Answer:

9 units or D

Step-by-step explanation:

The two numbers are 9 units apart as when you have -3, it takes positive 3 to get to 0. From 0 to 6 it is obviously 6. When you add 6 and 3 you get 9.

Suppose A and B are points. How many distinct lines contain both A and B?
Westkost [7]

Answer:

The correct option is;

1

Step-by-step explanation:

A line in geometry is an array of points that lay on the path of a ray and extends along the ray path in both directions infinitely, while a point in geometry marks a location

Therefore, given that the points A and B are on the same line, and are therefore on the same ray that gives the direction of the line, the number of distinct lines that can contain the both A and B, given that the original line extends to infinity in both direction is 1.

Answer:

  a) CP = SP/1.1

  b) CP = $59.50

  c) GST = $5.95

Step-by-step explanation:

a) Divide by the coefficient of CP.

  SP = 1.1×CP

  CP = SP/1.1

__

b) Use the formula with the given value.

  CP = $65.45/1.1 = $59.50

__

c) You can do this two ways: subtract CP from SP, or multiply CP by 0.1.

  GST = SP -CP = $65.45 -59.50 = $5.95

  GST = CP×0.10 = $59.50 × 0.10 = $5.95

Jack picked 10 ears of corn. He and two of his sisters ate two each. What is the amount of corn left represented as a
Burka [1]

<u>ANSWER: </u>

Jack picked 10 ears of corn. The amount of corn left is \frac{2}{5} ears of initial corn.

<u>SOLUTION: </u>

Given, Jack picked 10 ears of corn.  

Now the total corn present is 10 ears.

He and two of his sisters ate two each.

Then, remaining corn = 10 ears – eaten corn

= 10 – 2 (by him) – 2 (by his first sister) -2 (by his second sister)

= 10 – 6  = 4  

Now, the amount of corn left in fraction is remaining corn divided by initial corn.

Left over corn = \frac{remaining corn}{initial corn}

= \frac{4}{10} = \frac{2}{5}

Hence, the amount of corn left is \frac{2}{5} ears of initial corn.
