Mike is driving a boat at 12 mph and is increasing his speed by 0.2 mph each second. Hank is driving a boat at 26.4 mph and is d
VLD [36.1K]

Answer: After 16 seconds the boats will be traveling the same speed.

Step-by-step explanation:

Given: Mike is driving a boat at 12 mph and is increasing his speed by 0.2 mph each second.

Mike's spewed after x seconds = 12 + 0.2x

Hank is driving a boat at 26.4 mph and is decreasing his speed by 0.7 mph each second.

Hank's speed after x seconds = 26.4 -0.7 x

As per given,

12 + 0.2x =  26.4 -0.7 x

Subtract 12 from both sides

0.2x= 26.4-12-0.7x

⇒ 0.2x= 14.4-0.7x

Add 0.7xn on both sides , we get

0.2x+0.7x= 14.4

⇒ 0.9x = 14.4

Multiply 10 on both sides, we get

9x=144

Divide both sides by 9 , we get x= 16

Hence, after 16 seconds the boats will be traveling the same speed.

If (x, 1/100) lies on the graph of y = 10x, then x =
Vladimir79 [104]

Answer:

    1

--------- = x

1000

Step-by-step explanation:

Copy down  y = 10x.

Then substitute 1/100 for y:  

   1

-------- = 10x

 100

Divide both sides by 10 to isolate (solve for) x:

    1

--------- = x

The short-Run Macroeconomic Model is very similar to the standard model for markets. In what ways are these two models different
Semmy [17]

Answer: Option (c) is correct

Step-by-step explanation:

Slope of demand curve is negative and slope of supply curve is positive in both the models.

But labeling of axis is different in both the models. In the short-run macroeconomic model, y-axis represents the price level whereas x-axis represents the GDP.

While in the standard model for markets, y-axis shows the general price level whereas x-axis represents the output level.

Additive inverse of 400
Goshia [24]

Given:

A number is 400.

To find:

The additive inverse of 400.

Solution:

We know that the sum of a number and its additive inverse is 0.

If "a" is number and "b" is its additive inverse, then

a+b=0

Let x be the additive inverse of 400. Then,

400+x=0

Subtract both sides by 400.

400+x-400=0-400

x=-400

Therefore, the additive inverse of 400 is -400.
