Answer:
10
Step-by-step explanation:
X+(x+1)+(x+2)+(x+3)+(x+4)+(x+5)=393
6x+15=393
6x=393-15
6x=378
x=63
third one is 63+2=65
The answer is 13.25
67+92= 159
159 divided by 12= 13.25
Using the given center and point at the circumference, the equation of the circles are:
- a)
- b)
- c)
<h3>
What is the equation of a circle?</h3>
- The equation of a circle of radius r and center is given by:
Item a:
- Center C(5,2), hence .
The point at the circumference is A(11,10), hence:
Hence:
Item b:
- Center C(-2,-5), hence .
The point at the circumference is A(3,-17), hence:
Hence:
Item c:
- Center C(5,-1), hence .
The point at the circumference is A(-2,-5), hence:
Hence:

Answer:
Margarita gastó <u>$40.43.</u>
Step-by-step explanation:
Tenemos la siguiente información.
<u>km recorridos por Margarita</u>
42 km - ciudad
387 km - autopista
<u>Rendimiento del carro</u>
1 galon cada 28 km - ciudad
1 galon cada 36 km - autopista
Hacemos el siguiente factor de conversión
<u>Ciudad</u>
<u>Autopista</u>
Ahoa, se sabe que 1 galon cuesta $3.30. Por lo tanto, el costo de viaje será:
Total galones = 1.5 + 10.75 = 12.25 galones
Total costo = 3.30*12.25 = $40.43.
