2.789=2 ones and 7 tenths 8 hundreths 9 thousandths
200/5 = 40 mph 200/4 = 50 mph Let x be the speed in still waters and y the speed of current. x + y = 50 x - y = 40 ADD 2x = 90 x = 45 mph ANSWER is C) 2) C
Answer:
See below
Step-by-step explanation:
<em>Vector argument</em>
Vector DF is (5, -4) - (5, 5) = (0, -9).
Vector EG is (2, 2) - (8, 2) = (-6, 0).
The dot-product of these two vector is (0, -9)•(-6, 0) = 0·(-6) + (-9)·0 = 0.
When the dot-product of two vectors is zero, those vectors are at right-angles to each other. Therefore diagaonal DF ⊥ diagonal EG.
_____
<em>Alternate argument</em>
The x-coordinates of points D and F are the same, so diagonal DF is a vertical line. The y-coordinates of points E and G are the same, so diagonal EG is a horizontal line. Vertical lines are perpendicular to horizontal lines, so DF ⊥ EG.
Answer:
Subtract 10 from both sides

Answer:
Three equivalent ratios would be 5/6, 20/24 and 30/36
Step-by-step explanation:
In order to find equivalent ratios, we need to multiply or divide both numbers by the same amount. First, lets divide both by 2.
10/2 = 5
12/2 = 6
5/6
Next we can multiply both by 2
10*2 = 20
12*2 = 24
20/24
Next we can multiply both by 3
10*3 = 30
12*3 = 36
30/36
