Answer:

Speed = 600 mile per hour

Step-by-step explanation:

Given values:

Time = 3.25hours

Distance = 1950miles

Formula: speed = distance ÷ time

Therefore:

Speed = 1950 ÷ 3.25

Speed = 1950 ÷ 325/100

Speed = 1950 × 100/325

Speed= 195000/325

Speed = 600ml^h

Answer: The average speed of the plane is 600 miles per hour.

Step-by-step explanation:

The formula for determining average speed is expressed as

Average speed = total distance travelled/total time taken

The airplane flew from Chicago to San Francisco in 3.25 hours. Therefore, time = 3.25 hours

The cities are 1,950 miles apart. This means that the distance travelled is 1950 miles. Therefore,

Average speed = 1950/3.25 = 600 miles per hour.

Note: Consider we need to find the factor form of the given expression by taking out the GCF.

Given:

The expression is:

$-42k^3+24k^4+12k^5$

To find:

The factor form of the given expression.

Solution:

We have,

$-42k^3+24k^4+12k^5$

It can be written as:

$=6k^3(-7)+6k^3(4k)+6k^3(2k^2)$

Taking out the greatest common factor (GCF), we get

$=6k^3(-7+4k+2k^2)$

Therefore, the factor form of the given expression is $6k^3(-7+4k+2k^2)$ .

write The equation of the line that passes through the point parentheses (6 , 4) and is parallel to the equation 2X plus 3Y equa

aliina [53]

Answer:

2x + 3y - 24 = 0

Step-by-step explanation:

2x + 3y = 18

3y = -2x + 18

y = $\frac{-2}{3}$ x + 6

m = -2/3

y - 4 = -2/3(x - 6)

3y - 12 = -2x + 12

2x + 3y - 24 = 0
