Answer:

The width and length of the old card are 2 inches and 4 inches respectively.

Step-by-step explanation:

The given scale factor, [tex]C=\frac{5}{4}[/tex]

She draws is a rectangle by using the scale factor of C.

The width of her drawing, [tex]b=2\frac{1}{2}[/tex] [tex]=\frac{5}{2}[/tex] inch, and

the length of the drawing, [tex]a=5[/tex] inch.

Let [tex]a'[/tex] and [tex]b'[/tex] be the length and width of her reference business card (the old one as mentioned).

[tex]\text{Scale factor}=\frac{\text{New dimension}}{\text{Reference dimention}}[/tex]

Here, the dimension is the length of the sides of rectangular cards.

So, [tex]C=\frac{a}{a'}[/tex] and [tex]C=\frac{b}{b'}[/tex]

[tex]\Rightarrow \frac{5}{4}=\frac{5}{a'}[/tex]

[tex]\Rightarrow a'=4[/tex] inch

and  [tex]\frac{5}{4}=\frac{5/2}{b'}[/tex]

[tex]\Rightarrow b'=2[/tex] inch

So, the old business card is of the dimensions 2 inches by 4 inches, which are the correct dimensions.

Actually, the print shop multiplied he scale-factor, C, with the new scaled length to get the reference length (lengths of original old card), which was the error. In, fact, as already described earlier, the new dimensions can be obtained by multiplying the scale-factor, C, with the reference dimensions.

Answer:

C. The scale factor is a fraction so the scale drawing is a reduction, and the original card is 2 inches by 4 inches.

Step-by-step explanation:

Given the expression :

Total cost after tax = 0.08(50h) + 50h

a. What part of the expression represents the amount of tax Deborah has to pay? Explain

0.08(50h) represents Tha amount of tax Deborah has to pay. This can be interpreted as :

Recall;

Tax amount = tax rate * cost

Cost of repair = 50h = 50 per hour

Tax rate = 0.08 = 8% of the total cost;

Hence; 0.08(50h) = tax Deborah has to pay.

What would the expression be if the company charged Deborah $45 per hour to repair the computer (plus tax)?

If she was charged $45 per hour plus tax. Expression becomes ;

Total cost after tax = 0.08(45h) + 45h

= 3.6h + 45h

= 48.6h

Answer:

c= e/d-ab/d

Step-by-step explanation:

The equation ab + cd = e is solved for the variable 'c' will be c = (e + ab) / d.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The equation is given below.

ab + cd = e

Simplify the equation for c, then we have

ab + cd = e

cd = e + ab

c = (e + ab) / d

The equation ab + cd = e is solved for the variable 'c' will be c = (e + ab) / d.

Answer:

[tex]R=\frac{1}{2} \sqrt{\frac{A}{\pi }}[/tex]

Step-by-step explanation:

To solve an equation for one of its value

∵ A = 4πR²

→ Underline R

∴ A = 4πR²

→ Move 4π to the other side by dividing both sides by 4π

∵ [tex]\frac{A}{4\pi }=\frac{4\pi R^{2} }{4\pi }[/tex]

∴ [tex]\frac{A}{4\pi }=R^{2}[/tex]

→ To find R take √  for both sides

∴ [tex]\sqrt{\frac{A}{4\pi }}=\sqrt{R^{2} }[/tex]

→ You can simplify  [tex]\sqrt{\frac{1}{4}}[/tex] to [tex]\frac{1}{2}[/tex]

∴ [tex]\frac{1}{2} \sqrt{\frac{A}{\pi }}=R[/tex]

→ Switch the two sides

∴ [tex]R=\frac{1}{2} \sqrt{\frac{A}{\pi }}[/tex]

Step-by-step explanation:

" First four terms " means :

t(1) , t(2) , t(3) , t(4)

[tex]t(1) = a(1) = 5(1) - 1 = 5 - 1 = 4 \\ t(2) = a(2) = 5(2) - 1 = 10 - 1 = 9 \\ t(3) = a(3) = 5(3) - 1 = 15 - 1 = 14 \\ t(4) = a(4) = 5(4) - 1 = 20 - 1 = 19 \\ \\ t(1) = 4 \\ t(2) = 9 \\ t(3) = 14 \\ t(4) = 19[/tex]

Answer:

Step-by-step explanation:

Given the expression [tex]\frac{720,800}{x} = 7.208[/tex], we are to find the value of with powers of 10.

From the equation:

[tex]\frac{720,800}{x} = 7.208[/tex]

cross multiply

[tex]720,800 = 7.208x\\7.208x = 720,800[/tex]

divide both sides by 7.208

[tex]\frac{7.208x}{7.208} = \frac{720,800}{7.208} \\x = 100,000[/tex]

express x in powers of 10

[tex]x = 10 * 10 * 10 * 10* 10\\x = 10^5[/tex]

Similarly given the equation [tex]\frac{720,800}{y} = 72.08[/tex]

From the equation:

[tex]\frac{720,800}{x} = 72.08[/tex]

cross multiply

[tex]720,800 = 72.08x\\72.08x = 720,800[/tex]

divide both sides by 7.208

[tex]\frac{72.08x}{72.08} = \frac{720,800}{72.08} \\x = 10,000[/tex]

express x in powers of 10

[tex]x = 10 * 10 * 10 * 10\\x = 10^4[/tex]

For the equation [tex]\frac{720,800}{z} = 720.8[/tex]

From the equation:

[tex]\frac{720,800}{z} = 720.8[/tex]

cross multiply

[tex]720,800 = 720.8z\\720.8z = 720,800[/tex]

divide both sides by 7.208

[tex]\frac{72.08z}{720.8} = \frac{720,800}{720.8} \\z = 1,000[/tex]

express x in powers of 10

[tex]z = 10 * 10 * 10\\z = 10^3[/tex]

The dividing 720,800 by 101010 successively four times in the parentheses results in 720.8

To complete the equations using powers of 101010:

720,800 ÷ (720,800 ÷ 720,800) = 7.208 = 7.208 equals 7.208

Explanation: Dividing 720,800 by 720,800, and then dividing the result by 720,800, yields 7.208.

720,800 ÷ (720,800 ÷ (720,800 ÷ 101010)) = 72.08 = 72.08 equals 72.08

Explanation: Dividing 720,800 by 101010, and then dividing 720,800 by the result, and finally dividing 720,800 by the new result, gives us 72.08.

720,800 ÷ (720,800 ÷ (720,800 ÷ (720,800 ÷ 101010))) = 720.8 = 720.8 equals 720.8

Answer:

0.285

Step-by-step explanation:

Total peoples are, n=130

Number of people who use gym =65

Number of people who use swimming pool =51

Number of people who use the track =44

Number of people who use the gym and the pool =15

Number of people who use the pool and the track =14

Number of people who use the gym and the track =10

Number of people who use the gym, the pool, and the track =1

So, the number of people who use the gym and the pool =15-1=14

The number of people who use the pool and the track =14-1=13

The number of people who use the gym and the track =10-1=9

Now, the people who use at least two facilities are the people who use 2 or 3 facilities, which is 14+13+9+1=37.

So, the number of favorable outcomes =37

Total number of sample space, n=130

Hence, the probability, P, that the 1 randomly selected person uses at least 2 facilities is as follows:

The product to this problem is simplified to:  [tex]1+14f+49f^{2}[/tex]

Step-by-step explanation:

1) First place out what was given:

[tex](-1 -7f)^{2}[/tex]

Squared is the same thing as multiply to itself, so you would create a pair of

[tex](-1 -7f)^{2}[/tex]  

(For example, if you said: [tex]x^{2}[/tex] it is the same as saying or putting: x · x)

2) Then create your pair which would look like:

[tex](-1 -7f)(-1 -7f)[/tex]

3) Next step is to do the FOIL method

(Like how it is shown in the picture, we will do this method and create one whole expression!)

4) Creating and combining your expression into one whole problem, by using the foil method.

[tex](-1 -7f)(-1 -7f)[/tex]

First - F: [tex]1[/tex]

Outside - O: [tex]7f[/tex]

Inside - I: [tex]7f[/tex]

f(2)= -3

Step-by-step explanation:

f(x)= 2 [x-3.5]

f(2)= 2[2-3.5]                         substitute all of your "x" for the number "2"     f(2)=2[ -1.5]                                                2-3 is -1.5

f(2)= -3                                                 2 times -1.5 is -3

The value of f(2)= -3

Since f(x) = 2[[X-3.5]

Answer:

Adriana debe subirse durante 7.5 minutos, Luis durante 24 minutos y Ramiro 28.5 minutos.

Step-by-step explanation:

Asumamos en primer lugar que los tres amigos rentan la cuatrimoto durante una hora, entonces cada persona utiliza la cuatrimoto en proporción al dinero. A continuación, obtenemos el tiempo estimado por cada usuario a partir de una regla de tres simple:

[tex]\Delta t = \frac{c_{a}}{c_{r}}\cdot (60\,min)[/tex]

Donde:

[tex]\Delta t[/tex] - Tiempo de uso de la cuatrimoto, medido en minutos.

[tex]c_{a}[/tex] - Dinero aportado por el usuario, medido en pesos.

[tex]c_{r}[/tex] - Coste de renta de la cuatrimoto, medido en pesos.

Entonces calculamos el tiempo correspondiente a cada amigo:

Adriana ([tex]c_{a} = \$\,50[/tex], [tex]c_{r} = \$\,400[/tex])

[tex]\Delta t = \frac{\$\,50}{\$\,400}\times 60\,min[/tex]

[tex]\Delta t = 7.5\,min[/tex]

Luis ([tex]c_{a} = \$\,160[/tex], [tex]c_{r} = \$\,400[/tex])

[tex]\Delta t = \frac{\$\,160}{\$\,400}\times 60\,min[/tex]

[tex]\Delta t = 24\,min[/tex]

Ramiro ([tex]c_{a} = \$\,190[/tex], [tex]c_{r} = \$\,400[/tex])

[tex]\Delta t = \frac{\$\,190}{\$\,400}\times 60\,min[/tex]

[tex]\Delta t = 28.5\,min[/tex]

Adriana debe subirse durante 7.5 minutos, Luis durante 24 minutos y Ramiro 28.5 minutos.
