Answer:
y = - 4.4
Step-by-step explanation:
from the question
y = -6.6
x = 9.9
y∝ x
y = kx ..... where k is introduced as a constant of proportionality
solve for k
y=-6.6 and x = 9.9
we have,
-6.6 = k × 9.9
-6.6 = 9.9k
divide both sides by 9.9
-6.6/ 9.9 = 9.9k/9.9
-0.667= k
therefore k = - 0.667
now, find y when x = 6.6
from the equation y = kx
y = -0.667 × 6.6
y = - 4.4
Answer:
750,000 kg·m/s
Step-by-step explanation:
Hi there!
Momentum = mass * velocity
Mass = 30,000
Velocity = 25
Momentum = 30,000 * 25
Momentum = 30,000 * 25
Momentum = 750,000
Therefore, the momentum of the truck is 750,000 kg·m/s.
I hope this helps!
Answer:
x = 17
Step-by-step explanation:
Since the triangles are similar then corresponding angles are congruent.
∠ I = ∠P ← substitute values and solve for x
3x + 4 = 72 - x ( add x to both sides )
4x + 4 = 72 ( subtract 4 from both sides )
4x = 68 ( divide both sides by 4 )
x = 17
Answer:
EG = 2 units
Step-by-step explanation:
Given that line q bisects EG at T , then
ET = TG ( substitute values )
x = x - 2 ( multiply through by 3 to clear the fraction )
x = 3x - 6 ( subtract x from both sides )
0 = 2x - 6 ( add 6 to both sides )
6 = 2x ( divide both sides by 2 )
3 = x
Then
ET = x = × 3 = 1
TG = x - 2 = 3 - 2 = 1
Thus
EG = ET + TG = 1 + 1 = 2 units
