Answer:
You count how many significant figures there are and because it's division you see which one has the least amount. 1.3 only has two significant figures so the answer will only have 2 sig figs. So, 21.3 divided by 1.3 equals 16.385 but the answer is 16 because you only include 2 sig figs because that's how many are in 1.3. 21.3/1.3=16
Answer:
42
Step-by-step explanation:
The right answer is <span>(3) If a is positive, the parabola opens upwards</span>
Sum of interior angle of a triangle is 180 degrees.
2x + 4x + 9x = 180
15x = 180
x = 180/15 = 12
2x = 2 x 12 = 24
4x = 4 x 12 = 48
9x = 9 x 12 = 108
the measures of the angles are : 24 degrees, 48 degrees ,108 degrees
Answer:
A
Step-by-step explanation:
A. (1,3) and (6,3) have the same y-coordinate, so the distance between them is the difference of the x-coordinates.
distance = 6-1 = 5
:::::
B. (3,5) and (1,5). Again, the same y-coordinate. Distance = 3-1 = 2 ≠ 5
:::::
C. distance = 5-1 = 4 ≠ 5
:::::
D. distance = 3-2 = 1 ≠ 5
