Los dueños de un restaurante cultivan sus propios

Answer:

Quedan 2.083 m^3 de agua en el reservorio.

Equivalen a 2083 litros.

Step-by-step explanation:

Los dueños del restaurante tienen un reservorio de agua cuyo volumen es de 6.25 m^3.

Si han utilizado 2/3 del reservorio, esto implica que aún quedan en el reservorio una tercera parte del volumen original (1/3).

Entonces, la cantidad de metros cúbicos (m^3) de agua que quedan en el reservorio se puede calcular como:

V=(1/3)\cdot V_0=(1/3)\cdot6.25\,m^3=2.083\,m^3

Este valor equivale a un volumen en litros de:

V=2.083\,m^3\cdot \dfrac{1,000\,l}{1m^3}=2,083\,l

A department store sold 62 shirts one day. All short-sleeved shirts cost $11.00 each and all long-sleeved shirts cost $17.00 eac
slava [35]

Answer:

a. Short-Sleeve = 35

b. Long-Sleeve = 27

Step-by-step explanation:

Given data:

Total shirts sold = 62

short sleeved cost = 11 each

Long sleeved cost = 17 each

Total receipts = 844

<em>Let the count of short sleeved be X  and Let the count of long sleeved be Y</em>

X + Y = 62 <em>(equation 1) from the total shirts sold</em>

11X + 17Y = 844 <em>(equation 2) from the total receipts</em>

<em>From equation 1</em>    X = 62 - Y <em>(Equation 3)</em>

<em>Substituting equation 3 into equation 2</em>

11(62 - Y) +17Y = 844

682 -11Y + 17Y = 844

-11Y + 17Y = 844-682

6Y = 162

Therefore Y = 27

<em>Substituting Y into equation 3</em>

X = 62 - Y

X = 62 - 27

X = 35

Answer:

Step-by-step explanation:

3. slope of CB = rise/run = 5/12      BF = 5    CF = 12

BF ⊥ DF

DB (seg of two farthest points) = √BF²+DF² = √5²+32² = √1049 = 32.4

4. f(x) = 2x² - 5x -3      vertex : A (h,k)  for f(x) = ax² + bx +c

h = - b/2a = - (-5 / 4) = 5/4

f = f(h) = 2*(5/4)² - 5*(5/4) - 3 =25/8 - 25/4 -3 = -49/8

A (5/4 , - 49/8) i.e. (1.25 , - 6.13)

negative root:   2x² - 5x -3 = (2x+1) (x- 3)      x = - 1/2      y = 0

B (- 1/2 , 0)

x coordinate of AB: 1/2 (1.25 + -0.5) = 0.375

  1. Simple interest = (principal×rate×time)÷100. *brackets first*
  2. transpose the formula to make rate the subject: rate= (100×simple interest) ÷ (principal×time)
  3. plug in values: rate = (100×37975) ÷ (31000×5)
  4. the result is 24.5%
