Answer:

The answer to your question is 1/5

Step-by-step explanation:

Data

-2, -1 4/5, -1 3/5, -1 2/5

Process

- Substract two continuos numbers

- 2 - (-1 4/5) = -2 + 1 4/5

= -2 + 9/5

= (-8 + 9) /5

= 1/5

- Check with another pair

-1 3/5 - (-1 2/5) = -8/5 + 7/5

= 1/5

Conclusion

The difference between the points is 1/5

Two planes are heading toward each other. One plane is traveling at 450 mph, and the other plane is traveling at 375 mph. What i

gavmur [86]

Answer:

the rate at which the distance between the planes is changing is 825 each hour

Step-by-step explanation:

The computation of the rate at which the distance between the planes is changing is shown below

= Travelling one plane + travelling another plane

= 450 mph + 375 mph

= 825 mi each hour

Therefore the rate at which the distance between the planes is changing is 825 each hour

We simply applied the above formula so that the correct value could come

And, the same is to be considered

Determine if y varies directly with x. Give the constant of variation, when appropriate. (picture below)

maxonik [38]

Based on the given variation, y does not vary directly with x and the constant of variation are 8, 3.2 and 1.25 respectively.

<h3>Variation</h3>

y = k × x

where,

k = constant of proportionality

y = -40

x = -5

y = k × x

-40 = k × -5

-40 = -5k

k = -40/-5

k = 8

when,

y = 8 and x = 2.5

y = k × x

8 = k × 2.5

8 = 2.5k

k = 8/2.5

k = 3.2

when,

y = 5 and x = 4

y = k × x

5 = k × 4

5 = 4k

k = 5/4

k = 1.25

Answer:

Step-by-step explanation:

Given, 

Dimensions of the rectangular prism = 9ft, 12ft and 4ft

Therefore, 

Surface area of the rectangular prism

= 2( lb + bh + lh)

$= 2(12 \times 9 + 9 \times 4 + 12 \times 4) {ft}^{2}$

$= 2(108 + 36 + 48) {ft}^{2}$

$= 2 \times 192 {ft}^{2}$

$= 384 {ft}^{2}$

Hence,

Surface area of rectangular prism is 384 sq. ft (Ans)
