Find a number less than 100 that is increased by one-fifth of its value when its digits are reversed.
zhannawk [14.2K]

Lets say the number is ab. Its value is 10a + b  

When it is reversed it is 10b + a = 12a+1.2b (from the condition its value should increase 0.2 times).  

11 a = 8.8b  

a/b = 8.8/11 = 0.8/1 = 8/10 = 4/5 ( we do this because a and b should be natural numbers less than 10).  

answer is 45.

the coordinates for the endpoints of a line segment are (-5,13) and (-9,21). find the coordinates for the midpoint of the line s
dedylja [7]
The midpoint of AB where A(x_A;\ y_A) and B(x_B;\ y_B)

\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)

A(-5;\ 13);\ B(-9;\ 21)

The midpoint of AB: \left(\dfrac{-5+(-9)}{2};\ \dfrac{13+21}{2}\right)=\left(\dfrac{-14}{2};\ \dfrac{34}{2}\right)=(-7;\ 17)

Answer: A. (-7, 17)

1. A cheetah can run at a top velocity of 31 m/s and has a mass of 47 kg. What is the cheetahs kenetic energy?
Naily [24]

Answer:

1. 22583.5 J

2. 1248 kg

3. 78.09 m/s

Step-by-step explanation:

The formula for kinetic energy is ;

K.E = 1/2* m * v²

Where m is the mass and v is the velocity

1.

K.E = 1/2 * m*v²

K.E = 1/2 * 47 * 31²

K.E = 22583.5 J

2.

Velocity = 9.78 m/s.

Kinetic energy = 60,800 J

To get mass, apply the formula as;

K.E = 1/2 * m*v²

60,800 = 1/2 * m * 9.78²

60800 = 48.70845 m

60800/48.70845 = m

1248 = m

Mass = 1248 kg

3.

K.E = 143.3 J

Mass = 0.047 kg

Apply the formula;

K.E = 1/2 * m*v²

143.3 = 1/2 * 0.047 * v²

143.3 = 0.0235 v²

143.3/0.0235 = v²

6097.87 = v²

v = √6097.87

v= 78.09 m/s
