Answer:

3/5

Step-by-step explanation:

To find the slope, we use the formula

m = (y2-y1)/(x2-x1)

= (5-8)/(-2-3)

= -3/-5

=3/5

The slope is 3/5

$\bf c(\stackrel{x_1}{3}~,~\stackrel{y_1}{8})\qquad d(\stackrel{x_2}{-2}~,~\stackrel{y_2}{5}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{5-8}{-2-3}\implies \cfrac{-3}{-5}\implies \cfrac{3}{5}$

Mark cycled 25 miles at a rate of 10 minutes per hour. How long dis it take Mark to cycle 25 miles

Kobotan [32]

Answer:

2.5 hours.

Step-by-step explanation:

We have been given that Mark cycled 25 miles at a rate of 10 miles per hour.

To find how many hours Mark took to cycle 25 miles we will divide 25 by 10.

$\text{Time taken by Mark to cycle 25 miles}= \frac{25\text{ miles}}{10\frac{miles}{hour}}$

$\text{Time taken by Mark to cycle 25 miles}=\frac{25\text{ miles}}{10}\times \frac{\text{hour}}{\text{miles}}$

Upon cancelling out miles from numerator and denominator we will get,

$\text{Time taken by Mark to cycle 25 miles}=\frac{25}{10} \text{ hour}$

$\text{Time taken by Mark to cycle 25 miles}=2.5\text{ hour}$

Therefore, Mike will take 2.5 hours to cycle 25 miles.

V2=u2+2as v 2 = u 2 + 2 a s Where v v is the final velocity (in m/s), u u is the initial velocity (in m/s), a a is the accelerat

allsm [11]

Answer:

<em>Final velocity, v = 21.75 m/s</em>

Step-by-step explanation:

Given that the relation between final velocity, initial velocity, acceleration and distance traveled is expressed as:

$v^2=u^2+2as$

Also, given that:

Initial velocity, u = 9 m/s

Acceleration, a = 7 m/ $s^2$

Distance, s = 28 m

To find:

Final velocity, v = ?

Solution:

The given relation between v, u, a and s is:

$v^2=u^2+2as$

We have the values of initial velocity, acceleration and distance traveled in the question statement. We just need to put all these values to find the value of final velocity.

Let us put all the values in the given equation and try to find final velocity, v:

$v^2=9^2+2\times 7 \times 28\\\Rightarrow v^2=81+14 \times 28\\\Rightarrow v^2=81+392\\\Rightarrow v^2=473\\\Rightarrow v=\sqrt{473}\\\Rightarrow v=21.75\ m/s$

So, the answer is:

<em>final velocity, v = 21.75 m/s</em>

Readme [11.4K]

Answer:

5 1/2 or 5.5

Step-by-step explanation:

=8 1/2+2 1/6-5 2/12

=17/2+ 2 1/6-5 2/12

=17/2+13/6-5 2/12

=32/3- 5 2/12

=32/3-31/6

=11/2

=5 1/2

How do you change 2/5 to a precent

nikklg [1K]

Answer:

40%

Step-by-step explanation:

Percent is how much out of 100.

We have 2/5, so find equivalent fractions:

2/5 = 4/10 = 40/100

2/5 = 40%
