An airplane is flying from New York City to Los Angeles. The distance it travels in miles d, is related to the time in seconds,
34kurt

Answer:

A. 0.15

B. 0.45

C. 85

Step-by-step explanation:

Given that:

Equation to represent the relation between distance, d in miles and time t in seconds:

d=0.15t

<em>A. </em>

To find: The speed of airplane in miles per second.

Formula for speed is given as:

Speed = \dfrac{Distance}{Time}

Here, we will have to find the value of \frac{d}{t}.

Dividing the given equation by t, we get:

\dfrac{d}{t}=0.15

d is in miles and t is in seconds.

Therefore, the answer is <em>0.15</em>.

<em>B.</em>

Distance traveled in 30 seconds.

Given that: t = 30 seconds

To find: d = ? in miles

d = 0.15\times 3 = 0.45

<em>C.</em>

The time taken to travel a distance of 12.75 miles.

Given that : d =12.75\ miles

To find: t = ? seconds

12.75 = 0.15t\\\Rightarrow t = \dfrac{12.75}{0.15}\\\Rightarrow \bold{t = 85}

Mahmoud spent 1/6 of the working in the flower bed Mahmoud spent 2/3 of that time adding mulch of the flower bed what fraction o
xz_007 [3.2K]

Answer: 1/9

Step-by-step explanation:

Since 1/6 of the day was spent in the flower bed and 2/3 of that was spreading mulch, we need to find 2/3 of 1/6 to find out how much of the day was spreading the mulch.

In math "of" means times

"is" means equals

2/3 of 1/6 is

 

translates to

2/3 x 1/6 =

Now we just multiply the numerators across and denominators across then reduce if possible...

2/3 x 1/6 = 2/18

2 and 18 both divide by 2 so it reduces

2/18 = 1/9

A relation is not a function if________.
jenyasd209 [6]

Answer:

A relation is not a function if it repeats its input values, or x values.

Step-by-step explanation:

For example, the relation 4,3   3,6   7,5  ,3,8 would not be a function because it repeats the x value of 3 in the points 3,6 and 3,8.

The relation 4,3 3,6 7,5 and 8,3 would be a function because it does not repeat the input values.

Hope this helps!
