Answer:
about 0.20
Step-by-step explanation:
The speed, acceleration, and distance satisfy the equation ...
v² = 2ad
So the acceleration is ...
a = v²/(2d) = (6 m/s)²/(2×9 m) = 2 m/s²
If we take the acceleration due to gravity to be 9.8 m/s², the coefficient of kinetic friction is the ratio of these:
k = (2 m/s²)/(9.8 m/s²) ≈ 0.20
Answer:
20 ipads
Step-by-step explanation:
16 divided by 4 (the ratio of computers)=4
(ipads) 5 multiplied by 4=20
16:20 = 4:5
So the classroom has 20 ipads
(sorry if its incorrect, hope this helps)
Answer:
2x + 3y > 6 (1)
3x – 2y = 9 (2)
x + 5y = 20 (3)
From (1) and (2), we have:
(2x + 3y) - (3x - 2y) > 6 - 9
5y - x > -3 (4)
From (3) and (4), we have:
(x + 5y) - (5y - x) > 20 - (-3)
2x > 23
x > 12,5 (5)
From (3) and (5), we have:
x + 5y = 20 ⇔ 12,5 + 5y > 20
5y > 7,5
y > 1,5
So: C = 4x + 3y > 12,5 × 4 + 1,5 × 3 = 50 + 4,5 = 54,5
Conclusion: C > 54,5
Given:
Vertices of a triangle ABC are A(-3,0), B(3,0) and C(0,4).
To find:
The intersection point of all the medians of the triangle ABC.
Solution:
We know that, intersection point of all the medians of a triangle is called centroid.
The formula of centroid is
Vertices of a triangle ABC are A(-3,0), B(3,0) and C(0,4).
Round each coordinate to the nearest tenth.
The coordinates of required point are (0,1.3). Therefore, the correct option is C.
