Answer:

The product of the expression is -12s² + 11st - 2t²

Step-by-step explanation:

(-3s + 2t)(4s - t)

Use the foil method to multiply the terms. So, we distribute -3s to (4s - t) and we will also distribute 2t to (4s - t) as well.

-12s² + 3st + 8st - 2t²

Now combine like terms.

-12s² + 11st - 2t²

Answer:

yes

Answer:

no

Step-by-step explanation:

The third side must be less than the sum of the other two sides

5+5> the third side

10 > third side

Since the third side is 10 we cannot build a triangle

Answer:

6%

Step-by-step explanation:

[tex]\frac{213590 - 201500}{201500} = \frac{12090}{201500} = 6[/tex]

The percentage profit Emma makes. if, Emma buys a house for £201 500, and She sells the house for £213 590 is 6%.

As it is clear from the term per cent means measuring anything per hundred. For example, you get marks per 100 marks, so you get the percentage.

Given:

Emma buys a house for £201 500,

She sells the house for £213 590,

Calculate the profit as shown below,

Profit = Selling price of the house - Cost of house

Profit = 213 590 - 201 500

Profit = £12090

Calculate the percentage profit as shown below,

The percentage profit = Profit / Cost of house  × 100

The percentage profit = 12090 / 201500 × 100

The percentage profit = 0.06 × 100

The percentage profit = 6%

Answer:

A Analía sí le alcanzó el dinero pues aún tenía $224 de los $2000 que llevó.  

Analía gastó en total $1776. Si llevó $2000, entonces aún tenía:

[tex] \\ \$2000 - \$1776 = \$224[/tex]

Step-by-step explanation:

Para resolver el problema se deben obtener los subtotales de cada una de las transacciones en los que Analía gastó el dinero:

Primera transacción: compra de 12 camisas

Compró 12 camisas a $21 cada una. El monto por esta transacción es:

[tex] \\ \frac{\$21}{camisa} * 12\;camisas = \$252[/tex]

Primera transacción: T1 = $252.

Segunda transacción: compra de 24 remeras

Compró 24 remeras a $11 cada una:

[tex] \\ \frac{\$11}{remera}*24\;remeras = \$264[/tex]

Segunda transacción: T2 = $264.

Tercera transacción: compra de 40 polleras

Compró 40 polleras a $56 cada una:

[tex] \\ \frac{\$56}{pollera}*40\;polleras = \$2240[/tex]

Tercera transacción: T3 = $2240.

Cuarta transacción: devolución de pantalones y descuento

Devolvió 20 pantalones (y se lo descontaron de lo que tenía que pagar). El costo de cada pantalón es de $51 cada uno:

[tex] \\ \frac{\$51}{pantalon}*20\;pantalones = \$1020[/tex]

Cuarta transacción: T4 = $1020.

Quinta transacción: pago de ida y vuelta en transporte

Finalmente, el taxi para ir y volver del negocio le costó $40.

Quinta transacción: T5 = $40.

¿Cuánto gastó en total Analía?

A todo lo que Analía gastó, le debemos restar lo obtenido en el descuento por la devolución de pantalones (Cuarta transacción). Este último dinero corresponde a una transacción a favor de Analía, por lo que se resta a lo que ella ha gastado. De esta manera:

[tex] \\ Total = T1 + T2 + T3 - T4 + T5[/tex]

[tex] \\ Total = \$252 + \$264 + \$2240 - \$1020 + \$40[/tex]

Para hacer más notorio el total de lo que gastó y lo que le descontaron a su favor, tenemos:

[tex] \\ Total = \$252 + \$264 + \$2240 + \$40 - \$1020[/tex]

[tex] \\ Total = \$2796 - \$1020[/tex]

[tex] \\ Total = \$1776[/tex]

Entonces, Analía gastó en total $1776. Si llevó $2000, entonces aún tenía:

[tex] \\ \$2000 - \$1776 = \$224[/tex]

En conclusión, a Analía sí le alcanzó el dinero pues aún tenía $224 de los $2000 que llevó.

Answer: 2,000 milliliters.  

Step-by-step explanation:

Hi, to answer this question we have to add the amount of water and the amount of sports drink that he drank:

1 liter + 1 liter = 2 liters of liquid.

Finally, we have to convert the result into milliliters.

Since 1 liter = 1000 liters

We have to multiply the liters drank by 1000.

2 x 1000 = 2,000 milliliters.

Answer:

The percentage of the substance is left after 10 hours is 60%.

Step-by-step explanation:

The expression representing the amount left after a certain period of decay is:

[tex]y=a(1-r)^{t}[/tex]

Here,

y = final amount

a = initial amount

r = decay rate

t = time taken

It is provided that:

a = 1

r = 5% / hour

t = 10 hours

Compute the percentage of the substance is left after 10 hours as follows:

[tex]y=a(1-r)^{t}[/tex]

  [tex]=1\times (1-0.05)^{10}\\\\=0.95^{10}\\\\=0.598737\\\\\approx 0.60[/tex]

The percentage is: 0.60 × 100 = 60%.

Thus, the percentage of the substance is left after 10 hours is 60%.

Answer: 64,000 crickets

Step-by-step explanation: 2 years = 24 months; every 3 months the crickets double in population, therefore the cricket population doubles 8 times. 250 x 2 = 500; 500 x 2 = 1,000; 1,000 x 2 = 2,000; 2,000 x 2 = 4,000; 4,000 x 2 = 8,000; 8,000 x 2 = 16,000; 16,000 x 2 = 32,000; 32,000 x 2 = 64,000

Answer:

see below

Step-by-step explanation:

h(t) = –gt^2 + v0t + h

where g is 1/2 the gravity constant and v0 is the initial velocity and h is the initial height

h(t) = –16t^2 +49t + 0

h(t) = –16t^2 +49t

Factor out t

0 = t(-16t+49)

The zeros are at

t= 0 and   -16t = -49

                      t = 49/16

The vertex  (or max) is 1/2 way between the zeros

(0+ 49/16)  /2 = 49/32  =1.53125

Round to the nearest hundredth

x = 1.53

The height is

h(1.53) = 1.53(-16 * 1.53 +49)

          37.5156

To the nearest hundredth

           37.52

The range is the values that height can take

0 ≤h≤37.52

There is a maximum height because eventually the effects of gravity going down outweigh the effects of the initial velocity going up

Answer:

Maria (I THINK)

Step-by-step explanation:

Tanya is running 70 yards in all, while maria would be running more based on the pythagorean theorem

The pythagorean theorem is that on a right triangle, the square root of the two legs equal the hypotenuse

40^2+ 70^2 =c^2

6500=c^2

square root both sides

and roughly c= 80.6 yards so maria runs more

Answer:

Interest =$360

Balance =$960

Step-by-step explanation:

Interest = Principal *Rate * Time

             = $360

∴ The balance will be $600 + 360 = $960

Answer:

smaller x = -2

larger x = 4

vertex: (1, -9)

Step-by-step explanation:

To find the zeros of the function, set each value in parenthesis to 0 separately.

Smaller x:

(x+2) = 0

x = -2

Larger x:

(x-4) = 0

x = 4

To find the vertex of the parabola you need to find the x value between the zeros.

[tex]\frac{4 + (-2)}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1

Plug 1 in for x in the equation.

f(x) = ((1) + 2)((1) - 4)

f(x) = (3)(-3)

f(x) = -9

When x = 1, f(x) = -9, so the vertex of the parabola is at (1, -9).

Answer: $210000

Step-by-step explanation:

2:5:5:7

you add the numbers that are in the ratio

2+5+5+7= 19

Then you divide each four of the profits by the total profit

2/19 x 570000 = $60000

5/19 x 570000 = $150000

7/19 x 570000 = $210000

Therefore the largest amount of profit recieved by one of the four partners is $210000

Answer:

V = 84.82 ft³

Step-by-step explanation:

Volume of Cone = [tex]\pi r^2\frac{h}{3}[/tex]

Where r = 3, h = 9

=> V = (3.14)(9)(3)

=> V = 84.82 ft³

The answer is 30

Step-by-step explanation:

It is 30 because if there is 75 and the total needs to be 105 then you have to add 30+75+105! Thats the answer.

I got it right! :)

The CBD angle is 30 degrees. 

An angle is formed when two straight lines or rays meet at a common endpoint.

Given that the measure of angle ABD is 105º and the measure of angle ABC is 75º.

According to the given figure, the relation between angles is given by

angle ABD = angle ABC + angle CBD

Let x be the angle CBD then

105 = 75 + x

i.e  x = 105 - 75 = 30

Hence the angle CBD is 30°.

The maximum number of sandwiches she can buy is 24.

Step-by-step explanation:

We can create a function to represent the cost of her team's lunch in function of the number of people in the team. We have:

[tex]cost(x) = 15 + 6.25*x[/tex]

Since she needs to stay on budget, the cost has to be less or equal to 170, therefore:

[tex]cost(x) \leq 170\\15 + 6.25*x \leq 170\\6.25*x \leq 170 - 15\\x \leq \frac{155}{6.25}\\x \leq 24.8[/tex]

Since she can't buy 0.8 sandwiches, the maximum number of sandwiches she can buy is 24.

Step-by-step explanation:

Answer: No solution

Both tables have slope 2 (y increases two for every increase of 1 in x).  First has y intercept 5, second 15  (19=2(2)+b).  So our system is

y = 2x + 5

y = 2x + 15

Those are parallel lines, which never meet, so no solution.
