Answer: A composite number can be divided into a whole number other than itself and one. A prime number can only be divided by itself and one.

Step-by-step explanation: Ex: 1,2,3,5,7,11,13, etc are prime. 4,6,8,9, etc are composite numbers. So... the first list is correct because 6 (3*2), 24(6*4), 51 (3*17), 105 (5*21) can all be multiplied by integers other than itself and one.

A plumber charges $50 to come to a house and $20 an hour for work time.
PolarNik [594]
Since the 50 remains the same every time, is has no letters next to it in the equation.  The 20, however, is multiplied by the amount of hours, and will therefore have an h next to.  

20h + 50- the answer is a.

X+2y=8<br>2x-y=1<br>mathe question​
Ira Lisetskai [31]

Answer:

x = 2 and y = 3

Step-by-step explanation:

We have

x+2y = 8 -----equation (i)

2x-y = 1 -----equation (ii)

Now,

x+2y = 8

or, x = 8-2y ------equation (iii)

Again,

2x-y = 1

or, 2x = 1+y

or, 2x-1 = y

Putting the value of 'x' from equation (iii)

or, 2(8-2y)-1 = y

or, 16-4y-1 = y

or, 16-1 = y+4y

or, 15 = 5y

or, y = 15/5

or, y = 3

Putting the value of 'y' in equation (iii)

x = 8-2y

or, x = 8-(2×3)

or, x = 8-6

or, x = 2

Therefore, x = 2 and y = 3.

The velocity,v of a missile is related to time t, By the equation v=5t^2+3t+1.calculate the time at which the velocity is minimu
Cloud [144]

Answer:

  • time: t = -0.3
  • minimum: v = 0.55

Step-by-step explanation:

For quadratic ax^2 + bx + c, the extreme value is found at x=-b/(2a). For your quadratic, the minimum is found at ...

  t = -(3)/(2(5))

  t = -0.3 . . . . . time of minimum velocity

__

The value of velocity at that time is ...

  v = 5(-0.3)^2 +3(-0.3) +1 = 5(.09) -.9 +1

  v = 0.55 . . . . . value of minimum velocity
