Amanda [17]

Answer:

a) 5,000 b) 3,600

Step-by-step explanation:

a) there are four different slots, and for the first three slots there are a possibility for 10 different numbers and in the last slot there can only be 5 different numbers. So you get 10 x 10 x 10 x 5 which leaves you with 5,000 possibilities

b) the same thing as above but know you have fewer numbers 10 x 9 x 8 x5 which gives you 3,600 possibilities

DENIUS [597]
3 boxes of computer diskettes at $8.99 per box = (3 * 8.99 = 26.97 ) 
2 packages of pens at $ 2.50 per package = (2 * 2.50 = 5.00 ) 
6 boxes of paper at $ 22.95 per box = (6 * 22.95 = 137.70) 
1 printer ribbon at $25 each. = (1 * 25 = 25) 
Add up (26.97+5.00+137.70+25 ) and the answer is = 194.67

Please help …………………….

Answer:

  (-3, 3)

Step-by-step explanation:

The blanks are trying to lead you through the process of finding the point of interest.

__

The horizontal distance from T to S is <u> 9 </u>. (or -9, if you prefer)

The ratio you're trying to divide the line into is the ratio that goes in this blank:

Multiply the horizontal distance by <u> 2/3 </u>. (9×2/3 = 6)

Move <u> 6 </u> units <u> left </u> from point T.

The vertical distance from T to S is <u> 6 </u>.

Multiply the vertical distance by <u> 2/3 </u>. (6×2/3 = 4)

Move <u> 4 </u> units <u> up </u> from point T.

__

Point T is (3, -1) so 6 left and 4 up is (3, -1) +(-6, 4) = (3-6, -1+4) = (-3, 3). The point that is 2/3 of the way from T to S is (-3, 3).
