Answer:

Square root and the power of 2 cancel each other. The answer remain 4/7

The square of a number is the number times itself. For example the square of 3 is 3x3. The square of 4 is 4x4.

The square root is just the opposite of the square. You can think of it as the "root" of the square or the number that was used to make the square.

2. Flying to Kampala with a tailwind a plane averaged 158 km/h . On the return trip the plane only averaged 112 km/h while flyin

stiv31 [10]

Answer:

Speed of plane in still air = 135 km/h

Speed of wind = 23 km/h

Step-by-step explanation:

Given that:

Speed of plane with the wind = 158km/h

Speed of plane against the wind = 112km/h

Let,

x be the speed of plane

y be the speed of wind

According to given statement;

x+y = 158 Eqn 1

x-y = 112 Eqn 2

Adding Eqn 1 and 2

$x+y+x-y=158+112\\2x = 170\\\frac{2x}{2}=\frac{270}{2}\\x=135$

Putting x = 135 in Eqn 1

135+y = 158

y = 158-135

y = 23

Hence,

Speed of plane in still air = 135 km/h

Speed of wind = 23 km/h

If you know the equation of a proportional relationship how can you draw the graph of the equation

zalisa [80]

The equation of proportional relationship is of the form:
$y(x)=mx$

where m is the slope.

Drawing it is fairly easy, you start from the origin (0, 0) and you draw a diagonal staight line. The inclination of the line depends on the value of m. See picture attached.
