value of n, you quadruple the value of the expression.

t ≤ 3 ; kindly check explanation for more explanation

Step-by-step explanation:

Given that :

Number of tulip (t) =?

Cost of bulb = $1.50

Pot for each bulb purchased at =$1.25

Bag of potting soil = $10.00

Number of tulip bulb that can be purchased without spending more than $20

Cost of tulip bulb = [(cost per bulb + cost per pot) * number purchased (t) + cost of bag of potting soil]

Cost = [(1.50 + 1.25)t + 10]

If spending should not exceed $20

2.75t + 10 ≤ 20

2.75t ≤ 20 - 10

2.75t ≤ 10

t ≤ 10/2.75

t ≤ 3.64

He cannot purchase more than 3 tulip bulbs

Anika cannot buy exactly enough tulip bulbs an pot to spend the full $20 because the number obtained is a fraction and not a whole number.
