At a track event, the distance y (in meters) traveled by student a in x seconds is represented by the equation y=9x. how many miles did student a travel in 1 second? in 2 seconds?

x = 0.00559234073 for 1 second

x = 0.0111846815 for 2 seconds

Step-by-step explanation:

We first need to know that 1 mile = 1609.344 meters to get one unit to use or else it'll be confusing.

For 1 second, x will be replaced by 1.

So:

y=9(1)

y=9

And for 2 seconds, x will be replaced by 2.

So:

y=9(2)

y=18

These are the measurements in meters. Then, we need to find what it is in miles.

So we can use a proportion for this.

1/1609.344 = x/9

1609.344x = 9

x = 0.00559234073 for 1 second

For 2 seconds:

1/1609.344 = x/18

1609.344x = 18

x = 0.0111846815 for 2 seconds

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
