Responder:

x = 1100

y = 2350

z = 6550

Explicación paso a paso:

Dejemos que los 3 números = x, y, z (dispuestos en orden ascendente)

Diferencia entre los dos más pequeños:

y - x = 1250

y - 1250 = x - - - (1)

Diferencia entre los dos más grandes:

z - y = 4200

z = 4200 + y - - - (2)

x + y + z = 10000 - - - (3)

Sustituya (1) y (2) en (3)

y - 1250 + y + 4200 + y = 10000

3 años + 2950 = 10000

3 años = 7050

y = 2350

x = 2350-1250

x = 1100

z = 4200 + 2350

z = 6550

Answer:

4 hours

Step-by-step explanation:

Minuse $25 dollors from $73 and get $48 then divide 48 by 12 you get your hours

12h+25=73 is the equation represents the number of hours,  Erica rented the scooter

Two or more expressions with an Equal sign is called as Equation.

Given,

Erica rented a scooter for $12 per hour plus a $25 gas fee.

Erica spent a total of $73 to rent the scooter.

Let h represents the number of hours

$25 is a constant.

Twelve times of h plus twenty five equal to seventy three

12h+25=73

12h+25=73 is the equation represents the number of hours,  Erica rented the scooter

Answer:

k=−15

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(3k−10)+1=8( 3 /2 k+2)

(3)(3k)+(3)(−10)+1=(8)( 3 /2 k)+(8)(2)(Distribute)

9k+−30+1=12k+16

(9k)+(−30+1)=12k+16(Combine Like Terms)

9k+−29=12k+16

9k−29=12k+16

Step 2: Subtract 12k from both sides.

9k−29−12k=12k+16−12k

−3k−29=16

Step 3: Add 29 to both sides.

−3k−29+29=16+29

−3k=45

Step 4: Divide both sides by -3.

−3k /−3 = 45 /−3

k=−15

Answer:

61 tickets

Step-by-step explanation:

It is given that,

The total profit from the Spanish club fund-raiser varies directly with the number of dinner tickets sold.

If the sale of 22 tickets results in a profit of $253.

Profit in 1 ticket = [tex]\dfrac{253}{22}=\$11.5[/tex]

Let x tickets are sold in order to reach the fund-raising goal of $700.

[tex]x=\dfrac{22}{253}\cdot700\\\\=\$60.86[/tex]

or

= 61 tickets

Hence, 61 tickets must be sold to reach the fund-raising goal of $700.

Answer:

1) Domain: -∞ < x < +∞

2) Range: y > 0

3) y intercept: (0, 200)

4) Asymptote: y = 0

5) The growth rate; r = 0.08

6) The growth factor = 1.08

7) End Behavior: As x → -∞, f(x) → 0

8) End Behavior: As x → +∞, f(x) → +∞

Step-by-step explanation:

1) The domain of the function is given as the x values for which the function is valid which includes from -∞ < x  to +∞

2) The range of the function, are the range of the output values of the function for the given range of the input values

For the function, f(x) = 200·(1.08)ˣ, we have, f(x) = y > 0, for all values of x

3) The y-intercept is the value of y, when x = 0, given as follows;

y intercept = f(0) = 200·(1.08)⁰ = 200 × 1 = 200

4) The asymptote is the line that the function approaches but never reaches

In the question, as x tends to -∞, the function f(x) approaches 0. Therefore, f(x) = y = 0 is the asymptote of the function

5) The growth rate of an exponential function, y = a(1 + r)ˣ is r

Therefore, for the function, 200·(1.08)ˣ, which is equivalent to 200·(1 + 0.08) ˣ, the growth rate = 0.08

6) The growth factor of an exponential function, y = a(1 + r)ˣ is (1 + r)

Therefore, for the function, 200·(1.08)ˣ, which is equivalent to 200·(1 + 0.08) ˣ, the growth factor = (1 + 0.08) = 1.08

7) The end behavior as x tends to -∞, [tex]f(x) = y= 200 \cdot (1.08) ^{-\infty} \rightarrow 0[/tex]

8) The end behavior as x tends to +∞, [tex]f(x) = y= 200 \cdot (1.08) ^{-#+\infty} \rightarrow + \infty[/tex]

The texts that complete the blanks are:

The domain

The domain of an exponential function is all set of real numbers.

So, the domain is: -∞ < x < +∞

The range

The range of an exponential function is always greater than 0.

So, the range is y > 0

The y-intercept

This is when x = 0.

So, we have:

[tex]f(x) = 200(1.08)^x[/tex]

This gives

[tex]f(0) = 200(1.08)^0[/tex]

[tex]f(0) = 200[/tex]

So, the y-intercept is (0,200)

The asymptote

This is the line that is close to the function but is not on the function.

The range is:

y > 0.

So, the asymptote is y = 0

The growth rate and the growth factor

The function is given as:

[tex]f(x) = 200(1.08)^x[/tex]

The growth factor is 1.08, while the growth rate (r) is calculated as:

[tex]r = 1.08 - 1[/tex]

[tex]r = 0.08[/tex]

Hence, the growth rate is 0.08, and the growth factor is 1.08

The end behavior

The end behavior of an exponential growth function is:

a x → -∞, f(x) → 0 and as x → +∞, f(x) → +∞

Answer:

Alfred ate 24 hot dogs.

Step-by-step explanation:

Let the number of hot dog ate by Olafs be represented by b.

Since Olafs eats five fewer than triple the hot dogs Alfred eats, and Alfred ate a hot dogs. This can be expressed in a mathematical equation as follows;

b = 3a - 5

But Olafs eats 67 hot dogs, so that b = 67. Thus;

b = 3a - 5

67  = 3a - 5

67 + 5 = 3a

3a = 72

divide both sides by 3 to have;

a = [tex]\frac{72}{3}[/tex]

a = 24

Alfred ate 24 hot dogs.

Answer:

Y= 3

Step-by-step explanation:

To do this u can subtract -4 on each side. Whatever u do to one side of the equal sign u have to do to the other.

+4 and -4 cancel each other out

-11 + -4 = -15

The next step is to divide -5y on each side.

-5y divide by negative -5y cancel each other out leaving the y isolated.

-15 divided by -5 gives u positive 3.

So the answer is y=3

Answer: C. Sesame oil freezes at a lower temperature than peanut oil because −6.2 °C < 3.1 °C

Step-by-step explanation:

Given that:

Freezing point of sesame oil = - 6.2°C

Freezing point of peanut oil = 3.1°C

Comparing the two temperatures :

Freezing(when a substance turns to solid) usually occurs at low temperatures. The temperature of sesame oil(-6 2°C) is lower than that of peanut oil(3.1°C).

Hence, it can be concluded that Sesame oil freezes at lower temperature than peanut oil.

Mathematically,

-6.2°C < 3.1°C

(b) 5760000

Step-by-step explanation:

Total letters in English alphabet = 26

Total digits = 10

Given: Each automobile license plate number consists of two letters followed by a four-digit.

(a) If there are no restrictions, then the total number of license plates formed = 26 x 26 x 10 x 10 x 10 x 10

= 6760000

(b) if the letters O and I are not used, total letters can be used ]= 26-2=24

Then the total number of license plates formed = 24 x 24 x 10 x 10 x 10 x 10

=5760000
