Answer:
a. 2/3 or 0.6666...
b. AB = 6cm and AD = 3cm
Step-by-step explanation:
28/42 = 2/3
14/21 = 2/3
42*1/7 = 6
21*1/7 = 3
95000 Is rounded to the nearest ten thousands
So remember the formula for working out the slope:
(y2 - y1) ÷ (x2 - x1)
We already know two points:
(11, 5) and (20, 5) (Remember points are like (x, y)
Therefore y2 = 5 and y1 = 5 and x2 = 20 and x1 = 11
Substitute these into the formula from the start:
(y2 - y1) ÷ (x2 - x1)
(5 - 5) ÷ (20 - 11)
0 ÷ 9
And we can determine the slope is equal to 0 as 0 ÷ 9 = 0
Given:
ratio of stickers to erasers: 3 to 8
She has 12 stickers.
3:8 = 12:x
3x = 8*12
3x = 96
x = 96/3
x = 32 erasers.
Mrs. Robbins has 32 erasers.
