Answer:

56 and 16

Step-by-step explanation:

Set up equations!

x+y=72

x-y=40

You can solve for this by crossing out y as it becomes eliminated. You are left with 2x= 112. Then solve, so x= 56. Take 56 for x and plug it into one of the equations and solve for y. 56-y=40-----> y= 16. The numbers are 16 and 56.

Using a system of equations, it is found that the numbers are 16 and 56.

Their sum is of 72, thus:

[tex]x + y = 72 \rightarrow y = 72 - x[/tex]

Their difference is of 40, thus:

[tex]x - y = 40[/tex]

Since [tex]y = 72 - x[/tex]

[tex]x - (72 - x) = 40[/tex]

[tex]2x = 112[/tex]

[tex]x = \frac{112}{2}[/tex]

[tex]x = 56[/tex]

Then:

[tex]y = 72 - x = 72 - 56 = 16[/tex]

The numbers are 16 and 56.

Answer: To find the percentage of the down payment to the purchase price, just multiply the down payment by 100 and divide the result by the   purchase

i.e 15,000 x 100/ 150,000= 10%

Also for the second part, multiply the down payment by 100 and divide by the purchase price

i.e 67,500 x 100 / 150,000= 45%

Step-by-step explanation:

At a Baseball Match.

35% of spectators are New York Yankees fan

The rest are Boston Red Sox fan = 100 - 35% = 65%

30% of fans in both teams are females.

30% of 35% of spectators are New York Yankees fan = 0.105 females

30% of 65% of spectators are Boston Red Sox fan = 0.195 females

The number of males in New York Yankees fan = 1 - 0.105 females

= 0.895 males

The number of males in Boston Red Sox fan = 1 - 0.195 females

= 0.805 males

[tex]\left(-t^4-5t^3-10t^2\right)+\left(9t^3+3t^2-1\right)=-t^4+4t^3-7t^2-1[/tex]

Step-by-step explanation:

Given the expression

[tex]\left(-t^4\:-5t^3\:-10t^2\:\right)+\left(9t^3\:+3t^2\:-1\right)[/tex]

Remove parentheses:  (a)=a

[tex]=-t^4-5t^3-10t^2+9t^3+3t^2-1[/tex]

Group like terms

[tex]=-t^4-5t^3+9t^3-10t^2+3t^2-1[/tex]

Add similar elements        

[tex]=-t^4-5t^3+9t^3-7t^2-1[/tex]         ∵ [tex]-10t^2+3t^2=-7t^2[/tex]

Add similar elements        

[tex]=-t^4+4t^3-7t^2-1[/tex]                  ∵  [tex]-5t^3+9t^3=4t^3[/tex]

Thus, the equivalent expression in simplified form:

Step-by-step explanation:

Answer:

y = 4x + 3

[ x ][ -2 ][ -1 ][ 0 ][ 1 ][ 2 ]

[ y ][ -5 ][ -1 ][ 3 ][ 7 ][ 11 ]

y = 4(-2) + 3 y = 4(-1) + 3 y = 4(0) + 3 y = 4(1) + 3 y = 4(2) + 3

y = -8 + 3 y = -4 + 3 y = 0 + 3 y = 4 + 3 y = 8 + 3

y = -5 y = -1 y = 3 y = 7 y = 11

Answer:

La oferta 2 oferce el mayor valor final. Es la que debería ser aceptada.

Step-by-step explanation:

Dada la siguiente información:

Oferta 1:

$150.000 hoy y $200.000 dentro de 10 años.

Oferta 2:

$30.000 al final de cada uno de los próximos 10 años.

Tasa de interés= 14%

Para decidir cuál de las dos ofertas es mejor, debemos calcular el valor final:

Oferta 1:

VF= VP*(1+i)^n

VF= 150.000*(1,14^10) + 200.000

VF= $2.261.523,48

Oferta 2:

VF= {A*[(1+i)^n-1]}/i

A= cash flow anual

VF= {30.000*[(1,14^20) - 1]} / 0.14

VF= $2.730.747,83

Answer:

they have 24 part time employees

Step-by-step explanation:

multiply 30 by .8 (which is 80% in decimal form) and you get 24. subtract that from 30 and you get 6 extra employees. 24 is the answer.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

100% = 30

80% = 24

The number of employees who work part-time is 24.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of employees = 30

80% of the employees work part-time.

This means,

80% of 30

= 80/100 x 30

= 24

Thus,

The number of employees who work part-time is 24.

Given :

An airplane cuts through the morning sky for every 1,000 feet that he climbs the outside temperature drops 20° F.

To Find :

The rate of the temperature change in degrees Fahrenheit per foot.

Solution :

Let, rate of the temperature change in degrees Fahrenheit per foot is x.

So,

[tex]x = \dfrac{20}{1000}\ ^oF/foot\\\\x = 0.02 ^oF/foot[/tex]

Therefore, rate of the temperature change in degrees Fahrenheit per foot is 0.02.

Hence, this is the required solution.

Answer:

this is really late, but for the people who need it now the real answer is

Step-by-step explanation:

The airplane is rising, so the change in elevation is +1,000 feet. The temperature is dropping, so the change in temperature is -20 degrees Fahrenheit.
