Answer:

<h2>-  \frac{1}{4}</h2>

Step by step explanation:

\frac{3}{4}  \times ( \frac{ - 1}{3} )

Multiplying a positive and negative equals a negative:

( + ) \times ( - ) = ( - )

-  \frac{3}{4}  \times  \frac{1}{3}

Reduce the number with the greatest common factor 3

-  \frac{1}{4}

Hope this helps...

Good luck on your assignment...

Answer:

-1/4

Step-by-step explanation:

You multiply the numerators, 3 multiplied by -1=-3.

Then the denominators, 4 multiplied by 3=12.

This means the answer is -3/12, but then you can simplify it to -1/4.

Find an equation of the circle that satisfies the given conditions. Endpoints of a diameter are P(−2, 1) and Q(8, 9)
IrinaK [193]

Answer:

Equation of the circle   (x-3)²+(y-5)²=(6.4)²

                             x² -6x +9 +y² -10y +25 = 40.96

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given endpoints of diameter P(−2, 1) and Q(8, 9)

Centre of circle = midpoint of diameter

                   Centre = (\frac{-2+8}{2} ,\frac{1+9}{2} )

               Centre (h, k) = (3 , 5)

<u><em>Step(ii):-</em></u>

The distance of two end points

PQ = \sqrt{(x_{2}-x_{1} )^{2} +(y_{2} -y_{1} )^{2}  }

PQ= \sqrt{(8+2 )^{2} +(8 )^{2}  }

PQ = √164 = 12.8

Diameter    d = 2r

                 radius r = d/2

                Radius r = 6.4

<u><em>Final answer:-</em></u>

Equation of the circle  

                    (x-h)²+(y-k)² = r²

                   (x-3)²+(y-5)²=(6.4)²

x² -6x +9 +y² -10y +25 = 40.96

x² -6x  +y² -10y  = 40.96-34

x² -6x  +y² -10y -7= 0

Paco pago $105.0 por 10 tacos cual es el precio de cada taco si todos tienen el mismo precio
lora16 [44]

The price of each taco is $10.5

What is unitary method?

We can solve this question by unitary method.
The unitary method is a method of finding the value of one unit and then finding the value of the required number of units. While solving a problem it is important to recognize the units and values.


In this question, 10 tacos cost $105.
Let's represent the cost of 1 taco as x
10 tacos =$ 105
1 taco = x
10x = 105
x = \frac{105}{10}

x = 10.5
Each taco cost $10,5
