Speed of the train = 180km/hr
Now, distance from Grenoble to Paris = 480 km
Speed = Distance/Time
We know the speed and distance.So, from this we can find time :)
180 km/hr = 480 km /Time
Time = 480/180 = 2.66 hrs ≈ 2.7 hr
Therefore, the answer is D.2.7 hr
Equivalent to 180 degrees.
90 degrees clockwise +90 degrees
Answer:
A proportional relationship is there.
Step-by-step explanation:
Here in the table, the values of y are given corresponding to the values of x.
There are four sets of values of x and y.
We have to check whether the relationship is proportional or not.
Now, rate of change of y with respect to x will be from the first two pair of values is =
Again, rate of change of y with respect to x will be from the second two pair of values is =
And, rate of change of y with respect to x will be from the third two pair of values is =
So, the rate is always 0.75.
Therefore, a proportional relationship is there. (Answer)
Changing those words into an equation, we get:
7+3x = 19
Subtract both sides by 7
3x = 12
Divide both sides by 3
x = 4
That number is 4. Have a nice day! :)
Answer:
x = 7, x = 5
Step-by-step explanation:
Given 2 intersecting chords, then
The product of the parts of one chord is equal to the product of the parts of the other chord.
(1)
27x = 9 × 21 = 189 ( divide both sides by 27 )
x = 7
(2)
12(3x - 5) = 120 ( divide both sides by 12 )
3x - 5 = 10 ( add 5 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
